We describe an 8-month-old boy with a tumor involving the right testicle and epididymis. Anatomical and pathological examination of this tumor revealed embryological tissue and melanin granules derived from the neural crest. This is an uncommon neoplasm, which is especially rare in the testicles. The patient was free of disease after 30 months.

Twenty-four patients with varicocele and 26 normal men were analysed according to the seminal ejaculate and testicular biopsy. Patients were divided into two groups based on the criteria of sperm normality and abnormality, respectively. Hypospermatogenesis with both normal and abnormal seminal fluid occurred in the varicocele patients, but no statistical differences could be established when compared with each other. We concluded that testicular biopsy is not useful in the evaluation of patients with varicocele.

Seven cases of anterior urethral stricture were studied. The diagnosis was made by exclusion of the inflammatory and traumatic causes. In three cases the stricture was located in the bulbar and in four cases in the penile urethra. The results obtained were good, with a follow-up of 5 to 50 months. Considerations are made about embryogenic, diagnostic, clinical picture and treatment. The verification of extensive lesions of the urethra determined the use of more complex surgical techniques of Johansen's urethroplasty devised for the treatment of this kind of pathology.
