What Conditions Can Trachyonychia Indicate?

Atopic Dermatitis

Eczema or atopic dermatitis can cause an affected individual to develop trachyonychia. Atopic dermatitis is a disease that affects the skin and causes the development of dry, scaly patches on a patient's skin. These dry and scaly patches on the skin are often described as extremely itchy and are responsible for intense discomfort that occurs in affected individuals. Atopic dermatitis can happen in a child as early as two or three months old. Approximately ninety percent of atopic dermatitis patients will experience manifestations before they reach half a decade of life. Milder manifestations of atopic dermatitis continue from childhood into adulthood in around half of all patients. Atopic dermatitis happens when the skin's ability to retain moisture becomes impaired. Without the protective moisture barrier function of the skin, external factors or changes can cause inflammatory lesions. Trachyonychia occurrence in eczema is the result of the individual's nail matrix being infiltrated by eczematous change. These changes in the skin around the nail and nail bed cause an interruption of nail synthesis, resulting in trachyonychia and other conditions that affect the nails.
