Abstract:
Longitudinal melonychia is a brown streaking of the nailbed. It is often benign but can be a subungual melanoma. Subungual melanoma is a rare malignancy. Diagnosis is often delayed, resulting in a higher staging and poorer prognosis than other cutaneous melanomas. We provide an update on the evaluation of longitudinal melonychia and biopsy technique.

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

01:14Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
