Abstract
Primary cutaneous B-cell lymphomas are non-Hodgkin lymphomas presenting only in
the skin and represent 25% of all primary cutaneous lymphomas. Based on their
clinical behavior, they are classified into indolent and intermediate forms.
Treatment of indolent forms includes surgery, radiotherapy, and, in extensive
disease, rituximab. We report a case of a 57-year-old woman with a single nodule
in the left arm treated with surgical excision with 5-mm security margins,
without relapse after 36 months. Surgery is a therapeutic option in these
lymphomas without compromising disease-free survival.
