title: Carcinoma of the bladder presenting as gonococcal cystitis.
abstract: A patient with gonococcal infection presented with frank haematuria. On subsequent investigation a transitional cell carcinoma was found. Because the haematuria resolved rapidly after treatment with ampicillin no sinister cause for the bleeding was suspected. Since gonorrhoea is rarely associated with gross haematuria, when it does occur a thorough investigation should be undertaken.
