Dermclinic—Answer

Case 3: Milium

Milia, D, are keratinaceous cysts that are common in children and middle-aged women. Primary milia, as seen in this patient, develop without any predisposing factors, whereas trauma is the most common cause of secondary milia. Simple excision and drainage is effective treatment.

Bacterial and fungal infections do not manifest as asymptomatic, solitary lesions that last for months. Molluscum have an umbilicated center. Milia arise on the surface of the skin, whereas epidermoid cysts are subcutaneous lesions.
