Testicular Embryonal Carcinoma: A Case Report

Embryonal carcinoma is a rare and aggressive type of non-seminomatous germ cell tumor, usually affecting young or middle-aged people. It is often discovered by the patient or during routine medical examinations as a painless or sometimes painful mass. The aim of this article is to present the case of a 25-year-old patient with embryonal carcinoma, who presented to the clinic complaining of pain and swelling of the right testicle. Scrotal ultrasound revealed a hypoechoic, heterogeneous solid lesion. Histopathological and immunohistochemical analysis of this case led to the diagnosis of pure embryonal carcinoma. Although pure embryonal carcinoma is rare, it is one of the tumors that can be confused clinically and histopathologically with other testicular tumors and should be considered in patients presenting to the clinic with complaints mainly of a painless mass in the testis. Multidisciplinary collaboration between urologist, radiologist, oncologist and pathologist is essential to ensure rapid diagnosis and implementation of the most appropriate therapeutic approach in these difficult cases.
