Background: Cutaneous manifestations of coronavirus disease 2019 (COVID-19) are not uncommon and can be the presenting sign of the disease. We aimed to investigate the cutaneous manifestations in COVID-19 patients.Methods: This cross-sectional study was performed on COVID-19 patients referred to Shohada-e Tajrish and Modarres hospitals, Tehran, Iran, from January 1, 2021 to March 31, 2021. Patients with cutaneous lesions were included in the study; if needed, patients were visited in person, and a biopsy was taken.Results: Of the 100 COVID-19 patients in this study, with a mean age of 45.53 ± 17.75 years, 37 (37%) were males. The most common cutaneous manifestation was urticaria (21%), followed by maculopapular eruptions (17%), petechiae/purpura (15%), pityriasis rosea-like lesions (15%), erythema multiforme (7%), pernio (6%), Vesicles/pseudovesicles/bullae (5%), and others (24%). Most lesions were erythematosus (87.63%). Legs (40%) were most frequently involved. The most common accompanying symptom was pruritus (52%), followed by burning sensations (18%) and pain (7%). Six patients had mucosal lesions; these lesions were the only mucocutaneous manifestations in three of them. Skin biopsies were taken from 11 patients, revealing epidermal changesin 10 (90.9%), dermal changes in 7 (63.6%), mucin deposition in 1 (9.1%), perivascular lymphocyte infiltration in 10 (90.9%), and neutrophil infiltration in 1 (9.1%).Conclusion: The frequency of skin manifestations was relatively high in this study, with urticaria as the most common cutaneous presentation of COVID-19. Special attention must be paid to the cutaneous lesions of COVID-19.

Background: Complications of chemotherapy most commonly involve highly proliferative cells, including the skin and its appendages and mucosa. This study evaluated mucocutaneous complications of chemotherapy in children with cancer.Methods: This descriptive cross-sectional study involved 92 children who received chemotherapy at the Pediatric Oncology Ward of Afzalipour Hospital, Kerman, Iran, between September 2018 and March 2019. Demographic and clinical features of the patients were collected by history, physical examination, and laboratory tests (biopsy, fungal and bacterial smears if necessary). Frequency and percentage were used for qualitative analysis. Mean ± standard deviation was used for quantitative analysis.Results: The mean age of patients was 6.60 ± 3.70 years (range 1 to 16 years). More than half of the patients (55.4%) were males. The most common malignancy was acute lymphocytic lymphoma (ALL). More than half of the children (60%) had mucocutaneous complications due to chemotherapy; these were significantly more common in boys than girls (70.6% vs. 48.8%). The mean age of children with mucocutaneous complications (7.41 ± 3.98) was significantly higher than those without complications (5.33 ± 2.84). The most common mucocutaneous side effects were, in order, alopecia, mucositis, and skin infections.Conclusion: We found that side effects of chemotherapy weresignificantly more common in older children, boys, and childrenwith leukemia. Vincristine was the most common culprit.

Background: Granulomatous skin lesions are characterized by aggregation of activated histiocytes. Granulomatous skin lesions are classified as xanthomatous, necrobiotic, tuberculoid, sarcoidal, and foreign body types. This study evaluates the clinicopathological features of patients with granulomatous skin lesions.Methods: We conducted a cross-sectional study of 232 skin biopsies diagnosed as granulomatous skin lesions over ten years from patients referred to Afzalipour Hospital, Kerman, Iran. Demographics, clinical features of lesions, and pathological characteristics were recorded. Then, the correlation of the final diagnosis with the demographic and clinical features of the patients was assessed via the independent t-test and chi-squared test.Results: Most patients were in their third decade of life, with a male-to-female ratio of 1.05 to 1. The most common types of granuloma were tuberculoid (60.3%), necrobiotic (12.5 %), and foreign body type (11.2%). Infectious disease was the most common cause of granulomatous lesions (64.2 %); leishmaniasis constituted approximately 96% of cases. The most common causes of noninfectious granulomatous skin diseases were foreign body granuloma (26.2%), granuloma annulare (23.2%), and xanthogranuloma (12.1%). There was a significant correlation between dermatologic disease type and disease duration (P = 0.024).Conclusion: In the current study, the most common type of granuloma was tuberculoid, followed by necrobiotic and foreign body type granulomas. Infectious diseases were the most common cause of granulomatous skin lesions. Furthermore, the most common granulomatous skin diseases were leishmaniasis, foreign body granuloma, and granuloma annulare. The least common granulomatous skin lesions were sporotrichosis and gout.

Background: Basal cell carcinoma (BCC) is the most common type of skin tumor. Surgical removal has remained the gold standard of treatment for BCC, but incomplete removal is an important clinical challenge. The goal of our study was to evaluate the incomplete excision of BCC and the factors affecting it.
Methods: In this retrospective study, 361 histological samples of BCC excisions referred to the Pathology Department of Imam Reza Hospital, Mashhad, Iran, from 2004 to 2018 were reviewed. Data including age, gender, tumor site, size, histopathologic subtype, surgical margin involvement, and the surgeon’s specialty were recorded.
Results: The incomplete removal rate was 20%. Ten percent of the lesions had deep margin involvement, 5.8% had lateral margin involvement, and both margins were involved in 4.2% of cases. Incomplete excision had a significant relationship with the following variables: nodular, mixed, and sclerosing types; the 60-70 years age group; lesions larger than 2 cm, location in nose and canthi; and excision by an otorhinolaryngologist, ophthalmologist, or dermatologist.
Conclusion: In this study, the frequency of incomplete excision was relatively high compared with other studies. Therefore, it is suggested to perform a diagnostic biopsy before the complete excision of BCC. Excision with a wider margin or using Mohs surgery is recommended for midface lesions, older individuals, nodular, mixed, or sclerosing lesions, and for tumors larger than 2 cm.

Trichilemmal carcinoma is a rare tumor of the outer sheath cells of hair follicles. These tumors occur on the sun-exposed skin of the elderly in the majority of cases. The gross tumor demonstrates exophytic, polypoid, ulcerative, or nodular lesions with or without bleeding. Histopathologically, it is characterized by an anastomosing trabecular, diffuse, or lobular growth pattern with clear keratinization. A critical differential diagnosis is squamous cell carcinoma (SCC), where the prognosis of trichilemmal carcinoma is far better than SCC. Surgery is a significant and effective treatment for trichilemmal carcinoma cases, and recurrence after complete surgical resection with a negative margin is uncommon. Trichilemmal carcinoma is considered a low-grade tumor with low metastatic potential. This paper reports a 48-year-old Iranian male with trichilemmal carcinoma of the scalp treated with surgery, having no recurrence after three years of follow-up. The role of other treatment modalities like radiation, local therapy, and systemic therapy are also discussed.

Viral skin diseases range from simple superficial exanthems to complex systemic diseases, affecting people of all ages. Careful assessment of infectious contacts and immunization status is of considerable importance along with a thorough physical examination. Recent research has linked a deficiency of vitamin D to an increased risk of autoimmune, infectious, and atopic disorders. Intralesional vitamin D3 may be an effective treatment option for warts. Vitamin D3 derivatives are effective for various skin conditions, including psoriasis, transient acantholytic dermatosis, actinic porokeratosis, and keratosis palmaris et plantaris. Vitamin D3 treatment has been shown to decrease chemokine synthesis and monocyte trafficking, as well as to downregulate toll-like receptors (TLRs) 2 and 4 of monocytes. This suggests an association between TLRs and vitamin-D-mediated innate immunity. The effect of vitamin D derivatives was speculated to be derived from its potential to regulate epidermal cell proliferation and differentiation and to modulate cytokine production. According to some studies gathered here, not only we can use different forms of vitamin D as therapy for viral skin disease, but also there is an important relationship between them. Therefore, we should consider the serum level of vitamin D for better management of these disorders. Also, keeping vitamin D levels within the normal range may be a preventative healthcare strategy.

Background: Wound healing is one of the main problems faced by medical scientists. Nowadays, herbal compounds are used to accelerate the repairing process. Coumarin is a plant compound with anti-inflammatory and anti-oxidant effects. In the present study, the benefits of using coumarin in accelerating wound healing were investigated in mice.Methods: Sixty male BALB/c mice were used. After making a linear wound on the dorsum of the animals, they were randomly divided into five equal groups: the first and second groups received topical cream of coumarin at concentrations of 1% and 2%; the third and fourth groups received nitrofurazone cream (positive control) and eucerin cream (negative control), respectively. The fifth group as the sham group was not treated. Then on days 4, 7, 10, and 14 of experiment, biopsies were performed on three mice from each group. Histological examination was performedusing hematoxylin and eosin and Masson trichrome staining. Data were analyzed by ANOVA and Tukey tests.Results: Inflammation significantly decreased in both experimental groups at days 4, 7, and 10, compared to the control groups. In the proliferation phase, fibroblast cells, granulation tissue formation, and epithelialization were significantly higher in both experimental groups than the control groups. In addition, collagen synthesis significantly increased in the experimental groups compared to the control groups.Conclusion: Topical application of coumarin had beneficial effects on different phases of wound healing in the skin of BALB/c mice.

Background: Psoriasis is a chronic immune-mediated skin diseasewith a genetic predisposition. Prolactin may contribute to psoriasispathogenesis. However, there has been a debate over the serumlevel of prolactin in psoriatic patients. The aim of this study was todescribe the role of serum prolactin in the pathogenesis of psoriasisMethod: The serum prolactin level was measured in 45 patientswith psoriasis and in 45 sex- and age-matched healthy individualsusing radioimmunoassay.Result: The mean serum prolactin concentration was not differentbetween psoriatic patients and healthy controls (320 ± 179.38 vs.318.18 ± 191.78 mIU/L, respectively P = 0.95). There was no sexandage-related differences in serum prolactin between the twostudy groups. Hyperprolactinemia (serum prolactin >324 mIU/Lin men, and >496 mIU/L for women) was observed in 11 patientswith psoriasis and 12 healthy subjects, which showed no significantdifference between the two groups (P = 0.81). The serum prolactinwas not significantly correlated with the duration of the disease(r = -0.18, P = 0.24) or the PASI score (r = 0.10, P = 0.50).Conclusion: The possible role of pituitary-produced circulatingprolactin in the disease process needs further investigations.

Methods: In this study, 1135 type-2 diabetic patients were included and examined by a dermatologist for diabetes mellitus related skin lesions, skin infections and cutaneous complications of the treatment. Smear, culture and biopsy of the lesions were done for definite diagnosis. Weight, height, blood pressure were also done. FBS and HbA1C were measured for all patients Results: The mean age of the study population was 54±11 years; 619 were (55%) female and 516 were (45%) male. Mean duration of the disease was 9±7 years and HbA1c was 7.8±1.6. The prevalence of skin lesions was 64% (95%CI: 61.2-66.8). The most common solitary skin lesion was diabetic dermopathy (32.3%) while the most common condition observed overall was skin infections (41.5%). Acanthosis nigricans with a prevalence of 26.4% was the third most common lesion. Other skin conditions had a prevalence of less than 12%. Skin disorders were apparently more prevalent in male than in female patients.Conclusion: More than sixty percent of patients with type-2 diabetes mellitus have skin lesions.

Background and aim: Low-power lasers relief pain in some musculoskeletal disorders and accelerate wound healing process. However, there are few reports on effects of low-power lasers on mast cells. In this study the effects of low-power gallium aluminium arsenide laser (Ga.Al.As.laser) radiation on number and degranulation of mast cells of open skin wound bed of rats were studied using quantitative histological methods.Materials and Methods: Forty-six male rats were randomly divided into experimental and control groups. Each group divided into 3 subgroups based on duration of study: 4 , 7 and 15 days. Under general anesthesia and sterile conditions one circular full thickness skin wound was made on the doesum of neck of each rat. The wounding day was considered as the day zero. From the day one, experimental rats received Ga. Al. Ar. laser radiation at a energy density of 1.2 J/cm2. After doing daily treatments, on days 4, 7 and 15, rats were killed by ether and samples were obtained from wound bed and normal adjacent skin from each rat. Samples were fixed in formalin saline and were prepared for routine histological study. Sections were stained by 0.1% watery solution of toluidine blue and total number of mast cells and their grades (one, two and three) were counted. In grade one, mast cell is intact, in grade two some granules have been extruded from the cell and in the mast cells of grade 3, degranultion is more extensive and widespread. Data were analysed by Student t test.Results: On the day 4, total number and grade one mast cells were significantly higher in the control group (P<0.01). On days 7 and 15, total number of mast cells and their grades were higher in the experimental group. The grade 2 mast cells on day 7 and grade 1 mast cells on day 15 of experimental group was significantly higher than control group (P<0.05).Conclusion: Low-power gallium aluminium arsenide laser irradiation on open skin wound of rats reduced significantly total number of mast cells and intact ones at inflammatory phase, and 90 significantly increased active mast cells at proliferation, and intact ones at remodeling phases of the wound healing process.

Since the discovery of X-rays, the use of imaging technology has continued to play an important role in medicine. Technological advancements have led to the development of various imaging modalities, most of which have been used to image organs deep within the human body. More recently, attention has focused on the application of imaging technology for evaluation of the skin. A variety of techniques are currently being used to examine the skin and these include specialized photography, surface microscopy, ultrasound, laser Doppler perfusion imaging, confocal microscopy, magnetic resonance imaging and optical coherence tumography. These modalities can provide information hat can assist in the management of skin problems. Although many of these techniques are still undergoing research, they are showing promise as useful clinical tools in dermatology. In this review article we discuss about each of these technologies in brief.

Background: Due to infections, cardio-vascular involvement and renal insufficiency, patients with systemic lupus erythematosus live shorter than usual. Objective: To determine the mean survival rate of SLE patients. Patients and Methods: 62 SLE patients admitted in the hospitals of Kerman University of Medical Sciences from 1369 to 1380 were included in this study. The demographic variables, which were effective on disease survival time, evaluated. Results: Mean survival time, regardless of other descriptive variables, was 9.2±0.89 years. The cases who had skin lesions first, in comparison with those who had rheumatic signs at first, revealed lower survival rate and more morbidity. The mean survival rate of cases who received combination of corticosteroid and anti-malarial drugs, corticosteroid drugs alone, and cyclophosphamide plus anticoagulants, were 12.0, 9.5 and 8.5 years, respectively. Conclusion: The prognosis in SLE patients with early skin manifestations was poorer than those with early rheumatic presentation. Best prognosis was noted in patients who received systemic steroids in comparison to other treatment modalities.

Background: Squamous cell carcinoma has a wide range of histological differentiation, which indicates the prognosis. Location of the tumor also affects its prognosis. Objective: To determine the relationship between location of the tumor, age and sex of patients and histological grading of it. Patients and Methods: In this retrospective study, 44631 files of the patients who were referred to two main pathological centers in Kerman from 1992 to 1999 were reviewed, and the data of 186 cases of skin squamous cell carcinoma were extracted and analyzed. Results: In 186 cases of skin squamous cell carcinoma, the mean age of patients was 60.4±16.6 years. 133 patients (70.9%) were male and 53 cases (29.1%) were female, so male to female ratio was 2.5 to 1. The most common sites of involvement were head and neck (76.8%), upper extremities (10.2%), trunk and genitalia (6.8%) and lower extremities (6.2%). 81.5% of tumors were well differentiated, 14.3% were moderately and 4.2% were poorly differentiated. There was no relationship between age, sex and site of the lesion with grading of the tumor. Conclusion: In order to manage squamous cell carcinoma properly, performing biopsy in all cases is mandatory.
