1/97. Lymphoepithelial cyst with crystalloid formation. Cytologic features of two cases.BACKGROUND: The presence of amylase crystalloids (AC) in cystic lesions of the parotid gland is a rare occurrence and has been diagnosed to date as sialadenitis. We report the first two cases of parotid lymphoepithelial cyst (LC) containing this type of crystalloid. CASES: Case 1, a 56-year-old male, presented with a 3-cm parotid cyst. Fine needle aspiration (FNA) was performed on the mass. Smears showed numerous crystalloids identical to those described as crystallized amylase. Case 2, a 36-year-old female, had a 2-cm parotid mass. FNA smears exhibited the same features as did case 1. The two patients were treated with superficial parotidectomy, and an LC containing AC was diagnosed in both cases. CONCLUSION: When the above findings are present on FNA of parotid gland, the diagnosis of LC must be considered.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
2/97. Synchronous pleomorphic adenomas of the major salivary glands: a case report.The presentation of multiple distinct tumors in major salivary glands is rare. Although the most common tumor with bilateral synchronous or metachronous development is the Warthin tumor, pleomorphic adenomas have been diagnosed simultaneously as well. We report the case of a female patient who was diagnosed with pleomorphic adenomas in the right parotid and submandibular glands, concomitant with sialolithiasis affecting the submandibular gland. This patient had been exposed to head and neck radiotherapy in childhood, which may have played a role in the development of her tumors. A review of the relevant literature is included.- - - - - - - - - - ranking = 3.5081049610387keywords = gland, adenoma (Clic here for more details about this article) |
3/97. Chronic sclerosing sialadenitis of the submandibular gland associated with idiopathic retroperitoneal fibrosis.We report a case of a 57-year-old man who developed a fibrosclerosing lesion in the submandibular gland and idiopathic retroperitoneal fibrosis (IRF) involving the unilateral periureteral region within a year. Both lesions were resected surgically because of the suspicion of neoplasm. Pathologic examination revealed similar histologic and immunohistochemical features for both lesions, namely, fibrosclerosis with prominent hyalinizing collagen bundles and proliferation of myofibroblastic cells, and a non-neoplastic reactive nature. There was infiltration by lymphocytes with prominent lymph follicles, plasma cells and macrophages. The histologic and immunohistochemical findings suggest that the two lesions were of a similar pathogenesis, which was possibly mediated by macrophages. We think that the present case may be an unusual form of multifocal fibrosclerosis. Although sialolithiasis is thought to be a major pathogenic factor for chronic sclerosing sialadenitis of the submandibular gland, the present case suggests that certain cases might have an etiology similar to IRF.- - - - - - - - - - ranking = 3keywords = gland (Clic here for more details about this article) |
4/97. Sialolithiasis: the radiolucent ones.Radiolucent calculi are discussed. Three cases are presented, with a sialographic interpretation of each. Recent studies show that radiolucent calculi in general and parotid gland sialolithiasis in particular occur more frequently than was previously believed.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
5/97. Parotid duct carcinoma arising in bilateral chronic sialadenitis.It is well recognized that, in general, chronic inflammation can predispose to malignant change. There is however, to our knowledge, no previously reported association between chronic obstructive sialadenitis and salivary gland epithelial malignancy. We describe here the first reported example in the English literature of a salivary duct carcinoma arising in a parotid gland with a long history of chronic obstructive sialadenitis. It is possible that a causal relationship exists between the two conditions. If this were the case then non-surgically treated chronic obstructive sialadenitis patients may well warrant careful clinical follow-up.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
6/97. Oral swelling in sjogren's syndrome.A case is reported of a 69-year-old female with sjogren's syndrome who presented with a problem of interest to the oral surgeon. The clinical features and cryosurgical management of a rare cause of palatal swelling are described. The confusion that exists in the literature concerning the nomenclature of chronic inflammatory salivary gland lesions is discussed.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
7/97. Immunological similarities between primary sclerosing cholangitis and chronic sclerosing sialadenitis: report of the overlapping of these two autoimmune diseases.Primary sclerosing cholangitis (PSC) is characterized by destructive inflammation and fibrosis affecting the bile ducts. The etiology of PSC is still unknown, although lymphocytic infiltration in the portal areas suggests an immune-mediated destruction of the bile ducts. patients with one autoimmune disease often suffer from one or more other autoimmune diseases. It is well known that there is a close relationship between PSC and inflammatory bowel disease, particularly ulcerative colitis(UC). However, the pathological findings in UC and other overlap diseases do not resemble those of PSC. In the present study, we report a patient with chronic sclerosing sialadenitis (Kuttner's tumor) and PSC. It is compared the sclerosing changes in both salivary glands and bile ducts histologically. In addition, the expression pattern of mast cell tryptase, b-FGF, and HLA-DR were examined in both tissues immunohistochemically. Histological features of sclerosing change in both salivary and bile ducts were quite similar. Marked mast cell infiltration and b-FGF expression were seen in the sclerosing areas in both tissues. In active inflammatory areas of the salivary glands, HLA-DR expression was also seen. We hypothesized that similar immune reactions occur in both the salivary gland and bile ducts and are responsible for the fibrosis that follows.- - - - - - - - - - ranking = 1.5keywords = gland (Clic here for more details about this article) |

9/97. Chronic sclerosing sialadenitis of the submandibular and parotid glands: a report of a case and review of the literature.Chronic sclerosing sialadenitis (also known as Kuttner tumor) is a chronic inflammatory condition of the salivary glands, first described by Kuttner in 1896. Clinically, the disease cannot be distinguished from a true neoplasm. The submandibular gland is affected more commonly than any other salivary gland. This report is of a case of widespread swelling of the salivary glands in which histologic features of chronic sclerosing sialadenitis were seen in the submandibular and parotid glands. The etiology, pathogenesis, and differential diagnosis of this disease and the clinical outcome of this case are discussed and presented.- - - - - - - - - - ranking = 4.5keywords = gland (Clic here for more details about this article) |
