RESUMO
We present a 30-year-old woman with a solitary circumscribed neuroma (also known as palisaded encapsulated neuroma) diagnosed after surgical excision. We describe the histopathologic correlation and the dermoscopic features we found in this tumor, which have not been previously reported in the literature to our knowledge.

Elastosis perforans serpiginosa (EPS) is a rare skin disorder characterized by transepidermal elimination of abnormal elastic fibres. We present a new case of D-penicillamine (DPA)-induced EPS, and describe the clinical, dermoscopic, histopathological and direct immunofluorescence (DIF) findings. A 33-year-old woman receiving treatment with DPA presented with annular skin lesions. Digital dermoscopy of the lesions showed a central area of pink and yellowish discolouration with keratotic papules in the periphery, surrounded by a white halo, disposed in a way that resembled the islands of an archipelago. Other lesions showed a white to yellow central colouration and 'chrysalides' surrounding the keratotic plugs. Linear and granular deposits of IgG attached to the abnormal elastic fibres were seen with DIF. Dermoscopy can be helpful in the diagnosis of EPS. Moreover, DIF findings in skin biopsies of this case support the immune-mediated pathogenesis of EPS.

Patients with autoimmune disorders are predisposed to develop a second immunologic disease, frequently with systemic involvement. We present a patient who developed lesions of discoid lupus erythematosus (DLE) limited to the face, and, concurrently, a linear morphoea involving her right axilla. No criteria for systemic lupus erythematosus or systemic scleroderma were present in the patient. To our knowledge, no patients with concomitant DLE and linear morphoea, without systemic involvement, have been previously reported in the literature.
