HETEROTOPIC HAIRS IN THE TONGUE OF 2 DOGS

The occurrence of hairs in the median sulcus of the tongue in two dogs , a 7-year-old Rottweiler and a 10-year-old Cocker spaniel, is reporte d as an incidental observation at necropsy. The gross pathology of bot h cases and the histological and scanning electron microscopical findi ngs in one case indicated a heterotopic development of the hairs, with secondary inflammation. The term Pili heterotopici mediani linguae is suggested. (C) 1997 W.B. Saunders Company Limited.
