“…6 The location of a CPA outside the oral cavity and the gastrointestinal tract is uncommon, having been described in only 3 patients with lesions in the eyelids 9 and in another of subungual location. 10 We present a case of CPA in a young male with no history of trauma, drugs or comorbidities, in a non-mucosal epithelial surface and therefore suggest that this entity may be more frequent and widespread than is apparent from the literature. Prevalence and management of chronic nodular prurigo (CNPG) in Brittany (France): estimation by matching two databases Chronic nodular prurigo (CNPG) is the nodular subtype of chronic prurigo, a skin disease due to neuronal sensitization to itch and development of an itch-scratch cycle.…”

highlighting broader clinical variability of this type of DEB too. Furthermore, our data indicate that single glycine deletions in COL7A1's THD may have the same molecular effect as glycine substitutions. Whether all single glycine deletions would exert a dominant negative effect or some would be recessive, as is the case with glycine substitutions, 2 needs to been seen. Finally, this study emphasizes the importance of careful examination of relatives and co-segregation analysis in case of unknown or unexpected clinical and molecular findings.

“…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.…”

“…3 Subsequent reports have described diverse presentations, including longitudinal melanonychia, longitudinal leukonychia, yellow-brown chromonychia, splinter hemorrhages, distal nail plate fissuring, and onycholysis. [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] It could easily mimic worrisome diagnoses, including melanoma and squamous cell carcinoma. Misdiagnosis could cause significant patient distress and anxiety.…”

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.
