| • | aka epidermal inclusion cyst |
| • | multiple EIC’s think of Gardner’s syndrome (prophylactic colectomy) |
| • | idiopathic scrotal calcinosis - probably represents previous epidermal inclusion cysts, which undergo dystrophic calcification |
vs. pilar cyst:
| • | EIC's typically occur anywhere on the body (except scalp where it is usually a pilar cyst) |
| • | thinner walled (and therefore harder to excise intact) than pilar cysts |
