Hairy polyp is an uncommon lesion of the nasopharynx and oropharynx. It is most frequently seen as a pedunculated mass at birth or in the first year of life. It generally has been classified as dermoid derived from the ectoderm and mesoderm. The symptoms depend on the size and location of the lesion. We report the clinico-pathological features of a hairy polyp arising from the right nasopharyngeal side of soft palate in a 21-day-old girl. Grossly, a well demarcated brownish yellow solid mass, measuring 2.7x1.5x1.2 cm, showed fine hairs on the surface. The cut surface was a yellowish brown solid appearance. Microscopically, it was covered with keratinizing squamous epithelium and was composed of mature adipose tissue, skeletal muscle, a few peripheral nerve bundles, and blood vessels in the center and mature pilosebaceous units in the periphery. Knowledge of this type of malformation facilitates early intervention and avoids significant morbidity.
