Abstract
Spiradenocylindroma is a rare benign adnexal tumor with features of both spiradenoma and cylindroma, the scalp and face being the most common sites. They are considered to arise from pluripotent cells of abortive adnexal primordial tissue. Fine needle aspiration cytology, along with cell block, can give clues regarding the diagnosis. The final diagnosis is made on histopathology, which shows features of both cylindroma and spiradenoma in the same tumor. Multiple spiradenocylindromas can be associated with Brooke–Spiegler syndrome, where malignant transformation has also been reported. We report a case of spiradenocylindroma of the arm in a 50-year- old male and describe the clinical, cytologic, cell block, and histopathologic features.
期刊介绍：
Diagnostic Cytopathology is intended to provide a forum for the exchange of information in the field of cytopathology, with special emphasis on the practical, clinical aspects of the discipline. The editors invite original scientific articles, as well as special review articles, feature articles, and letters to the editor, from laboratory professionals engaged in the practice of cytopathology. Manuscripts are accepted for publication on the basis of scientific merit, practical significance, and suitability for publication in a journal dedicated to this discipline. Original articles can be considered only with the understanding that they have never been published before and that they have not been submitted for simultaneous review to another publication.
