1/90. Papillary endothelial hyperplasia presenting as a chest wall neoplasm.Soft tissue hematomas generally resolve but may persist and develop into slow-growing, organized masses. These chronic expanding hematomas are characterized by a pseudocapsule and a predominantly necrotic central cavity, with foci of newly formed capillaries. These have been called chronic expanding hematomas or Masson's papillary endothelial hyperplasia. These lesions can mimic vascular neoplasms and must be considered in the evaluation of expanding soft tissue vascular malformations.- - - - - - - - - - ranking = 1keywords = papilla (Clic here for more details about this article) |
2/90. Adenomyomatous hyperplasia of the papilla of Vater: A sequela of chronic papillitis?A case of adenomyomatous hyperplasia of the papilla of Vater is described. The lesion presented as a small polypoid tumor projecting into the duodenal lumen, causing obstruction and dilatation of the common bile duct. Serial cross-section of the ampulla showed diffuse thickening of the muscular layer corresponding to Oddi's sphincter, with resulting narrowing of the lumen. Many ductal or glandular components were dispersed within the mucosa and the muscular layer and were admixed with lymphocytes, a few lymphoid aggregates, and fibrosis. Based both on the absence of cellular atypia and the presence of inflammation, fibrosis, and preservation of the normal architecture of the ampulla, we favor the interpretation that this hyperplastic lesion represents a sequela of chronic papillitis. The different diagnoses for this lesion are presented along with a review of the literature.- - - - - - - - - - ranking = 5keywords = papilla (Clic here for more details about this article) |
3/90. Gingival lesions diagnosed as pemphigus vulgaris in an adolescent. Case report.Desquamative gingivitis (DG) is a fairly common disorder in which the gingivae show chronic desquamation. Originally considered to be related to hormonal changes at menopause, since many of the patients are middle-aged women, DG is now recognized to be mainly a manifestation of a number of disorders ranging from vesiculobullous diseases to adverse reactions to a variety of chemicals or allergens. Desquamative gingivitis can be an important early clinical manifestation of serious systemic diseases such as pemphigus vulgaris. The authors present a case that illustrates the importance of a specific diagnosis in patients with desquamative gingival lesions previously treated for 6 months as classical gingivitis. Gingival biopsy showed histologic patterns typical of pemphigus vulgaris. The patient was treated with systemic and topical corticosteroids in association with miconazole. The patient is now under control with low-dose systemic corticosteroids. Proper recognition of lesions in the oral mucosa leads, in several situations, to an early diagnosis of a systemic disease.- - - - - - - - - - ranking = 0.30530920600794keywords = gingiva (Clic here for more details about this article) |
4/90. Spontaneous thrombosis of a pseudoaneurysm complicating pancreatitis.patients with a visceral aneurysm are at high risk for acute transpapillary, intra-, or retroperitoneal hemorrhage, necessitating either surgical or endovascular therapy. We report an instance of spontaneous thrombosis of a pseudoaneurysm complicating pancreatitis before endovascular treatment could be performed. causality and the literature of spontaneous thrombosis in pseudoaneurysms are discussed.- - - - - - - - - - ranking = 1keywords = papilla (Clic here for more details about this article) |
5/90. gingival hemorrhage, myelodysplastic syndromes, and acute myeloid leukemia. A case report.Myelodysplasia syndrome (MDS) presenting as spontaneous gingival hemorrhage is described. gingival hemorrhage is recognized as a symptom of MDS, a rare group of potentially fatal hematological disorders, but it has not previously been documented as a presenting sign. The diagnostic pitfalls are discussed with the case, and the need for careful interpretation of laboratory findings in conjunction with clinical signs is emphasized. Finally, the MDSs are defined, classified and discussed with respect to their relevance to the clinical periodontist, from a diagnostic, therapeutic, and management standpoint.- - - - - - - - - - ranking = 0.15265460300397keywords = gingiva (Clic here for more details about this article) |
6/90. Unusual peripheral odontogenic tumors in the differential diagnosis of gingival swellings.Differential diagnosis of gingival mass lesions includes several conditions and causes. Peripheral odontogenic tumors may mimic gingival swellings and, although rare, must be included in the differential diagnosis. The purpose of this article is to describe 3 different cases of peripheral odontogenic tumors and to discuss the differential diagnosis of gingival swelling. Histologic examination is mandatory when localized gingival swellings are surgically removed.- - - - - - - - - - ranking = 1.2212368240318keywords = gingiva (Clic here for more details about this article) |
7/90. Macroscopic and microscopic mucinosis in chronic sclerodermoid graft-versus-host disease.Secondary cutaneous mucinosis is a well-recognized feature of connective tissue diseases such as lupus erythematosus and dermatomyositis. We report the first three cases of dermal mucinosis in association with severe chronic cutaneous graft-versus-host disease of the sclerodermoid variety. One patient had clinical changes due to abundant mucin accumulation within the papillary dermis (mucinoma). In the other two patients histological examination revealed extensive deposits of mucin predominantly within the reticular dermis. The microscopic appearances were striking, with numerous vacuolated spaces interspersed between collagen bundles. We speculate that this appearance is the result of ground substance becoming trapped within grossly sclerodermoid connective tissue.- - - - - - - - - - ranking = 1keywords = papilla (Clic here for more details about this article) |
8/90. Hemosuccus pancreaticus complicating chronic pancreatitis: an obscure cause of upper gastrointestinal bleeding.BACKGROUND: Hemosuccus pancreaticus, a rare form of upper gastrointestinal bleeding, may complicate chronic pancreatitis and pose a significant diagnostic and therapeutic dilemma. AIM: To present our experience with this potentially life-threatening complication of chronic pancreatitis. methods: We reviewed our experience with management (both operative as well as angiographic embolization) of patients with hemosuccus pancreaticus complicating histologically documented chronic pancreatitis between 1976 and 1997. Diagnosis of hemosuccus pancreaticus was based on clinical presentation, preoperative endoscopic and radiographic imaging, operative findings, and pathologic evaluation. RESULTS: During the period, we managed eight patients with hemosuccus pancreaticus (1.5% of all patients with chronic pancreatitis treated surgically). Gastrointestinal bleeding presented as hematemesis in three and hematochezia in three, but all had recent melena and were anemic; three of these patients were hemodynamically unstable. abdominal pain was present in six. When performed, angiography (n=6) was diagnostic of a pseudoaneurysm; computed tomography (n=7) showed a pseudoaneurysm in two and a pseudocyst in five. endoscopy (n=8) revealed blood issuing from the ampullary papilla in two patients. Operative management (n=6) involved distal pancreatectomy, pancreatoduodenectomy, or total pancreatectomy in two patients each. Angiographic embolization was successful in one patient, but the other died from uncontrollable hemorrhage. CONCLUSIONS: Hemosuccus pancreaticus is rare, but should be considered in patients with chronic pancreatitis and gastrointestinal bleeding. In the absence of pancreatitis-related indications for surgery, angiographic embolization can be definitive treatment. If there are pancreatitis-related indications for operation, angiographic embolization may allow an elective operative procedure based on structural changes of the pancreas. If embolization fails, pancreatic resection is usually required, often on an emergent basis.- - - - - - - - - - ranking = 1keywords = papilla (Clic here for more details about this article) |
9/90. The spectrum of pediatric eosinophilic esophagitis beyond infancy: a clinical series of 30 children.OBJECTIVES: eosinophilic esophagitis, previously confused with esophageal inflammation due to gastroesophageal reflux, has recently begun to be distinguished from it. We undertook this analysis of our large series of children with the condition to clarify its spectrum: its presenting symptoms; its relation to allergy, respiratory disease, and reflux; its endoscopic and histological findings; and its diagnosis and therapy. methods: We analyzed the details of our clinical series of 30 children with eosinophilic esophagitis, defining it as > or =5 eosinophils per high power field in the distal esophageal epithelium. Retrospective chart review was supplemented by prospective, blinded, duplicate quantitative evaluation of histology specimens, and by telephone contact with some families to clarify subsequent course. Presentation and analysis of the series as a whole is preceded by a case illustrating a typical presentation with dysphagia and recurrent esophageal food impactions. RESULTS: Presenting symptoms encompass vomiting, pain, and dysphagia (some with impactions or strictures). Allergy, particularly food allergy, is an associated finding in most patients, and many have concomitant asthma or other chronic respiratory disease. A subtle granularity with furrows or rings is newly identified as the endoscopic herald of histological eosinophilic esophagitis. Histological characteristics include peripapillary or juxtaluminal eosinophil clustering in certain cases. association with eosinophilic gastroenteritis occurs, but is not common. Differentiation from gastroesophageal reflux disease is approached by analyzing eosinophil density and response to therapeutic trials. Therapy encompasses dietary elimination and anti-inflammatory pharmacotherapy. CONCLUSION: awareness of the spectrum of eosinophilic esophagitis should promote optimal diagnosis and treatment of this elusive entity, both in children and in adults.- - - - - - - - - - ranking = 1keywords = papilla (Clic here for more details about this article) |
10/90. Parasitic thyroid nodule in a patient with Hashimoto's chronic thyroiditis.A case of parasitic thyroid nodule is presented. The patient was a non symptomatic 53-year-old white woman, on irregular course of L-thyroxine to treat hypothyroidism due to Hashimoto's thyroiditis. Without a history of thyroid trauma or surgery, she presented a 1.6 x 0.7 x 0.5cm right pre-laryngeal lymph node-like mass which, on ultrasonography, appeared distinct from the gland. TSH, thyroid peroxidase antibody and thyroglobulin antibody serum levels were elevated and T4-free level was normal. Thyroid and total body 99mTc isonitrile scintiscan showed a topic thyroid without radionuclide uptake in the nodule. Fine-needle aspiration of the nodule showed epithelial cells with nuclear atypia and oncocytic changes plus intense lymphoid infiltration and germinative center formation, simulating lymph node metastasis of papillary thyroid carcinoma. Conventional biopsy revealed a parasitic thyroid nodule with Hashimoto's chronic thyroiditis. Parasitic thyroid nodule must always be remembered so that unnecessary surgical assessment and undesirable sequels may be avoided.- - - - - - - - - - ranking = 1keywords = papilla (Clic here for more details about this article) |
