Primary Lymphoma (primary + lymphoma)
Selected AbstractsSonographic appearances of malignant lymphoma of the salivary glandsJOURNAL OF CLINICAL ULTRASOUND, Issue 9 2001Mayumi Yasumoto MD Abstract Purpose We undertook this retrospective study to describe the sonographic findings in patients with malignant lymphoma of the major salivary glands. Methods We reviewed the sonograms and medical records of 7 patients with histologically proven lymphoma of the parotid (3 patients) or submandibular glands (4 patients). Results Primary lymphoma was found in 1 parotid gland and 2 submandibular glands. The remaining 4 cases were secondary lymphomas. One patient had been diagnosed with Sjögren's syndrome and had been followed up with sonography. In parotid glands, both parenchymal and intraparotid nodal lymphomas were found. All submandibular gland tumors were parenchymal. Intraparotid nodal involvement appeared as multiple small nodules with relatively smooth margins, whereas the parenchymal parotid and submandibular gland lymphomas were larger (25 to 45 mm in longitudinal diameter) and showed various degrees of margin irregularity. All tumors were hypoechoic relative to the normal parenchyma. The primary parotid lymphoma and intraparotid nodal lymphomas had a homogeneous echotexture; the secondary parotid lymphomas and submandibular gland lymphomas were heterogeneous. One submandibular gland lymphoma showed intratumoral echogenic stripes. Neither calcification nor cystic degeneration was observed within the lesions. Conclusions Lymphomas of the salivary glands present a variety of sonographic appearances, ranging from multiple small, hypoechoic nodules to an irregularly shaped heterogeneous mass without cystic areas or calcifications. © 2001 John Wiley & Sons, Inc.

This review illustrates the widespread appearances seen on imaging methods (primarily CT and barium studies) with pathological correlation.

Jawad MD Abstract BACKGROUND: The low incidence of primary lymphoma of bone (PLB) has led to discrepancies in classification as well as difficulty in prognostication. The authors of this report used the Surveillance, Epidemiology, and End Results (SEER) database to analyze a large, population-based cohort of adult patients with this disease. The database provides a standardized classification and documentation of outcomes and enables a meaningful evaluation of prognostic factors. METHODS: The SEER database was used to identify all patients who were diagnosed with PLB from 1973 through 2005. Survival was analyzed with the Kaplan-Meier method, and the influence of clinical parameters on survival was analyzed with the log-rank test. A Cox proportional hazards model was used for multivariate analysis. RESULTS: Fifteen hundred adult patients with PLB were analyzed. The 5-year and 10-year survival rates for adult patients were 58% and 45%, respectively. Multivariate analysis revealed that younger age and localized disease were independent predictors of survival. It is noteworthy that the incidence of disease, as determined by the annual percentage change, increased during the study period (P < .05). CONCLUSIONS: This analysis of a large cohort of adults with PLB indicated that the only identifiable prognostic indicators were localized disease and younger age. The authors concluded that future treatment for patients with PLB need to be based on strict staging criteria and adherence to successful published protocols using collaborative clinical trials.
