Liposarcomas of the larynx are extremely rare tumors, with only 37 cases reported in the English or French literature to date. The first two cases of laryngeal liposarcomas were reported respectively by Kapur and Dockerty in 1968 [1, 2]. Liposarcoma of the larynx is at high risk of local recurrence and seldom has metastatic potential. Prognosis for this tumor is better than that of non laryngea...

The present study describes a rare case of a mesenteric liposarcoma that resulted in a complete remission (CR) following treatment with trabectedin (Yondelis®). The patient presented with abdominal pain and fever. An abdominal mass was identified that corresponded to a mixed-type high-grade mesenteric liposarcoma with wide areas of necrosis, areas of dedifferentiation and features of a leiomyos...

A 15-year-old, female mixed-breed dog presented with abdominal distention. An exploratory laparotomy revealed a large left ovarian mass (20 × 15 × 12 cm). Histopathological examination of the mass revealed a mixed myxoid liposarcoma and a well-differentiated leiomyoma. Four months after surgical removal of the mass, the dog died due to multiorgan metastasis. The metastasis was composed solely o...

We report a liposarcoma at the mesojejunoileum that was widely excised, and then the intrahepatic metastatic liposarcoma was found. The dog was treated by two single-agent chemotherapy separately. The patient was an 8-year-old, male Dachshund, and was referred to our hospital owing to the significant distention of the left abdomen. Neither radiography nor ultrasonography detected the actual ass...

Liposarcoma originating in the orbit is extremely rare. Herein, we report a dedifferentiated lipo sarcoma arising from the orbit of a Chinese woman. This patient underwent tumor resection at the age of 56 years and recurred 50 months after the initial resection. Histologically, the initial lesion exhibited features of well-differentiated liposarcoma with focal areas of well-differentiated ossif...

An amelanotic malignant melanoma is characterized by little or no pigment. It is frequently misdiagnosed because it is a rare entity in general, and because of its unusual clinical features. Liposarcoma is one of the most common adult soft tissue sarcomas. We encountered a case of amelanotic melanoma with a concurrent liposarcoma. A 68-year-old man presented with a single, 1.5x1.5 cm round eryt...

BACKGROUND The function of promyelocytic leukemia (PML) bodies is not well known but plays an important role in controlling cell proliferation, apoptosis and senescence. This study was undertaken to analyze the clinical significance of PML body expression in primary tumor samples from malignant fibrous histiocytoma (MFH) and liposarcoma patients. METHODS We studied MFH and liposarcoma samples...

Spermatic cord liposarcoma is a rare medical condition and liposarcomas are most commonly found in the retroperitoneum, in the extremities and less often in the head and the neck area. The spermatic cord is a rare site of origin, accounting for about 3-7% of all liposarcomas. We report a case of liposarcoma of spermatic cord. A 62-year-old male patient presented with a painless right inguinal m...

This is a case of a posterior mediastinal mass in an asymptomatic gentleman, which was resected successfully and he has been disease free for more than a year of follow up. The histopathology findings happen to be a rare occurrence.

Background Liposarcomas (LPS) are rare tumors accounting approximately for 19% of adult soft-tissue tumors [1]. The most recent classification of the WHO divides liposarcomas into 3 main clinicopatological and genetic subtypes: myxoid/round cells liposarcoma, well differentiated / dedifferentiated liposarcoma and pleomorphic liposarcoma [2]. The importance of a total macroscopical resection to ...
