Lymphomatoid Papulosis Developing in an Mycosis Fungoides Lesion after Narrow Band UVB Phototherapy and Topical Corticosteroid Application / 대한피부과학회지

ABSTRACT

Patients with lymphomatoid papulosis have other lymphomas in 10~20% of cases, most commonly mycosis fungoides, Hodgkin's disease, and anaplastic large cell lymphoma. In a series involving at least 40 patients with lymphomatoid papulosis, the association of lymphomatoid papulosis with mycosis fungoides ranged from approximately 7% to 18%. It is most important to distinguish lymphomatoid papulosis from CD30-positive large cell transformation of mycosis fungoides. Both conditions can be distinguished on clinical grounds, and clinical course is often the only distinguishing feature. We report a case of lymphomatoid papulosis developing in an mycosis fungoides lesion in a patient who received 3 rounds of narrow band UVB phototherapy and topical corticosteroid application.
