It used to be called a malignant fibrous histiocytoma (MFH). Undifferentiated pleomorphic sarcomas are more commonly in people aged 60 to 70. They can affect any part of the body, but most commonly develop in the legs and arms. The relationship between AFX, pleomorphic dermal sarcoma, and undifferentiated pleomorphic sarcoma (UPS), a soft tissue neoplasm that shares many histologic features with AFX, is unclear . While some authors consider AFX a less aggressive, superficial variant of pleomorphic dermal sarcoma and UPS, many others view AFX as a distinct malignancy.

As in the majority of the cases, UPS affects the extremities, this article focuses on musculoskeletal involvement. Undifferentiated pleomorphic tumor involving the dermis that histologically looks like an atypical fibroxanthoma and has any of the following: Size > 2 cm Shows extensive involvement of deeper tissue (subcutis, skeletal muscle, fascia) Anaplastic rhabdomyosarcoma (also called pleomorphic rhabdomyosarcoma) is an uncommon type that occurs mainly in adults and is very rare in children. Some doctors also group undifferentiated sarcomas with the rhabdomyosarcomas. Pleomorphic morphology is characteristic of pleomorphic liposarcoma, pleomorphic rhabdomyosarcoma, and—as a diagnosis of exclusion—undifferentiated pleomorphic sarcoma. Table 1.

It is considered a diagnosis of exclusion for sarcomas that cannot be more precisely categorized. Other sarcomas are cancers that form in bone and soft tissues, including muscle, fat, blood vessels, lymph vessels, and fibrous tissue.

Although MFH was previously one of the most common soft tissue sarcomas, primary UPS/MFH of the lung is now a rare clinical finding, with few reports in the literature in recent years. Undifferentiated pleomorphic sarcoma (UPS): an aggressive type of soft tissue sarcoma with high incidence of local recurrence and metastasis, most common in the age group of 50-70 years. Leiomyosarcoma: a malignant smooth muscle tumour that arises most commonly in the limbs, abdomen and uterus. Indeed, although small round cell sarcomas, liposarcoma, and synovial sarcoma have a high interobserver reproducibility, the classification of pleomorphic sarcomas is reported to be much less reproducible. 23 For this reason, these tumors may be considered empirically as pleomorphic sarcomas with myoid antigen expression, without further classification. 2019-08-19 · Background Primary sarcoma of the lung is a very rare malignant tumor accounting for less than 0.5% of all lung tumors and presenting diagnostic and treatment challenge.
