trichoepithelioma

 [trik″o-ep″ĭ-the´leo´-mah]
a benign skin tumor originating in the follicles of the lanugo; it may occur as an inherited condition marked by multiple tumors (trichoepithelioma papillosum multiplex). Called also epithelioma adenoides cysticum.

trichoepithelioma (trik´ōep´ithē´lēō´mə),

n a benign skin tumor arising from the epithelium or hair follicles. See also epithelioma adenoides cysticum.
Trichuris
n a genus of parasitic roundworms that infect the intestinal tract. Adult worms are 30 to 50 mm long and resemble whips with a threadlike anterior and a thicker posterior. Also called

trichoepithelioma

a benign skin tumor originating in the keratinocytes of the hair follicle outer sheath or the hair matrix. It occurs as single or sometimes multiple, firm, rounded skin nodules that may ulcerate. They are common in dogs, particularly Cocker spaniels. Called also epithelioma adenoides cysticum.
