Case in brief

A case of a PRRX1::NCOA1 rearranged fibroblastic tumor was presented, characterized by a well-circumscribed, monomorphic cellular structure with oval to spindle-shaped cells. Immunohistochemical analysis showed patchy reactivity for smooth muscle actin and S100. The presence of the PRRX1::NCOA1 fusion transcript was confirmed, contributing to the understanding of this neoplasm's characteristics and behavior.

Diagnostic / clinical pearl

Clinicians should consider the PRRX1::NCOA1 rearranged fibroblastic tumor in the differential diagnosis of spindle cell neoplasms, especially given its unique molecular signature.

Why it matters

This case highlights the importance of next-generation sequencing in identifying novel neoplasms that are not yet classified by the WHO, emphasizing the evolving nature of tumor classification.
