Morphologic Features of Cutaneous T-Cell Lymphomas Using Dermoscopy and High Frequency Ultrasound.

Area of Science:

• Dermatology
• Oncology
• Medical Imaging

Background:

• Cutaneous T-cell lymphoma (CTCL) diagnosis is often delayed, requiring expert evaluation and biopsy.
• Non-invasive tools like dermoscopy and high-frequency ultrasound (HFUS) are being explored for earlier detection.
• Current diagnostic pathways for CTCL can be lengthy and invasive.

Purpose of the Study:

• To prospectively evaluate dermoscopy and HFUS for diagnosing CTCL patches and plaques.
• To compare dermoscopic and HFUS findings in CTCL with those in atopic dermatitis (AD) and psoriasis.
• To assess the utility of these non-invasive methods in differentiating early-stage CTCL.

Main Methods:

• Prospective study involving thirteen patients with established diagnoses of CTCL, psoriasis, or AD.
• Dermoscopic examination of skin lesions.
• High-frequency ultrasound (HFUS) assessment of skin thickness.

Main Results:

• Dermoscopy revealed specific features like spermatozoa-like structures and white scales that may help distinguish CTCL from AD.
• HFUS demonstrated increased epidermal thickness in CTCL and psoriasis compared to AD.
• These findings suggest potential for non-invasive diagnostic aids.

Conclusions:

• Dermoscopy is a valuable tool for aiding CTCL diagnosis.
• HFUS may supplement dermatologic assessment for CTCL, but requires further standardization.
• Non-invasive techniques offer a promising adjunct to traditional diagnostic methods for CTCL.
