A 13-year-old girl went to her physician because of sore throat, a 1-week history of general malaise, and fever. She also complained of some nausea and difficulty in drinking fluids. Physical examination revealed bilateral, enlarged, firm cervical lymph nodes, mild splenomegaly, and hepatomegaly.
The laboratory data revealed a WBC count of 15.0 x 109/L; a hematocrit, 42%; and reticulocyte count, 2.0%. a differential count of the peripheral blood revealed 65% lymphocytes, 25% granulocytes, and 10% monocytes. The differential report noted that 36% of the lymphocytes were reactive. Chemistry results showed that liver enzymes and bilirubin levels were slightly increased. No other abnormalities were noted.
After physical examination, additional laboratory work was ordered. The throat culture for streptococci was negative. A Monospot test was positive. No further laboratory work was ordered. After a few days of rest at home, the patient was allowed to return to school. No further problems were noted.
