<\/span>What Causes Onicopapilloma?<\/span><\/h2>\nThe cause of onychopapilloma is unknown.<\/p>\n
<\/span>What are the clinical features of onychopapilloma?<\/span><\/h2>\nOnychopapilloma usually produces a longitudinal line on a red nail (erythronychia), extending from the lunula<\/span> to the tip of the nail.<\/p>\n\n- \n
\n- White longitudinal stripes (leukonychia<\/span>) or brown longitudinal stripes (melanonychia<\/span>) can also occur.<\/li>\n
- the distal<\/span> the tip of the nail may split or lift (onycholysis<\/span>)<\/li>\n
- A warty<\/span> growth may be evident under the nail (subungual<\/span> keratosis<\/span>)<\/li>\n
- Splinter hemorrhage<\/span> (linear<\/span> streak of blood under the nail) is common.<\/li>\n
- Dermoscopy of the free edge of the nail plate shows a small area of subungual scale<\/span>.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n

<\/span>How is onychopapilloma diagnosed?<\/span><\/h2>\nThe diagnosis can be suspected clinically, but as evil one<\/span> lesions under the nail could look similar, it is important to keep the injury under review and perform the nail biopsy<\/span> if there is an enlarged lesion<\/p>\nHistology<\/span> of a nail clipping showing an area of asymmetric<\/span> dyskeratosis<\/span> and papillomatosis<\/span>.<\/p>\nLongitudinal biopsy of the nail shows a papillomatous<\/span> nail bed with layers of hyperkeratosis<\/span> and an absent granular layer<\/span>. Pigmentation<\/span> if present, it is due to melanocyte<\/span> activation.<\/p>\n\n
