“…It was first described by Baran and Perrin in 1995, 3 with a series of four patients who presented with the typical clinical appearance of longitudinal erythronychia. Since then, approximately 20 reports, describing a total of 205 cases, have been published on this diagnosis [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] (see Table 2). Atypical appearances, including longitudinal melanonychia, have been further described, especially in patients with pigmented skin.…”

Clinical and onychoscopic features of histopathologically proven onychopapillomas and literature update

et al. 2021

Background: Onychopapilloma is a benign tumor of the distal nail matrix and proximal nail bed with heterogeneous clinical presentations. It poses a diagnostic challenge because it could mimic subungual malignancies and inflammatory conditions. Clinical, onychoscopic, and histopathological clues play critical roles in diagnosis.Methods: We performed a retrospective chart review of onychopapilloma cases collected over 10 years, and characterized the clinical, onychoscopic, and histopathological features of onychopapilloma at an academic institution.Results: We obtained 17 biopsy-confirmed cases of onychopapilloma. Among our cases, we found manifestation of onychopapilloma as longitudinal erythronychia, longitudinal leukonychia, yellow-brown chromonychia, and longitudinal melanonychia.Long longitudinal or short splinter hemorrhages may be present. Distal fissuring with V-shaped notch, subungual keratotic mass, and onycholysis are other discernable features. Histopathological features include papillomatosis, epidermal hyperplasia, acanthosis of the distal nail bed, premature keratinization, matrix metaplasia, hyperkeratosis, and splinter hemorrhages; histopathological signs of malignancy were not observed in any of our cases.Conclusions: Onychopapilloma has polymorphic clinical and morphological features.Onychoscopic and histopathological studies are important to help exclude malignant mimickers. Consider onychopapilloma in the differential diagnoses of a monodactylous longitudinal streak in the nail, especially on the left thumb of an adult female.

“…Middle-aged women are the most affected, with the thumb being the prevailing location (Ramos Pinheiro et al 2018;Tosti et al 2016). • Clinical feature: Despite being frequently asymptomatic, it can disturb the handling of small objects and may have different clinical presentations (Ramos Pinheiro et al 2018;Sarkissian et al 2017;Tosti et al 2016). It generally presents as a single 1-8 mm wide band of longitudinal erythronychia originating in the distal lunula that invariably ends above a keratotic subungual papule, located in the underlying hyponychium (Fig.…”

“…An associated V-shaped onycholysis and fissuring at the distal edge of the nail may also be found. Less typical presentations include color variations (leukonychia, melanonychia, and reddish-yellow chromonychia) and isolated splinter hemorrhages (Ramos Pinheiro et al 2018;Haneke 2017;Sarkissian et al 2017;Kim et al 2016;Tosti et al 2016). • Onychoscopic manifestation: In general, onychoscopy allows better observation of the features (Figs.…”

Onychoscopy is becoming more and more frequently utilized for the diagnosis of nail disorders. It allows visualization of varying details of nails that can be diagnostic of several diseases, in particular periungual and subungual warts and onychomycosis. The onychoscopy criteria for majority of the inflammatory and infective nail disorders are evolving at a rapid pace. Distinctive dermoscopic signs that are exclusive to distal subungual onychomycosis and to traumatic onycholysis have also been described and allow a differential diagnosis from psoriasis. It has now become very essential for all the clinicians to learn the technique of

“…It commonly affects a single nail, mostly on the thumb, with longitudinal erythronychia beginning from the nail matrix and extending to the onychocorneal band 2 . Since the naming of the disease was finalized in 2000 by Baran and Perrin 3 , there have been only a limited number of reports on the disease 2,4,5 , and its characteristics have not been fully understood yet. To the best of our knowledge, only four cases have been reported in the Korean literature 6,7 .…”

A Rare Case of Onychopapilloma Presenting as a Longitudinal Erythronychia

Onychopapilloma is a rare benign neoplasm of the nail bed and the distal matrix. It is the most common cause of monodactylous localized longitudinal erythronychia. Splinter hemorrhage, onycholysis or distal splitting are usually accompanied due to the subungual keratotic growth located in the corresponding linear streak. A 50-year-old female was referred for the evaluation of 1-mm width of erythematous band on the left thumbnail. Distal onycholysis and splinter hemorrhages were seen along the streak with a thread-like horny papule beneath the edge of the nail plate. On histopathologic examination, papillomatosis and acanthosis were observed in the distal nail bed epithelium. The upper layers of the nail bed epithelium showed matrix metaplasia. The nail plate specimen revealed subungual hyperkeratosis with focal hemorrhage. The histopathological findings confirmed the clinical diagnosis of onychopapilloma. Herein, we report a rare case of onychopapilloma presenting as a longitudinal erythronychia. (Ann Dermatol 32(1) 74∼76, 2020
