Multiple acroangiodermatitis of the left big toe: A case report from the university clinic of dermatology-venereology of the national university hospital center Hubert Koutoukou MAGA of Cotonou in Benin

Abstract

Angioacrodermatitis, or Pseudo-Kaposi sarcoma, is a vascular anomaly observed at the extremities in patients with venous insufficiency, often triggered by trauma. Acroangiodermatitis may resemble Kaposi's sarcoma, but unlike Kaposi's sarcoma, acroangiodermatitis is not characterized by progressive changes, and there is a lack of spindle cells and vessels resembling slits on histopathological analysis. Thus, in clinical practice, it is important to recognize acroangiodermatitis and exclude Kaposi's sarcoma, as there may sometimes be similarity with this entity. Topical treatment with neutral corticosteroid preparations and local is often helpful. 35-year-old patient, a communications advisor, who consulted for asymptomatic solid lesions on the left big toe, evolving continuously for 10 years, progressively increasing in size. A toe injury preceded the onset of the lesions. He had no other medical history. On examination, there were angioma-like masses, firm with a discretely keratotic surface, welldefined, painless on palpation adherent to deep and superficial planes, of variable shape, numbering four (4), measuring 2 cm x 4 cm, the largest of which had a parrot beak appearance. There was a discreet increase in local temperature, but no bruit or thrill was noted. The HIV retroviral serology and blood glucose levels were normal. Histopathology revealed vascular proliferation with dilated luminal vessels separated by fibrosis. The diagnosis of acroangiodermatitis or pseudo-Kaposi sarcoma was made. Acroangiodermatitis is a vascular pathology that presents a differential diagnostic challenge with Kaposi's disease. Histopathology is the cornerstone of diagnosis.
