The assessment of lymphoproliferative disorders using fine-needle aspiration (FNA) cytology may be problematic particularly when organs other than lymph node are involved. In this report we have reviewed 26 consecutive FNA specimens from superficial extranodal sites which were reported as diagnostic or suggestive of malignant lymphoma. The aspirates were obtained from skin or subcutaneous tissue (ten cases), thyroid (five cases), salivary gland (five cases), breast (four cases), neck, and pharynx (one case each). Ancillary studies including immunocytochemistry, in situ hybridisation to detect immunoglobulin light chain mRNA expression, and polymerase chain reaction for analysis of immunoglobulin heavy chain gene rearrangement were performed in 20, 12, and 7 cases, respectively. Clinicopathologic correlation confirmed the diagnosis of lymphoma in 25/26 aspirates. Nine of the 14 patients whose initial presentation was with an extranodal mass were considered to have primary lymphomas of mucosa-associated lymphoid tissue (MALT) type. In contrast, ten of 11 patients with recurrent extranodal disease had primary nodal type lymphomas. There was one false-positive diagnosis, a neck mass misinterpreted cytologically as B-cell lymphoma which was ultimately shown to be a branchial cyst. FNA cytology supported by appropriate ancillary investigations provides accurate diagnosis in most cases of extranodal lymphoma.
