1), (9) Well-differentiated liposarcomas show predominant fat attenuation components where as dedifferentiated and myxoid
types manifest mainly as soft tissue attenuation masses.
Cartilage tumors are more frequently benign than malignant, and are characterized by the formation of hyaline or myxoid
The fetal type, which was first described by Dehner in 1972, (2) includes two subtypes: the myxoid
, or classic, type, characterized by an abundance of myxoid
matrix, and the cellular, or intermediate, type, characterized by a proliferation of elongated spindle cells.
The 37-year-old endured a six week course of chemotherapy, causing internal and external burns, in a bid to beat myxoid
0% in extraskeletal myxoid
chondrosarcoma, a rare soft tissue sarcoma), but were frequently observed in other types, including triple-negative breast cancer (TNBC, a subtype of breast cancer that lacks estrogen receptors, progesterone receptors, or large amounts of HER2/neu protein; 70%), bladder cancer (73%), microsatellite instability high (MSI-H) colon cancer (77%), non-small cell lung cancer (NSCLC, 75%), endometrial cancer (86%), and ovarian cancer (93%).
Histologically, leiomyosarcoma and IMT may have components of spindled cells with fibrillar eosinophilic or vacuolated cytoplasm; the background stroma may be extensively myxoid
and in both may include aggregates of inflammatory cells, predominantly lymphocytes and plasma cells; although leiomyosarcoma typically exhibits at least mild to moderate nuclear pleomorphism, necrosis and atypical mitotic figures.
5) There are reports of valvular involvement leading to severe aortic regurgitation requiring valve replacement, while the histopathology of the native valve showed features typical of GPA, and another case demonstrated myxoid
degeneration which was most likely due to vasculitis of the blood vessels supplying the aortic valves.
On cut section, their color is gray-white to yellow with a macroscopic appearance from fascicular to myxoid
Singly scattered cells and myxoid
substance were also observed in the haemorrhagic background.
They detail the principles and practice of biopsy diagnosis and management of these lesions, ancillary techniques for the evaluation and diagnosis of bone and soft tissue neoplasms, spindle cell tumors in children and adults, giant cell tumors, myxoid
lesions, lipomatous tumors, vascular tumors, pleomorphic sarcomas, osseous tumors, cartilaginous neoplasms, small round cell neoplasms, epithelioid and polygonal cell tumors, and cystic lesions, and their clinical, cytologic and histologic, and radiographic features and differential diagnosis, with clinical vignettes.
It was composed of fibroblast-like, slender spindle cells with myxoid
An ultrasound-guided needle biopsy of the lesion, prepared for rapid cytologic evaluation using hematoxylin and eosin, showed a myxoid
chondroid matrix with chondrorytes present (Figure 2).
