Watch the Tongue.

Answer: D A 35-year-old male newly diagnosed with human immunodefi ciency virus (HIV) infection (last negative test was 1.5 years ago) presented with an odd sensation on his tongue for a day without any dysgeusia. This was the fi rst time he had experienced this. He received treatment for presumed tinea infection over his palms and soles a month ago. On examination, shallow, slimy erosions were noted over the left lateral border of the tongue (Fig. 1). There was no palpable cervical lymphadenopathy. Hyperpigmented papulosquamous patches were present over bilateral palmoplantar surfaces. The rest of the physical examination was unremarkable.
