Low-grade myofibroblastic sarcoma (LGMS) is a very rare, atypical myofibroblastic tumor with fibromatosis-like features with predilection mostly in head and neck region. LGMS occurs primarily in adult patients with a slight male predominance. Only few cases of LGMS affecting the larynx have been reported in literature to this date. We describe a case of low-grade myofibroblastic sarcoma of the ...

BACKGROUND Congenital peribronchial myofibroblastic tumor is a rare, solid mesenchymal tumor of the neonate, usually associated with non-immune hydrops fetalis. CASE REPORT We present a case of congenital peribronchial myofibroblastic tumor, in whom a right lung mass was detected in intrauterine life. 12 days after delivery by caesarean section, right lobectomy was performed. The tumor was li...

inflammatory tumefaction of unknown etiology. It is relatively rare but could occur at various locations throughout the body (1). Inflammatory myofibroblastic tumors are generally considered a benign mass and include inflammatory cells, histiocytes, and fibroblasts (1). Nevertheless, aggressive features that may mimic a malignant tumor have been described. We present a malignancy mimicking infl...

BACKGROUND Myofibroblastic sarcoma or myofibrosarcoma is a malignant tumor of myofibroblasts and known to develop rarely in the breast, but its underlying lesion and tumor cell origin have never been reported yet. CASE PRESENTATION A 61-year-old female presented with a gradually growing breast mass with well-demarcated ovoid nodular shape. The tumor was histologically characterized by fascicu...

Inflammatory myofibroblastic tumor (IMT) is a rare entity and a diagnostic challenge with myriad clinical presentations and pathogenetic mechanisms. Isolated occurrences can be at any site in the body; however, only a few cases of IMT with the concomitant appearance of different organs have been published. We report a unique occurrence of bilateral inflammatory myofibroblastic tumor of the lung...

Inflammatory myofibroblastic tumors are quasineoplastic lesions that may occur in various anatomic locations. Abdominal involvement is reported, but involvement of the gastrointestinal tract remains rare, and usually occurs in children with poor enhancement pattern in computed tomography (CT) scan. We report a case of an inflammatory myofibroblastic tumor located in the stomach. The good enhanc...

Intraluminal formations of the heart are a heterogeneous group: from blood clots to malignant neoplasms. The nosology these can only be determined by morphological research. Myxofibrosarcoma is rare tumor. According modern concepts, myxofibrosarcoma belongs group intimal sarcomas, subgroup undifferentiated pleomorphic sarcomas. We describe two cases heart: in one subject against background infl...
