1/59. Burkitt-like lymphoma presenting as a periodontal disease in AIDS patients: a report of two cases.Burkitt-like lymphoma of the oral cavity is relatively uncommon in patients with acquired immunodeficiency syndrome (AIDS). The lesion usually appears as a solitary ulcerated mass with rapid onset. Some may present initially as gingival inflammation which delays final diagnosis and treatment. This report describes the presentations of multifocal intraoral Burkitt-like lymphoma in two Thai heterosexual men with AIDS. The clinical features and the radiographic findings in both cases mimicked a periodontal disease, showing extensive widening of the periodontal ligament space and loss of lamina dura in all segments of the molar teeth. The patients eventually died 5 and 14 months after they were diagnosed with hiv infection.- - - - - - - - - - ranking = 1keywords = lymphoma (Clic here for more details about this article) |
2/59. Transmucosal fine-needle aspiration diagnosis of intraoral and intrapharyngeal lesions.OBJECTIVES: The effectiveness of fine-needle aspiration biopsy (FNAB) for the diagnosis of neck, thyroid, and salivary gland masses is well documented. Very few reports explore the potential of an intraoral FNAB approach for the diagnosis of submucosal lesions. We describe our technique and present case examples of pertinent differential diagnostic entities. We recommend an expanded role for FNAB of the oral cavity and oropharynx. STUDY DESIGN: Retrospective review. methods: A uniform technique was employed for transmucosal FNAB of 76 patients with intraoral masses. In applicable cases, cytology results were compared with traditional biopsy methods and permanent histopathologic specimens for accuracy. RESULTS: Our experience demonstrates the high sensitivity (93%) and specificity (86%) of intraoral FNAB when compared with biopsy by conventional means. FNAB provides distinct advantages for the cytologic diagnosis of submucosal lesions, which may be difficult to reach and adequately sample through conventional biopsy. FNAB of the tonsil and tonsillar fossa provides a safe and effective means of diagnosing both lymphoma and squamous cell cancer. Transmucosal FNAB via the mouth led to rapid diagnosis of a number of benign and malignant lesions. Applying this uniform FNAB technique, we had no significant complications. CONCLUSION: We recommend transmucosal FNAB as an effective means for highly accurate diagnosis of submucosal lesions of the oral cavity and oropharynx. CLINICAL RELEVANCE: Traditional biopsy techniques in the oral cavity may require anesthesia and may have diagnostic difficulties, particularly for submucosal lesions. Transmucosal FNAB overcomes these shortcomings by providing a minimally invasive means to rapid diagnosis of intraoral lesions.- - - - - - - - - - ranking = 0.16666666666667keywords = lymphoma (Clic here for more details about this article) |
3/59. Metastasising malignant lymphoma mimicking necrotising and hyperplastic gingivostomatitis.This paper presents the case of a 65 year-old woman suffering from recurrent oral aphthoid ulcers which rapidly evolved towards hyperplastic and ulcerated lesions over the entire floor of the mouth. The initial lesions were interpreted as non-specific aphthoid ulcers. Later, a tentative diagnosis of necrotising stomatitis with secondary reactive proliferating epithelial hyperplasia was made. The clinical symptoms and the immuno-phenotyping of lymphocytes circulating in the peripheral blood suggested the diagnosis of CD30-positive large cell anaplastic lymphoma. The biopsy showed only a pseudoepitheliomatous hyperplasia, reactive infiltrates and no lymphoma cells. The disease ran a fulminant course leading to death within 4 weeks due to acute gastro-intestinal bleeding. autopsy revealed infiltrates of CD30 large cell anaplastic lymphoma in a submandibular lymph node, in a thrombus stenosing the right subclavian vein, in the spleen, the anterior and posterior gastric wall as well as in the depth of the tumour on the floor of the mouth. The clinical and histopathological spectrum of CD30 large cell anaplastic lymphoma is considerably variable. The particular feature of pseudoepitheliomatous hyperplasia has been reported especially in CD30 anaplastic large cell lymphomas. An early correct diagnosis is rendered difficult in insufficient biopsy size, becauses this type of lymphoma often simulates other inflammatory or neoplastic skin diseases. Thus, with a necrotising and hyperplastic gingivostomatitis, the diagnosis of a CD30 anaplastic large cell lymphoma should be considered.- - - - - - - - - - ranking = 1.8333333333333keywords = lymphoma (Clic here for more details about this article) |
4/59. Intraoral papillary cystadenoma lymphomatosum.The literature related to intraoral papillary cystadenoma lymphomatosum is critically reviewed and the reported cases analyzed to determine the average age, sex, and race of patients, and the site distribution of this curious lesion. Two new cases are reported. The histogenesis and differential diagnosis from cystadenocarcinoma are briefly discussed.- - - - - - - - - - ranking = 0.83333333333333keywords = lymphoma (Clic here for more details about this article) |
5/59. Spontaneously relapsing clonal, mucosal cytotoxic T-cell lymphoproliferative disorder: case report and review of the literature.Primary T-cell lymphoma of the gastrointestinal tract is a rare and usually aggressive disorder that may be associated with celiac disease. The authors describe a unique case of a clonal proliferation of CD8 T cells involving the oral mucosa, ileum, and colon of a 35-year-old man that has regressed spontaneously and recurred numerous times over a 9-year period without treatment. The patient's symptoms were limited to occasional rectal bleeding and recurring painful oral ulcers. Within the intestine, these collections of small T cells induced minimal architectural distortions and did not show extensive epitheliotrophism. polymerase chain reaction and sequencing analyses revealed that the identical T-cell clone has been present for more than 9 years and in different mucosal locations in this patient. This may represent a unique T-cell lymphoproliferative process akin to a mucosal counterpart of lymphomatoid papulosis of the skin.- - - - - - - - - - ranking = 0.33333333333333keywords = lymphoma (Clic here for more details about this article) |
6/59. Spontaneous regression of an anaplastic large cell lymphoma in the oral cavity: first reported case and review of the literature.Lymphomas account for 2-5% of all oral malignancies and are the third most common in this site. This case report appears to be the first in the world literature describing spontaneous regression in the oral cavity of a subset of non-Hodgkins lymphomas known as Ki-1 anaplastic large cell lymphomas (ALCL). Ki-1 ALCL account for 2-7% of all non-Hodgkins lymphomas and the clinical presentation is variable; they may arise de novo or in the setting of a separate primary lymphoma and commonly present in the extra-nodal location. Disease severity is also variable with waxing and waning lesions at one extreme which may spontaneously regress to bone marrow involvement in around 12% of cases. This case is especially interesting since the patient is a farmer, given the recent evidence that there may be a link between non-Hodgkins lymphoma and this occupation.- - - - - - - - - - ranking = 1.5keywords = lymphoma (Clic here for more details about this article) |
7/59. Oral involvement in mycosis fungoides: report of two cases and a literature review.Oral involvement is uncommon in cutaneous T-cell lymphomas and usually associated with poor prognosis. The clinicopathological and immunohistochemical findings of 2 new cases are described along with a literature review. The first patient had a 10-year history of mycosis fungoides when she developed lesions in the oral tissues. She died 6 months later despite treatment. The immunophenotype was CD3 , CD4 , CD8-, CD30-. The second patient had a mycosis fungoides for 5 years when she developed lesions in the uvula and oropharynx. She was treated with polychemotherapy and she is alive 5 years after oral involvement. The immunophenotype was CD3 , CD4-, CD8 , CD30-. There are conflicting reports about the prognosis in the CD8 phenotype. The present cases and the literature review seem to indicate that in oral involvement the CD8- phenotype is not associated with a worse prognosis than the CD4 subtype. However, it is necessary to study new cases to confirm this statement.- - - - - - - - - - ranking = 0.16666666666667keywords = lymphoma (Clic here for more details about this article) |
8/59. Oral mucosal non-Hodgkin's lymphoma--a dangerous mimic.Reports of T-cell lymphomas in the oral cavity are rare. Most have presented as a persisting ulcerated swelling. This paper reports two men, one of whom presented with a short history of increasing facial swelling and pain apparently related to a lower premolar tooth, and the other who had recurrent oral ulceration in several sites over a period of years. These types of cases are likely to present initially to general dental practitioners.- - - - - - - - - - ranking = 0.83333333333333keywords = lymphoma (Clic here for more details about this article) |
9/59. Multiple primary tumors. Four distinct head and neck tumors.The case history of a 70-year-old woman with the simultaneous occurrence of mucoepidermoid carcinoma of the parotid gland, thyroid carcinoma, squamous cell carcinoma of the oral cavity, and a Warthin tumor is described. The simultaneous occurrence of three histologically distinct malignant tumors is a rare event amounting to approximately 1% of cases of multiple primary tumors. This case is unusual in that the tumors occurred in three separate organs and in association with a papillary cystadenoma lymphomatosum. While difficult to evaluate, prognosis and treatment should be approached with respect to each of the tumors as individual entities.- - - - - - - - - - ranking = 0.16666666666667keywords = lymphoma (Clic here for more details about this article) |
10/59. MALT lymphoma originating in breast and uvula.A case of marginal zone B cell lymphoma of MALT type arising in the uvula and breast is reported. The patient, a 30-year-old woman who delivered a child and lactated in 1997, was suffering from Sjogren syndrome (SS). She was diagnosed with MALT lymphoma after a biopsy of the right breast and uvula. To investigate the relationship of the delivery, lactation and MALT lymphoma, we examined the immunohistochemical analysis of hormone receptors. As a result, lymphoid cells of the breast were stained with anti-progesterone receptor antibodies in the cytoplasm. Consequently, the MALT lymphoma of the uvula appeared to be associated with SS. Moreover, hormones such as progesterone may have influenced the breast involvement of MALT lymphoma in our case.- - - - - - - - - - ranking = 1.5keywords = lymphoma (Clic here for more details about this article) |
