CME Credits: 1.00
Released: 2024-02-07
A man in his 40s presented with a 10-year history of pruritic lesions on the scrotum and buttock. He was diagnosed with eczema and treated at the local clinic with little improvement. He had no relevant medical history and no family history of similar skin problems.
Physical examination revealed scattered, well-defined, annular gray hyperkeratotic plaques with an atrophic center and a slightly elevated edge on the scrotum, buttock, groin, and intergluteal cleft (Figure 1A). There was no inguinal adenopathy, and results of routine blood work, including blood biochemistry, syphilis serologies, and HIV testing, were normal or negative. We took 2 specimens from the scrotum and buttock, respectively, for histopathological examination (Figure 1B).
