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.

Pain and anxiety management during pediatric dermatological procedures is a crucial aspect of medical care. Skin biopsies can cause stress and discomfort in children, negatively impacting the relationship between health care providers, patients, and caregivers. This study describes a local anesthesia protocol based on non-pharmacological techniques, consisting of prior explanation, parental support, visual distraction, and the use of cold or vibration before pharmacological anesthesia. Implementing this protocol may reduce pain and anxiety perception while offering a low-cost, low-tech, and safe care option.
