Summary
This study reports a rare case of cutaneous B-cell lymphoma (CBCL) presenting in a dermatome pattern with early lymph node spread. The presence of bcl-2 gene rearrangement suggests a potential role in its aggressive behavior.
Area of Science:
- Dermatology
- Oncology
- Molecular Biology
Background:
- Primary cutaneous B-cell lymphomas (CBCLs) are typically indolent skin cancers.
- A variant occurring on the legs exhibits a more aggressive clinical course.
Observation:
- A unique case of CBCL presented with a dermatome-like distribution.
- Early peripheral lymph node involvement was observed in this patient.
- Polymerase chain reaction detected bcl-2 gene rearrangement in skin samples.
Findings:
- The bcl-2 gene rearrangement, typically absent in classic CBCLs, was identified.
- This genetic alteration may correlate with the aggressive clinical behavior observed.
- The unusual dermatomal presentation remains unexplained, with viral etiology being speculative.
Implications:
- This case expands the known clinical presentations of CBCL.
- The bcl-2 rearrangement may serve as a biomarker for aggressive disease in CBCL.
- Further research is needed to elucidate the pathogenesis of dermatomal CBCL and the role of bcl-2.
