Insights
A rare congenital hairy polyp was successfully removed from a four-month-old infant presenting with feeding and breathing issues. This case highlights the diagnostic utility of patient-recorded smartphone videos in identifying rare head and neck masses.
Area of Science:
- Congenital malformations
- Otolaryngology
- Pediatric surgery
Background:
- Hairy polyps are rare congenital growths originating from two germ cell layers (ectoderm and mesoderm).
- These growths typically occur in the head and neck region, primarily the nasopharynx and oropharynx.
Observation:
- A four-month-old infant presented with significant breathing and feeding difficulties.
- A smartphone video captured by the mother revealed a mass protruding from the infant's mouth, aiding diagnosis.
- Laryngoscopy identified the mass originating from the left posterior tonsillar pillar.
Findings:
- Surgical transoral removal of the mass was performed without complications.
- Pathological examination confirmed the mass as a skin-covered pedunculated hairy polyp.
- The infant experienced an unremarkable recovery and follow-up.
Implications:
- This report details a rare instance of a hairy polyp originating from the tonsillar pillar.
- It underscores the increasing role of patient-generated media, such as smartphone videos, in clinical diagnosis and management.
- Highlights the importance of considering rare congenital anomalies in infants with respiratory and feeding problems.
Background:
Hairy polyps are rare congenital growths of the head and neck, mainly found in the nasopharynx and oropharynx. They are made up of two germ cell layers: the ectoderm and mesoderm.
Methods:
This paper reports a four-month-old who presented with breathing and feeding difficulties. Clinical examination was unremarkable, but a video taken by the patient's mother on her smartphone showed a mass protruding from the infant's mouth. Laryngoscopy performed in the operating theatre showed that the mass emanated from the left posterior tonsillar pillar.
Results:
The mass was removed transorally with no complications. Pathological examination showed a skin-covered pedunculated structure characteristic of a hairy polyp. The patient's follow up was unremarkable.
Conclusion:
To the best of our knowledge, this is the second English-language case report of a patient with a hairy polyp emanating from a posterior tonsillar pillar. This paper also highlights the growing usage of smartphones by patients to help physicians with their diagnosis and management.

Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
