INTRODUCTION: Acquired hypertrichosis lanuginosa is a form of obligatorily paraneoplastic disease characterised by the recurrence of lanuga hair during adulthood. We report a case in which this hypertrichosis allowed diagnosis of gastric cancer.
OBSERVATION: A 51 year-old woman was seen for hypertrichosis present for 3 months. Clinical examination led to diagnosis of acquired hypertrichosis lanuginosa, which subsequently resulted in the discovery of gastric adenocarcinoma. Surgical excision of the tumour resulted in the disappearance of hypertrichosis with no recurrence during the ensuing 13 months.
DISCUSSION: Acquired hypertrichosis lanuginosa is rare, with only 50 or so cases reported in the literature since the condition was first described in 1865 by Turner. These cases confirm the obligatorily paraneoplastic nature of this particular dermatosis. Our finding is original since it is the first recorded case of association with gastric adenocarcinoma. It is also unique in terms of the strictly parallel development of acquired hypertrichosis lanuginosa and the tumour, with complete disappearance of the hypertrichosis in the weeks following surgical removal of the tumour, and in terms of prolonged survival (complete remission 17 months after the onset of symptoms). The mechanism responsible for acquired hypertrichosis lanuginosa is unknown. Two hypotheses have nevertheless been suggested: acquired hypertrichosis lanuginosa could be associated with secretion by the tumour of an as yet unidentified serum factor, or with a nutritional deficiency that may accompany this form of cancer.
