Second primary nonlymphoid malignancies (SPNLM) have long been recognized as a complication of chronic lymphocytic leukemia (CLL). A search was made of our cytopathology database for cases of CLL that also contained a SPNLM. Seventeen cases from 13 known CLL patients [M:F = 2.3:1; age range: 47-77 years, x = 67 years] met criteria for this study. SPNLMs consisted of different forms of metastatic carcinoma (10 patients) and malignant melanoma (3). Of 16 FNA biopsies and 1 pleural fluid, 82% had ancillary testing; 35% had the specimen subdivided for both flow cytometry (FCM) and immunohistochemistry (IHC). Lymph node was the most common site for FNA biopsy (12), followed by face (2), and soft tissue (2). Squamous cell carcinoma was the most common SPNLM (6), followed by melanoma (3), and there were single cases of adenocarcinoma, large cell neuroendocrine carcinoma, Merkel cell carcinoma, and papillary thyroid carcinoma. A correct specific cytologic diagnosis was made in 15 (88%) cases. Cytopathology is highly proficient in recognizing SPNLM in CLL patients. Utilization of cytologic material for FCM and IHC is feasible, and extremely helpful in achieving diagnostic accuracy. • Patients with CLL are known to have an increased risk of a second primary nonlymphoid malignancy (SPNLM). This risk appears to be increasing in recent years. • Most SPNLMs in CLL patients were carcinomas. • An accurate cytologic diagnosis of CLL plus a SPNLM was made in almost 90% of our patients. • Using cytologic material for both immunohistochemistry and flow cytometry on the same specimen is feasible, and helpful in achieving diagnostic accuracy.
