Résumé :

We report a case of a parapharyngeal cystic metastatic lymph node arising from papillary thyroid carcinoma (PTC). Parapharyngeal metastases arising from PTC are rare and correct diagnosis of the parapharyngeal mass before surgery is difficult. In this case, the diagnosis of a parapharyngeal mass was made pre-operatively by thyroglobulin measurement in peroral fine-needle aspiration with negative cytology.

Résumé :

The parapharyngeal space is a complex anatomic area which can give rise to a variety of both primary and metastatic neoplasms. Squamous cell carcinoma can also present as a parapharyngeal space mass, either by direct extension or by metastases. Occult thyroid carcinoma presenting as a parapharyngeal space mass is a rare clinical occurrence which has been only sporadically reported in the medical literature. We present a case of occult papillary thyroid cancer with parapharyngeal space metastasis in the form of an isolated tumor, as well as a review of the literature on similiar presentations.

Résumé :

Intraductal carcinomas are rare, malignant tumors that arise from the salivary glands. They commonly grow from the parotid gland and no cases growing from the parapharyngeal space have been reported to date. We report a 76-year-old man who was inadvertently found to have a parapharyngeal lesion by CT scans and MR imaging. The tumor was resected through an upper neck approach and diagnosed histopathologically as intraductal carcinoma. As far as we are aware, this is the first case of intraductal carcinoma arising from the parapharyngeal space. Here, we describe the management of this disease to

Résumé :

Parapharyngeal space tumour is rare in paediatrics. It can either be a primary tumour arising from parapharyngeal space structures, an extension from the surrounding structures or a metastatic tumour. In adults, salivary gland tumours and paragangliomas are common, while neurogenic tumours predominate in paediatrics. The delicate anatomy in the parapharyngeal space makes the diagnostic procedures more complex, especially in paediatrics. Although tissue biopsy can be obtained under sedation or local anaesthesia, it is histologically difficult to differentiate lipoma from liposarcoma. We present

Branchial anomalies can present in the parapharyngeal space, creating unique challenges in management. Historically, this approach warranted an open approach, including transcervical, transparotid with total parotidectomy and retromandibular dissection, or transmandibular dissection with mandibulotomy. However, the advent of minimally invasive transoral techniques and laser resection have allowed for successful resection of masses in this anatomical region without an external approach.

On physical examination, the tonsils were exudative and hypertrophic and the pharynx was hyperaemic. A fluctuant, 4 × 4 cm mass was seen on endoscopic examination, originating from the left parapharyngeal area and pr

AbstractBackground:Parapharyngeal space tumours are uncommon and represent 0.5–1 per cent of all head and neck neoplasms; 20–30 per cent of these are malignant. Malignant peripheral nerve sheath tumours are rare and mostly encountered in patients with neurofibromatosis type 1. Only four cases of parapharyngeal space tumours have been reported in the English language in patients without neurofibromatosis type 1.Case report:We report the case of a 64-year-old man with no stigmata of neurofibromatosis type 1, in whom a mass in the left pre-styloid region of the parapharyngeal space was an inciden

Background: Synovial sarcoma is a rare soft tissue sarcoma in the head and neck region and parapharyngeal space. There is no previous cytologic report of synovial sarcoma of parapharynx. The cytologic and immunocytochemical findings of a parapharyngeal biphasic synovial sarcoma together with diagnostic pitfalls are described. Case report: A 21-year-old girl presented with a 6-month history of progressive right arm pain, neck mass and upper aerodigestive tract obstruction. On physical examination there was a large painless mass arising from the right-sided parapharyngeal space causing airway ob

Résumé :

Abstract The incidence of parapharyngeal space (PPS) tumors is less, approximatively accounting for 0.5%–1.5% of all head and neck neoplasms. Of these PPS tumors, most of them are benign (70%–80%) and 20%–30% are malignant in nature. We present the case of a PPS tumor with atypical presentation on examination and an unusual progression in tumor growth. A 37-year-old female presented with chief complaints of snoring and change in voice, which was muffled in nature, since 6 months and complained of difficulty in breathing since 1 month, especially in performing activities. On examination, the or

ABSTRACT Extraskeletal osteochondroma in parapharyngeal space is very rare. It is important to note that such a diagnosis be considered when a discrete, ossified mass is localized in soft tissues, even at atypical sites. Its diagnosis is based on radiological and histopathological examination. We should be clinically aware of this benign entity as no malignant transformation or metastasis has been reported. Excision with adequate cuff of tissue is treatment of choice. We did not encounter any case report of osteochondroma in the parapharyngeal space in literature, with our best possible effort

Résumé :

Abstract Solitary fibrous tumors (SFT) rarely occur in the neck region and can be easily mistaken for more common tumors if the index of suspicion is not high. They are characterized by remarkable histologic variability. However, immunopositivity for CD34 and Bcl2 with immunonegativity for other markers aid in establishing the diagnosis. Distinction from the other common benign entities is essential, as SFT are tumors of low grade aggressiveness and unpredictable biologic behavior. Complete resection is the key feature determining outcome.

<p class="abstract">Schwannomas are uncommon neurogenic tumors that are typically benign, slow growing, and asymptomatic. Upto 45% of schwannomas arise from the head and neck region, the sites of origin are: face, scalp, intracranial cavity, orbit, nasal and oral cavities, parapharyngeal space, middle ear, mastoid, larynx, and medial and lateral regions of the neck. The age distribution is 30 to 70 years and male:female 3:1. Symptoms and signs are neck swelling (54%), pain (11%), cranial nerve palsy (10%), oropharyngeal swelling (8%), dysphagia (6%) and trismus, otalgia (11%). This case

Among all head and neck tumours, approximately 0.5% to 0.8% localize in the parapharyngeal space, with Non-Hodgkin’s lymphomas in this region being exceptionally rare. They are documented in the literature either as isolated cases or in small case series. Here, we present a case involving a middle aged man who exhibited 4 month history of dysphagia and hoarse voice. Upon examination, showed a bulged left side of the soft palate and medialization of the pharyngeal wall.

Rhabdomyoma is a benign tumor that comes from skeletal tissue, it is classified as cardiac and extracardiac according to the location. Extracardiac rhabdomyomas most frequently originate in the head and neck at the larynx and pharynx, being the parapharyngeal space an exceptional location. We present the clinical case of an 86-year-old man asymptomatic patient with a laterocervical mass with years of evolution, that has increased its size progressively, with dysphagia and dyspnea on exertion in the last years.
