DEMODEX FOLLICULITIS ON THE TRUNK OF A PATIENT WITH MYCOSIS-FUNGOIDES

A 43-year-old man with tumour stage mycosis fungoides developed multip le follicular pustules on the trunk during total-skin electron beam th erapy. A potassium hydroxide preparation of the contents of the pustul es revealed the presence of Demodex mites. The patient was treated wit h 6% sulphur lotion with rapid improvement of the cutaneous lesions. W e believe that this case represents a pustular folliculitis caused by Demodex mites. Immunosuppression associated with mycosis fungoides and its treatment may have resulted in the proliferation of this obligate parasite of the pilosebaceous follicle, and the development of the fo lliculitis.
