ABSTRACT
Abstract: Pigmented purpuric dermatoses are chronic vascular inflammatory conditions characterized by the presence of pigmented macules. Among its different presentations, lichen aureus is distinguished by the lichenoid conformation of its plaques and the predilection for lower limb involvement. Its segmented form is rare and difficult to control, especially in cases of symptomatic lesions. We report a rare case of segmental lichen aureus with six years of evolution associated with light itching. We also discuss the main therapeutic approaches to control the disease.

Abstract: On rare occasions, skin lesions are the first local of metastatic manifestation of internal malignancies. In case of no previous diagnosis of these tumors, the approach of suspicious skin lesions becomes a challenge, especially in differentiating cutaneous metastases and adnexal primary neoplasms. Currently, besides epidemiologic, dermoscopic and histopathologic aspects, the evaluation also integrates immunohistochemical exams and cell markers such as p40 and p63, highly specific for skin metastases. This article describes the case of cutaneous metastases as the sole obvious sign of breast cancer in a previously asymptomatic woman. The diagnosis was made by the finding of neoplastic cells in the dermis and immunohistochemistry compatible with ductal carcinoma.

Abstract: The Henoch-Schönlein purpura is the vasculitis associated with deposits of immunoglobulin A in small vessels. Its association with cytoplasmic antineutrophil cytoplasmic antibodies is possible, but rare. This vasculitis is uncommon in adults and the main clinic manifestations are purpuric lesions in lower limbs with gastrointestinal symptoms and renal involvement. The present work describes a rare case of Henoch-Schönlein purpura in an adult with cytoplasmic antineutrophil cytoplasmic antibodies.

Abstract: Chromoblastomycosis is a chronic fungal infection of the epidermis, dermis and subcutaneous tissue, in which the most common etiologic agent in Brazil is Fonsecaea pedrosoi. In more advanced cases we found many difficulties in their treatment, and therefore, we report a case of extensive and severe chromoblastomycosis, with therapeutical failure of first choice treatments, but good response to voriconazole.

The granulomatosis with polyangiitis, initially known as Wegener's granulomatosis, is a small and medium vessels vasculitis. It's classic form presents a triad: necrotizing granuloma of respiratory tract, necrotizing cutaneous vasculitis and glomerulonephritis. This vasculitis has cytoplasmic antineutrophil antibodies as signal. This work illustrates a case, of multisystemic rare disease, in which the segment and treatment were considered satisfactory for symptoms remission.
