Cutaneous T-cell lymphoma developing in surgical scars post cardiac surgery: A case study

Cutaneous T-cell lymphomas are a class of non-Hodgkin lymphomas characterized by the infiltration of malignant T cells into the skin. Their precise pathogenesis remains incompletely understood, but persistent and specific antigen stimulation of skin-homing CD4+ memory T cells by external or internal factors, combined with an inflammatory cytokine-rich tissue microenvironment, may be critical in the development of cutaneous T-cell lymphomas. We present herein a case of primary cutaneous T-cell lymphoma arising in two surgical scars that developed 6 months post-operatively and were successfully treated with external beam radiotherapy. This case highlights the notion that primary cutaneous T-cell lymphoma can develop locally at the site of injury/foreign body within a relatively short time post trauma/surgery. This work contributes to the literature of cutaneous T-cell lymphomas arising after a trauma, surgery, or a foreign body.

Automated summary

Cutaneous T-cell lymphomas are a type of non-Hodgkin lymphomas in which malignant T cells infiltrate the skin. The pathogenesis of these lymphomas is not completely understood, but persistent antigen stimulation of CD4+ memory T cells in the skin, combined with an inflammatory tissue environment rich in cytokines, may play a critical role. This case report demonstrates that primary cutaneous T-cell lymphoma can develop locally at the site of injury or surgery within a relatively short period of time. It contributes to the literature on cutaneous T-cell lymphomas arising after trauma, surgery, or a foreign body.
