Objective. The purpose of this study was to evaluate the appearance of primary peripheral soft tissue lymphoma on high-resolution ultrasonography. Methods. We retrospectively studied the sonograms of 12 patients (5 female and 7 male; age range, 1290 years; mean, 55 years) with soft tissue lymphoma. All lesions were palpable and in the salivary glands, trunk, upper limb, or lower limb, and the diagnosis was proved by biopsy or open surgery. For each lesion, sonograms were obtained by gray scale and color Doppler ultrasonography. Results. The gray scale imaging showed relatively homogeneous hypoechogenicity in 11 patients and homogeneous hyperechogenicity in 1 patient. The tumors appeared as big masses in 5 patients, nodal or confluent nodes in 3, small disseminated nodules in 2, a myositis type in 1, and a panniculitis type (homogeneous echogenic infiltrate in a subcutaneous fat layer) in 1. Conclusions. In patients with a soft-tissue mass, routine plain radiography and high-resolution ultrasonography including color Doppler ultrasonography are recommended before further evaluation with ultrasonographically guided biopsy.
