“…HPs present as skin covered polypoidal masses which can arise from nasopharynx or oropharynx but are also reported to arise from a number of surrounding structures including soft palate [2,4,13], hard palate [5], tonsils [6][7][8], eustacheantube [9], middle ear cavity [10] and tongue [11]. The polyps in our series show diverse distribution, two of them were located in nasopharynx, one in soft and hard palate and one in lower lip.…”

“…HP can arise from any of the naso-oropharyngeal structures (including tonsils, eustachean tube and tongue) as a skin covered polypoidal mass [2][3][4][5][6][7][8][9][10][11]. Owing to its bi-germinal layer origin, it is characterized by skin (ectoderm) covering a (mesodermal) core of adipocytes, smooth muscle and cartilage [12].…”

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.

Cartilaginous choristomas occur in abnormal sites that usually do not contain chondrocytes. These lesions are very rarely seen in the soft palate. We present a 38 year-old patient with cartilaginous choristoma located in nasopharyngeal surface of soft palate. Histopathological examination demonstrated a well demarcated mature hyaline cartilage tissue which was surrounded with seromucous salivary glands under a benign respiratory epithelium.
