Primary cutaneous follicular center lymphoma of the upper arm: A case report

Primary cutaneous follicle center lymphoma (PCFCL) is unique in its biological behavior and molecular features, and it is also relatively rare. The present study reports a case of PCFCL in a young male patient, aged 32 years, whose primary skin lesion was located in the left upper arm. A skin biopsy confirmed that the dermal tissue of the patient's skin was affected by PCFCL. The patient was treated with radiation therapy and the mass was significantly reduced, with a resultant good prognosis. This case of a young patient with PCFCL is reported in order to provide a reference for the diagnostic segment of this disease.
