Kuttner tumor is a relatively uncommon benign tumor-like lesion of the salivary gland that clinically mimics neoplasm because of its presentation as a hard mass. It is also known as chronic sclerosing sialadenitis or cirrhosis of the submandibular gland. We present here the aspiration cytological findings of a case of Kuttner tumor in a 58-year old woman. The aspiration specimen of this lesion showed numerous lymphoid cells that were similar to lymph node aspirates, with several scattered benign ductal cells and eosinophilic fibrous tissue. The lymphoid cells were composed of mature bland lymphocytes and follicular center cells. Any acinar cells were not identified. The excised mass was ill-demarcated, hard and fibrotic, and it histologically exhibited an intense lymphocytic infiltration with irregular lymphoid follicle formation, dense periductal and stromal sclerosis, and loss of acini. No evidence of neoplasm or sialolithiasis was discovered, and this led to the diagnosis of Kuttner tumor.
