RESUMEN
Dowling-Degos disease (DDD) is a rare autosomal dominant condition characterized by multiple, small, round pigmented macules usually arranged in reticular pattern, chiefly distributed in axillae and groins. Here we are reporting three atypical cases of DDD in a family. They had hypopigmented macules with typical features of DDD indicating generalized DDD. Histopathology confirmed the diagnosis. We present these three cases to stress the existence of generalized DDD phenotype in the Indian population.
RESUMEN
BACKGROUND: Lupus vulgaris is the most common form of cutaneous tuberculosis in adults. Lupus vulgaris is caused by hematogenous, lymphatic, or contiguous spread from elsewhere in the body. histologically it is charecterised by typical tubercles with or without caseation, surrounded by epitheloid histiocytes and multinucleate giant cells in the superficial epidermis with prominent peripheral lymphocytes. MATERIALS AND METHOD: All cases of clinically and histopathologicaly diagnosed lupus vulgaris over the previous five years were included in the study. RESULTS: Fourteen cases of lupus vulgaris cases reported during the study period with eaqual incidence among males and females. DISCUSSION: Plaque type of lupus vulgaris was the most common type. Histopathologically tubercular granulomas were seen in all cases as compared to other studies. CONCLUSION: Different patterns of lupus vulgaris are reported.
RESUMEN
Dyschromatosis universalis hereditaria is a rare genodermatosis characterized by hyper- and hypopigmented macules in a reticulate pattern. Here, we present a case of DUH with involvement of the palms.
RESUMEN
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.
RESUMEN
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.
RESUMEN
Pheohyphomycosis is a rare heterogeneous group of mycotic infections caused by dematiaceous (phaeoid) fungi affecting the skin, subcutaneous tissue, and central nervous system. Herein, we report a case of 29-year-old man with innocuous pustule over the right index finger. Examination revealed a subcutaneous swelling with pustules over the surface. Biopsy revealed phaeoid fungi, and diagnosis of subcutaneous pheohyphomycosis was made.
