Poromahttps://en.wikipedia.org/wiki/Poroma
Poroma is a benign skin tumor derived from sweat glands. They are most commonly found on acral distribution (on palms and soles), and most commonly in adults.

They are 1 ~ 2 cm, pink or red shiny tumorous lesions. A biopsy is sometimes done because it can look similar to squamous cell carcinoma.
