Ki-1 Anaplastic Primary Cutaneous Large-cell Lymphoma

A 63-year-old woman presented with a large, subumbilical ulcerated nodule that was a Ki-1+ anaplastic large-cell lymphoma with exclusively cutaneous localization. This high-grade lymphoma, in this case, has a less severe prognosis. Surgical resection or local radiotherapy seems sufficient for the localized cutaneous forms.
