Lymphocytoma cutis reflects an exaggerated local immunologic reaction to a stimulus presenting on the head, neck, or upper extremities as a firm 1-3 cm erythematous and/or violaceous plaque or nodule. However, lymphocytoma cutis may be difficult to treat due to the variety of causative agents and the lack of reported successful treatments and outcomes. Here, we present a case of 68-year-old female with recalcitrant lymphocytoma cutis resistant to other first-line therapies including tacrolimus ointment and steroids. The red plaque on the patient's left cheek was eventually treated with mycophenolate mofetil. Mycophenolate mofetil was an accessible and effective therapeutic option to treat lymphocytoma cutis with minimal side effects.

Reactive B-cell rich lymphoid proliferation (rB-LP), once called pseudolymphoma, is a benign lymphoproliferative disorder, which is histologically characterized by dense dermal infiltrate forming reactive germinal centers with tingible body macrophages. The disease frequently involves the face, scalp, and ear lobes. Treatment includes topical or intralesional steroids, surgical resection, ultraviolet therapy, laser treatment, and radiation therapy.

Cutaneous pseudolymphoma refers to a group of skin conditions that simulate lymphoma either clinically and/or histologically. Cutaneous pseudolymphoma is a benign disorder that can often be misdiagnosed and has a wide range of treatment modalities. Currently, there is no gold standard of treatment, and the literature would benefit from more reports on successful and unsuccessful treatments of cutaneous pseudolymphoma.
