A new study has identified several characteristics that can help to detect seborrheic keratosis (SK)–like melanomas using dermoscopy, including the presence of the blue-black sign, pigment network, pseudopods or streaks, and/or a blue-white veil. Identification of these characteristics can help clinicians to recognize and diagnose these difficult melanoma cases. The results of the study were published in JAMA Dermatology.
“Many practitioners, even nondermatologists, remove typical looking SKs without the use of dermoscopy and without confirming the diagnosis with pathologic analysis,” wrote Cristina Carrera, MD, PhD, of the department of dermatology at the Hospital Clínic de Barcelona in Spain, and colleagues. “All lesions of patients with numerous SKs need to be assessed dermoscopically to increase the possibility of detecting the odd SK-like melanoma.”
SKs are commonly occurring skin neoplasms that are frequently treated without biopsy. However, studies have shown that a percentage of these neoplasms may, in fact, be melanomas. Dermoscopy can be used to help confirm the diagnosis of SK.read the original full article
