BACKGROUND: Carcinoma showing thymus-like elements (CASTLE) is a rare tumor that normally affects the thyroid gland and was thought to arise from either the remnants of the branchial pouch or the ectopic cervical thymic tissue. These tumors show strong immunopositivity for CD5, P63, and CD117. Most CASTLE of the thyroid gland is treated with surgery with or without adjuvant radiotherapy or chemotherapy. METHOD: A 55-year-old woman presented with a slow-growing right parotid mass...

OBJECTIVE: The aims of this study are to evaluate the utility of sonoelastography for parotid gland masses and to determine which cutoff strain ratio (SR) would be best for the differentiation between benign and malignant lesions. METHODS: From August 2015 to December 2016, 39 parotid gland masses were examined prospectively by ultrasonography and strain sonoelastography. Elastographic scores were determined by a 4-point scoring method. Interventional procedures were performed on all patients after sonographic examinations...

Background: Kimura disease (KD) is a systemic soft-tissue disease that leads to formation of painless masses in lymph nodes, with the highest predilection for the head and neck and especially the parotid gland. KD lesions are characterized by marked eosinophil infiltration, production of IgE and increased expression of T-helper type 2 (Th2) cytokines (interleukin [IL]-4, IL-5, etc.). Skewing to a Th2 inflammation is also demonstrated in the peripheral blood, with elevated eosinophils and high IgE levels...

Myoepitheliomas are extremely rare salivary gland tumors. Myoepithelioma of salivary glands comprised only 1% of all salivary tumors, most commonly occurring in the parotid gland followed by the minor salivary glands in the oral cavity. Involvement of the soft palate is a rare occurrence. This tumor is usually benign, and its treatment is total lesion excision. Here, the author reports a case of myoepithelioma of the soft palate in a 42-year-old Turkish man. The mass was removed by local excision under general anesthesia...

Hydatid disease of the parotid gland is a very rare entity and may be easily overlooked in the diagnosis of parotid masses. Although Turkey remains an endemic area for echinococcosis, involvement of the parotid gland is extremely rare. A 26-year-old man presented with primary parotid gland mass without any other organ involvement. During the first surgery, the cyst was perforated accidentally and in a short time recurrence was occurred. Maximum attention was given for the second surgery for total removal without damaging the cyst with medical treatment...

Mantle cell lymphoma (MCL) is a malignant B-cell neoplasm, which comprises monomorphic and small- to medium-sized mantle zone-derived lymphoid cells. It is characterized by chromosomal translocation t(11;14)(q13;q32) and CCND1 truncation, resulting in cell cycle deregulation. It is an aggressive type of non-Hodgkin lymphoma with a propensity to present with extranodal involvement. This study shows the case of an 80-year-old Caucasian male who complained of a 2-month progressive swelling on the right side of his face...

Salivary gland tumours constitute about less than 4 % of all head and neck tumours. Pleomorphic adenoma, also called benign mixed tumour, is the most common tumour of the salivary glands. About 80-90 % of these tumours occur in the major salivary glands mainly parotid gland and 10 % of them occur in the minor salivary glands. The most common site for pleomorphic adenoma of the minor salivary glands is the palate, followed by the lips and the cheeks. Other rare sites include the floor of the mouth, tongue, tonsil, pharynx, retromolar area and the nasal cavity...

Adamantinoma-like Ewing sarcoma (AES) is a rare variant of Ewing sarcoma family of tumors (EFTs), primarily affecting bone and soft tissue. AES has mixed features of Ewing sarcoma (ES)/primitive neuroectodermal tumor (PNET) and adamantinoma with a complex immunoprofile and EWSR1 gene rearrangements. Herein, we report a 72-year-old male who presented with left parotid mass, right neck mass and thyroid nodules. Fine needle aspiration of the left parotid mass displayed nests of monotonous epithelioid cells with basaloid features in a background of small round blue cells and lymphocytes...

A 16-year-old castrated male mongrel cat presented with swelling under the left pinna and a 3 -month history of voice change. Laryngeal endoscopy revealed circumferential oedema around the arytenoid cartilages and hypersecretion of saliva. Histopathological examination of the mass around the left ear canal was considered the primary lesion that originated from cutaneous apocrine adenocarcinoma or parotid gland adenocarcinoma, and it metastasized to the larynx, lung and medial retropharyngeal lymph nodes. This report provides new insights into feline laryngeal diseases which could result in laryngeal metastasis with slight mucosal irregularity alone and without obvious radiographic abnormalities...

Warthin tumor is the second most common salivary gland neoplasm. It occurs more commonly in males than in females. Malignant transformation in Warthin tumor is a rare but well-recognized phenomenon; however, the development or presentation of lymphoma in a Warthin tumor is rare. An 80-year-old man presented with painless mass of the right parotid gland of 2 years duration with recent ulceration of the overlying skin and right cervical lymphadenopathy underwent a surgical resection of parotid mass and biopsy of the periglandular lymph nodes...

RATIONALE: Among the nontuberculous mycobacteria, Mycobacterium abscessus is a common cause of skin, soft tissue, and bone infections. However, disseminated M. abscessus infection that mimics cancer metastasis with an underlying relatively immunocompetent condition has rarely been reported. PATIENT CONCERNS: A nonsmoking 73-year-old man with an underlying relatively immunocompetent condition reported a 2-month history of a mass in the region of his right parotid gland that had been steadily increasing in size...

Accessory parotid gland (APG) is seen in around 21%-56% of individuals. Tumors of accessory parotid are uncommon with an incidence rate of 1%-8% of all parotid tumors. Ductal carcinoma of APG is rare, so no reported incidence was seen in the literature. However, salivary gland ductal carcinoma is reported to be 1% of all salivary gland neoplasms. We report here a case of salivary duct carcinoma of APG. Clinical presentation, investigation, and management are discussed. A 69-year-old female presented with a history of the left cheek progressive swelling of 6 years' duration...

The purpose of this study was to determine the incidence of an anterior extension of the parotid gland, such as an accessory parotid gland (APG) or facial process (FP) and to evaluate its characteristics on computed tomography (CT) scans. We reviewed CT scans of 1,600 parotid glands from 800 patients. An APG on CT was defined as a soft-tissue mass of the same density as the main parotid gland, located at the anterior part of the main parotid gland, and completely separate from the main parotid gland. An FP was defined as a lobe of the parotid gland protruding anteriorly over the anterior edge of the ramus of the mandible on CT and showing continuity with the main gland...

Frey's syndrome and infra-auricular depressed deformities are the ones of the most common complications that can occur after total parotidectomy. We report 1 case of pleomorphic adenoma occurred in the deep lobe that obtained good results from using acellular dermal matrix (ADM) after total parotidectomy. A 24-year-old man visited the hospital with oval shape mass in right mandibular angle which of 4 cm in size was found in the deep lobe of right parotid gland from Magnetic resonance imaging scanning and a pleomorphic adenoma was suspected...
