Abstract:
We evaluated superficial soft-tissue lymphomas on high-resolution ultrasonography (HRUS) in 43 patients (17 women, 26 men; mean, 59.7 y; range, 12 to 90 y), with 1- to 97-month follow-up. Clinical presentations, tumor location and morphology, echogenicity on HRUS and color-encoding grades on Doppler ultrasonography (CDUS) were assessed. Clinical presentations did not significantly differ with tumor location or morphology. Types of lymphoma did not significantly differ in echogenicity, although most were hypoechogenic. On CDUS, most lymphomas were hypervascular, but grades did not significantly depend on the type of tumor. On Kaplan-Meier analysis with log-rank testing, survival did not differ by age (divided at 65 y), sex, tumor location or size (cut-off, 5 cm), CDUS grade or pathology. Survival was significantly related to clinical presentation (p < 0.0095) and tumor morphology (p < 0.0354). HRUS and CDUS were good modalities to detect the masses and provided important pretreatment information.
