Case report: Infectious mononucleosis in a 41-year-old man.
Postgraduate Medicine
|February 1, 1978
Summary
Infectious mononucleosis is often missed in adults. This case highlights rare symptoms like jaundice and pneumonitis, along with severe thrombocytopenia, in an adult patient.
Area of Science:
- Internal Medicine
- Infectious Diseases
- Hematology
Background:
- Infectious mononucleosis (IM) is typically diagnosed in adolescents and young adults.
- Diagnosis in older adults can be challenging due to atypical presentations.
Observation:
- A 41-year-old man presented with symptoms uncommon in infectious mononucleosis.
- Observed symptoms included arthralgia, epistaxis, jaundice, skin rash, and pneumonitis.
- The patient exhibited a markedly depressed platelet count.
Findings:
- The case demonstrates a rare presentation of infectious mononucleosis in an adult.
- Key atypical findings were arthralgia, epistaxis, jaundice, rash, pneumonitis, and severe thrombocytopenia.
- These symptoms collectively occur in less than 10% of IM cases.
Implications:
- Highlights the importance of considering infectious mononucleosis in adult patients with unusual symptoms.
- Suggests that severe thrombocytopenia can be a significant indicator of IM in older age groups.
- Emphasizes the need for broader diagnostic considerations for infectious mononucleosis beyond typical demographics.
