증례보고 항암요법치료중인다발성골수종환자에서원심고리홍반으로발현한몸백선 1 예 = Abstract = 가톨릭대학교의과대학피부과학교실 김은정 김혜성 김형옥 박영민 A Case of Tinea Corporis Mimicking Erythema Annulare Centrifugum in a Patient Treated with Chemotherapy Due to Multiple Myeloma Eun Jung Kim, Hei-Sung Kim, Hyung-Ok Kim and Young-Min Park Department of Dermatology, Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Korea Tinea corporis usually presents as an erythematous annular plaque with a scaly, concentrically expanding border. However, it is often difficult to diagnose when the initial manifestation is atypical, especially in immunocompromised patients. Early accurate diagnosis on mycologic basis may be of value in controlling the disease and preventing severe infection. We herein report an atypical case of tinea corporis that presented with skin lesions resembling erythema annulare centrifugum. A 61-year-old female presented with multiple, pruritic, polycyclic plaques on the back for a few days. She had been diagnosed with multiple myeloma, and was being treated with Velcade chemotherapy. KOH examination was positive, and on histological examination, fungal hyphae were noted on Periodic acid-schiff (PAS) stain. Fungal cultures from skin scrapings showed growth of Trichophyton rubrum.
