Integrated 2-deoxy-2-F(18)-fluoro-D-glucose positron emission tomography combined with computed tomography (FDG-PET/CT) has been used in the field of soft tissue sarcoma. We report an 81-year-old man with dedifferentiated liposarcoma in the left thigh, which was composed of well-differentiated liposarcoma and pleomorphic malignant fibrous histiocytoma. As well as other radiological modalities, ...

Paratesticular liposarcoma is a rare entity. Compared to other genitourinary sarcoma, it is usually detected earlier and is easily resectable, resulting in an excellent prognosis. The recurrence of well-differentiated paratesticular liposarcoma after complete resection is extremely rare. Optimal management of the tumour recurrence includes complete re-excision and radiotherapy to the area of re...

We report a case of paraneoplastic retinopathy associated with a retroperitoneal liposarcoma. A 42-year-old man was referred to our hospital with complaints of night blindness and blurred vision in the peripheral field. Electroretinograms showed a progressive amplitude reduction in his both eyes. Abdominal magnetic resonance imaging showed a large retroperitoneal mass, and pathologic examinatio...

Liposarcoma of the spermatic cord is a rare disease and often mistakenly diagnosed as inguinal hernia, hydrocele, and lipoma. We report the case of a 58-year-old man who presented with persistent discomfort and swelling on the left inguinal region. He was diagnosed with left scrotum lipoma when he was 12 years old. He underwent high orchiectomy and wide resection of the inguinal tumor. Histopat...

Sarcomas are a rare occurrence accounting for roughly 1% of all cancer cases reported. Of these, 9-18% will be identified as liposarcoma. Overall, only 4-9% of all liposarcomas occur in the head and neck region. As such, it is a rare event to see a primary liposarcoma of the aerodigestive tract. These tumors are typically misdiagnosed secondary to their indolent, asymptomatic course and similar...

Liposarcoma is one of the most common sarcomas in adults, but only rarely presents as an esophageal primary. There have been several reports of well-differentiated liposarcoma (WDL) arising in the esophagus, but we present a case of dedifferentiated liposarcoma (DL) presenting as a large esophageal polyp. We believe this is the first reported case of DL of the esophagus with morphologic evidenc...

Liposarcoma is one of the most common subtypes of soft-tissue sarcoma and consists of three main subtypes, of which well-differentiated liposarcoma and dedifferentiated liposarcoma account for 40-45%. The current mainstay of systemic treatment for patients with metastatic or unresectable disease remains doxorubicin with or without ifosfamide in the first-line setting. Recently, eribulin and tra...

INTRODUCTION Liposarcoma of the heart and stomach is rare. PRESENTAION OF CASE We report a case of liposarcoma in both organs with dedifferentiated histology. A patient was referred to our hospital with anorexia and weight loss. Upper gastrointestinal tract endoscopy revealed 5-10-mm elevated lesions, and echocardiography and computed tomography showed tumorous lesions in the left atrium. Tum...

An elderly woman presented with dyspnoea secondary to extensive mediastinal invasion by a primary well differentiated liposarcoma of the mediastinum. Five years after partial resection and postoperative radiotherapy (45 Gy) she is alive and well. To our knowledge, long term survival has not previously been reported for a non-encapsulated mediastinal liposarcoma treated by incomplete resection -...

Dedifferentiated liposarcoma of the mesentery is an extremely rare tumor. A 71-year-old man with a 2-month history of abdominal distention was admitted to our department for evaluation and treatment of an abdominal mass. Computed tomography and magnetic resonance imaging revealed an 11 × 9 cm mass lesion with fat density in the upper right abdominal cavity, displacing the ascending and transver...
