A 74-year-old woman with a history of hypertension, stroke, and arthrosis presented with skin lesions around a scar on her right knee that appeared a few months after a prosthesis was implanted. The physical examination revealed annular lesions between 5 and 15 mm, with erythematous borders and skin-colored or hypopigmented central areas. They were located around the scar (Fig 1), but there were similar isolated lesions in both axillae (Fig 2) and the left groin. The fungal culture and patch tests were negative. The histopathologic results of the biopsy specimen are shown in Fig 3. 1.
What is the most likely diagnosis? A. Sarcoidosis B. Granuloma annulare C. Annular lichen planus D. Erythema annulare centrifugum E. Tinea corporis
2.
