FNAC in a case of NHL presenting initially as nodal infarction.

ABSTRACT

Lymph node infarction is rare and can occur in either nonneoplastic or neoplastic conditions. Fine needle aspiration cytology (FNAC) of infarction preceding lymphoma has not been described earlier. A 26-year-old male, was referred to the cytology laboratory for FNAC of bilateral axillary lymph nodes. FNA smears showed uniform looking ghost cells. There were no viable cells. A biopsy was advised which also showed extensive coagulative necrosis. Five weeks later, right cervical lymph nodes also appeared and FNA smears showed discrete monomorphic population of immature lymphoid cells. A cytologic diagnosis of infarction in a case of non-Hodgkin's lymphoma (NHL) was made and subsequently confirmed by histopathologic examination. Our case indicates that such cases should be followed up closely and repeated aspirations should be done to prevent a delayed diagnosis of lymphoma.
