[Angiomyofibroblastoma of the male genital tract. Pathological and immunohistochemical study of three cases]. / L'angiomyofibroblastome du tractus génital masculin. Etude anatomo-clinique et immunohistochimique de trois cas.

Angiomyofibroblastoma of the male genital tract is a rare tumor with only 20 cases reported in the literature to date. We report three cases in males aged from 23 to 44 years. They presented with painless inguinal, scrotal and perineal masses, ranging from 3 to 8 cm in diameter. On microscopic examination the tumors were composed of small spindle cells without atypia in a fibrous and myxoid stroma. There were scattered mononuclear inflammatory cells around capillaries. Immunohistochemical studies showed positive staining of the tumor cells for vimentin, and weak reactivity for CD34, bcl-2, CD99, EMA and CD117. Some tumor cells expressed estrogen receptors in all three cases, and progesterone receptors in only one case. There was no recurrence with a follow-up ranging form 12 to 21 months. Angiomyofibroblastoma of the male genital tract is a benign often hormone-dependent tumor. Its histogenesis is still unclear. It has to be distinguished from aggressive angiomyxoma and myxofibrosarcoma.

Is routine pathologic evaluation of hemorrhoidectomy specimens necessary?

AIM: To confirm that systematic histological study of hemorrhoidectomy specimens is useless, as is proposed by the French Society of Coloproctology (Société Nationale Française de Colo-Proctologie) under the sponsorship of the French National Health Accreditation and Evaluation Agency (Agence Nationale d'Accréditation et d'Evaluation en Santé). METHODS: Retrospective histological analysis of hemorrhoidectomy specimens obtained in a coloproctology unit between January 1, 1985 and December 31, 2001. RESULTS: We found 56 histological abnormalities (0.69%) among 8153 hemorrhoidectomy specimens considered normal at gross examination, with three cases of intraepithelial neoplasia of the anal canal (0.04%) and four cases of severe dysplasia (0.05%). Specimens associated with anal fissure (N = 906) or suppuration (N = 610) did not display more histological lesions. For all patients, the initial surgical resection prevented recurrence. CONCLUSION: Routine pathological evaluation of hemorrhoidectomy specimens is not useful and is expensive. All operating procedures in proctology should reflect this attitude. It is nevertheless advisable to select for gross and microscopic evaluation any suspicious areas noticed at the preoperative examination or during the procedure.
