Coexisting follicular mucinosis and mycosis fungoides--a case report.

This is a case report of a patient with mycosis fungoides coexisting with follicular mucinosis. The simultaneous occurrence of these two conditions has been documented. There is controversy as to whether mycosis fungoides in patients with follicular mucinosis arises de novo or whether follicular mucinosis can evolve into mycosis fungoides. The relationship between the two conditions is discussed.
