Question: Can you identify this condition?

A 7-year-old boy presented with an asymptomatic skin-coloured to yellowish, soft to semifirm, slightly cystic dermal plaque, 2 to 3 cm in diameter, on the left temporal, somatic aspect of the scalp, which had been there since birth. A minute dimple was noted within the plaque. There was no history of any preceding perinatal trauma. The patient was healthy and taking no drugs. His family history was noncontributory.

The most likely diagnosis is

1. Epidermal inclusion cyst

2. Dermoid cyst

3. Nevus sebaceus

4. Meningoencephalocele
