Histopathological analysis of testicular tumors: a 4-year experience

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.

Occurrence of Testicular Tumours in Dogs

ABSTRACTIn the Department of Physiology and Pathology we examined the testes of 40 dogs. They were examined grossly and for histological examination they were fixed with Bouin's solution, embedded in paraffin, sectioned and stained with haematoxylineosin stains. PAS reaction and imunohistological assays were performed.The dogs were divided into three groups considering their age: </= 5 years of age, from 6 to 9 and from 10 to 16 years of age. There were 19(47%) mongrels amongst these dogs. From 40 examined dogs the most common pathologies were tumours (42%) and degenerations (29%). The highest level of the tumours was found in the 7, 8 and 10 year old dogs. In 10 cases we found testicular tumours in the 10 years and older dogs, in 7 cases—in the 6–9 year old dogs, and there were no testicular tumours in dogs aged 5 years and younger. The most common occurrence of testicular tumours were seminomas (52%). Seminomas were mostly found in the 10-year and older dogs testes, also in cryptorchidic testes. Leydig-cell and Sertoli-cell tumours were diagnosed in 24% of dogs. In two cases we found Leydig-cell tumours with intratubular seminomas, both within one testis and in one case—different types of Leydig-cell tumour in one dog's testes. We found both types of Sertoli-cell tumours in the cryptorchidic testes and in the one testis they were found together with seminoma. We didn't find any signs of the feminization syndrome in these dogs.

Epidemiology of testicular tumors in Slovakia (1993-1997): preliminary report.

Worldwide increase of the incidence of testicular tumors was also reflected in the increasing number of these malignancies in the Slovak Republic. Lack of the accurate information about the occurrence of testicular tumors in Slovakia has helped to create a new multicentric retrospective study based on occurrence, histology, risk factors, diagnosis and treatment of this malignancy in Slovakia. The analysed study group consists of 1010 patients with testicular cancer, diagnosed from the beginning of 1993 to the end of 1997. Identification and histological data about the patients were obtained from the heads of departments of urology in Slovakia. In this study considerable differences were found between information obtained from departments of urology and information published by the National Cancer Register of the Slovak Republic. Ascertained information is higher than the one published by the National Cancer Register from the last five officially concluded years.
