An unusual presentation of anetoderma: a case report

BACKGROUND: Anetoderma is a benign condition with focal loss of dermal elastic tissue resulting in localized areas of flaccid or herniated saclike skin. Currently, anetoderma is classified as either primary (idiopathic), or secondary anetoderma (which is associated with a variety of skin conditions, penicillamine use, or neonatal prematurity). Lesions appear on the upper arms, trunk, and thighs. CASE PRESENTATION: We report a 14-year-old boy, which was noticed to have had multiple, white, non-pruritic areas on the acral sites of upper and lower extremities for two years. In physical examination, the patient had normal mental development. Skin lesions consisted of scattered, white to skin-colored papules, less than 1 cm in diameter, and with central protrusion, with distribution on dorsal part of the index finger, forearms, distal portion of thighs and calves. Lesions were detected neither on the trunk nor the proximal areas of extremities. There are no sensory changes associated with the lesions. Otherwise, his general health was good. He did not have any medication consumption history. Family history was negative. Laboratory examinations were within normal limits. Skin biopsy from one of his lesions was done, that confirmed the diagnosis of anetoderma. CONCLUSIONS: In summary, we report a case of anetoderma on unusual sites of the skin. We could not find similar reports of anetoderma developing on distal extremities without involvement of the upper trunk and proximal arms, in the medical literature

Nasal cytobrush cytology: evaluation of the hyperchromatic supranuclear stria

To evaluate the hyperchromatic supranuclear stria (SNS) in various types of rhinopathies. Study Design The study included 42 patients with rhinopathies and a control group consisting of 28 healthy adults. The rhinopathy group was categorized into 4 subgroups, including allergic rhinitis, infective rhinitis, vasomotor rhinitis and mixed group. Cytologic samples were obtained by cytobrush from the middle one third of the inferior turbinate. Results The hyperchromatic SNS was present in the majority of ciliated cells in a high percentage in the control group (91.7%), whereas in the pathologic group it was 40%. The difference is significant (p=3D0.0000). Conclusion Nasal cytology is a simple, reliable tool for the diagnosis of rhinopathies

Presentation of AIDS with Disseminated Cutaneous and Visceral Leishmaniasis in Iran

Leishmaniasis is an infectious disease in form of visceral (VL), cutaneous (CL), and mucocutaneous (MCL) leishmaniasis. Immunocompromised patients have increased risk of Leishmania infection, especially in endemic areas for visceral leishmaniasis, where in the world HIV/VL coinfection has become endemic. The case here suffers from both AIDS and visceral-cutaneous leishmaniasis. We report an Iranian woman with disseminated cutaneous and visceral leishmaniasis who became positive for HIV test

Clinicopathologic evaluation of granuloma annulare: Study of 136 Iranian cases, south of Iran

Abstract Background and Objectives Granuloma annulare (GA) is a benign skin disorder with various histopathologic features that are rarely investigated in Iranian population. We performed this study to find out the clinical and histopathologic features of GA in our referral centre. Methods One hundred‐thirty‐six patients with biopsy‐proven GA were reviewed. Clinical data and pathological features were recorded. Results One hundred‐eight female patients and 28 male patients (Female/male ratio: 3.85) with mean age of 42.54 ± 21.2 years (range: 2–83 years) were recruited. Eighty‐eight (64.7%) patients had interstitial infiltrative pattern and 48 (35.3%) patients had complete palisading granulomas. The infiltrate occupied both upper and lower dermis in most of the cases (67.7%). Significant mucin was detected more commonly in complete GA compared to interstitial GA (p = 0.019), but inflammation degree, eosinophils, plasma cells, and giant cells were not different between two subtypes of GA (p > 0.05). The significant inflammation contained more significant plasma cells (p = 0.006). The significantly more giant cells were detected in patients between 20 and 60 years of age (p = 0.015); but other factors were not different between age groups. Conclusions In our study, the prevalence of GA in women was significantly higher than in men. Interstitial GA was the more common histological subtype and the inflammation was less severe and the infiltrate was mostly pandermal in our cases. More severe inflammation contained more plasma cells, and more dense giant cells were seen in middle aged patients

Crusted scabies masquerading as psoriasis plaques in a patient suffering from burn scars

A 30-year-old woman, presented with erythematous scaling plaques on her trunk with severe pruritus and a burning sensation that began 3 months prior to her visit. She had a history of a thermal burn in that area, three years prior. Topical corticosteroid application for 3 months had no positive effects. Skin biopsy was done and scabies mites were found

Value of CD10 Expression in Differentiating Cutaneous Basal from Squamous Cell Carcinomas and Basal Cell Carcinoma from Trichoepithelioma

Background: In addition to the well-defined histological criteria for squamous cell carcinoma (SCC) and basal cell carcinoma (BCC), immunohistochemical techniques can be used in difficult cases for their differentiation. As differential diagnosis between trichoepithelioma (TE) and BCC is sometimes difficult for the clinician and the pathologist, CD10 may be a useful marker for definite diagnosis. We aimed to evaluate the usefulness of this marker in the differentiation between SCC and BCC and also in the differentiation between BCC and TE.Methods: Fifty-five BCC cases, 50 SCC cases, and 20 cases of benign adnexal tumor with follicular differentiation were retrieved from the archives of the pathology departments of hospitals affiliated with Shiraz University of Medical Sciences. Immunohistochemistry for CD10 was performed on the sections obtained from formalin-fixed, paraffin-embedded blocks. CD10 immunoreactivity in the stroma and/or tumor cells was determined as follows: negative (0); 1+(10-50% positive cells); and 2+(>50% positive cells). Results: Comparison of CD10 expression between the BCC and SCC groups showed a significant difference (P<0.001) in each of the tumor and stromal cells. Comparison of CD10 expression between the BCC and TE groups demonstrated a significant difference in both the tumor and stromal cells (P<0.001). There was no significant difference in CD10 expression between the stromal and tumor cells of the BCC subtypes.Conclusion: CD10 is a useful adjunct marker in distinguishing TE from BCC. CD10 is suggested to be one of the useful immunohistochemical markers to differentiate BCC from SCC

Autoimmune progesterone dermatitis presenting as fixed drug eruption: a case report

Autoimmune progesterone dermatitis (APD) is a rare disorder characterized by periodic skin lesions that erupt during the luteal phase of the menstrual cycle. Clinical manifestations of APD is caused by an unusual allergy to progesterone and has a wide range of clinical manifestations from eczema and urticaria to angioedema and erythema multiforme. A 46-year-old woman described recurrent, round erythematous plaques on the lower lip, both forearms and buttocks. These skin eruptions waxed and waned for 10 months, reoccurring 3-4 days before menstruation. Based on her medical history and physical examination, APD was suspected and the progesterone challenge test showed positive results. After treatment with oral prednisolone (30 mg/day) before menstruation, the severity of eruptions decreased dramatically but recurrence did not cease completely

Analysis of Surgically Treated Cutaneous Malignancies in a Tertiary Dermatology Center During a Six-Year Period

Background: Cutaneous malignancies are common in dermatologic practice. Due to their relation to sun exposure the characteristics of these malignancies can differ in various geographic locations. This study intends to determine the characteristics of surgically treated cutaneous malignancies and various surgical modalities that have been applied. Methods: This was a retrospective study of patients with cutaneous malignancies who underwent surgery over a six-year period. Data regarding the general information, type of malignancy, location, surgical margin involvement and specific surgical modalities were recorded and analyzed. Results:A total of 432 patients were included. Basal cell carcinoma was the most common malignancy (82.8%) followed by squamous cell carcinoma (13.4%). Lentigo maligna, keratoacanthoma, basosquamous carcinoma, sebaceous carcinoma and Bowen’s disease accounted for the minority of cases. Patients' mean age was 65.7 years and the most common location was the nose and cheeks. The mean diameter was 2.97 cm. Excision was performed with safe margins. Incomplete excision was seen in 14% of basal cell and 15% of squamous cell carcinoma cases. The most common type of defect closure was a simple closure (43.9%). Conclusion: Basal cell carcinoma is the most common type of cutaneous malignancy. Surgery yields a satisfactory response as treatment for this cutaneous malignancy
