What Is Dermatology - Tinea Unguium
Tinea Unguium
Tinea unguium is presented as white patch on the lateral and distal undersurface of the nail and nail bed.
The mode of transmission is person to person via direct contact ( family member) or via fomite.
Tinea unguium commonly involve the toenails than fingernails.
The white patch consists of sharply demarcated borders. The white patch may develop into black hue or brown hue.
Tinea uguium is associated with infection of dermatophytes of the nail. The infection may last for weeks or months with no spontaneous remission.
The nail may become friable, cracked, thickened and opaque. The nail will raise due to the hyperkeratotic debris in the hyponychium.
There will be sharply demarcated white streak at the distal part of the nail margin which extend proximally. The white streak consists of keratinaceous debris and air.
Patient typically complain of painful toenail due to pressure from the shoes or ulceration of the underlying nail bed as well as due to secondary bacterial infection.
Unilateral fingernails involvement are common form if fingernails are affected and typically present in the forms of two feet and one hand.
The nail will lose its protective function. Tinea unguium is worse in diabetic patient and immunocompromised patient.
The differential diagnosis of tinea unguium may include psoriasis, trauma to the nail, Reiter syndrome, onychogryphosis, psoriatic nail, congenital nail dystrophies and keratoderma blennorrhagicum as well as pincer nail.
Tinea unguium is detected by the present of fungi in the culture as well as direct microscopy examination of nail clipping in potassium hydroxide solution.
The treatment may include consideration of removal of the dystrophic nail as well as prescription of terbinafine or systemic antifungal.
