Primary cutaneous CD4+ small/medium T-cell lymphoproliferative disorder nodule successfully treated with laser Co2 ablation: a case report and literature review

This case report describes an 83-year-old patient with a history of non-melanoma skin cancer who presented with a violaceous, painless nodule on the neck. Dermoscopic examination and subsequent biopsy revealed a Small/Medium CD4+ T-cell lymphoproliferative disorder (SMPLPD) of the skin. Although excision was initially recommended, the patient opted for treatment with CO2 laser ablation. The procedure had some minor complications but resulted in successful healing. SMPLPDs are a rare skin condition with limited treatment data, and this case suggests that CO2 laser ablation with minimal margins could be a viable alternative for selected patients, reducing bleeding and promoting second-intention healing for small nodules. However, more extensive followup data for SMPLPD cases are needed to understand long-term outcomes better.
