INFLAMMATORY MYOFIBROBLASTIC TUMOR Figure 11-16 INFLAMMATORY MYOFIBROBLASTIC TUMOR A: Low-power view shows a well-circumscribed spindle cell lesion that appears to have been “shelled out” at the time of excision. B: At intermediate power, the spindle cells are arrayed in loose fascicles. C More about this image found in INFLAMMATORY MYOFIBROBLASTIC TUMOR A: Low-power view shows a well-circumsc...

MYOFIBROBLASTOMA WITH HETEROLOGOUS CHONDROID DIFFERENTIATION Figure 11-8 MYOFIBROBLASTOMA WITH HETEROLOGOUS CHONDROID DIFFERENTIATION Benign cartilage is present in the center of an otherwise unremarkable myofibroblastoma composed of myofibroblasts and collagen with admixed adipocytes.

PSEUDOANGIOMATOUS STROMAL HYPERPLASIA (PASH) Figure 11-14 PSEUDOANGIOMATOUS STROMAL HYPERPLASIA (PASH) A: Low-power image shows irregular slit-like spaces lined by spindle cells embedded in a dense collagenous stroma, characteristic of PASH. B: Intermediate-power view of the myofibroblasts More about this image found in PSEUDOANGIOMATOUS STROMAL HYPERPLASIA (PASH) A: Low-power image shows irre...

the surrounding stroma. C: High-power view of the epithelioid myofibroblasts characteristic of this entity. These cells may be mistaken for infiltrating lobular carcinoma cells. More about this image found in LYMPHOCYTIC MASTOPATHY A: Low-power view illustrates the perilobular and p...

MYOFIBROBLASTOMA, PALISADED VARIANT Figure 11-6 MYOFIBROBLASTOMA, PALISADED VARIANT A: Low-power view shows a well circumscribed tumor with compact rows of myofibroblasts that characterize the palisaded variant.
