Summary
This study reports a rare case of low-grade, peripheral T-cell lymphoma in a young man's testicle, initially presenting as a bacterial abscess. This finding is significant as such low-grade testicular lymphomas are previously undocumented.
Area of Science:
- Oncology
- Hematology
- Pathology
Background:
- Non-Hodgkin's lymphoma is a common testicular cancer in older men, typically intermediate- to high-grade.
- Primary testicular lymphomas are rare in younger individuals.
- Peripheral T-cell lymphomas of the testes are uncommon, predominantly large cell types.
Observation:
- A 30-year-old male presented with a scrotal abscess caused by Staphylococcus aureus.
- The abscess was found to be an unusual presentation of a primary small lymphocytic, CD4+, peripheral T-cell lymphoma.
- Southern analysis confirmed clonal rearrangement of the T-cell receptor beta gene.
Findings:
- The case represents a primary small lymphocytic, CD4+, peripheral T-cell lymphoma of the testis.
- This specific type of low-grade T-cell lymphoma in the testes has not been previously documented in medical literature.
- The lymphoma mimicked a bacterial scrotal abscess.
Implications:
- Highlights the importance of considering rare malignancies in young men presenting with seemingly common conditions like scrotal abscesses.
- Expands the known spectrum of testicular lymphomas.
- Suggests potential for misdiagnosis if low-grade T-cell lymphoma is not considered in the differential diagnosis.
