Late diagnosis of angioleiomyoma of the knee: a case report
Case report, 97 - 99Tag this article
Angioleiomyoma, also known as angiomyoma, vascular leiomyoma or dermal angioma is an infrequent benign tumour originating from smooth muscle cells of arterial or venous wall. The peak incidence is between the third and sixth decades of life; a female preponderance has been reported. Minor trauma, venous stasis, hamartomatous changes, arteriovenous malformations and hormonal imbalance especially of oestrogen have been proposed for the etiology of the tumor. Standard treatment includes marginal surgical excision of the tumor. Local recurrence or malignant degeneration after surgical excision is rare. The duration of symptoms prior to diagnosis ranges from weeks to few years. This article presents a patient with a slowly enlarging angioleiomyoma of the knee over a time period of 12 years. The clinicopathological features, diagnosis and treatment are discussed.
