We report on the rare and surgical treatment of a case of primary mediastinal liposarcoma. A 64-year-old male complained of hoarseness for one month and was admitted to our hospital because of an abnormal shadow, which was postulated to be an anterior mediastinal tumor on a chest computed tomography (CT) scan. Horizontal T1-weighted magnetic resonance imaging (MRI) showed an anterior mediastina...

Background: Liposarcoma is the most common soft tissue sarcomas in adults, and it typically occurs in either the retroperitoneum or extremities. However, this malignant tumor is very rare in the female reproductive system. Case: As 58-year-old female presented with acute abdominal pain, and computed tomography (CT) scan detected multiple masses measuring 4-6 cm in size with a fatty density in h...

BACKGROUND Liposarcomas are among the most common sarcomas of adult life. Pleomorphic liposarcoma, characterized by pleomorphic lipoblasts, is the rarest subtype. To our knowledge only three cases of pleomorphic liposarcoma of the foot or ankle have been reported so far. CASE PRESENTATION A 71-year-old female presented with a large growing mass on the dorsum of her right foot. Computed tomogr...

Primary retroperitoneal liposarcoma is generally regarded as a genetic disorder. We have retrospectively genotyped 8 single nucleotide polymorphisms (SNPs) in 6 candidate genes (MDM2, CDK4, CDC27, FPGS, IGFN1, and PRAMEF13) in 138 patients and 131 healthy control subjects to evaluate the effects of genetic factors on individual susceptibility to primary retroperitoneal liposarcoma in Chinese po...

paratesticular sarcomas have happened rarely. due to the infrequency of this malignant disease and its diverse histopathologic subtypes, no standard treatment would be available. multiple treatments have reported in literature with different results. we have reported a 55 years old man with a 30 years history of paratesticular mass. after multiple operations, radical orchiectomy has revealed li...

We present a case of a dedifferentiated liposarcoma with osteosarcomatous degeneration in a 46-year-old male. The mass, palpated during a routine physical exam, was analyzed with dynamic, contrast-enhanced CT and CT-guided core-needle biopsy before surgical resection.

vulvar liposarcoma is rare and there are only eleven cases reported since 1966.primary sarcoma of the vulva constitutes 1-2% of all vulvar malignancies.Because of their locations and appearance,they may be easily mistaken as bening lesions.this is a report of a 65-years-old wite a vulvar mass similar to a lipoma.the lesion,a soft tissue mass,was totally excised and was sent for pathologic study...

Liposarcoma arising from the mesentery of the bowel is a rare lesion. Some of the most common presenting symptoms of primary mesenteric liposarcoma is increasing abdominal girth, weight loss, abdominal pain, abdominal discomfort with meals and the presence of a freely movable abdominal mass or masses. Our patient presented with a large intra-abdominal mass. Diagnostic laparoscopy revealed tumor...

Myxoid liposarcoma is a subtype of liposarcoma. This specific subtype can be identified based on its characteristic histological and cytogenetical features. The tumor has a fusion transcript of the CHOP and TLS genes, which is caused by t(12;16)(q13;p11). Most of the fusion transcripts that have been identified fall into three categories, specifically type I (exons 7-2), type II (exons 5-2), an...
