RESUMO
Reactive perforating collagenosis (RPC) is a rare form of transepithelial elimination, in which genetically altered collagen is extruded through the epidermis. Of the acquired and inherited form, inherited form is extremely rare. Here, we present two cases of inherited form of RPC in a family.
RESUMO
Type 2 lepra reaction or erythema nodosum leprosum (ENL) is an immune complex syndrome that occurs mostly in lepromatous leprosy and sometimes in borderline lepromatous leprosy patients. We present an untreated case of lepromatous leprosy, who presented with type 2 lepra reaction and livedo reticularis. Livedo reticularis, though seen in lucio phenomenon, is not a part of type 2 lepra reaction. The case is being reported for its rarity.
RESUMO
Epidermolysis bullosa (EB) pruriginosa is a very rare pattern of dystrophic EB caused by type VII collagen gene mutation, with distinctive clinico-pathological features. It is characterized by nodular prurigo-like lichenified lesions, nail dystrophy, and variable presence of albopapuloid lesions. We report two such cases.
RESUMO
BACKGROUND: Dermatoscopy is a new noninvasive tool for the diagnosis of various skin and hair disorders. Dermatoscopy of alopecia areata (AA) shows various specific features, which may aid in confirming the diagnosis. AIMS: The aim of this study was to determine the various clinical patterns and the dermatoscopic features of AA. MATERIALS AND METHODS: A total of 75 patients of AA were evaluated with a dermatoscope (magnification ×25 and ×60). RESULTS: The mean age of onset of AA was 23.58 years. Males were more commonly affected. Scalp was most commonly involved. Patchy alopecia was the most common pattern observed. 10 patients showed concomitant nail changes. The dermatoscopic features included yellow dots (YDs) in 43 (57.33%) patients, black dots (BDs) in 63 (84%) cases, broken hairs (BHs) in 28 (37.33%) cases, short vellus hair (SVH) in 51 (68%) patients and tapering hair (TH) in 14 (18.67%) cases. CONCLUSION: The most common dermatoscopic finding observed was BDs, followed by SVHs, YDs, BH and TH.
