title: Fine needle aspiration cytology of primary squamous cell carcinoma of the thymus. A case report.
abstract: We present the cytologic findings of a rare case of primary thymic squamous cell carcinoma with ultrastructural examination and histologic confirmation of the tumor. The clinicopathologic features of thymic carcinomas are discussed. Although the cytodiagnosis of squamous cell carcinomas in general is not difficult, we have observed some cytologic (and histologic) features that we think are distinctive in thymic squamous carcinoma.
