Pure embryonal carcinoma of the testis in an adult male patient: case report

Abstract

As a case presentation, the present paper aims to present a patient with pure embryonal carcinoma, which is rarely seen, together with the relevant literature. Th e case is a 36-year-old male patient, who applied to the clinic with complaints of pain and swelling in the left testis. In the scrotal doppler ultrasonography, hypoechoic solid lesion contoured to the lobule almost fi lling the left testis and having the size of 25x60 mm were observed. Histopathological and immunohistochemical analysis of the this case was diagnosed with pure embryonal carcinoma. All the patients with complaint of pain-free mass in testis should be investigated. Although the pure embryonal carcinoma is rarely seen, it is one of the tumors that can be clinically and histopathologically confused with other testis tumors and should be considered for the patients applying to the clinic with complaints of pain-free mass in testis.

Unusual Presentation of Embryonal Carcinoma of the Testis: A Case Report

“…Embryonal carcinoma is a rare type of non-seminomatous germ cell tumor, representing only 1%-5% of all cases [1][2][3]. It is the second most commonly (80%) observed component of mixed germ cell tumors after seminoma [4].…”

“…Approximately 66% of patients with embryonal carcinoma are found to have metastasis at the time of diagnosis [ 5 ]. These tumors tend to have an aggressive course due to their early tendency to invade other parts of the body [ 3 , 1 ]. Early diagnosis and treatment are, therefore, critical for a positive outcome [ 1 ].…”

“…Like many other testicular tumors, embryonal carcinoma is often discovered by the patient or during routine exams as a painless or occasionally painful lump [ 1 ]. The first imaging method used for such cases is ultrasound, which typically shows a well-defined and heterogeneous lesion [ 1 ]. However, according to our research, it is rarely revealed by left lumbar pain or renal colic.…”
