ABSTRACT The formation of a Hairy Polyp on the dorsum of the tongue is a rare condition that may hinder vital functions such as swallowing and breathing due to mechanical obstruction. The authors present the situation on a child with an approach of significant academic value.
Imaging diagnostics with the application of a topical oral radiocontrastant was used to determine the extent of the tumor. Performed treatment was complete excision and diagnostics was confirmed with anatomopathological analysis.
The patient was controlled for five months and, showing no signs of relapse, was considered free from the lesion.
Accurate diagnostics of such a lesion must be performed in depth so that proper surgical treatment may be performed. The imaging method proposed has permitted the visualization of the tumoral insertion and volume, as well as the comprehension of its threatening dynamics.

    ABSTRACT: Hairy polyps (HPs), dermoids or teratoid tumors are rare tumors of naso-oropharyngeal region which commonly present at or shortly after birth. The etiology and classification of these tumors is still debatable and categorized by different authors differently. HPs have female predominance and usually present with respiratory and feeding problems. Microscopically, the polyp is covered by skin with underlying mesenchymal core. The aim of this study is to describe the clinicopathological features of Hairy polyps on a cohort of cases. We reviewed the surgical pathology database of our institution for last 10 years and retrieved four cases of hairy polyps. The age of patients ranged from 1 month to 18 years (mean = 12 years), with a female to male ratio of 1:3. Two of our cases presented at birth and two cases in late teens. Two of the HPs were located in nasopharynx, one on soft and hard palate and one on lower lip. One case was associated with bifurcation of tongue. Size of the polyps ranged from 2.3 to 4.5 cm (mean = 3 cm). Histologically, all HPs were lined by skin and the underlying core consisted of adnexal structures, adipocytes, skeletal muscle, smooth muscle and seromucinous glands. Lymphoid aggregates, cartilage and bone were seen in one case each. Our series highlights the diverse nature of this entity in terms of age of presentation and location. HP at lower lip and associated bifurcation of tongue has not been previously reported. We observed a male predominance in contrast to the published literature. However, number of cases is too few to read a definite conclusion on this point. The etiology is still controversial and includes congenital malformation and activation of pluripotent stem cells.
