While there is some variability in histopathologic description of MRV schwannoma, common features include microcystic/reticular spaces and myxoid
Fine needle aspiration cytology of the mass reveals myxoid
liposarcoma over myxoid
chondrosarcoma and atypical lipomatous tumour.
Pacinian neurofibroma (PN) is a very rare benign dermal tumor that is characterized by the presence of Pacinian corpuscles-like structures in the dermal myxoid
stroma.1 The term pacinian neurofibroma was initially proposed by Thoma in 1894, then by Prichard and Custer in 1952, also by Prose et al.
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 cancer Kate was originally diagnosed with, called Myxoid
Liposarcoma, is extremely rare, forming less than 1% of all cancers diagnosed annually.
Histologically, they can be classified as simple lipoma, fibrolipoma, spindle cell lipoma, intramuscular or infiltrating lipoma, angiolipoma, pleomorphic lipoma, myxoid
lipoma, and atypical lipoma.
MLS/RCLS tissue is composed of round to oval shaped mesenchymal cells and a variable number of lipoblasts, set in a myxoid
matrix with a fine piped capillary network.
chondrosarcoma (EMC) is an uncommon low-grade sarcoma of the soft tissue, usually presenting as a slow-growing mass in men in their fifth to sixth decades.[sup.1] It is characterized by a multinodular growth of primitive chondroblast-like cells in an abundant myxoid
Histopathological examination revealed an intrabdominal fibromatosis with densely collagenised stroma and dilated vessels with myxoid
change [Figure 4].
Some cases may have MIFS-like features, such as myxoid
stroma or ganglion-like cells with prominent nucleoli similar to Reed-Sternberg-like cells.
As described above, liposarcomas are classified into intermediate graded tumors (well-differentiated) and malignant graded tumors (dedifferentiated, myxoid
, pleomorphic, and not otherwise specified).
chondrosarcoma (EMC) is a rare type of sarcoma of the soft tissues that usually presents as a slow-growing mass in men in their 50-60s (1,2).
