Reticulate pigmented anomaly of the flexures is a benign, recently described genodermatosis reported to involve the flexural areas as well as the scrotum. Described herein is a twenty-nine year old man in whom the characteristic speckled macules were limited to the scrotal and penile skin. The authors suggest that the anomaly be designated reticulate pigmented anomaly without reference to specific anatomic sites. It is possible that this pigmented eruption of the genitalia is a cutaneous marker of this patient's underlying testicular carcinoma.
