Eccrine Neoplasms – Poromas

Eccrine Poromas are benign eccrine neoplasms that I occasionally encounter in my The Woodlands dermatology and Conroe dermatology offices.  Eccrine Poromas have histological variants called Hidroacanthoma Simplex and Dermal Duct Tumors.  Eccrine Poromas are most often found on the soles of the feet and appear as a red/brown nodule that may be encased in a cup shaped depression.  Most Eccrine Poromas are solitary but there is a variant in which a patient may develop hundreds of lesions called Eccrine Poromatosis.  As Eccrine Poromas may develop malignant degeneration, it is recommended that they be completely surgically excised.
