Kikuchi-Fujimoto disease (KFD) is cytologically characterized by a polymorphous lymphoid cell population, abundant karyorrhectic debris and histiocytes, many of which are crescentic (Kikuchi histiocytes). As per reviewed literature, KFD may be confused with tuberculosis, lymphoma, and reactive hyperplasia of lymph nodes (RHLN). Since RHLN was found to be a major challenging factor during routine cytodiagnosis of KFD in our material, we tried to find out the differentiating clinico-cytologic features between 76 KFD and 684 RHLN cases seen in Kuwait.

It is commonly believed that cytodiagnosis of Hodgkin's lymphoma (HL) is much easier than that of non-Hodgkin lymphoma (NHL). However, recognition of certain NHL subtypes with Reed-Sternberg (R-S)-like cells and results of immunohistochemical studies point to the contrary. To study the limitations of cytology in diagnosis of HL, fine-needle aspiration (FNA) smears of 130 lymphoma or suspected lymphoma cases were reviewed.

Psammoma bodies (PBs) form an important diagnostic criterion of papillary thyroid carcinoma (PTC), but their mechanism of formation is not clear. Following our observation in a case of PTC that laminated hyaline globules may be the precursor form of PBs, the present study was undertaken to find out their relation to PBs in PTC cases. Fifty-four cases of PTC and 14 follicular neoplasms, diagnosed by fine-needle aspiration (FNA) cytology, were studied by one of the investigators (DKD) to find out the PBs, irregular calcifications, hyaline globules, and other forms made of similar material.
