Paratesticular liposarcoma: a case report

Abstract

Paratesticular liposarcomas (PLS) is a very uncommon pathology type of paratesticular sarcomas, with less 200 similar cases reported to date in the English literature. There are a few cases regarding giant paratesticular liposarcoma measuring over 10 cm. We present an unusual case with a giant well differentiated PLS of the left testis extended to the pelvic cavity. We report the case of a 55-year-old man who presented with large left groin mass. The patient underwent left orchiectomy following a cure of a scrotal hernia. Histological and immunohistochemical findings were suggestive of a well-differentiated liposarcoma of spermatic cord. The surgical margins were positive. Metastatic work-up, which included CT of the thorax, abdomen and pelvis, did not reveal any distant metastasis in thorax but there is a left pathological external iliac lymph nodes and a left lateroplevic lipomatous mass extended to the iliac fossa and left parietocolic gutter up to the umbilicus measuring 15x7x17 cm. Our patient refused treatment. A review of the literature revealed that there are fewer cases of giant well differentiated paratesticular liposarcoma extended to the pelvic cavity were reported. This study focuses on the clinical characteristics and treatment of this rare type of tumours.

Diagnosis and Prognosis of Retroperitoneum Liposarcoma: a single Asian center cohort of 57 cases

“…[5] LPS mostly occurs in extremities, followed by retroperitoneum, and there are also literatures reporting LPS founded in rare locations, such as mediastinum, larynx or paratesticular. [20][21][22] High occurrence of retroperitoneum may be attributed to metastasis of LPS from other parts of body, especially where fat is abundant. [1,2,23] Primary retroperitoneal LPS usually originates in the perirenal fat, and there were 19 (33%) perirenal LPS or LPS directly invading kidney in our cohort.…”

Paratesticular liposarcoma: Two case reports

“…Atypical liposarcoma/well-differentiated liposarcoma (ALT/WDLPS) is the most common type of liposarcoma. ALT/WDLPS is mostly distributed in the retroperitoneum and deep tissue of the extremities and mediastinum, but rarely in the scrotum[ 2 ], with fewer than 200 similar cases reported to date in the English literature[ 3 ]. Surgery is currently the most effective treatment for patients with liposarcomas.…”

Testicular liposarcoma: a rare form of testicular cancer

“…3 Testicular liposarcoma are a very rare variant of genitourinary malignancies occurring more often in the spermatic cord where it accounts for less than 12% of all liposarcomas. 1,4,5 Liposarcomas of the spermatic cord usually begin to grow directly below the external inguinal ring, so as the tumor becomes enlarged , it presents as scrotal mass rather than an inguinal mass. 6 Due to the scarcity of cases, there is no consensus on the best treatment and this entity is still very challenging for clinicians in terms of management.…”

“…6 Due to the scarcity of cases, there is no consensus on the best treatment and this entity is still very challenging for clinicians in terms of management. 1 In this paper, we present the case of well differentiated sclerosing type liposarcoma of the left testes. We are writing this case as only a few cases of testicular liposarcoma of the sclerosing type has been reported in the literature.…”
