[Intimal muscular fibrodysplasia responsible for an ischemic gastric ulcer in a patient with a von Recklinghausen's disease: a case report].

A 78 year-old woman, suffering from a von Recklinghausen's disease sought medical assistance for hematemesis with anemia. This patient had previously experienced an amputation of the right arm for gangrene. Gastric fibroscopy unveiled a deep chronic ulcus developed in the antrum, highly suspect of malignancy. Multiple biopsies of the ulcer showed mainly interstitial gastritis. The persistence of the hematemesis imposed a subtotal gastrectomy. Pathological examination of the operative specimen evidenced an ischemic ulcer caused by arterial intimal muscular fibrodysplasia with associated neurofibromatosis in the neighboring sub-mucosal layer. This case report highlights the frequent association of phacomatosis especially von Recklinghausen's disease, with vascular lesions whose clinical expression mainly depends on the involved vascular area.
