Eccrine porocarcinoma

“…Eccrine poroma is a fairly common cutaneous tumor, usually occurring as a solitary lesion (2). In approximately two‐thirds of cases, lesions occur on the soles or sides of the foot (18) with remainder occurring in order of decreasing frequency on the hands and fingers, but is rarely observed on the head, neck, and chest (19,20).…”

Benign eccrine poroma in the palm of the hand

“…Recurrence after incomplete excision has occurred in different regions of the body. 2 – 4 For this reason, patients should be followed up with close observation for possible recurrence and the development of new lesions in other areas of the body. Histologically proven transformation of cases from benign to malignant tumors in other parts of the body have been reported in the literature.…”

Eccrine Poroma

“…Both of our cases occurred in the classical location, but while the sole is apparently a site of predilection, instances of eccrine poroma occurring on the palm, chest, back, and calf have been reported.
