Clinico-Pathologic studies on Testicular and Peritesticular tumors
ABSTRACT
The incidence of testis and their adnexal tumor is rare, but testicular tumors constitute the fourth most common cause of death from neoplasia in the age group of 15-34 years of age. No organs, except ovary, have so various type of neoplasia than testis that there is no reliable classification of testicular tumors recently, and the urologist must depend on the clinical stage and on histologic appearance of the tumor. Even Pathologists confuse the classification and characteristics of tumor because their limited experience, variable morphologic features and nomenclature of tumor. The authors collected thirty cases of testis and their adnexal tumors in the Pathology Department of National Medical Center from october 1961 to september 1980. We review the clinical records of the case and re-classify the pathologic diagnosis base on the WHO Classification proposed by Mostofi and Sobin. The results are as the follows. 1) According to histopathologic type, embryonal carcinoma, infantile type 8 cases(26.7%), teratoma 8 cases(26.7%), teratoma 8 cases(26.7%), seminoma 4 cases(13.3%) rhabdomyosarcoma 4 cases(13.3%), germ cell tumor showing more than one histologic pattern 2 cases(6.7%), mailgnant Iymphoma, Iymphocytic, poorly differentiated 1 case(3.3%), malignant mesothelioma 1 case(3.3%), testicular leukemic infiltration 1 case(3.3%) and capillary hemangioma 1 case (3.3%). 2) The mean age of each type is 33 yearn in seminoma, 2 2/12 years in embryonal carcinoma, infantile type, 1 10/12 year in 7 cases of teratoma, and 13 yeArs in rhabdomyosarcoma. 3) Primary testicular tumors occur in the scrotal sac(27 cases, 92%) and cryptorchid testis (2 cases, 8%), Two cases of cryptorchid testns show semieoma. 4) Bilateral testicular tumor is one among 29 cases(7%) 5) Scrotal mass or enlargment is most common chief complaint (74%) at diagnosis. 6) 14 cases (77%) received orchiectomy only an4 9 cases received orchiectomy and other therapy. 7) Metastasis is confirmed in 10 cases(43%) by clinical and operation findings. (clinical record is available in 23 cases among 30 cases).
