We report a case of a rapidly progressing giant retroperitoneal liposarcoma weighing 22 kg in a 41-year-old Japanese man, successfully treated with surgical excision. To our knowledge, this is the largest liposarcoma in the Japanese population reported in the literature.

We report a case of metastatic liposarcoma in the bone marrow with a rapidly fatal course. In view of the poor prognosis and paucity of clinical and imaging findings in patients with high-grade liposarcoma that is metastatic to bone marrow, we propose that bone marrow examination should be performed during the patient's initial evaluation as well as follow-up examinations.

Liposarcoma is one of the most common primary neoplasms in the retroperitoneum, whereas primary mesenteric liposarcomas are rare. We encountered a case of liposarcoma which arose from the mesentery of the jejunum that was diagnosed by imaging studies before surgical operation.

BACKGROUND Dedifferentiated liposarcoma is an uncommon variant of liposarcoma, with poor prognosis and higher preponderance to local recurrence. Only nine cases of dedifferentiated liposarcoma of small bowel mesentery have been reported till now. This is a case of giant dedifferentiated liposarcoma of the small bowel mesentery, weighing nearly 9 kg (19.8 lbs), with synchronous lesions in the ex...

O liposarcoma (LPS) é um tumor mesenquimatoso maligno do tecido adiposo. A sua localização no mesentério rara. Homem, 64 anos, enviado à consulta após colonoscopia de rastreio ter revelado lipoma da parede sigmoide. Realizou Tomografia computorizada abdominopelvico (TC AP): ~ confirmou e “…no jejuno-ileal - massa sólida, suspeita GIST ou neuroendócrino”. PET-DOTANOC mostrou: “fraca expressão re...

Note Sarcomas are relatively rare malignant tumours and comprise less than 10% of all cancers. Classical classifications of sarcomas are based on the site of tumour (bone or soft tissue). Soft tissue sarcoma (STS) is the collective term used for malignancies arising in muscles, fat, vessels, the peripheral nervous system and fibrous tissue. Histopathologic examination of such tumours has reveal...

Liposarcomas are one of the most common primary lesions of the retroperitoneal region. They rarely exhibit intra-abdominal location. Because the symptoms emerge later on, they often remain unnoticed until they grow large. Our aim in this paper is to present a case of myxoid liposarcoma of descending mesocolon origin, 40 cm wide and weighing 7000 g, seen in a 47-year-old male patient. No cases a...

RATIONALE Pleomorphic liposarcoma (PLS), is a rare subtype of liposarcoma, and is considered to be of the highest malignancy grade. PATIENT CONCERNS We aimed to analyze the clinical features, diagnosis, treatment, and recurrence of the 6 cases of PLS. DIAGNOSES Six cases with confirmed pathological PLS presented at out hospital from January 2003 to January 2017. The postoperative pathology ...

background: a possible mechanism by which hyperthermia enhances tumor immunogenicity is the induction of nkg2d ligands on tumor cells. although the expression of mhc class i chain-related protein a and b (mica/b) has previously been reported in different carcinomas, there is no information about mica/b expression in liposarcomas. objective: to investigate mica/b induction in a human liposarcoma...
