What is round cell liposarcoma?
Myxoid/round cell liposarcoma, or MRCLS, is one of several types of liposarcoma. Liposarcoma is a rare cancer that grows in the cells that store fat in the body. MRCLS usually grows in the arms and legs. These tumors grow slowly, and they can spread to other parts of the body.
What is a round cell tumor?
The term round cell tumor describes a group of highly aggressive malignant tumors composed of relatively small and monotonous undifferentiated cells with increased nuclear-cytoplasmic ratio.[1] Malignant small round cell tumors (MSRCT) is a term used for tumors composed of malignant round cells that are slightly larger …
Can Round cells be benign?
However, cells range in morphology from discrete round cells to epithelioid to spindled cells and these cells can be highly variable in both benign and malignant forms. If poorly granulated, these cells are easily mistaken for other tumor types.
Can cancer cells be round?
Desmoplastic small round cell tumor (DSRCT) is a type of cancer. It is usually found in the abdomen (belly), but it can also occur in other parts of the body. Tumors are formed by small, round cancer cells and are surrounded by scarlike tissue.
How quickly does liposarcoma spread?
Well-differentiated liposarcoma is the most common form. It grows slowly and generally does not spread to other parts of the body. Well-differentiated liposarcoma has a tendency to regrow after initial treatment.
What do round cells indicate?
Discrete (round) cell neoplasms. Discrete or round cell tumors often are of hematopoietic origin (lymphoma, histiocytic, mast cell tumor) and as the term suggests, consists of individualized round cells. Cells tend to exfoliate readily and aspirates are often of high cellularity.
What are the types of round cell tumors?
Round cell tumors fall into a few different categories: mast cell tumor, histiocytoma, lymphoma, plasmacytoma, and transmissible venereal tumors. Melanomas are the cytologic “great pretender” and, although classified as mesenchymal tumors, can appear as round cell tumors on cytology.
Is melanoma a round cell tumor?
Malignant Melanoma They are generally classified as mesenchymal tumors rather than round cell tumors, but are discussed here because they can resemble epithelial, mesenchymal, or round cell tumors on cytology.
What is a small round blue cell tumor?
Small round blue cell tumor: a group of childhood tumors that is characterized by a similar appearance under the microscope. The appearance is that of small, round, primitive cells that stain blue with conventional staining techniques for biopsy analysis.
Can liposarcoma be seen on ultrasound?
Liposarcoma can be seen on ultrasound. One of the diagnostic imaging tests used to diagnose liposarcoma includes ultrasound. In some cases, ultrasound can be used to help differentiate the type of liposarcoma based on the characteristics found on the sonogram.
When is liposarcoma considered in the differential diagnoses of lingual tumors?
Liposarcoma should be considered in the differential diagnoses of lingual tumors in the dog when cytological evaluation reveals eosinophilic granular cells consistent with GCT. ©2011 American Society for Veterinary Clinical Pathology.
What is liposarcoma mrcls?
Liposarcoma is a rare cancer that grows in the cells that store fat in the body. MRCLS usually grows in the arms and legs. These tumors grow slowly, and they can spread to other parts of the body. How common is MRCLS?
Which immunohistochemical findings are characteristic of well-differentiated liposarcoma?
Immunohistochemically, the cells were uniformly negative for periodic acid-Schiff and did not express smooth muscle actin, desmin, or cytokeratin but were immunoreactive for vimentin and S100. A diagnosis of well-differentiated liposarcoma was made on the basis of morphologic and immunohistochemical results.
What is myxoid/round cell liposarcoma?
Myxoid/round cell liposarcoma, or MRCLS, is one of several types of liposarcoma. Liposarcoma is a rare cancer that grows in the cells that store fat in the body.
