sarcoma," BMJ Case Reports, 2014.
Various other terms also had been used for the dermal neoplasms, such as neurothekeoma, nerve sheath myxoma, benign myxoid
tumor of nerve sheath, perineural myxoma, bizarre cutaneous neurofibroma.1,3 However, some authors consider that the term pacinian perineural cell fibroma may describe it better.2
Based on microscopical features they are classified into classic lipoma, fibro lipoma, angiolipoma, spindle cell lipoma, and pleomorphic, myxoid
, sialolipoma, and intramuscular lipomas .

liposarcoma," Nature, vol.
Gross pathological examination revealed a well-circumscribed, solid and cystic, nodular paratesticular mass, with a myxoid
tan to red-brown cut surface, with hemorrhagic contents and no calcification.
Deep fibromatosis shows variable attenuation, similar to or slightly higher than that demonstrated by skeletal muscle, with hyper/hypoattenuation, probably reflecting collagen and myxoid
Scattered inflammatory cells and/or focal myxoid
changes of the stroma may be seen in some cases.
liposarcomas have an inhomogeneous appearance on CT and MRI, especially under contrast, and may even appear cystic on MRI.
chondrosarcoma: a multi-institutional study of 42 cases in Japan.
(1) IMT belongs to a group of pseudosarcomatous conditions with many names including plasma cell granuloma, plasma cell pseudotumor, inflammatory myofibrohistiocytic proliferation, omental-mesenteric myxoid
hamartoma and, most commonly, inflammatory pseudotumor.
Macroscopically cutting the surface of a cystic tissue sample totally 6 x 4.5 x 3 cm dimensions was bloody, and a solid myxoid
area of 3 x 2.5 cm was observed on one side (Figure 1b).
Due to the vast range of histological appearance at the MFH diagnosed tumors, they were further subdivided into (1) storiform-pleomorphic, (2) myxoid
(myxofibrosarcoma), (3) giant cell, (4) inflammatory, and (5) angiomatoid .
Different forms of liposarcoma are described: atypical lipomatous tumor/well differentiated (ALT/WD), dedifferentiated liposarcoma (DDLs), myxoid
liposarcoma (MLs), and pleomorphic liposarcoma (PLs) [2-5].
liposarcoma (MLS) is a subtype of liposarcoma that represents a distinct pathological entity characterized morphologically by tumor cells within a myxoid
stroma with a rich, branching thin-walled vasculature, and focal lipomatous differentiation.
On microscopic examination, the tumor contains alternating hypocellular myxoid
areas and hypercellular areas.
