Are epidermal inclusion cysts painful?

Epidermal inclusion cysts are often asymptomatic. However as the keratin accumulates within the cyst, the cyst may increase in size, become sore or painful, and eventually rupture, leading to the drainage a foul-smelling, white to yellow “cheese-like” material. See your healthcare provider if you develop these or other concerning symptoms.
