Breast and thyroid involvement in multiple myeloma: The cytological diagnosis and a rare case report

Abstract

Extra medullary involvement of multiple myeloma is a known phenomenon, but breast and thyroid are rarely involved. This patient presented in onco-surgery OPD with breast lump and thyroid enlargement. The diagnosis of multiple myeloma involving both organs was made in a retrograde fashion. FNAC played a key role in diagnosing this lesion. A thorough clinical, radiological evaluation, strong suspicion and immunohistochemistry helped confirm the diagnosis of multiple myeloma.
