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: We report a case of a 76-year-old patient with a history of recent weight loss and ulcerated umbilical nodular lesion. Initially, we considered the diagnostic hypothesis of Sister Mary Joseph's nodule. However, histopathological evaluation revealed that it was an ulcerated intradermal nevus. We perform a brief review of umbilical nodules.
