“…Due to this presentation, HP is typically defined as a disease of early infancy and is very exceptional after the first year of life [10]. Only 5 adult cases have been reported up to now, the oldest being 71 years [4,11]. We believe that our case is the 6 th adult HP and also the 2 nd oldest one so far.…”

“…HPs are usually isolated but can be seen in association with a number of congenital malformations including cleft palate, uvula and external ear agenesis, ankyloglossia, choanal atresia, facial hemihypertrophy, left carotid artery atresia, osteopetrosis [1,6,14], persistent nasopharyngeal membrane, 1st & 2nd branchial arch malformations, etc. and are therefore, considered as a developmental abnormality [6,13,15]. One of the cases in our series was associated with congenital abnormality i.e.…”

“…Some authors designate HP as choristoma due to the presence of normal tissue in aberrant location [17,18]. The term ''teratoid tumors'' used for these lesions, is a misnomer as teratoid is defined as bi-trigerminal lesion with less differentiated components, which is not observed in hairy polyps [15]. In our opinion, these lesions represent developmental abnormalities and malformations which arise during fetal period.…”

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.
