Endometriosis is a common dermatosis that most typically affects the pelvic organs. Extra-pelvic occurrences are reported in the literature. Umbilical endometriosis is rare and can be primary (spontaneous) or secondary (after surgery). The present study describes the case of a female patient with endometriosis lesions in the umbilical region, confirmed by histology. Treatment was carried out with wide surgical excision. It is important to note that differential diagnosis should be considered in the presence of umbilical tumors in women of reproductive age.

Temporal triangular alopecia (TTA) is a rare condition frequently mistaken for androgenetic alopecia or other hair disorders. We comment on the recent case reported by Lucca et al., emphasizing the importance of histopathological confirmation in suspected cases to avoid misdiagnosis and unnecessary treatments. Although valuable, trichoscopy may not reliably distinguish TTA from conditions such as alopecia areata, trichotillomania, or frontal fibrosing alopecia in advanced stages. Surgical correction remains the treatment of choice for confirmed TTA, but caution is warranted when considering hair transplantation in other forms of alopecia, as outcomes and safety may be compromised in the absence of diagnostic certainty.
