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.

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.
