Abstract
- It has been generally assumed that eccrine poroma ariees from acroayringium, epidermal sweat duct unit. One of the characteriatics of thie structure is abaence of melanocytes and melanin granules among ite cells. Hmvever, a cornplete abeence of melanocytes and melanin granules in eccrine poroma is not invariable and a few reparts of such an occurrenee were presented, We report a case of eccrine poroma on the area below lateral malleolus af left foot. Microscpically melanin granules, confirmed by the use of Fontana Masson stain, were found in some of the tumor cells.
