Condyloma acuminata on the nipple and coronary sulcus of the penis

Rationale Condyloma acuminatum (CA) is a benign tumor primarily caused by infection with human papillomavirus (HPV) type-6 or type-11, lesions of which are most frequently found on the genital and perianal squamous mucosa and skin. CA outside the genitals is not common. Patient concerns A 29-year-old male presented with lesions on the left nipple and coronary sulcus after heterosexual contact. Diagnoses Histopathological examination and HPV detection made a definite diagnosis of CA. Intervention The patient was treated with microwave and topical imiquimod cream. Outcomes After 6 months follow-up, there was no sign of recurrence. Lessons This case shows that we should pay more attention to CA outside the genitals in the process of diagnosis and treatment.
