[Leiomyosarcoma of the vagina: a rare case].

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.

[Spermatocytic seminoma. Apropos of a case and review of the literature].

We report a case of sperm cell seminoma caused by trauma. The data in the literature indicate the frequency is less than 5% of all seminomas. This case was exclusively located in the gonads and was a pure form.

[A rare cause of retroperitoneal fibrosis: actinomycosis].

The authors report a case of retroperitoneal fibrosis secondary to actinomycosis with consequences on the urinary tract. They insist on the difficulty of diagnostic, the antibiotic's sensibility and the evolution towards fibrosis which can lead to renal function deterioration.
