Abstract

Background

Solitary fibrous tumor (SFT) is a rare mesenchymal tumor that usually occurs in pleura, or less commonly, in the extrapleural space (extrapleural SFT).

Case presentation

Here, we report on an extrapleural SFT originating from the right axilla that occurred at about the same time as a fibroadenoma of the right breast in a 37-year-old woman. The patient noticed stiffness in her right axilla; neoplastic masses were detected in her right breast and axilla using ultrasonography. Cytology from a fine needle aspiration biopsy showed oval-to-spindle-shaped atypical cells with ropy fragments from the axilla; the sample was diagnosed as extrapleural SFT. The breast tumor was diagnosed as fibroadenoma.

Discussion

Cytological reports of extrapleural SFT are few. Future case accumulation could provide data on which to base guidelines for discerning benign from malignant SFT.

Key words

Extrapleural solitary fibrous tumor, fine needle aspiration biopsy cytology, fibroadenoma of breast, case report
