Morphologic patterns of testicular lesions in Uyo: A university hospital experience

RESUMO

Background: The testis can be biopsied either for a diagnostic or therapeutic purpose. Objective: The aim of this study is to characterize the common indications for testicular biopsy and determine the pattern of testicular lesions. Materials and Methods: This was an 8­year retrospective study of all testicular and paratesticular specimens that were histologically diagnosed in the Department of Histopathology in University of Uyo Teaching Hospital between January 2008 and December 2015. Results: Sixty­four cases of testicular specimens were received in the histopathology laboratory, accounting for 1.3% of all received specimens. The youngest patient was 4 years, while the oldest patient was 86 years with a mean age of 54.4 ± 21.62. The most common presenting complaints seen in the nonfertility, nonprostate cancer­related cases were testicular swelling, pain, and small­sized testis as seen in 50%, 31.3%,and 12.5% of cases, respectively. In 60.9% of cases, the clinical diagnosis was prostatic cancer, while primary and secondary infertility accounted for 12.5% and 1.6%, respectively, with testicular/paratesticular tumor been the clinical diagnosis in 7.8% of cases. The mean ages for surgical castration patients, male infertility patients, and malignant lesion patients were 68.9, 41.7, and 46.5 years,respectively. Hypospermatogenesis was the most common histopathologic diagnosis of testicular biopsies in infertile men (33.4%). Four malignant lesions were seen, with embryonal rhabdomyosarcoma accounting for 50% of cases. Conclusion: Benign neoplastic lesions of the testis are very rare in study population, while embryonal rhabdomyosarcoma is the most common malignant lesion seen. Most men do not present to health facility for infertility management
