Abstract

Introduction: Cellular fibrohistiocytoma (CFH) is a type of fibrohistiocytic tumor that commonly occurs in the dermis and superficial subcutis. The designation is used for lesions that show increased cellularity with a fascicular growth pattern and frequent extension. Our search of literature only revealed one case of a primary CFH of the lung. We experienced a rare patient with a primary CFH of the lung.

Presentation of case: We herein present a rare case of a 77-year-old female patient without a cutaneous lesion, who underwent resection for what was considered to be a primary CFH of the lung. There has been no recurrence including a cutaneous lesion in a year after surgery.

Discussion: CFH is considered to be benign, but rare cases showing multiple recurrences and involving metastasis to the lymph nodes and internal organs have been reported. At present, it is not possible to predict this aggressive biological behavior based on the tumor histology.

Conclusion: It is essential to perform resection with an adequate margin with close clinical follow-up.
