Why the study?
Primary malignant fibrous histiocytoma of the chest wall is extremely rare and aggressive, and surgical resection is not generally recommended when distant metastasis is suspected.
Radical en bloc resection can lead to long-term survival in patients with chest wall MFH even when initial presentation mimics distant metastasis.

May inform decisions for rare chest wall sarcomas; hypothesis-generating and should not yet change practice.
Primary malignant fibrous histiocytoma (MFH) of the chest wall is extremely rare and is characterized by aggressive features, including a high incidence of local recurrence and distant metastasis. Surgical resection of the chest wall is the primary modality of management. However, surgical treatment is not generally recommended in patients with evidence of distant metastasis. Here, we present a case of chest wall MFH along with a schwannoma mimicking distant metastasis in the right upper arm. The patient was treated by radical en bloc resection and survived for more than 9 years without recurrence.
