ABSTRACT
The twenty-nail dystrophy or trachyonychia can be idiopathic or secondary to systemic diseases. Clinically it presents changes in the nail plate that can be divided in two variants: opaque trachyonychia or bright trachyonychia. Histologically, spongiotic changes are observed in the nail plaque. Diagnosis includes a good clinical, dermatological history, nail or systemic diseases that affect other members of the family, as well as hair, nails and mucous membrane examination. Onychomycosis should be ruled out, and sometimes a biopsy can be performed. Treatment can be based on observation only, of nail lacquer, local or systemic steroid and cyclosporine should be used in severe cases.REFERENCES
