Question: Can you identify this condition?

A 32-year-old woman from the Philippines presents with an 18-month history of a slowly enlarging, red, scaly, annular plaque with numbness on her right elbow. She has already been seen by a number of physicians who have advised her to use cold or warm compresses, neither of which have had any effect. On one occasion she burned herself with a too-hot compress because she had diminished sensation over the area. She is healthy and not taking any medications.

The most likely diagnosis is

1. Nummular eczema

2. Sarcoidosis

3. Tuberculoid leprosy

4. Tinea versicolor

5. Granuloma multiforme
