Trichoblastoma is a slow-growing and well-circumscribed rare adnexal tumor. Although considered a benign neoplasm, there are cases of aggressive trichoblastomas. This paper reports a case of a 66-year-old female patient with a recurrent and continuously growing tumor in the right nasal wing that was treated with Mohs Micrographic Surgery.

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.
