Median nail dystrophy, also known as dystrophia unguis mediana canaliformis, median canaliform dystrophy of Heller,: 788
Thumbs, which are the most commonly involved, usually show an enlarged lunula resulting probably from repeated pressure applied on the base of the nail.[1]: 657
Signs and symptoms
Median nail dystrophy presents as gifts that resemble an upside-down fir tree or Christmas tree because to tiny fissures or cracks that break toward the nail edge or extend laterally from the center canal.[3] Usually symmetrical, the ailment primarily affects the thumbs, though it can also affect other fingers or toes.[4] There may be lunula enlargement, redness, and thickening of the proximal nail fold.[5]
Causes
Although it is an acquired illness, there have been reports of familial clustering of instances.[4] The illness most likely stems from a transient flaw in the matrix that prevents nails from growing.[6] One component that has been identified as causal is trauma.[7]
Diagnosis
Clinical findings are frequently the only basis for diagnosis.[8] Parakeratosis, or the buildup of melanin inside and between the keratinocytes in the nail bed, is typically seen in histopathology.[3]
Treatment
For median nail dystrophy, treatment is frequently not required.[8] Normalcy usually returns to affected nails on its own, either when medication is stopped or after a traumatic event.[9][7] Triamcinolone acetonide injected directly into the proximal nail fold or topical ointments have been effectively used in the treatment of median nail dystrophy, though this is not usually advised.[6][10]
