Dedifferentiated Liposarcoma of the Subcutis

The American Journal of Surgical Pathology, 1996
This report describes an 82-year-old woman with dedifferentiated liposarcoma, an extremely rare neoplasm of the subcutis. The patient had first recognized a very soft mass in the anterolateral part of the right thigh more than 20 years earlier, but because the tumor showed little change over this period, she did not seek treatment. She recently noticed

Dedifferentiated liposarcoma of the cheek

Annals of Diagnostic Pathology, 2004
Liposarcomas of the head and neck region are rare; only a few cases have been reported to arise in the cheek or buccal mucosa. Dedifferentiated liposarcoma has rarely been reported in the head and neck region and, to the best of our knowledge, this is the first reported case of dedifferentiated liposarcoma of the cheek.

Dedifferentiated liposarcoma of the liver

Cancer, 1987
Among the rare occurrences of primary malignant mesenchymal tumors of the liver, the development of liposarcoma has been only theoretically listed--there is no proven example in the literature. This article documents a case of primary liposarcoma of the liver in a 30-year-old woman who presented with a huge intrahepatic tumor in the left lobe measuring

Dedifferentiated Liposarcoma

Pathology Case Reviews, 1998
Dedifferentiated liposarcoma is a high-grade nonlipogenic sarcoma that arises in a background of a preexisting well-differentiated liposarcoma. The phenomenon of dedifferentiation is time dependent, and primary or de novo tumors exceed secondary neoplasms in a ratio of 9:1.

Dedifferentiated Liposarcoma of the Transverse Colon

The American Surgeon™, 2021
While liposarcoma is one of the most common soft tissue sarcomas, it is rarely seen within the gastrointestinal tract, and even less frequently seen within the colon. Dedifferentiated liposarcoma is a subtype of liposarcoma, which along with the pleomorphic subtype is considered a high-grade, aggressive tumor; both possess the ability to metastasize ...

Dedifferentiated liposarcoma of the oral cavity with angiosarcomatous dedifferentiation

Virchows Archiv, 2005
We report a unique case of a 42-year-old woman with a dedifferentiated liposarcoma of the soft tissue of the oral cavity with angiosarcomatous dedifferentiation. Liposarcomas compromising the head and neck region are very unusual, and most of the cases in oral cavity show a well-differentiated pattern.

Heterologous Elements in the Dedifferentiated Component of Dedifferentiated Liposarcoma

The American Journal of Surgical Pathology, 1994
Five cases of dedifferentiated liposarcoma in which heterologous elements were present in the dedifferentiated component are presented. Two patients, men 54 and 66 years of age, had retroperitoneal atypical lipomatous tumors (well-differentiated liposarcomas) that recurred (after 2.5 and 12 years, respectively) as dedifferentiated liposarcomas with ...

Dedifferentiated liposarcoma with rhabdomyoblastic differentiation

Virchows Archiv, 2005
Dedifferentiated areas of dedifferentiated liposarcoma (DDL) usually show malignant fibrous histiocytoma (MFH)- or fibrosarcoma-like features and lack any histologic signs of specific differentiation. However, some reports have demonstrated specific differentiation in these areas, with histologic features resembling those of rhabdomyosarcoma ...

Dedifferentiated Liposarcoma Masquerading as Rhabdomyosarcoma

Applied Immunohistochemistry & Molecular Morphology, 2017
We present a rare case of retroperitoneal dedifferentiated liposarcoma (DDLPS) masquerading as rhabdomyosarcoma. The patient was a 74-year-old man, complaining a loss of appetite. Abdominal computed tomography revealed a retroperitoneal mass, 10 cm in diameter, between the liver and the right adrenal gland.
