[Leiomyosarcoma of the vagina: a rare case]. / Le léiomyosarcome du vagin: une observation rare.

Vaginal leiomyosarcoma is unfrequent. We report on a case in a 50-year-old multipara patient who had presented a posterior vaginal swelling since 6 months. The tumor was discovered at the occasion of pains and non hemorragic discharge. The histological pattern of the tumor was well-differentiated spindle cell sarcoma with pleiomorphic areas. The immunohistochemistry confirmed the smooth myogenic differentiation. The treatment consisted of posterior pelvic exenteration extended to the vagina. The patient is alive and free of disease at 20 months of fellow-up.

[Giant pelvic epidermoid cyst: a rare observation]. / Le kyste épidermique géant pelvien: une observation rare.

Epidermoid cyst is a frequent benign tumor. It gives rise to destruction of adjoining tissues, chiefly in the skull. The pelvic epidermoid cyst is rare. We report the second case of giant pelvic epidermoid cyst with a 25-year-old girl. Ultrasound exploration and computed tomography evoked an ovarian origin. The surgery discovers an epidermoid cyst under the peritoneum. Ovaries and uterus were undamaged. We realized an evacuation of cyst, which contained lamellas of keratin. Histology allowed confirmation of diagnosis. The patient is always observed after 18 months.
