Differential Diagnosis

	Key History	Clinical appearance	Biopsy
Candida		Erythematous rash with soreness and/or itch, blotchy erythema with small papules which may be eroded, or dry dull red areas with a glazed appearance
Anaerobic Infection		Foul smelling sub-preputial inflammation and discharg: in severe cases associated with swelling and inflamed inguinal lymph nodes Preputial edema, superficial erosions: milder forms also occur
Aerobic Infection		Variable inflammatory changes including uniform erythema and edema
Trichomonas vaginalis		Superficial erosive balanitis which may lead to phimosis
Treponema paliidum		Multiple circinate lesions which erode to cause irregular ulcers have been described in the late primary or early secondary stage. A primary chancre may also be present
Herpes simplex		Grouped vesicles on erythematous base over glans, prepuce and shaft which rupture to form shallow erosins. In rare cases primary herpes can cause a necrotic balanitis, with necrotic areas on the glans accompained by vesicles elsewhere and associated with headache and malaise.
