retronychia proximal ingrowing of the Nail Plate
Journal of The American Academy of Dermatology, 2008Co-Authors: David De Berker, Bianca Maria Piraccini, Bertrand Richert, Josette André, Edith Duhard, Robert BaranAbstract:Background Proximal Nail fold inflammation can be caused by many diseases and has not previously been recognized as a result of posterior embedding of the Nail. We describe a new pattern of ingrowth that we have termed retronychia ("retro"—Latin for backwards; "onychia"—Greek for Nail). The term describes a combination of proximal Nail Plate ingrowth into the proximal Nail fold which is associated with multiple generations of Nail Plate misaligned beneath the proximal Nail. Objective To describe a new pattern of Nail ingrowth which causes a specific form of proximal Nail fold paronychia. Methods Collective cases were reported to a European Nail Society expert group. Results Persistent proximal Nail fold inflammation can result from an episode of trauma that disturbs longitudinal Nail growth and results in reverse embedding of the Nail Plate. This can cause pain, inflammation, and granulation tissue formation, and is typically relieved by avulsion and antiinflammatory treatment. Limitations We cannot demonstrate causality between the proposed precipitants and the clinical features. Conclusion Retroncyhia represents proximal ingrowth of the Nail that occurs when the Nail embeds backwards into the proximal Nail fold. Nail Plate avulsion with supplementary medical management is curative.

idiopathic trachyonychia twenty Nail dystrophy a pathological study of 23 patients
British Journal of Dermatology, 1994Co-Authors: Antonella Tosti, Federico Bardazzi, Bianca Maria Piraccini, Pier Alessandro FantiAbstract:Summary We report the clinical features and pathological findings in 23 patients with idiopathic trachyonychia (twenty-Nail dystrophy). Clinically, the Nail changes in the majority of patients consisted of the typical ‘sandapered’ appearance, with a rough, Iustreless Nail Plate. In some, however, the Nail Plate abnormality was less severe, with numerous small, superficial pits, which imparted a shiny appearance to the surface of the Nail. Histology of Nail biopsy specimens showed spongiotic changes in 19 patients, psoriasiform features in three, and features of lichen planus in one patient. The mean follow-up of these patients was 2 years, during which time none developed alopecia areata or mucocutaneous lesions. Idiopathic trachyonychia is therefore a consequence of several inflammatory disorders, which produce a disturbance of Nail matrix kinetics. The course of the inflammation and the extent of the inflammatory process within the Nail matrix produce two different patterns of Nail Plate surface abnormalities.

histological analysis of the Nail Plate in the diagnosis of melanonychia and other Nail pigmentation
2017Co-Authors: Beth S. RubenAbstract:Melanocytic activation is a common cause of pigmentation of the Nail Plate and consists of melanin production without a proliferation of melanocytes. Melanocytic proliferations (lentigo, nevi, and melanoma) often produce a solitary longitudinal pigmented band. Other causes of Nail Plate pigmentation: pigmented squamous cell carcinoma, pigmented onychomatricoma, onychocytic matricoma, pigmented onychomycosis, and Nail Plate hemorrhage. Nail clipping can serve as a less invasive screening procedure for identifying the cause of Nail Plate discoloration. Fontana–Masson staining is useful in identifying melanin. Benzidine stain can be used to identify hemoglobin.
