Phyllodes tumour of the labia minora

Abstract

A 33-year-old woman presented for a preoperative examination prior to an upcoming operative hysteroscopy. During the examination, a firm 1 cm mass in her right labia minora was noted. The mass was excised in the operating room without difficulty. Pathological examination revealed a benign phyllodes tumour of the vulva. Phyllodes tumours are uncommon fibroepithelial tumours primarily found in the breast although rarely may present as a vulvar lesion. Phyllodes tumours of the vulva are rarely reported in the literature, with only 17 previously reported cases. This case represents the first reported case of a phyllodes tumour occurring in the labia minora. While most of these tumours are benign, it is important to keep these and other rare tumours in the differential diagnosis of vulvar masses. Even with benign tumours, continued surveillance for recurrence should be performed.
