RESUMEN
Abstract Eccrine porocarcinoma (EPC) is a rare malignant skin tumor. The dermoscopy of invasive EPC reveals focal presence of whitish-pink, structureless areas surrounded by pinkish-white halos. In an eccrine poroma (EP), such areas present diffuse distribution in the "frog- eggs" pattern. We reported an EPC in situ that presents a transitional dermoscopy pattern between EP and invasive EPC. We found a diffuse distribution; whitish-pink, structureless areas surrounded by pinkish-white halos; a central exulceration and a polymorphic vascular pattern.

Abstract: Granuloma faciale is a rare, chronic dermatologic disorder, which mainly affects the face. Recently, dermoscopy has been demonstrated as an important ancillary tool on the clinical diagnosis of facial dermatoses. We report two cases of granuloma faciale with yellow areas on dermoscopy that was not yet described in the literature, corresponding to abundant hemosiderin on histopathological examination.

Abstract: Subcorneal pustular dermatosis is a rare pustular eruption which occurs mainly in middle-aged women and rarely during childhood. We report a case of a 15-year-old female with a 4-year history of pustular lesions on the proximal region of the upper limbs with subsequent impairment of the trunk. Physical examination revealed small pustules distributed on the trunk and proximal region of the limbs. Histopathology showed a subcorneal pustule and direct immunofluorescence for IgA, IgM, IgG and fibrinogen was negative, confirming the diagnosis of subcorneal pustular dermatosis. The patient was treated with dapsone with good clinical response after one month. Subcorneal pustular dermatosis is a rare condition and there are only isolated cases reported in the literature in pediatric patients. Thus, we discuss the main clinical aspects and treatment response of this condition during childhood.

Os autores apresentam imagens de duas formas clínicas mais frequentes da Donovanose, em ambos sexos. A donovanose é considerada uma doença sexualmente transmissível, endêmica nas regiões tropicais e semitropicais do globo. Apresentam também imagens de duas lâminas: uma da pesquisa direta (corpúsculos de Donovan, dentro de grandes células mononucleadas coradas de vermelho pelo Giemsa) e outra de achados histológicos típicos (formato de alfinete dentro do histiócito).
The authors present images of two of the most common clinical forms of granuloma inguinale (donovanosis) in males and females. Donovanosis is considered a sexually transmitted disease that is endemic in tropical and subtropical regions of the world. Two microscopic images are also shown, one of a direct smear (the presence of Donovan bodies within large mononuclear cells identified using Giemsa stain) and the other of typical histological findings (rod-shaped Donovan bodies within a mononuclear histiocyte).
