Mycosis fungoides in Puerto Rico

Mycosis fungoides (MF) and Sezary syndrome compromise about 53% of cutaneous lymphomas. Disease stage depends on involved body surface area, clinical presentation and the presence or absence systemic involvement, which will determine treatment. MF is generally diagnosed at early stages and carries a chronic and indolent disease course. In 2007, 30 MF cases in Puerto Rico were described from 1983 to 2002. We performed a retrospective chart review of MF cases (1999-2016) to compare these populations and identify any changes in disease prognosis and treatment response given different and new treatment modalities are now available.
