[Acute toxoplasmosis in coexistent non-Hodgkin lymphoma].
There are many reasons for cervical lymph node enlargement. In particular, the large group of infectious diseases must be considered along with malignant diseases. The coexistence of an uncommon infectious disease with malignant disease is a rare event. We report the case of an otherwise healthy 69-year-old man with marked enlargement of his cervical lymph nodes. A diagnosis of a recent toxoplasmosis infection was made based on positive IgG and IgM toxoplasma titers and the results of fine-needle aspiration from a lymph node. Since the enlarged lymph nodes persisted for more than weeks, the lymph node was excised. Histological examination revealed a non-Hodgkin's lymphoma. IgM titers in toxoplasmosis can persist up to 1 year. In cases with rare infectious diseases like toxoplasmosis in immunocompromised patients, swollen lymph nodes that persist or grow should lead to the suspicion of additional disease. A diagnosis can be confirmed by removing a lymph node for histology.
