Adrenal hemangioma is an extremely rare benign and non-functioning neoplasm of the adrenal gland. We report a case of a 71-year-old woman admitted for intermittent abdominal pain and abdominal distension associated with vomiting and chronic constipation for 5 years. Physical examination revealed a large abdominal mass. Both computed tomography scan and magnetic resonance imaging suggested hemangioma in the right lobe of the liver. Laboratory examinations and tumour markers were within normal limits, except for hypochromic microcytic anemia. The mass was removed intact by conventional surgery and histopathology revealed a cavernous hemangioma of the adrenal gland with no signs of malignancy. Surgical resection was curative, with no recurrence at the 2-year follow-up.

BackgroundNeurofibroma is a rare benign tumor. The isolated presence of such lesions in the preperitoneal space with no evidence of systemic disease has never been reported in the literature.Case presentationA 29-year-old white man presented with a 12 months history of progressive abdominal distension. Clinical examination revealed a bulky hypogastric mass. Abdominal computed tomography and pelvic magnetic resonance imaging showed a large, well defined preperitoneal tumor measuring 18 x 17cm extending in the pelvis. A computed tomography guided biopsy was performed which revealed a neurofibroma. Exploratory laparotomy showed a well encapsulated elastic soft tumor in the preperitoneal space which measured 17 x 18cm and weighted 2 Kg. The tumor was completely excised. No recurrence occurred after one year of follow-up.ConclusionSolitary preperitoneal neurofibroma is an extremely rare benign tumor. Its clinical and radiological signs are nonspecific. Preoperative histology can be useful to guide the surgical approach which is the only curative treatment.

La tumeur de Buschke-Lowenstein est une affection rare appartenant au groupe des carcinomes verruqueux. Elle survient le plus souvent chez des sujets pubères en pleine activité sexuelle. Une infection par human papillomavirus (HPV) 6 et 11 est volontiers associée à ces tumeurs. Elle se caractérise par la fréquence des récidives et le risque de transformation maligne. Son traitement est difficile même si l'histologie confirme la bénignité. A partir de 16 observations de TBL et d'une revue de la littérature, les auteurs soulignent les aspects épidémiologiques, cliniques, thérapeutiques et évolutifs de cette affection.
