| Abstract: | Seventy seven angioleiomyomata from 75 patients, 19 males and 55 females, are reviewed. One patient had 2 lesions and another a local recurrence after surgical excision. Only 3 were less than 20 years old and most were beyond 30 (average age 47). Fifty four lesions were on the lower limbs, 4 on the head and legs), 9 on the upper limbs, 4 on the head and 1 on the trunk. The size of the lesions varied from a pepper grain to a pigeon egg but most were pea sized. The more significant symptom was pain, present in at least 58% of the lesions, and responsible for the diagnosis, often made, of neurofibroma, neuroma, glomus tumour and leiomyoma. Its intensity was variable and could be induced by mechanical or thermal stimuli or even arise spontaneously. Histologically the tumour was usually a deep dermal or hypodermal, well defined, ovoid or round shaped, compact nodule, composed of smooth muscle fibers often disposed around variously shaped vascular lumina. Clinical and histological similarities to glomus tumours as well as the occasional coexistence of both lesions point to a common origin from the myoarterial glomus or from a closely related arteriovenous anastomosis. The relevant features in our series are compared with those reported in the literature and their similarities and differences are discussed. |
