Primary pulmonary myxoid sarcoma: Rare entity
Shroque Zaher
Consultant Histopathologist, UAE
T
his case represents a rare entity-primary pulmonary myxoid sarcoma, of which to the best of our knowledge only 10 other
cases have been reported in the literature. They are defined by distinctive histo-morphological features and characterized
by a recurrent fusion gene. All tumors involved pulmonary parenchyma with a predilection for the endobronchial component.
They appear to have a predilection for females, with 7 of the 10 reported cases, occurring in women. Microscopically, they are
lobulated tumors comprising cords of polygonal, spindle, stellate cells with myxoid stroma, morphologically reminiscent of
extra-skeletal myxoid chondro-sarcoma. Tumors were immune-reactive for only vimentin and weakly focal for EMA, although
our specific case was negative for these markers. In 7 of the 10 tumors, a specific
EWSR1-CREB1
fusion gene was demonstrated
by reverse transcription-polymerase chain reaction. This gene fusion has been described previously in 2 histologically and
behaviorally different sarcomas: Clear cell like sarcoma-like tumors of the gastrointestinal tract and angiomatoid fibrous
histiocytoma; however, this is a novel finding in tumors with the morphology described and occurring in the pulmonary
region.
