1/126. Extraparotid Warthin's tumor.Warthin's tumor (papillary cystadenoma lymphomatosum) is a well-known benign tumor of the parotid gland. Extraparotid tumors occasionally arise in the cervical region, where they may well be seen by the dermatologist. The following is a case report of an extraparotid Warthin's tumor encountered in a dermatology practice, with a review of the important clinical and histopathologic features of this tumor.- - - - - - - - - - ranking = 1keywords = gland, adenoma (Clic here for more details about this article) |
2/126. Synchronous unilateral parotid neoplasms of different histological types.The occurrence of multiple tumours in the salivary glands is an unusual phenomenon and the simultaneous development of tumours different types is extremely rare. Two cases are presented with synchronous tumours of the parotid gland of different histological types. The first was a Warthin tumour in combination with a metastatic lung carcinoma and the second was a pleomorphic adenoma in combination with non-Hodgkin's malignant lymphoma.- - - - - - - - - - ranking = 1.9616138829824keywords = gland, adenoma (Clic here for more details about this article) |
3/126. Squamous cell carcinoma arising in a Warthin's tumor.Warthin's tumor is a well-defined salivary gland neoplasm consisting of epithelial and lymphoid components. However, malignant transformation is extremely rare. Such a patient who developed squamous cell carcinoma within a Warthin's tumor of the parotid gland is described and possible pathogenesis is discussed.- - - - - - - - - - ranking = 1.9232277659647keywords = gland (Clic here for more details about this article) |
4/126. A review of heterotopia and associated salivary gland neoplasms of the head and neck.Salivary tissue neoplasms may involve normal, accessory and heterotopic salivary gland tissue. A case of Warthin's tumour originating from heterotopic salivary gland tissue of the upper neck is reported. The radioactive uptake of 131I, evidenced in the neck mass in its pre-diagnostic assessment, suggested a diagnosis of cervical node involvement from a primary malignant thyroid neoplasm. A critical review of the literature on heterotopic salivary gland tissue neoplasms of the head and neck is also presented.- - - - - - - - - - ranking = 6.7312971808765keywords = gland (Clic here for more details about this article) |
5/126. Synchronous ipsilateral sebaceous lymphadenoma and acinic cell adenocarcinoma of the parotid gland.The synchronous or metachronous occurrence of 2 tumors of the salivary glands in a patient is rare. These tumors are usually benign and of the same histologic type. Here we report a 78-year-old woman who developed a sebaceous lymphadenoma and an acinic cell adenocarcinoma simultaneously in the left parotid gland. To our knowledge, this combination of neoplasms has not been reported before.- - - - - - - - - - ranking = 5.9616138829824keywords = gland, adenoma (Clic here for more details about this article) |
6/126. Warthin's tumor of the parotid salivary gland. A case report.Neoplasms of the salivary glands are not uncommon. The dentist is in the unique position to make an early diagnosis and refer the patient for definitive treatment. This article will review the clinical appearance, pathology, treatment and potential complications of Warthin's tumor, a benign salivary gland tumor. It describes a case presented at the Salivary Gland Center.

8/126. Warthin's tumor. Report of a case and survey of 205 salivary neoplasms.A case of Warthin's tumor with an unusual sialographic appearance is reported. The extensive pooling of the contrast media within the tumor was probably the result of communication of the cystic spaces of the tumor with the ductal system of the parotid gland. This case stimulated a re-examination of the incidence of this tumor, with a study of 205 major salivary gland tumors from pathology reports in the files of Hartford Hospital which is affiliated with the University of connecticut health Center in Farmington, connecticut.- - - - - - - - - - ranking = 1.9232277659647keywords = gland (Clic here for more details about this article) |
9/126. adenolymphoma (Warthin's tumor) with multiple sarcoid-like granulomas.Five cases of adenolymphoma (Warthin's tumor) (AL) with numerous sarcoid-like granulomas within the lymphoid stroma are described. All patients were males, aged from 44 to 71 years (mean 57.3 years); all tumors were localized in the parotid gland. Fine needle aspiration cytology was performed in two cases 7.5 and 2 weeks before operation, respectively. Microscopic examination demonstrated the typical structure of AL. In addition, dispersed throughout the lymphoid stroma there were numerous granulomas formed by both epithelioid and multinucleated giant cells of Langhans type, strongly resembling sarcoidosis. The pathogenesis of the granulomatous change remains speculative. It could be caused by a toxic effect of the cysts' contents but probably not by its direct action; the spread of the fluid via sinuses into the lymphatic tissue seems to be more probable. We presume that the previous FNA may have some triggering effect. Granulomatous transformation of the lymphoid stroma resembling sarcoidosis is rare, but should be included in the spectrum of secondary changes in AL. It is not limited to metaplastic AL; it can be seen in an otherwise typical AL without any additional histologic changes. knowledge of a previous FNA and awareness of the possibility of this peculiar histologic change are necessary to avoid incorrect diagnosis.- - - - - - - - - - ranking = 0.96161388298236keywords = gland (Clic here for more details about this article) |
10/126. Follicle center lymphoma and Warthin tumor involving the same anatomic site. Report of two cases and review of the literature.We report 2 cases of follicle center non-Hodgkin lymphoma (NHL) and Warthin tumor involving the same site. Case 1 is a 68-year-old woman with Warthin tumor and grade 1 follicular NHL involving a periparotid lymph node. She had localized NHL and was treated with radiation therapy; dissemination developed 54 months later. Case 2 is a 55-year-old man with a 17-year history of a parotid mass with gradual enlargement during the last 5 years. Surgical excision revealed Warthin tumor and grade 1 follicular NHL involving the right parotid gland and surrounding lymph nodes. Immunohistochemical studies supported the diagnosis of NHL in both cases; the neoplasms were positive for CD20 and BCL-2 and negative for CD3. polymerase chain reaction analysis done on paraffinembedded tissue of case 1 revealed monoclonal immunoglobulin heavy chain gene rearrangement and bcl-2/JH fusion dna sequences diagnostic of the t(14;18)(q32;q21). The small size of the Warthin tumor in case 1, clearly arising in lymph node, supports the hypothesis that Warthin tumor arises from heterotopic salivary gland ducts within lymph nodes. The localized NHL in both patients suggests that the NHL initially arose in the lymph node involved by Warthin tumor, and, thus, the Warthin tumor may have provided a source of long-term antigenic stimulation from which a monoclonal B-cell population subsequently arose.- - - - - - - - - - ranking = 1.9232277659647keywords = gland (Clic here for more details about this article) |
