"Pink glow": A new sign for the diagnosis of glomus tumor on ultraviolet light dermoscopy.

Glomus tumors are usually benign hamartomas, which are painful, small, and uncommon. They are usually subungal in location but may occur at other sites. A female patient presented to the outpatient department with painful swelling over the nail matrix of her right index finger. Here, we describe the use of a videodermosope having white light, polarized light, and ultraviolet (UV) light in the localization of glomus tumors that revealed a pinkish glow on UV light examination suggesting the vascular nature of the tumor. Thus, videodermoscopy can be used as an outpatient department procedure to confirm the diagnosis of glomus tumors.
