Four cases of traumatic ureteral damage are presented. The etiology of ureteral injuries is gunshot wounds for one case and motor vehicle accidents for three cases. Need for a high index of suspicion and diagnostic measures with IUP is stressed. Prompt operative management is recommended. Conservative surgery is emphasized.
Epidermoid cyst of the testis is a benign tumour. It is not rare since between 1971 and 1980, 6 were found amongst 54 tumours of the testicule in the Rennes Regional Hospital Centre. The lesion is asymptomatic, causing neither lymphadenopathy nor any laboratory abnormalities. It can be differentiated from a malihgnant tumour only by histopathological examination and treatment may be summarised as orchidectomy.

"Fracture of the penis" by damage to the erectile structures is rare. This accident usually occurs when the erect penis is subjected to trauma, usually during intercourse. The diagnosis is easy in the presence of a haematoma spreading from the fraenulum to the scrotum, with sometimes an obvious breach in the albuginosa of one corpus cavernosum. In the three cases reported here, immediate surgery was possible in two. Early operation, with repair of the ruptured albuginosa, offers the best guarantee of cure without any disturbance in erection.

We report a case of urteroileal fistula in a young 22 year-old-man with Crohn's disease, who presented with microscopic hematuria and severe diarrhea. Excretory urogram and retrograde pyelography showed a fistula between the right ureter and the terminal ileum which was successfully managed with conservative approach using a double J ureteral stent.

With reference to two cases of epidermoid cyst of the testes, it is recalled that testicular tumors are rarely benign (3% of cases); among these the epidermoid cyst remains exceptional. This tumor is always benign, with no degenerative potential, as long as it exists in the pure form. Only the histological examination permits one to affirm that it is an isolated epidermoid cyst without any other teratomatous constituent. Simple orchidectomy is the treatment of choice for this tumor.
Carcinoma in situ, dysplasia, prostatic intra-epithelial neoplasia, duct-acinar dysplasia and large-acinar hyperplasia are various terms describing more or less identical forms of prostatic epithelial atypia. The precancerous nature of these lesions can be demonstrated by: morphological and functional similarities with carcinoma, a younger age than that of carcinoma, a higher incidence in cancerous prostates, an identical zonal distribution and a significant progression of high-grade lesions towards carcinoma. These hypoechoic lesions can be detected or monitored by transrectal ultrasonography. They also secrete PSA at levels intermediate between those of benign prostate and adenocarcinoma. Because of the occasional risk of malignant transformation and a frequent association with carcinoma, these lesions should be regularly monitored by digital rectal examination, PSA assays and possibly by ultrasound-guided biopsies.

The appearance of a leukemic infiltration of the prostate gland as the first manifestation of a chronic lymphocytic leukemia, followed by an adenocarcinoma of the prostate gland, is exceptional, since only one case has been previously documented. For this reason the authors wish to signal the possibility of a prostatic infiltration in the course of chronic lymphocytic leukemia and insist on the association of this type of leukemia and cancer.
