    Nail Apparatus Melanoma: Experience of 10 Years in a Single Institution
    (2019) LEE, Desiree Ji Re; ARBACHE, Samia Trigo; QUARESMA, Maria Victoria; NICO, Marcello Menta Simonsen; GABBI, Tatiana Villas Boas
    Background: Nail apparatus melanoma (NAM) is rare. The higher mortality reported in the literature is most likely due to advanced disease associated with delayed diagnosis and treatment. Objective: All patients diagnosed with NAM were followed at a single reference center during a period of 10 years, with emphasis on dermatological and histological findings. Clinical outcomes were included. Methods: A retrospective review of medical records, photographs, and histopathological examination. Results: 73.7% of the patients were female and their mean age was 47 years. Caucasian and African-American patients had a similar incidence (47.4%). There was only 1 Asian patient in this study (5.3%). All patients presented with nail plate pigmentation. The mean prediagnosis duration was 33 months. A total of 63.2% patients had in situ melanoma and an average Breslow index of 2.18 mm in invasive cases. Fifteen patients underwent conservative surgery and 3 underwent phalanx amputation. All patients survived, and 4 have had more than a 5-year follow-up. Conclusion: In situ lesions showed longitudinal bands or total melanonychia with no nail dystrophy. Invasive cases presented with dystrophic lesions (longitudinal splitting of the nail). Conservative surgery provides a good option without worsening the prognosis. All dermatologists should be aware of early signs of NAM, since prognosis depends on early treatment.

    Squamous Cell Carcinoma Arising in Discoid Lupus Erythematosus of the Nail Unit
    (2023) YENDO, Tatiana Mina; GABBI, Tatiana Villas Boas; NICO, Marcello Menta Simonsen
    Introduction: Discoid lupus erythematosus can affect periungual tissues leading to onychodystrophy. Squamous cell carcinoma can occur in persistent scars of discoid lupus; this rare occurrence has not yet been reported on the nail unit. Case presentation: we report a case of squamous cell carcinoma occurring on the distal phalanx of the thumb in a patient with longstanding periungual discoid lupus on several fingernails. Discussion: Periungual discoid lupus erythematosus is rare. The scars caused by this disease can very rarely develop into squamous cell carcinoma. This is the first report of this occurrence at the periungual tissues.
