Smooth muscle tumours of the vulva in Jamaica.

Smooth muscle tumours of the vulva are uncommon and their behaviour is unpredictable. A 30-year retrospective analysis of the pathology files and patient records revealed 10 cases diagnosed at the University Hospital of the West Indies, Kingston, Jamaica, with one malignant and one recurrent tumour. Size, infiltrating margins and mitotic count are important parameters to determine prognosis. Although these tumours are of low malignancy, mitotic count may be mandatory in determining their potential for recurrence.
