Congenital eccrine poroma on the left temple

Eccrine poroma is a benign, rare cutaneous neoplasm that clinically represents as solitary, reddish and pink papule or nodule chiefly on the soles or sides of the feet. But it can occur anywhere wherever sweat glands are found. Eccrine poroma generally arises in the middle-aged and elderly people and do not usually exceed 20 mm in diameter. To the best our knowledge, no congenital cases of eccrine poroma have been reported in the Korean literature. We, herein, report a rare case of eccrine poroma arising on the left temple in a 45-year-old man since birth.
