Clinical and Penile Dermoscopy Evaluation of a Reticulated Pattern on the Penile Glans.

A 32-year-old man visited our clinic for evaluation of a mildly pruritic lesion on the glans. He complained of a recurrent red patch, which had been slowly enlarging over the previous three months. Clinical examination revealed a slightly raised plaque with a reticulated lacy net pattern and white threads on the glans. There was no evidence of skin, nail or other mucosal involvement on physical examination. Laboratory tests, including hepatitis and syphilis serologies, were normal or negative. Penile dermoscopy revealed white reticular and circular lines [Wickham striae] on a red background. Penile dermoscopy should be included as a part of the clinical inspection of genital diseases to support diagnosis, as well as to ideally avoid unnecessary invasive investigation.
