Abstract
Background
Primary toxoplasmosis is frequently asymptomatic in immunocompetent adults. To our knowledge, a cluster of primary toxoplasmosis in Thailand has not been previously reported.
Objectives
To report a cluster of primary toxoplasmosis in a Thai family.
Methods
Physical examination, complete blood count, liver function tests, blood chemistry, chest radiography, and lymph node histopathology.
Results
A previously healthy 39-year-old man presented with painless bilateral cervical lymphadenopathy for one month. Simultaneously, his 6-year-old son had painless cervical lymphadenopathy. Lymph node histopathology of the man showed the classic triad of characteristics of toxoplasmic lymphadenitis. Both patients were doing well when last seen two months after symptomatic and supportive treatment.
Conclusions
Patients with toxoplasmic lymphadenitis can survive without specific antiparasitic treatment. Normal hosts may have a benign clinical presentation.
