A Rare Case of a Symptomatic Tumor Found in the Groin Area: An Atypical Location Unexposed to the Known Causes.

Nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin syndrome, is a rare hereditary condition characterized by a wide range of developmental abnormalities and a predisposition to neoplasms. The syndrome consists of early-onset and/or multiple BCC. Herein we report a rare NBCCS case in which the first BCC onset occurred in the groin area. To the best of our knowledge, there have been no reports of first-onset BCC in the groin area in an NBCCS patient of any race.
