The Coexistence of Trachyonychia and Mucocutaneous Lichen Planus: A Case Report

Cureus. 2023 Nov 6;15(11):e48415. doi: 10.7759/cureus.48415. eCollection 2023 Nov.


Trachyonychia is an uncommon finding characterized by the nails having a uniform and simultaneous presence of fragility, excessive longitudinal growth, ridging, and loss of luster. Usually, twenty-nail dystrophy (TND)/trachyonychia is an idiopathic condition, but sometimes dermatoses such as alopecia areata, lichen planus, and psoriasis are found to be associated with it. We report a case of trachyonychia/TND in a young male with the concomitant presence of cutaneous lichen planus of hypertrophic type, reticular oral lichen planus, and nail lichen planus, which was diagnosed with the aid of dermoscopy and histopathology. Many cutaneous disorders, systemic illnesses, and infections can cause nail dystrophy; therefore, a proper diagnosis is crucial to treat the underlying cause. Early intervention improves patients' prognosis and alleviates their psychological strain and cosmetic concerns.
