Rare Tumours of the Testis: Twelve Years of Experience

Abstract

Rare tumours of the testis includes a wide variety of tumours. We aim to present clinical and histological characteristics of our patients with rare tumours of the testis. The medical records of 33 patients who were treated and followed-up for testicular rare tumours in our center between 2007 and 2020 were retrospectively reviewed. Of all the 243 testicular tumours, 222 cases (91.4%) were germ cell tumours and 21 cases (8.6%) were non-germ cell tumours. Thirty-three rare tumours of the testis including rare germ cell tumours and non-germ cell tumours were detected. The mean age of the patients at diagnosis was 34 years (range 18–68 years). The histological types of rare testicular tumours were as follows: teratoma 4.5% (n=11), sex-cord stromal tumours 4.5% (n=11), paratesticular tumours 3.2% (n=8), and the others [lymphoma 0.4% (n=1), mesothelioma 0.4% (n=1) and choriocarcinoma 0.4% (n=1)]. The median duration of follow-up was 32 months (range 1 to 256 months). None of the patients with non-metastatic disease stage developed recurrence after having received appropriate therapy. Metastatic disease was documented in 9 cases at the time of diagnosis (five patients with teratomas, two patients with Leydig cell tumour, one patient with choriocarcinoma and rhabdomyosarcoma). The most common subtypes of testicular rare tumours in our center was teratoma and sex-cord stromal tumours. Because of testicular rare tumours have different biological features and different clinical outcomes, the management of each tumour requires a different approach.

Testicular mixed germ cell tumor: A case report

“…TMGCTs are composed of two or more types of germ cell tumors and primarily occur in the testis. They account for only approximately 16% of all testicular tumors, and patients usually have a survival period of 20–132 mo[ 4 ], with a median survival period of 42 mo[ 5 ]. Currently, TMGCTs are mostly reported as individual cases in China and other countries.…”

Intra-abdominal undescended testis associated with seminoma manifesting as acute appendicitis; An extremely rare clinical presentation; Case report

“…While these signs present it is more familiar with mind to suspect acute appendicitis or diverticulitis in compare with intra-abdominal tortuous UDT [3]. On the contrary, acute appendicitis could present itself with whether unilateral or bilateral scrotal pain, inflammation, mass, abscess formation, and epididymitis [2,8,[11][12][13][14]. Presence of typical disease history and physical examination for acute appendicitis in a male patient restricts the diagnosis and convince the surgeon to program for emergent classic appendectomy.…”
