A rapidly enlarging nodule on the face

Primary cutaneous CD4+ small medium T-cell lymphoproliferative disorder (PCSM-TCLPD) is a rare, benign lymphoid proliferation that can clinically mimic malignant cutaneous neoplasms. This case report describes a rapidly enlarging, non-tender, pink nodule on the face of a 53-year-old female. Histopathology analysis revealed a diagnosis of PCSM-TCLPD. PCSM-TCLPD should be considered in the differential diagnosis of solitary facial nodules. Recognition of its characteristic dermoscopic and histopathological features can prevent unnecessary and aggressive treatment, as prognosis is excellent.
