Abstract

Myxoid pleomorphic liposarcoma (MPLPS) is an extremely rare entity that has been recognized and included in the literature recently. Liposarcomas are adipocytic tumors that are usually located in the extremities and retroperitoneum. Paratesticular liposarcomas are extremely rare malignant tumors originating from the adipose tissue of the paratesticular region. Myxoid pleomorphic liposarcoma (MPLPS) is an exceedingly rare variant of liposarcoma, with very few cases reported in the literature so far. Mediastinum is the most common site for MPLPS followed by the limbs, head, and neck. We report a case of a 50-year-old male patient who presented with a swelling in the right inguinal region, which came to the patient's attention in the past month. After investigations, a right-high orchidectomy was done. Histopathological examination and immunohistochemistry were performed and a diagnosis of myxoid pleomorphic liposarcoma (MPLPS) involving the spermatic cord was made. So here we report this case of myxoid pleomorphic liposarcoma involving the spermatic cord for the first time in the literature.

摘要

黏液样多形性脂肪肉瘤（MPLPS）是一种极其罕见的肿瘤，最近才在文献中得到确认并被纳入其中。脂肪肉瘤是一种脂肪细胞性肿瘤，通常位于四肢和腹膜后。睾丸旁脂肪肉瘤是起源于睾丸旁区域脂肪组织的极其罕见的恶性肿瘤。黏液样多形性脂肪肉瘤（MPLPS）是脂肪肉瘤中一种极为罕见的变异类型，迄今为止文献报道的病例极少。纵隔是MPLPS最常见的发病部位，其次是四肢、头部和颈部。我们报告一例50岁男性患者，其右侧腹股沟区出现肿胀，在过去一个月引起患者注意。经过检查后，进行了右侧高位睾丸切除术。进行了组织病理学检查和免疫组化，诊断为累及精索的黏液样多形性脂肪肉瘤（MPLPS）。因此，我们在此首次在文献中报告这例累及精索的黏液样多形性脂肪肉瘤病例。
