- Solitary fibrous tumor of the pleura is rare but should be included in the differential diagnosis of a peripheral pulmonary nodule. Cytologic features of solitary fibrous tumor of the pleura is not familar to the pathologist and may be misdiagnosed as malignancy. We report fine needle aspiration cytologic(FNAC) findings of a case of solitary fibrous tumor misdiagnosed as adenocarcinoma in a 48-year-old woman. The FNAC displayed a mixture of bland-looking spindle cells and clusters of epithelioid cells, which have hyperchromatic nuclei with prominent nucleoli. The helpful finding to distinguish it from other circumscribed benign and malignant lesions is the presence of fibromyxoid matrix admixed with blood vessels and thin collagen fibers. Familiarity with these features is essential to avoid misdiagnosis and overtreatment.

Abstract

- The evaluate the diagnostic findings of salivary gland tumors, we reexamined aspiration cytology smears of 7 cases of pleomorphic adenoma, 3 cases of adenoid cystic carcinoma, and 3 cases of mucoepidermoid carcinoma, performed during April 1986 to March 1990, which were comfurmed by surgical excision and histologic diagnosis.
The results obtained are summarized as follows :
1. All cases of pleomorphic adenoma showed branching cellular clusters of epithelial and myoepithelial cells. Acellular elements including myxomatous and chondroid components were observed. There were no cellular pleomorphism and nucleoli. Keratinizing squamous epithelial cells and keratin pearls were noted.
2. The smears of adenoid cystic carcinoma showed cell balls or cell cords containing a central hyaline core. Nuclear atypism and the nucleoli were frequently observed. There were no keratinizing squamous epithelial cells.
3. The smears of mucoepidermoid carcinoma showed mainly sheets or clusters of intermediate cells and some mucin-producing cells. Some nuclear pleomorphism was observed. Mucinous material and many inflammatory cells were present in the background.
