... ). Only one reported case expressed desmin ( 15 ). Variable expression may also be seen with calponin and muscle-specific antigen (MSA). No published case of cardiac IMT has documented definitive immunohistochemical evidence of anaplastic lymphoma kinase 1 (ALK-1) expression ( 8 ). One tumor was tested...

... arguments in favor of surgery in younger individuals. Cardiac Inflammatory Myofibroblastic Tumor. Inflammatory myofibroblastic tumors (IMTs) of the heart have a much more prominent inflammatory infiltrate, and the tumor cells are stellate (rather than spindled). IMTs tend to involve the valves...

... and punctuated with small blood vessels. Inflammatory myofibroblastic tumors (IMTs) are uncommon lesions found mostly in the lung, but they are increasingly recognized in extrapulmonary sites. The pancreas is rarely involved ( 73 , 74 ). IMT is defined as a neoplasm composed of myofibroblastic spindle...

... architecture). Distinction from smooth muscle tumors can generally be made on morphologic grounds, but in cases with overlap, an immunohistochemical panel including S-100 protein, CD34, desmin, and caldesmon distinguishes these tumors. Inflammatory myofibroblastic tumor (IMT) may show...

... proliferation of plasma cells. Historically, PCG was considered within the spectrum of inflammatory myofibroblastic tumor (IMT) and some controversy still exists as to whether it truly represents a distinct entity or should be recognized as a morphologic variant of IMT ( 281 ). The thyroid gland is rarely...

... ). Rhabdomyosarcoma is rare in adults and is characterized by a diffuse infiltration of small blue round cells with scant cytoplasm with alternating cellular and myxoid zones. Table 3-19 DIFFERENTIAL DIAGNOSIS OF SPINDLE CELL LESIONS Feature PSCN ^a IMT Sarcomatoid Carcinoma Leiomyosarcoma...

..., as were the pregnancy-associated IMTs. Most of the placental IMT cases were from livebirths but one case of placental IMT was associated with a term stillbirth, with the IMT thought to be unrelated to the stillbirth. The scant data on maternal follow-up has been benign with no recurrences ( 149 , 151...
