“…Histological and histochemical findings indicate that these tumors are composed of cells compa rable with the epithelial elements of the in traepidermal eccrine ducts [8]. The ultrastructural characteristics are similar to those of the cells of the outer sheath of the embry onal, intraepidermal eccrine sweat gland ex cretory ducts [6].…”

A histological study of 14 eccrine poromas in 14 different patients was conducted and the results correlated with the clinical data. Histologically, an eccrine poroma is an easily recognizable epithelial skin tumor. Three morphological variants can be identified: a benign, a premalignant or dysplastic, and an invasive, malignant form. These tumors hardly have a typical clinical appearance. Symptoms such as bleeding, pain and itching are suggestive of a possible malignant transformation. There seems to be a predilection for localization on the limbs and the head. Most of the lesions occur in patients above the age of 60. It is noteworthy that these tumors, at least those of the face, occur on actinically damaged areas.

“…3 Although it is considered a be¬ nign hamartoma, Freeman and Winkel¬ mann4 have recently reported two cases of basal cell epithelioma with eccrine differ¬ entiation in which features similar to those of syringoma were observed. Syringoma af¬ fects mainly females and frequently appears at adolescence.5 Clinically, small, skin-colored to yellowish papules are present over eye¬ lids, chest, and neck.…”
