We report a case of 18-year-old female patient who came to ENT OPD with history of right sided slowly progressing neck swelling since 6-8 months. There was no history of fever or weight loss except mild fatigue. On examination firm, ovoid, non tender and mobile mass measuring 4 × 2 × 5 cm was situated in the right side of the neck. ENT examination and other systemic examinations revealed normal findings. Fine needle aspiration cytology (FNAC) showed moderate cellularity comprising of small lymphocytes in dys-cohesive and in small clusters. These clusters are composed of follicular dendritic cells and occasional spindle ells. These follicular dendritic cells have oval nuclei, evenly distributed chromatin, small nucleoli with abundant delicate cytoplasm containing small lymphocytes along with few plasmacytoid cells. Computed tomography showed intensely homogeneously enhancing well defined lesion located postero-medially to the sternocleidomastoid and postero-laterally to the carotid vessels in the mid portion of the neck (probably carotid space) on right side. USG abdomen and X-Ray chest were done to rule out multicentric type of disease. Hence, diagnosis of Castleman's disease was made by FNAC of the mass and CT scan of the neck [Table/ Fig-1].Ear,Nose and Throat Section
