1/227. Tonsillar lymphoma and AIDS.

    A case of a patient presenting unilateral tonsillar enlargement, whereby non-Hodgkin lymphoma (NHL) and AIDS were diagnosed, is presented. The clinical and pathological aspects of this pathology, its pathogenicity and treatment are reviewed. ( info)

2/227. The blastic variant of mantle cell lymphoma arising in Waldeyer's tonsillar ring.

    We present three cases of blastic mantle cell lymphoma with an unusual initial manifestation in Waldeyer's ring with methods for differentiating it from other blastic neoplasms of the head and neck. All cases presented with a feeling of fullness in the area of the mass. Morphologically, the tumours were blastic with a high mitotic rate (three to nine per high power field). All were B-cell phenotype with coexpression of CD43. In all cases cyclin d1 and bcl-2 were positive and CD23 negative. Blastic mantle cell lymphoma occurring in Waldeyer's tonsillar ring may be mistaken for other high grade haematopoietic neoplasms. immunohistochemistry and awareness of this type of lymphoma are helpful in differentiating it from other neoplasms.

3/227. Gastric adenocarcinoma with tonsil and submaxillary gland metastases: case report.

    Local invasion, hematogenous and lymphatic metastases are the major modes of spreading gastric cancer. The most common sites of metastases in patients with gastric cancer are liver, peritoneum, omentum, lungs and mesentery. Of the two pathological types of gastric cancer, intestinal-type gastric cancer showed preferential metastasis to the liver, whereas the diffuse-type showed a preference for peritoneal involvement and lymph node metastasis. However, metastases of gastric cancer to the head and neck regions are not common. The hematogenous route appears to account for a great majority of metastases to the head and neck regions. Malignant neoplasm metastases to major salivary glands or tonsils are not common. Several patients with cancers from the infraclavicular area have been reported with parotid gland or tonsil metastases. However, metastasis of gastric adenocarcinoma to the tonsils or submandibular glands is rare. We present a patient with recurrent gastric adenocarcinoma with both tonsil and submandibular gland metastases which is even rarer. ( info)

4/227. Late onset of tonsillar metastasis from breast cancer.

    A 71-year-old woman non-smoker referred for repeated haemoptysis showed a tumoral lesion of the left tonsil. Pathological analysis of the biopsy showed characteristics compatible with a breast carcinoma metastasis, in which oestrogen and progesterone receptors were present. The patient had undergone mastectomy and had received adjuvant radiotherapy 24 years previously for a breast cancer with no complaints or signs of recurrence since. Investigations showed disseminated bone metastases but no other soft-tissue deposits. Anti-oestrogen therapy was applied. Only seven similar cases of tonsillar metastasis from breast cancer have been reported. ( info)

5/227. Bilateral synchronous tonsillar carcinoma.

    Synchronous cancers occur in four per cent of patients with head and neck malignancies but no bilateral synchronous tonsillar carcinomas have been described in the English literature. We describe the first such case and discuss the prognostic aspect of this carcinoma. In the presence of contralateral neck nodes in patients with head and neck malignancies, a careful search should be made for a second head and neck primary. ( info)

6/227. 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. ( info)

7/227. Multilobated large B-cell lymphoma diagnosed cytologically. A case report.

    BACKGROUND: Fine needle aspiration (FNA) biopsy can be used to reliably classify most conditions involving lymph nodes or, at least, significantly reduce the differential diagnosis. CASE: A 70-year-old male presented with an ulcerated mass arising from the left tonsillar fossa and involving the anterior and posterior pillars. A biopsy of the tonsillar mass performed at an outside hospital was interpreted as a large cell undifferentiated carcinoma. Subsequently the patient developed systemic lymphadenopathy. A bone scan showed intense uptake within the medial tibial plateau of the left knee. FNA biopsy of the right axillary mass was interpreted at University of Cincinnati Medical College as a large cell lymphoma, multilobated type. Histologic and immunohistochemical studies of the lymph node confirmed the presence of multilobated B-cell lymphoma. lymphoma chemotherapy was initially successful but was discontinued due to toxicity. The patient died two months after the initial cytologic diagnosis of lymphoma. CONCLUSION: Multilobated lymphomas are an unusual variant of non-Hodgkin's lymphomas (mostly B-cell type). Cytology and immunocytochemistry are useful diagnostic procedures that can help to diagnose this relatively uncommon type of lymphoma and significantly reduce the possibility of misdiagnosis.

8/227. Acute leukemia following prolonged cytotoxic agent therapy.

    1. Nine patients in whom acute non-lymphoblastic leukemia (ANLL) developed following prolonged alkylating agent therapy are described. Five of the patients received no radiotherapy. The conditions treated were: Hodgkin's disease (four patients), primary amyloidosis, primary macroglobulinemia, malignant lymphoma, multiple myeloma, and carcinoma of the tonsil. 2. Prior to the advent of chemotherapy, this complication was not observed in large series of patients with lymphoproliferative disorders and multiple myeloma. However, the medical literature now contains at least 125 other detailed reports of ANLL developing after prolonged cytotoxic agent therapy. 3. multiple myeloma and Hodgkin's disease, both of which commonly have good responses to chemotherapy, predominate as the underlying diseases. However, 35% of the case reports involve patients with other illnesses, including 12 patients who did not have neoplasms. 4. More than half of the patients developing ANLL have received chemotherapy alone without radiotherapy. 5. At least half of the patients developing ANLL experienced long periods of significant cytopenia during therapy, often with documentation of bone marrow dysplasia. 6. The wide variety of drugs associated with this complication suggests that any cytotoxic agent may be leukemogenic. However, alkylating agents overwhelmingly predominate as the class of compounds which are most often associated with terminal ANLL. 7. The vast majority of patients reported in the literature with ANLL complicating underlying malignancies have received cytotoxic drugs for prolonged periods (median 3 1/2 years) and leukemia developed most commonly 3 to 5 years after the diagnosis of the underlying disease. Most of these patients benefited from therapy and survived longer (median 5 years) than historical control of untreated patients. 8. The leukemogenic potential in man of prolonged cytotoxic agents therapy, especially with alkylating agents, seems to be well established. This evidence admonishes against the prolonged use of these drugs in non-fatal disorders. 9. More accurate assessment of risk: benefit ratios awaits the results of prospective controlled studies. The results of these studies could also lead to significant modifications in recommendations for long-term maintenance therapy with cytotoxic agents. ( info)

9/227. dental caries after radiotherapy of the oral regions.

    Five cases of dental caries after radiation therapy of the oral regions for treatment of carcinomas are presented. The differences in clinical appearance and behavior between radiation caries and ordinary smooth-surface dental caries are described. The role of salivary gland irradiation and the resultant xerostomia in the development of these lesions is discussed. Some explanations are offered as to how these lesions develop in the light of current knowledge concerning plaque and the development of dental caries. Several measures that may be taken to reduce the incidence and severity of these lesions are suggested. ( info)

10/227. Giant fibrovascular polyp of the oropharynx.

    We describe a case of a giant fibrovascular polyp arising from the oropharynx and causing vague clinical symptoms. To our knowledge, this is the first description of an oropharyngeal fibrovascular polyp reported in the medical literature. The diagnosis was based on MR imaging findings, which showed the size and configuration of the polyp as well as the site of attachment. The patient underwent surgery, and the diagnosis was confirmed histologically. ( info)
