Immune-related cutaneous adverse events (irAEs) associated with checkpoint blockade agents are well described in the literature, and the lichenoid pattern is a commonly observed histologic subtype of irAEs. Clinically, lesions may resemble classic lichen planus and are typically distributed on the trunk and extremities. Herein, we present a case of lichen planus follicularis tumidus (LPFT), a rare variant of lichen planus, appearing as erythematous cystic papules on the cheeks of a patient receiving adjuvant anti-PD-1 (programmed cell death 1) therapy for melanoma.
