Rezumat: Although extremely rare, the primitive lung hemangiopericytoma in adults is similar to hemangiopericytomas with other soft tissue localizations. Although generally benign and curable after radical surgery, it might also have a malignant clinical course with dissemination in both lungs, infiltration of vital organs heart, pulmonary arteryextension to the adjacent tissues, and even pulmonary metastases.

Over the years, the conventionally-defined hemangiopericytoma concept has evolved because of the nonspecific histologic growth pattern characteristic monotonous appearance, moderate or high cellularity, and a well-developed lung cancer benign vs malignant vascular pattern shared by numerous, unrelated benign or malignant lesions.

We report an uncommon case of primitive lung tumor exhibiting hemangiopericytoma-like features, with an aggressive, fatal clinical course. Because of the major histologic overlap between solitary fibrous lung cancer benign vs malignant and hemangiopericytoma and lack of clear classification criteria, we encountered difficulty in including this case in a known clinical entity; primitive solitary fibrous tumor of the lung, which mimics lung hemangiopericytoma, seemed to be the most plausible diagnosis.

We discuss the case particularities and the radiologic and pathologic correlations.
