Question: Can you identify this condition?

A 32-year-old man presented with 1-year history of multiple asymptomatic red lesions on his chest and upper back. Some of the lesions had resolved, with no residual scarring, but new lesions kept appearing over time. He did not have any associated constitutional or systemic symptoms. The patient was otherwise healthy and was not taking any medications. He did not have a family history of skin, rheumatologic, or autoimmune disorders. Skin examination revealed multiple indurated erythematous to violaceous papules and plaques, with no surface changes. Findings of the rest of the physical examination were normal.

The most likely diagnosis is

1. Pityriasis rosea

2. Guttate psoriasis

3. Tumid lupus erythematosus

4. Sarcoidosis
