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. Tte 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 cryptorchi4 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) .
