RESUMO
Abstract The Borst-Jadassohn phenomenon is a morphological finding that consists of the presence of well-defined nests of cells located in the spiny stratum of an acanthotic epidermis. One of the neoplasms where this phenomenon is found is hidroacanthoma simplex. This neoplasm is considered the intraepidermal form of the eccrine poroma. Despite its benign nature, malignant transformations are reported. The present article reports a case of hidroacanthoma simplex and discusses the dermoscopy of this phenomenon.

We report a case of trigeminal trophic syndrome (TTS) on the scalp of a 69-year-old woman. Initially, the diagnosis of pityriasis amiantacea was considered. The review of pathological antecedents and knowledge of TTS were fundamental for the diagnosis of this illness. We performed a brief review on TTS and differential diagnoses.
RESUMO
Acquired elastotic hemangioma is a hemangioma variant first described in 2002. It is characterized by being a benign, solitary, slow-growing lesion, that appears in adulthood and is associated with solar exposure. It is a rare hemangioma variant with few cases reported in the literature. We present a case of acquired elastotic hemangioma on the back of the right hand and forearm in a male adult. Acquired elastotic hemangioma is a benign vascular proliferation associated with solar exposure, usually assymptomatic. It affects adults between 59 and 65 years of age. Histopatologically it is characterized by proliferation of small vessels in the upper dermis that are disposed parallel to the epidermis, and significant solar elastosis. The treatment is surgical, with no relapses reported.
