Parotid lipoma: a report of two cases.

Parotid lipoma is a rare non-epithelial tumour of the salivary gland. In this communication, we present two cases and highlight the physical findings that aid the diagnosis and review the literature.

Reduction mammoplasty for unilateral breast hypertrophy.

Three cases of unilateral hypertrophy of the female breast are presented and the various methods of their management highlighted. We advocate increased awareness of the condition and improved general surgical training to cope with it.

Ascarid granuloma presenting as pseudotumour.

Three patients with histologically confirmed ascarid granuloma who presented clinically with abdominal masses simulating abdominal tuberculosis or lymphoma are described. The clinical course of one patient was complicated by the formation of a spontaneous faecal fistula and perforation of the terminal ileum. In two cases there was rupture of the inflammatory pseudotumour through the anterior abdominal wall.

The retained urinary catheter.

Retention of urinary catheters is an increasing complication in our practice. We have reported 18 patients seen over a 6-month period during which 528 catheterizations were done, representing an incidence of 3.4%.

Schistosomiasis of the appendix.

The clinicopathological features of schistosomiasis of the appendix are discussed, based on the clinical presentation, operative findings and morphological changes in the specimens of patients seen in Ibadan between 1980 and 1989. Schistosoma haematobium was implicated as the causal agent of a granulomatous inflammatory reaction with eosinophilia and fibrosis. Intramuscular oviposition was associated with frank acute appendicitis, and serosal involvement resulted in peritoneal adhesions, with ileoileal intussusception in one patient.
