Primary cutaneous follicle center lymphoma (PCFCL) is a neoplasm with differentiation of centrocytes and centroblasts presenting in the skin. At the time of initial manifestation, extracutaneous involvement is absent. PCFCL is considered as an indolent variant of primary cutaneous B-cell lymphomas since dissemination to extracutaneous sites is rare and the prognosis is favorable. Here we describe a 30-year-old man who was diagnosed with a cutaneous FCL and did not show extracutaneous affection at the time of occurrence. Six months later, however, he developed a diffuse large B-cell non-Hodgkin lymphoma localized in several lymph nodes of the neck that most likely reflects the occurrence of a second primary tumor in the same patient.
