Objective: To describe the patient population with mycosis fungoides (MF) in Puerto Rico in terms of demographics, disease course, and management. Methods: We performed a retrospective chart review of patients with MF who were being followed at the University of Puerto Rico dermatology clinics from 1999 through 2016. Collected data included demographics, age at diagnosis, stage at diagnosis, follow-up time, treatment, and stage at the time of the study. Results: A total of 53 patients were diagnosed with MF from 1999 through 2016, with a mean follow-up period of 89 months. Of those, 45% were male. At the time of diagnosis, 40% were at stage 1A, 53% were at stage 1B, and 7% were at stages 2 to 4. During data collection, 74% of the patients remained stable, 18% improved clinically, and 8% progressed in disease stage. The treatment modalities used included phototherapy, topical steroids, topical and systemic retinoids, methotrexate, topical and systemic chemotherapy, and interferon. Conclusion: Our study reflects the chronic and indolent course of MF, which has an overall good prognosis if diagnosed at an early stage, as has been demonstrated in the recent literature. The information contained within this manuscript should contribute to the understanding and characterization of MF in patients in Puerto Rico.
