Squamous cell carcinoma of the bladder presenting as vulvitis and cliteromegaly.

INTRODUCTION: Clitoral metastases are exceptionally rare. We present a case of a squamous cell carcinoma of the bladder presenting with a clitoral metastasis. CASE REPORT: We report the case of an 84-year-old lady with frequency, dysuria and a clitoral mass, which was found to be a poorly differentiated carcinoma on fine needle aspiration cytology. Cystoscopy revealed a moderate to poorly differentiated squamous cell carcinoma of the bladder. CONCLUSION: This is the first reported case of a squamous cell carcinoma of the bladder with clitoral metastasis. Clitoral metastases are exceptionally rare, with only seven previous cases reported in the literature. Although the commonest cause of cliteromegaly is hormonal, a metastatic carcinoma should be considered as part of the differential diagnosis in the elderly female.

Targeting of bladder cancer with monoclonal antibody NCRC48--a possible approach for intravesical therapy.

OBJECTIVE: To determine the localization of the anti-MUC1 mucin monoclonal antibody (mAb) NCRC48 to bladder cancer following intravesical administration. PATIENTS AND METHODS: mAb NCRC48 (330-500 micrograms) radiolabelled with 111indium (11-17 MBq) was administered intravesically to 12 unselected patients with radiological evidence of bladder cancer. Tumour localization was assessed by gamma-camera imaging and by tissue biodistribution studies on biopsies obtained at cystoscopy at about 2 or 24 h after the procedure. After 24 h, whole blood radioactivity was measured and 3 weeks after the procedure the serum level of human anti-mouse antibodies was estimated using an ELISA method. RESULTS: Eleven patients had tumours confirmed at cystoscopy (grades 1-3, stages pTa-pT2). The mean uptake of NCRC48 by tumour and by normal urothelium (expressed as the percentage of the instilled dose/g x 10(3) +/- SD) at 2 h was 3.42 +/- 3.68 and 0.41 +/- 0.77 (P < 0.05). After 24 h, the values for tumour and normal urothelium were 1.17 +/- 1.18 and 0.17 +/- 0.11, respectively. Areas of increased activity on the scintigrams were consistent with the position of the tumours at cystoscopy. No radioactivity was detected in blood at 24 h and there was no evidence of a human anti-mouse antibody response. CONCLUSION: The MUC1 mucin may be a suitable antigen to study the potential of therapeutic strategies based on monoclonal antibody targeting of superficial bladder cancer and may allow the development of more effective agents in the treatment of this condition.

Primary pneumococcal peritonitis.

Primary pneumococcal peritonitis is an uncommon condition which in the preantibiotic era was associated with a high mortality rate. We present two cases and discuss the aetiology, clinical features and management of this condition.
