Abscess Angiofibroma of the Rectus Abdominis Muscle: About a Case at the Bouaké University Hospital

Abstract

Introduction : Angiofibroma is a rare benign vascular tumor, composed of blood vessels and fibrous tissue (connective) with different locations. Localization at the level of the abdominal wall is rare. According to the literature, it is one of the cutaneous connective tumors. The diagnosis is suggested by the clinic and medical imaging, and confirmed by the anatomical pathology of the room after surgical excision. We report an unprecedented case of angiofibroma complicated by an abscess of the left rectus abdominis muscle in a 60-year-old patient. Observation : A 60-year-old patient, G6P6, does not consume tobacco or alcohol, has no history of particular family cancer, and was admitted for painful left paraumbilical mass evolving for 3 months associated with fever. She would have done a traditional therapy based on scarification, without improvement of the signs. It was in the face of the persistence of the mass with the secondary appearance of a fever, that his relatives took him to the surgical emergency. The clinical examination noted a good general condition, a fever and a fluctuating left paraumbilical mass measuring 9 cm by 7 cm in diameter. The abdominal CT scan with and without injection of contrast agent performed in emergency found an abscessed mass of the left rectus abdominis muscle and concluded that there was an abscessed cystic lymphangioma of the abdominal wall. Clinical examination and CT scans led to the diagnosis of an abscessed cystic lymphangioma of the abdominal wall. We have indicated tumor excision. The emergency surgical treatment consisted of a flat with suction of 400 cc of pus mixed with necrotic tissue. The post-operative effects were simple. Anatomical pathological examination of the necrotic tissues concluded that an angiofibroma was present. Nine years later, the tumor has not recurred. Angiofibroma is a rare benign tumor, especially in its abdominal parietal location. Its evolution can be towards abscess.
