Histopathological analysis of testicular tumors: a 4-year experience

Abstract

Background: Testicular cancers are rare in most countries. However, in many Western countries their incidence has been increasing since the middle of the twentieth century. A definite geographic and racial distribution is seen in the occurrence of testicular tumors. Objective: The purpose of this study was to analyze the pattern and distribution of testicular tumors in the patients visiting B.J. Medical College, Ahmedabad, Gujarat, India. Materials and Methods: This was a retrospective study in which cases were retrieved between January 2011 and November 2014 from the electronic database of the Department of Pathology. Pertinent data such as age and histopathology of tumor were collected from the histopathology reports. Results: Testicular tumors were uncommon, comprising only 8.21% (17/207 cases) of all testicular lesions. Most of these tumors (10; 58.8%) were seen between the third and the fifth decades. Germ cell tumors were the most common tumors (12; 70.6%), among which mixed germ cell tumors and seminomas were the most frequently encountered cases. 24.6% of the biopsies consisted of undescended testes and none of them showed malignancy. Other tumors diagnosed were mature teratoma, non-Hodgkin lymphoma, yolk sac tumors, intratubular germ cell neoplasia unclassified, and fibromatosis. One rare solitary case of ovarian tumor (papillary cystadenocarcinoma) was also encountered. Conclusion: Testicular tumors are uncommon in our population. As evident in other parts of the world, germ cell tumor was the common tumor found in this study as well. However, unlike in Western population, no tumor was seen in undescended testis.
