title: Calcification of eccrine poroma.
abstract: Two cases of eccrine poroma with calcification were described, both of which were those of the Winkelmann-MacLeod type. They occurred on the face and lower leg. We supposed that calcification in both cases was dystrophic in nature due to minor pressure or injury. The feature of calcification within the nests of eccrine poroma has rarely been reported. However, it seemed to be physiologically consistant that calcification occurs in eccrine poroma which originates from eccrine sweat glands.
