Hidradenoma papilliferum of the external auditory canal. Case report.

ABSTRACT:

Introduction

Hidradenoma papilliferum, also known as papillary hidradenoma, is a rare tumor of the sudoral glands, that occurs almost exclusively in women, on the vulvar and perineal region. Non-genital papillary hydradenoma is an even more rare occurrence, though some cases have been described in literature.This is a report of a 56 years old patient who presented with unilateral hearing loss secondary to a mass of the external auditory canal (EAC). A biopsy allowed us to make the diagnosis of a papillary hidradenoma of the EAC. The treatment was based on surgery; the tumor was removed while respecting the adjacent structures. Follow-up of the patient shows no actual recurrence.

Conclusion

Ectopic Hidradenoma papilliferum located in the EAC is a rare occurrence, and should be considered as a possible diagnosis when investigating a mass of the EAC.

Temporomandibular joint (TMJ) disorders as first clinical manifestations in external auditory canal cholesteatoma. A case report.

Project description:Introduction and importanceCholesteatoma is a common occurrence in the middle ear, whereas cholesteatoma of the external auditory canal (EAC) is a rare condition. We report an unusual presentation of the cholesteatoma in the EAC.Case presentationWe report a case of a 67-year-old male presented to the ENT casualty with a longstanding history of left sided squeaky type sound, aggravated whenever he talks or eats. He subsequently had a Computed Tomography (CT) scan of the left petrous bone which identified a left-sided EAC cholesteatoma. Clinical symptoms of EAC cholesteatoma are non-specific, and hence we recommend considering cholesteatoma when patients present with abnormal EAC symptoms and intact tympanic membrane.Clinical discussionHis cranial nerves examination was normal, and the tympanic membrane was intact. His blood count and infective marker were normal. The CT scan of the brain showed a lesion in the left external auditory canal close to the tympanic membrane. The lesion was in contact with the anterior inferior canal wall which had features suggesting bony erosion. Gas bubble seen in the posterior part of the TMJ was in relation to bony erosion of the EAC.ConclusionThe cholesteatoma of the EAC is very rare. CT scan can provide detailed information about the extent of external ear canal cholesteatoma, which can be used to identify complications of the disease, in addition to differentiating the external ear canal from the middle ear cholesteatoma. Early recognition of cholesteatoma and prompt treatment is essential to prevent catastrophic complications.

Internal auditory canal exostosis: A technical case report.

Project description:Background:Exostoses of the internal auditory canal is a rare finding that may present with disabling symptoms of dizziness, hearing loss, and vestibular dysfunction based on the extent of cranial nerve compression. The purpose of this case report is to discuss the presentation and outcomes in a patient who presented with this disorder. Case Description:A 19-year-old female presented to the neurotologist with left ear discomfort, pain with left lateral gaze, and dizziness. She underwent extensive evaluation including audiometric testing, videonystagmography, and neuroimaging, which confirmed left auditory and vestibular hypofunction and compression of the contents of the internal auditory canal from the exostosis. After extensive counseling, the patient elected to undergo a suboccipital craniectomy to remove the internal auditory canal exostosis. She experienced complete resolution of symptoms. Conclusions:Exostoses of the internal auditory canal, although rare, can present with severe symptoms of dizziness, hearing loss, and vestibular hypofunction based on the extent of cranial nerve compression. Imaging, particularly with thin-cut computed tomography, is invaluable in making the correct diagnosis. Severe cases can be treated successfully with surgery with minimal or no complications and excellent outcome.

Sialocutaneous fistula to the external auditory canal repaired with superficial parotidectomy and temporoparietal flap: A case report.

Project description:RationaleGustatory otorrhea can lead to cutaneous changes, recurrent infection, and social disruption. We present a case of a late, evolving sialocutaneous fistula to the external auditory canal, managed surgically after failing conservative therapies. This case is unique by late evolution, whereby the symptoms presented with significance 27 years after her operation and 19 years after mild symptoms initially arose.Patient concernsGustatory, left-sided clear otorrhea with acutely increased volume over 8 months causing social disruption.DiagnosesSialocutaneous fistula to the external auditory canal.InterventionsSuperficial parotidectomy and temporoparietal flap for closure of fistula.OutcomesNo postoperative complications and resolution of gustatory otorrhea at one-year follow-up.LessonsThis rare, but important, postoperative complication can present late with evolving symptoms, causing significant social disruption. It can be treated with conservative medical management and several surgical approaches.

Gene expression profile in external auditory canal squamous cell carcinoma

Project description:External auditory canal squamous cell carcinoma (EACC) is very rare, only accounting for two thousandth of the head and neck cancer. However, the development mechanism of EACC remains unknown. By using gene expression microarray analysis, we aimed to find differentially expressed genes involved in ESCC development. We identified a wide spectrum of molecular signatures in EACC, including mRNA and lncRNA. The present study systematically analyzed the expression of mRNA and lncRNA in squamous cell carcinoma of the external auditory canal and normal external auditory canal tissues. We detect the transcriptomic changes between squamous cell carcinoma of the external auditory canal and normal external auditory canal tissues to identify potential tumor biomarkers in squamous cell carcinoma of the external auditory canal.

Genetic landscape of external auditory canal squamous cell carcinoma.

Project description:External auditory canal squamous cell carcinoma (EACSCC) is an extremely rare and aggressive malignancy. Due to its rarity, the molecular and genetic characteristics of EACSCC have not yet been elucidated. To reveal the genetic alterations of EACSCC, we performed whole exome sequencing (WES) on 11 primary tumors, 1 relapsed tumor and 10 noncancerous tissues from 10 patients with EACSCC, including 1 with a rare case of synchronous bilateral EACSCC of both ears. WES of the primary tumor samples showed that the most frequently mutated gene is TP53 (63.6%). In addition, recurrent mutations in CDKN2A, NOTCH1, NOTCH2, FAT1 and FAT3 were detected in multiple samples. The mutational signature analysis of primary tumors indicated that the mutational processes associated with the activation of apolipoprotein B mRNA-editing enzyme catalytic polypeptide-like (APOBEC) deaminases are the most common in EACSCC, suggesting its similarity to SCC from other primary sites. Analysis of arm-level copy number alterations detected notable amplification of chromosomes 3q, 5p and 8q as well as deletion of 3p across multiple samples. Focal chromosomal aberrations included amplifications of 5p15.33 (ZDHHC11B) and 7p14.1 (TARP) as well as deletion of 9p21.3 (CDKN2A/B). The protein expression levels of ZDHHC11B and TARP in EACSCC tissues were validated by immunohistochemistry. Moreover, WES of the primary and relapsed tumors from a case of synchronous bilateral EACSCC showed the intrapatient genetic heterogeneity of EACSCC. In summary, this study provides the first evidence for genetic alterations of EACSCC. Our findings suggest that EACSCC mostly resembles other SCC.

Surgical treatment of external auditory canal cholesteatoma in congenital malformation of the ear: A case series.

Project description:BackgroundExternal auditory canal (EAC) cholesteatoma is a lesion lined with stratified squamous epithelium containing proliferative keratin with bony erosion in EAC which can spread to the tympanic cavity, mastoid, and surrounding organ. External cholesteatoma can occur in patients with congenital abnormalities such as congenital aural atresia (CAA).MethodThis case series was reported using the 2020 PROCESS Guideline. The design of this study used a retrospective study during the 2015-2020 period.Result3 participants aged 10.67 ± 2.31 years with CAA had other complaints of ear infections. All participants experienced sensorineural hearing loss with an average threshold of 59.33 ± 36.68 dB and suspicious cholesteatoma from a CT scan. Canal wall down, meatoplasty, and/or canaloplasty were performed based on the findings.ConclusionSurgical procedure in CAA with cholesteatoma aimed on preventing further complications and recurrence.

Targeted molecular characterization of external auditory canal squamous cell carcinomas.

Project description:HypothesisSquamous cell carcinomas (SCC) of the external auditory canal (EAC) may harbor unique genomic alterations that may explain aggressive behavior and differentiate these tumors from cutaneous SCCs of other subsites.BackgroundEAC SCCs arise in a non-ultraviolet-exposed region of the head and neck, are often locally aggressive and may metastasize to lymph nodes or distant sites. The genomic alterations underlying cutaneous SCC of other sites are well-documented; however, mutational profiles of EAC SCC are less well characterized and may contribute to the unique anatomic site, high rates of recurrence and tumor spread. We performed targeted sequencing of a cohort of primary EAC SCCs to identify recurring and potentially targetable genomic alterations.MethodsGenomic DNA was extracted from formalin-fixed paraffin-embedded specimens of 7 EAC SCCs and subjected to targeted DNA sequencing using a 227-gene panel. Somatic alterations and gene copy number alterations were annotated using our validated, in-house bioinformatics pipelines.ResultsIn our EAC SCCs, we found recurrent alterations in TP53 and genes of receptor tyrosine kinase (eg, EGFR, FGFR) and PI3K pathways (eg, PIK3CA), similar to cutaneous SCCs of other head and neck sites. We also observed a high frequency of telomerase reverse transcriptase amplification and DNA methyltransferase 1 alterations, both of which are rarely observed in cutaneous SCCs of other sites.ConclusionThese data represent the first step toward precise molecular characterization of EAC SCCs that may lead to an enhanced understanding of tumor biology and modernized precision medicine approaches for unique tumors.Level of Evidence: NA.

Mastoid obliteration and external auditory canal reconstruction with silicone block in canal wall down mastoidectomy.

Project description:ObjectiveTo prevent cavity problems in canal wall down mastoidectomy, silicone block for mastoid obliteration was used.MethodsIn this retrospective cohort study, 39 patients (21 males and 18 females) underwent canal wall down mastoidectomy and mastoid obliteration using silicone block. We evaluated the postoperative outcome, the time until epithelialization of the cavity, graft success rate, and the hearing outcome.ResultsThe time until complete epithelialization of the mastoid cavity was 35.5 ± 5.4 days. We had a graft success rate of 100% during the follow-ups. The postoperative evaluation revealed 36 dry ears (92.3%) patients without any cavity problems. However, one ear developed granulation tissue, and two ears had partially exposed silicone block, which required revision mastoidectomy. Regarding hearing outcomes, a complication such as deaf ear was not reported.ConclusionSilicone block is safe and suitable for mastoid obliteration and external auditory canal reconstruction in canal wall down mastoidectomy.Level of evidence4.
