Fine Needle Aspiration Cytology of Amyloid Tumor Arising in Association with Multiple Myeloma

다발성 골수종 환자에서 발생한 아밀로이드종의 세침흡인 세포학적 소견

Amyloid tumor is a tumorlike localized deposit of amyloid which is encountered occasionally in association with multiple myeloma and various chronic inflammatory diseases. This report describes a case of solitary amyloid tumor of the neck which was the presenting symptom arising in association with multiple myeloma. A 56-year-old woman complained of a palpable neck mass and fine needle aspiration was done. Multiple myeloma was diagnosed on the basis of the bone marrow biopsy and monoclonality of kappa light chain. The histologic and cytologic features of the amyloid appear to be characteristic and may allow a definitive diagnosis to be made on needle aspiration biopsy.
