Pagetoid reticulosis is a rare form of cutaneous T cell lymphoma, a malignancy of T lymphocytes, that invades the skin leading to a multitude of dermatologic manifestations. Pagetoid reticulosis commonly presents as a localized slow-growing or indolently manifesting hyperkeratotic patch/plaque on the extremities that is confined to the epidermis. Diagnosis is confirmed via a skin biopsy of the affected area followed by a cytologic examination. Treatment typically entails topical corticosteroids, alkylating agents, and retinoids. With disseminated disease, a multidisciplinary approach involving chemotherapy and radiation is necessary. To raise awareness about pagetoid reticulosis, its diagnosis, and management, we report a case localized to the left forehead and earlobe of a 57-year-old female.
