Rare Location of a Dermoid Cyst in the Parotid Gland: A Case Report (original) (raw)

Dermoid cyst of parotid gland; Report of a rare entity with literature review

The Professional Medical Journal

Dermoid cysts are developmental cysts in young adults that are very uncommon in head and neck area. In oral and maxillofacial area the cysts are mainly present in the submental triangle and in floor of mouth. In the neck dermoid cysts usually present as midline neck mass. Parotid gland is extremely rare site at which the dermoid cysts develop. There are only 19 reported cases till date. Superficial parotidectomy is the suggested surgical treatment, however sometimes enucleation is all that is needed. We present a rare case of this entity which was pre-operatively diagnosed as pleomorphic adenoma on Fine Needle Aspiration Cytology.

DERMOID CYST OF THE PAROTID GLAND Head and Neck Surgery

2019

PAROTİS BEZİNDE DERMOİD KİST Baş ve boyunda yerleşmiş dermoid kistler benign lezyonlardır ve histolojik olarak ektoderm ve mezoderm orjinli dokulardan oluşurlar. Parotis bezinde çok nadir görülürler ve parotis kitlelerinin ayırıcı tanısında düşünülmeleri gerekir. Literatürde yayınlanmış çok az vaka vardır. Tedavi cerrahi olup, yüzeysel parotidektomi önerilse de, kitlenin enükleasyonu tedavi için yeterlidir. Bu yazıda, sağ parotis bezi yüzeyel lobda yerleşmiş kistik kitle nedeniyle ameliyat edilen dermoid kist olgusu sunuldu, tanı ve tedavisi tartışıldı. Abstract

A Rare Mass of the Neck: Dermoid Cyst

2015

Dermoid/epidermoid cysts are rarely seen in the neck region. They generally present as a slowly growing mass located in the midline. Radiologic methods can be helpful in diagosis. Magnetic resonans imaging (MRI) has special importance both for diagnosis and treatment with its multiplanar imaging capacity and ability to define the relationship between the lesion and adjacent structures. We present a rare case of dermoid cyst in a 20-year-old man. He complained of a painless mass located in the suprasternal region. Ultrasonography (US), computerized tomography (CT) and MRI findings of the lesion suggest dermoid/epidermoid cyst. The mass was resected and histological examination confirmed the diagnosis of dermoid cyst. Even if dermoid cysts are rare neck masses, they sould be kept in mind in differential diagnosis of midline cysts.

An unusual dermoid cyst presenting as midline swelling of neck in an adult patient

International Journal of Otorhinolaryngology and Head and Neck Surgery

Dermoid cysts are true hamartomas focal malformations that can resemble neoplasms grossly and even microscopically but they arise from an abnormal formation of tissue elements. Here we are presenting a 44 years old woman presented with a midline mass in the neck present for many years. Fine-needle aspiration biopsy showed single and anucleate squamous along with few mature squamous cells against the background of debris. No atypical cells were seen. Ultrasonical examination revealed well-defined thick-walled area in the midline measuring 37×27 mm. Histologic examination of the cystic content identified epidermis, sebaceous glands, and hair follicles along with copious sebaceous material. These findings are consistent with a dermoid cyst. So, our case report demonstrates that dermoid cysts can present as neck mass and must be kept in the differential diagnosis. Even though characteristic radiological and histopathological features make the diagnosis simple yet, it may be difficult to...

Dermoid cyst of the oral cavity: A case report

Medical review, 2018

Introduction. Dermoid cysts are benign developmental skin growths that can occur in any part of the body. Dermoid cysts of the head and neck account for 7% of all cysts, and are most frequently located near the lateral aspect of the eyebrow. They are rarely found in the oral cavity, accounting for 0.01% of all oral cavity cysts. Case Report. A 15-years-old patient was referred to our Clinic due to a growth in the mouth. Clinical examination and magnetic resonance imaging showed a clearly demarcated, oval, cystic growth in the midline sublingual region. Intraoral incision, typical for frenectomy, with cyst excision was performed. Histopathological findings suggested a dermoid cyst. Conclusion. Dermoid cysts of the oral cavity are very rare; they grow slowly and when they reach certain dimensions, they interfere with chewing, swallowing, and lead to progressive breathing difficulty. Dermoid cysts should be included in the differential diagnosis of sublingual mass. Magnetic resonance i...

Epidermoid and dermoid cysts of the head and neck region

Plastic and Aesthetic Research, 2016

Epidermoid cysts, dermoid cysts and teratoid cysts are cystic malformations lined with squamous epithelium. They present as soft nodular lesions with a sessile base. Their prevalence is 7% in head and neck patients and 1.6% within the oral cavity. The authors present a case series of 21 patients with dermoid and epidermoid cysts who underwent surgical removal. One year of follow-up was carried out without evidence of recurrence. The removal of these cysts is of great concern as it can cause serious social stigma, aesthetic and functional impairment, dysphagia and dysphonia. ABSTRACT Article history:

Mucus Retention Cyst of Parotid Gland: A Rare Case Report

Scholars Journal of Medical Case Reports, 2020

Swellings of the major salivary gland commonly lead to the differential diagnosis which includes benign and malignant tumors that are frequently associated with cystic degeneration or entirely cystic in nature. Mucus retention cysts are true cysts that rarely involve the major salivary glands. 6% to 9% of the major salivary gland swellings present as a cystic lesion and only 2-5 % of them are non-neoplastic in nature. A 21 year-old female patient presented with swelling in right parotid region for last one and half years. CECT of the parotid region show a well-defined oval fluid density lesion measuring 2.4cmx1.9cmx3.4cm in the superficial lobe of the right parotid gland with extension into the deep lobe of the parotid gland. On FNAC, 7ml creamish fluid was aspirated which on microcopy showed foamy histiocytes in a mucoid background. A diagnosis of benign cystic lesion was made cytologically. The patient underwent right subtotal parotidectomy. Gross examination revealed a globular soft tissue piece with attached fatty tissue piece measuring 5x4x3cm. On cut section a cystic cavity identified measuring 3.5x2.7x2.0cm. Cyst cavity was filled with thick mucoid material. Microscopic examination revealed a cyst lined by cuboidal and partially by pseudostratified columnar epithelium. Interspersed mucus cells also present in lining epithelium. Lumen of cyst showed proteinaceous material. Compressed salivary gland parenchyma also seen at the periphery. No cellular atypia was seen. A diagnosis of Mucus retention cyst of right parotid gland was rendered histopathologically.

Surgical Presentation and Outcome of Parotid Gland Tumours

Journal of the College of Physicians and Surgeons Pakistan Jcpsp, 2013

OBJECTIVE: To assess the clinical presentation and outcome of surgical management of various parotid gland disorders requiring parotidectomy.STUDY DESIGN: Case series.PLACE AND DURATION OF STUDY: Department of General Surgery, Pakistan Institute of Medical Sciences (PIMS), Islamabad, from January 2003 to December 2010.METHODOLOGY: Patients presenting in surgical OPD with parotid gland disorders requiring parotidectomy were included. Data were obtained through the Hospital Management Information System (HMIS) and patient charts. The sociodemographic profile of the patient, presenting features among patients, benign versus malignant nature of the disease, FNAC reports, type of surgical procedure instituted, complications encountered and histology reports of the surgical specimens were all recorded on a proforma. The data were subjected to statistical analysis with SPSS version 15.RESULTS: Out of 126 patients, 62 (49%) were males and 64 (51%) females with mean age of 41 ± 12.6 years. All had presented with a lump usually painless. One hundred and fourteen (90.47%) patients had benign pathology while 9.52% (n = 12) had malignanciy. Superficial parotidectomy was carried out in 79.36% (n = 100) patients, total parotidectomy in 19% (n = 24) and extended total parotidectomy was performed in 2 cases (with mucoepidermoid carcinoma). The most common post-operative complication was greater auricular nerve paresis (n = 19; 15%) followed by facial nerve transient paresis (n = 10; 8%). There was no in-hospital mortality.CONCLUSION: Parotid gland lumps commonly affect relatively young individuals of either gender. Most of the patients have benign pathology. Superficial parotidectomy is the most commonly offered surgical procedure. Parotid surgeries are safely performed in general surgery units with low morbidity and no mortality.
