[Erythema nodosum and Crohn's disease].

Erythema nodosum was found on 11 out of 106 patients with Crohn's disease (10.4%), being the most common skin complication after the perianal ones. Women were affected more often than men (2.7:1) and most of the patients were above 15 and below 40 years of age. Patients with ileocolic lesions were more often affected than those with lesions confined to the small bowel. No cases of erythema nodosum were found in association with granulomatous colitis, as opposed to other authors experience. The eruption was usually related to the periods of active inflammatory bowel disease but not to the administration of salazopyrine. The morphology and evolution of the lesions was typical of erythema nodosum and joint involvement was almost constant. The differential diagnosis with other nodular eruptions that can occur in association with Crohn's disease are discussed and hypothetical common etiopathogenic factors to both Crohn's disease and erythema nodosum are briefly considered. The relevant literature is reviewed and commented upon.

[Cutaneous angioleiomyomas. Review of 75 patients with 77 tumors].

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.

[Juxta occipital epithelioid sarcoma].

A 24 years old female patient with a juxta-occipital epitheloid sarcoma is reported. The lesion, a slow growing assymptomatic nodule, started 5 years ago reaching 4 cm in diamter. It was deep seated in the cervical muscles but easy to surgically remove. No evidence of metastases or local recurrence was detected for the next six months in spite of the limited excision performed. Clinical and histological features of the tumor were reviewed and its differential diagnosis discussed, particularly with synovial sarcoma and clear cell sarcoma of tendons and aponeuroses. Histogenetic hypothesis were briefly considered and the relevant literature was reviewed.
