UNASSIGNED: We report a case of a 43-year-old female, presented with complaints of @entity1353 for 1 month and had three episodes of @entity1163 in the past two months. On clinical evaluation, bilateral pedal @entity4 was noticed. Echo cardiogram revealed large left @entity4461 measuring 5.7x4.3x4.3 cm. Ultrasound whole abdomen was normal. We received an excised mass with right pulmonary vein end arterectomy speciemen. Histopathology of the mass revealed characteristic features of @entity1822 with grade III, according to FNCCS grading system. The @entity5 was consistent with substantial amount of poorly differentiated fasicles of pleomorphic spindle cells and brisk atypical mitosis, with marked @entity39 . Immunohistochemistry revealed the @entity5 cells in strong diffuse cytoplasmic positive for smooth muscle actin and Ki-67 showed 15-20% of @entity5 cells postivity. The prognosis depends on the individual @entity5 origin for individual site, size of @entity5 and depth of @entity5 than histological features. @entity358 were assumed to be misinterpretation of left @entity1822 with growth of the @entity5 into pulmonary vein lumen. We report this case in view of its extreme rarity.
