Usefulness of ultrasonography in assessment of skin lesions of cutaneous T-cell lymphoma

Cutaneous T-cell lymphoma (CTCL) poses a challenge in terms of diagnosis and assessment of disease progression. High-frequency ultrasound (HFUS) is a non-invasive imaging modality used for evaluating dermal changes, including the assessment of infiltrative intensity in CTCL. HFUS encompasses the assessment of infiltrative intensity, visualization of tumor characteristics, and monitoring of disease progression and treatment response. By providing detailed and precise information regarding the affected skin layers, HFUS contributes to the diagnostic process and aids in the management of this complex disease. Herein, we present the case of a 79-year-old male diagnosed with mycosis fungoides (MF), whose disease was confirmed by HFUS examination during PUVA therapy.
