Five-cases report of pharyngeal hairy polyps in infant

Update From The 4th Edition of the World Health Organization Classification of Head and Neck Tumours: Nasopharynx.

The current WHO classification system for tumors of the head and neck has made few changes from the previous edition with regards to tumors of the nasopharynx. The classification system is discussed here with particular attention to nasopharyngeal carcinoma, nasopharyngeal papillary adenocarcinoma, salivary gland anlage tumor, hairy polyp, juvenile angiofibroma, and other tumors.

The clinical analysis and surgical management of infant nasopharyngeal neoplasms

Objective:To analysis the clinical features, diagnosis and treatment experience of nasopharyngeal neoplasm in infants.Method:Twenty infants cases of nasopharyngeal neoplasm, from June 2002 to March 2015, admitted in our department were retrospectively studied. Nasopharyngeal neoplasm in all cases were ablated with low temperature plasma radiofrequency ablation after anesthesia downlink preoperative 70 degrees endoscope, and new biological routine pathologic examination were done.Result:The low temperature plasma radiofrequency ablation has several advantages,such as simple and convenient operating, short operating time, intraoperative blood loss and clear vision.Five cases were diagnosed as postoperative pathological cyst,4 cases were teratoma, 4 cases were hairy polyps,3 cases were hamartoma, 2 cases were hyperplasia of lymphoid tissue, 1 case was glioma, and 1 case was rhabdomyosarcoma. Postoperative follow-up for 6 months to 12 years, recurrence were found in 2 cases, including 1 death case.Conclusion:Infants nasopharyngeal neoplasm are almost benign, clinical rare congenital nasopharyngeal tumor more than the early detection of an infant. CT and MRI examination has important significance to the diagnosis. Low temperature plasma radiofrequency ablation with Seventy degrees nasal endoscope is worth extending.

Adult nasopharyngeal hairy polyp presenting with middle ear effusion

ABSTRACT Inroduction: Hairy polyp is a relatively uncommon congenital mass mainly seen in naso-oropharynx. It has been also called as choristoma owing to its bigerminal composition and unexpected location. It is almost always seen at birth and in the early infancy period. Adult presentation is very exceptional and only 5 adult cases have been reported as far as we know. Case Presentation: We present a case of nasopharyngeal hairy polyp in a 69 year old woman admitted with hearing impairment due to middle ear effusion. We also review the relevant literature. The lesion was totally removed via combined naso-endoscopic and trans-oral approach. After 1 year of follow up there was no sign of recurrence neither in the endoscopic evaluation nor in the magnetic resonance imaging. Conclusion: Although nasopharyngeal hairy polyp frequently leads ear problems in the infancy period, the presented case is the 1’st adult hairy polyp case with middle ear effusion. Also it is the 2’nd oldest one so far.

Hairy Polyp in Nasal Vestibule

Hairy polyps are rare congenital benign masses of the head and neck. They mainly occur in the nasopharynx and oropharynx. This paper reports a 12-month-old female patient who had a 0.5-cm sausage-shaped mass in the left nasal vestibule with nasal obstruction and habitual nose-picking. This lesion was surgically removed with no complications under monitored anesthesia. There was no evidence of recurrence through 24 months. To the best our knowledge, this is the first English literature report of a patient with a hairy polyp arising from a nasal vestibule.

Naso-oropharyngeal choristoma (hairy polyps): an overview and current update on presentation, management, origin and related controversies.

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".

Intermittent Dyspnea and Cyanosis in a Newborn Caused by a Hairy Polyp

Hairy polyps were first described by Brown-Kelly1 in 1918. They are rare benign malformations of the oropharynx and nasopharynx comprising elements of ectodermal and mesodermal origins foreign to the sites in which they are found.2 Although rare, they have to be considered in children, especially in newborns, with intermittent dyspnea.

Hairy polyp of the nasopharynx, an unusual presentation, a case report and literature review

AbstractWe report a rare tumor of the nasopharynx with an unusual presentation in a 15-year-old female: the teratoid or hairy polyp. Hairy polyps are rare benign congenital tumors that present at birth or shortly after. Usually, they arise from the ectoderm and endoderm. Their presence in older individuals is unusual. Their clinical presentation depends on the site and size. Our patient presented late with nasal obstruction, snoring, and mouth breathing, and the clinical examination indicated a nasopharyngeal mass. The tumor was removed without complications and the histopathology was consistent with hairy polyp. In this short communication, we raised awareness of such a rarity of nasopharyngeal mass that has to be suspected in pediatric age group. A review of this unusual malformation will be included. We believe, after a computerized literature search, that this is the first report of its kind from the Arabian Peninsula.

Cleft Palate Associated with Hairy Polyp: A Case Report

Congenital tumors of the oral cavity are extremely uncommon, and hairy polyps are rare nonneoplastic growths. Most hairy polyps arise from the oronasopharynx and may cause impairment of the upper aerodigestive tract in newborns. Cleft palate is one of the most common congenital anomalies but its association with hairy polyp has been rarely reported. We report a case of hairy polyp with cleft palate and its management.

Hairy polyp can be lethal even when small in size

A case of sudden cardiopulmonary arrest in a 3-month-old girl is presented. The patient had barely recovered from hypoxic encephalopathy when she presented with repeated respiratory distress. Computed tomography and endoscopic analysis revealed a shiny polyp in the lateral wall of the nasopharynx, and this polyp was suspected to be the main cause of respiratory distress. After referral to our hospital, surgical removal was performed, and the histopathological diagnosis was hairy polyp. Hairy polyp is a rare congenital benign tumor that sometimes induces respiratory distress. This polyp can potentially induce a life-threatening event. In a systematic review of 40 reported cases, polyps of ≤ 3.0 cm in diameter have a higher risk of respiratory distress than do those >3.0 cm in diameter (P = 0.01). Small hairy polyps may be lethal because of delayed diagnosis. To locate small hairy polyps, physicians should not hesitate to perform further examination because there is the possibility of oversight with only physical examination.

Hairy Polyp, a Clinicopathologic Study of Four Cases

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 10years and retrieved four cases of hairy polyps. The age of patients ranged from 1month to 18years (mean=12years), 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 4.5cm (mean=3cm). 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.

Imaging of pediatric floor of mouth lesions

There is a vast spectrum of pathology that afflicts the floor of mouth in children. These span inflammatory conditions, vascular malformations, developmental anomalies, benign tumors and malignancies. While this area is readily evaluated on clinical exam, imaging is often performed to better characterize the disorder prior to management. The imaging modalities most frequently utilized are US, CT and MR. The purpose of this article is to describe the primary conditions that occur in this location in children so that radiologists may provide an appropriate differential diagnosis. These include ranula, venolymphatic malformation, dermoid, teratoma, foregut duplication cyst, hairy polyp, thyroglossal duct cyst and rhabdomyosarcoma. For each pathological condition, there will be a focus on describing its imaging manifestation. Floor of mouth anatomy, imaging approach during both prenatal and postnatal life and etiologies will be discussed. Surgical considerations and operative photographs will also be presented.

Caught on camera: hairy polyp of the posterior tonsillar pillar

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. 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. 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. 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.

Dermoid cysts of the Eustachian tube: A transnasal excision

Congenital dermoid cysts are benign developmental lesions and are a well-recognised entity in head and neck surgery. First reported in 1828 by Berger et al., these lesions have been referred to as dermoids, hairy polyps, teratoid tumours with varying classification systems. This has caused confusion in the medical literature with a lack of consensus regarding optimal diagnosis and management. Within the Eustachian tube, there have been 16 reported cases in the English literature demonstrating the rarity of these lesions. The aim of this report is to present a case of histopathologically confirmed Eustachian tube dermoid, confirm the current classification system and demonstrate the challenges they can pose given the relative inaccessibility of such lesions.

Congenital Hairy Polyp of the Palatopharyngeus Muscle

Purpose. To describe clinical, radiologic, and histological features of a congenital hairy polyp arising from the palatopharyngeus muscle in a neonate. Methods. Chart of a 2-day-old female referred to a tertiary care pediatric hospital for assessment of intraoral mass was reviewed. Results. The child was born at 32 weeks and an intraoral mass was noted. The patient was transferred to tertiary care children's hospital on day 2 of life. The child had increased work of breathing at presentation and required continuous positive airway pressure. Physical examination revealed a pedunculated mass which was protruding into the oropharynx from the nasopharynx. MRI of the lesion documented a discrete bilobed mass which filled the posterior nasopharynx. The mass abutted the uvula and soft palate; however, the mass did not appear to be arising from the soft palate. Intraoperative exam showed a mass arising from the right palatopharyngeus muscle in the superior pole region of the tonsil. Histologic examination showed ectodermal and mesodermal derivatives confirming congenital hairy polyp. At 8-month followup, the surgical site was healed with no evidence of recurrent lesion. Conclusions. Congenital hairy polyp, though uncommon, should be considered in the differential diagnosis of oropharyngeal mass in neonates.
