Diagnostics (Basel) 2023; 13:diagnostics13071328. [PMID: 37046546 PMCID: PMC10093516 DOI: 10.3390/diagnostics13071328] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 02/16/2023] [Accepted: 03/27/2023] [Indexed: 04/05/2023] Open
Abstract
Background: The typical imaging findings of hairy polyps have been described mostly in case reports. This study was conducted to describe the CT and MRI features of hairy polyps and their common associated abnormalities. Methods: Medical records of 14 patients with pathological diagnosis of hairy polyps were collected for this study. For each patient, the medical records, including demographics, clinical manifestations, and imaging findings were reviewed. Results: The female-to-male ratio was 3.7:1. The age at first episode varied from birth to 2.7 years. The masses were derived from the back side of the soft palate in seven (50.0%) cases, from the lateral pharyngeal wall in four (28.6%) cases, from the soft palate in one (7.1%) case, from the nasal vestibule in one (7.1%) case, and from the parapharyngeal space in one (7.1%) case. A total of 11 (78.6%) cases presented with pedicled masses containing fat and a central core of soft tissue, there were 3 (21.4%) cases whose imaging findings were atypical, and there were 6 (42.9%) patients who had other pathologies. Conclusions: Hairy polyps typically presented as pedicled masses containing fat and a central core of soft tissue, but sometimes their imaging findings can be atypical and they can be associated with other congenital abnormalities. CT and MRI are reliable methods for the diagnosis of hairy polyps and their associated abnormalities.

Naso-oropharyngeal choristoma (hairy polyps): an overview and current update on presentation, management, origin and related controversies. Eur Arch Otorhinolaryngol 2014; 272:1047-59.

Abstract
This review presents a comprehensive and updated overview of bigerminal choristomas (hairy polyps) of naso-oropharynx/oral cavity, and discusses the controversies related to nosology and origin from a clinico-embryologic perspective. English-language texts of the last 25 years (January 1989-January 2014) were collected from the PubMed/MEDLINE database using the given keywords. Of the 330 records, 64 full-text articles (mostly case reports/series) were selected, incorporating clinical data from 78 patients, after screening through duplicates and the given exclusion criteria. With the available evidence, hairy polyps appear more common than generally believed, and are increasingly being recognized as an important, often-missed cause of respiratory distress and feeding difficulty in neonates and infants. Such a child without any apparent cause should be examined with flexible nasopharyngoscope to specifically look for hairy polyps which might be life-threatening, especially when small. The female preponderance as believed today has been found to be an overestimation in this review. These lesions are characteristically composed of mature ectodermal and mesodermal tissue derivatives presenting as heterotopic masses, hence termed choristoma. However, little is known about their origin, and whether they are developmental malformations or primitive teratomas is debatable. Involvement of Eustachian tube and tonsils as predominant subsites and the speculated molecular embryogenesis link hairy polyps to the development of the first and second pharyngeal arches. They are exceptionally rare in adults, but form a distinct entity in this age-group and could be explained as delayed pluripotent cell morphogenesis or focal neoplastic malformations, keeping with the present-day understandings of the expanded "teratoma family".

Abstract
Hairy polyp is an unusual developmental malformation that is most frequently seen as a pedunculated tumor in the neonate. They are benign lesions containing elements of both ectodermal and mesodermal origin. The symptoms of hairy polyps relate both to their location and their size. Larger lesions produce symptoms due to feeding difficulties and airway obstruction while smaller lesions cause intermittent symptoms resulting from a ball-valve type of obstruction. We present two cases of a soft palate hairy polyp causing respiratory and feeding difficulties and review the literature.

Abstract
Hairy polyps are rare benign tumors that are derived from 2 germ layers: ectoderm and mesoderm. Although location in the head and neck area is rare, the soft palate as the site of origin is even more unusual. The clinical presentation depends on the polyp's location and size. These masses can commonly cause respiratory and feeding difficulties. We present a case of a soft palate hairy polyp causing respiratory and feeding difficulties in a 6-month-old female infant and review the literature.
