Efficacy and safety of penile biopsy in a GUM clinic setting.
The UK National Guidelines on Sexually Transmitted Infections recommend penile biopsy in patients with persistent balanitis and balanitis of uncertain aetiology. Many GUM clinics perform penile biopsy. However, few studies have looked at the usefulness and safety of penile biopsy in a GUM clinic setting. We assessed the spectrum of dermatological conditions seen in a penile dermatoses clinic and looked at the usefulness and safety of penile punch biopsy in a GUM clinic setting. We reviewed the case notes of patients who attended the penile dermatoses clinic at the GUM department, Royal Berkshire Hospital, Reading over a period of 18 months. A total of 87 patients were seen in the penile dermatoses clinic. Their ages ranged from 17 to 73 and 70 (80%) were uncircumcised. Twenty-four (28%) patients had biopsies and five (6%) declined. Forty-nine (56%) patients did not have a biopsy either because of a clinically apparent diagnosis (45) or lesions were close to the urethral meatus (4). Five were referred for circumcision and one was referred to a dermatologist. Three patients were lost to follow-up. Penile biopsy was performed to exclude malignancy in 17 (71%) cases and due to diagnostic uncertainty in seven (29%) cases. Histological diagnoses were consistent with initial clinical diagnoses in 17 (71%) cases. Four (17%) had minor complications following biopsy, two had wound dehiscence, one had bleeding and another had a wound infection. In conclusion, a wide spectrum of penile skin disorders were seen in the penile dermatoses clinic. The majority of patients had a clinically apparent diagnosis. The histological diagnosis was consistent with initial clinical diagnosis in most of the biopsied patients. The main indications for biopsy were to exclude malignancy and for diagnostic dilemma. Penile biopsy is a safe procedure with minimal complications.
