The remaining 4 cases were secondary lymphomas. One patient had been diagnosed with Sj\u00f6gren'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.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>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. \u00a9 2001 John Wiley &amp; Sons, Inc.
