Diffuse intratubular undifferentiated germ cell tumor in both testes of a male subject with a uterus and ipsilateral testicular dysgenesis

Perspectives in Pediatric Pathology, Chapter 5. Gonadal Dysgenesis

One of the most challenging areas in pediatric testicular pathology is the appropriate understanding and pathological diagnosis of disorders of sexual development (DSD), and in particular, the issue of gonadal dysgenesis. Here we present the main concepts necessary for their understanding and appropriate classification, with extensive genetic correlations.

Testicular biopsy. Contemporary interpretation

Biopsy of the testis is not universally accepted in contrast with biopsies of other organs. The pathologist studies and reports on the pathophysiology of the testicular biopsy specimen. Methodology requires the inclusion of qualitative and quantitative studies, the evaluation of the lesion's evolution (prognosis), and, often, therapeutic advice regarding treatment. Cooperation between pathologists and clinicians optimizes the utility of the biopsy for the patient.

Torsion of intrascrotal malignant testis tumors

We report 2 cases of torsion of scrotal malignant tumors of the testis. A review of the literature disclosed several instances of torsion of intra-abdominal testicles with malignant tumors and only 1 case of a scrotal testis. The association of torsion and tumor in these cases may represent 2 manifestations of a dysplastic gonad.
