Non-pigmented basal cell carcinoma: dermoscopy plus reflectance confocal microscopy provide diagnostic clues and high-frequency ultrasound detects surgical boundary.

This article discusses the diagnosis and treatment of non-pigmented basal cell carcinoma (BCC), the most common type of skin malignancy. Non-pigmented BCC can be challenging to diagnose due to its lack of pigment. The article describes a case study of a 59-year-old female with non-pigmented BCC on her nose. The diagnosis was made using dermoscopy, reflectance confocal microscopy (RCM), and high-frequency ultrasound (HFUS). Mohs micrographic surgery was performed to remove the tumor, guided by HFUS to accurately delineate the surgical boundary. The article concludes that noninvasive imaging techniques, such as dermoscopy, RCM, and HFUS, can aid in the diagnosis and treatment of non-pigmented BCC. [Extracted from the article]
