Toxoplasmosis lymphadenopathy-A series of 8 cases diagnosed in a 2-year timeframe: Is it a needle in a haystack?

Toxoplasmosis is a zoonosis caused by Toxoplasma gondii, an obligate intracellular parasite. Clinical presentation of infection depends on the age and immune status of the patient. In immunocompetent patient, it may present as a non-specific lymphadenopathy and self- limiting illness. In contrast, in immunocompromised patients it can be a life-threatening infection. We present a series of 8 cases of toxoplasma lymphadenitis diagnosed in our institute in last two years. Lymphadenopathy raises a suspicion of malignancy; however, diagnosis of reactive lymphadenitis often marks the end of diagnostic evaluation. Careful morphological evaluation, the classic triad, often can direct at a conclusive diagnosis. We are presenting a case series to draw attention to this entity as majority of the published literature is in the form of case report and serological surveys and very occasional study showing both the histopathology and serology in tandem.
