High-frequency sonography and color Doppler in the management of pigmented skin lesions.
We aimed to evaluate high-frequency sonography (HFS) coupled with color Doppler in the management of pigmented skin lesions (PSL). HFS examination was performed in 111 patients with 130 PSL. A color Doppler study was conducted in 107 lesions, to assess intralesional vascularization. Imaging findings were compared with histologic diagnosis. In the case of melanoma, sonographic and histologic maximum thickness measurements were compared. HFS showed 114 of the 130 lesions. Among the detected lesions, HFS alone provided 100% sensitivity and 100% specificity in the distinction of melanoma/nevi from other lesions, and 100% sensitivity and 32% specificity in the distinction of melanomas from nonmelanoma lesions. Sonographic and histologic measurement of melanoma thickness strongly correlated (r > 0.96, p < 0.001). Color Doppler detection of intralesional vessels had a 100% specificity and 34% sensitivity in the distinction of melanomas from other PSL. HFS coupled with color Doppler is a simple, reliable tool for PSL management.
