Although liposarcoma often metastasizes to various organs, cardiac metastasis, including to the pericardium, is rare. We present a case of a third recurrence of pericardial metastasis from the thigh, which required surgical resection because of cardiac failure. Surgery was effective for improving cardiac function and reintroducing chemotherapy. This is the first reported case of metastatic peri...

Orbital liposarcoma is a rare and usually unsuspected neoplasm. Over a five-year period three female patients aged 22, 71, and 77 years presented with primary myxoid liposarcoma of the orbit. The management of one patient was complicated by a history of orbital decompression for suspected thyroid eye disease. The tumour infiltrates locally beyond a deceptive pseudocapsule, and surgery has to be...

Retroperitoneal liposarcoma is an infrequent, locally aggressive malignancy. We report two cases of huge retroperitoneal liposarcomas. The presence of a palpable abdominal mass was a common symptom of the two patients. Preoperative imaging study showed huge retroperitoneal tumors. Both patients underwent complete surgical resections, and a negative microscopic margin was achieved in both cases....

Sarcomas of breast are rare tumors. Primary mammary liposarcomas are rarer still. Peak incidence of breast liposarcomas in adults occur between 4th and 6th decades. We report a case of primary breast pleomorphic liposarcoma in a 70 years old female patient. FNAC of the tumor was non-specific. However, histopathological along with immunohistichemical studies clinched the diagnosis.

Multiple mesenteric well-differentiated (WD) liposarcoma is an extremely rare entity. The present study describes a case of multiple mesenteric WD liposarcoma, complicated by purulent inflammation, in a 59-year-old male who presented with abdominal pain and pyrexia of unknown origin. A computed tomography scan of the abdomen revealed a large, non-encapsulated mass in the abdomino-pelvic cavity,...

INTRODUCTION Liposarcoma is the most commonly diagnosed soft tissue sarcoma in adults and occurs predominantly in the lower limbs and retroperitoneum. Primary mediastinal liposarcomas are rare.They are often asymptomatic and when growing to large size the presenting symptoms are related to direct invasion or compression of other thoracic organs such as the heart, great vessels and lung. CASE ...

BACKGROUND Liposarcoma is the second most common soft tissue sarcoma in adults with a peak incidence between the 4th and 6th decade of life and slight preponderance to the male gender. It originates from multipotential primitive mesenchymal cells, rather than mature adipose tissue. CASE PRESENTATION An unusual case of a rapidly growing giant lipoma-like liposarcoma of the left gluteal and per...

BACKGROUND Hepatoid adenocarcinoma (HAC) is a peculiar type of extrahepatic adenocarcinoma generally characterized by adenocarcinomatous and hepatocellular carcinoma (HCC)-like foci. Stomach is the most frequent site where hepatoid adenocarcinoma occurs, although it has been described in many other organs. On the other side, liposarcoma is a rare, malignant tumor that develops from fat cells. ...

Paratesticular liposarcoma is a very rare cause of scrotal mass. It is thought that they arise from spermatic cord lipomas most commonly. While well differentiated tumors tend to share many histological similarities with dedifferentiated tumors, the latter has a much more aggressive phenotype. We present an unusual case of a 69-year-old male with synchronous prostate adenocarcinoma and unilater...

TAZ (WWTR1) and YAP are transcriptional coactivators and oncoproteins inhibited by the Hippo pathway. Herein we evaluate 159 sarcomas representing the most prevalent sarcoma types by immunohistochemistry for expression and activation (nuclear localization) of TAZ and YAP. We show that 50% of sarcomas demonstrate activation of YAP while 66% of sarcomas demonstrate activated TAZ. Differential act...
