Abstract
Optical coherence tomography (OCT) is a noninvasive and in vivo real-time diagnostic approach that allows for the visualization of skin architecture and cutaneous blood vessels. OCT provides a quick and useful diagnostic imaging technique for a number of nail disorders including psoriasis, glomus tumors, and subungual myxoid cysts and is a valuable addition to other noninvasive imaging tools such as dermoscopy and high-frequency ultrasound.
