“…9 A lobulated, oval, or irregular shape and anechoic areas have been described in half of cases of pleomorphic adenomas and in WarthinÕs tumors. 9 The role of color Doppler in the evaluation of salivary gland tumors is controversial. In an analysis of 56 patients with salivary gland lesions assessed prospectively using color and power Doppler sonography, Bradley et al 10 found that the risk of malignancy increases by a third when color Doppler sonography shows increased intratumoral vascular resistance (resistance index > 0.8 and pulsatility index > 1.8), with a positive predictive value of 97%, sensitivity of 76%, and specificity of 86%.…”

We report the case of an extranodal non-Hodgkin's lymphoma mimicking a benign tumor in the left parotid gland of a 71-year-old woman. The clinical presentation of the painless, mobile mass was suggestive of a benign parotid tumor such as an adenoma. The intraglandular tumor appeared sonographically as a well-circumscribed, hypoechoic, homogeneous, lobulated mass with mild distal sound enhancement. Power Doppler sonography showed marked intratumoral vascularization. The tumor was resected by lateral lobectomy of the parotid gland and was found histopathologically to be a diffuse large B-cell lymphoma.

“…Vascularization in pleomorphic adenomas is often poor or absent (even when the sensitive power Doppler mode is used) (Fig 21) but may be abundant (71,73,74). After inadequate surgery, pleomorphic adenomas often recur, usually multifocally (75).…”

“…At US, Warthin tumors are oval, hypoechoic, well-defined tumors and often contain multiple anechoic areas (Figs 22, 23) (25,74,78,80). Warthin tumors are often hypervascularized (Fig 24) but may also contain only short vessel segments.…”

“…Lobulated shape in pleomorphic adenomas and anechoic areas in Warthin tumors, although common, are not pathognomonic and may be found in many other lesions, including malignancies (73,74) (Fig 25). For example, macroscopic cystic structures, which appear as anechoic areas at US, may occur in other benign tumors (pleomorphic adenoma, basal cell adenoma), in malignant tumors (mucoepidermoid carcinoma, acinic cell carcinoma), and in an abscessed or necrotic metastatic node; in addition, benign lymphoepithelial lesions in HIV-positive patients may have the appearance of solid-cystic nodules (Fig 25) (3,35,72,74,82-86).…”

“…1,2 The sonographic appearance is nonspecific, with benign and malignant tumors being most commonly hypoechoic. 3,4 Although malignancy has to be considered if the margins are irregular, if posterior shadowing is visualized, or if there is heterogeneous internal echogenicity, 5 these features are rarely observed. In addition, even neoplasms of the same histologic type, such as lymphoma, can have varying sonographic appearances, ranging from small, hypoechoic nodules to irregularly shaped, heterogeneous masses.…”

Objective. To evaluate the utility and safety of ultrasound-guided fine-needle aspiration of the salivary glands for diagnosis of focal masses in the salivary glands, including the prevalence of nondiagnostic sampling, the impact of the presence of a cytologist during the procedure, and the usefulness of flow cytometry. Methods. A retrospective analysis of 43 ultrasound-guided fine-needle aspirations of the salivary glands from 36 lesions in 33 patients was performed. Fine-needle aspirations were obtained under sonographic guidance, and 1 to 6 punctures were made with 20-to 25-gauge needles. Ultrasound-guided fine-needle aspirations obtained in the presence of a cytologist were compared with those performed without a cytologist regarding the adequacy of the specimen and the number of punctures performed. Postprocedural complications and the frequency with which flow cytometry was performed were noted. Cytopathologic diagnosis was correlated with clinical follow-up (n = 33) and surgical pathologic findings (n = 10). Results. Cytologic diagnosis was made in 31 (94%) of 33 patients, confirming a neoplastic process in 18 (50%) of 36 and a non-neoplastic process in 16 (44%) of 36. Although the presence of a cytologist at the bedside resulted in a higher prevalence of diagnostic sampling (P < .05), it did not alter the number of punctures performed (mean, 3 punctures). No complications were encountered except for pain in 2 patients. Flow cytometry was helpful in 8 (22%) of 36 patients. Conclusions. Ultrasound-guided fine-needle aspiration of the salivary glands is a safe procedure with a low prevalence of nondiagnostic sampling. Approximately 44% of patients can be spared surgical intervention through diagnosis of a non-neoplastic process. The presence of a cytologist increases the likelihood of obtaining a diagnostic sample. Flow cytometry was helpful in 22% of patients.
