Onychauxis presents with thickened nails without deformity, and this simple thickening may be the result of trauma, acromegaly, Darier's disease, psoriasis, or pityriasis rubra pilaris, or, in some cases, hereditary.

Onychauxis frequently shows up clinically as discoloration, subungual hyperkeratosis, and loss of nail plate translucency.

[3] The recommended first treatment is periodic partial or complete debridement of the thickening nail plate.

Other potential treatments that could be helpful are urea pastes with a 40% or greater concentration, electric drills, and nail avulsion.

In complex situations or those with recurrences, chemical or surgical matricectomy may be used as a last resort to accomplish permanent ablation of the affected nail plate.
