Résumé
Abstract The number of individuals with tattoos has been increasing worldwide, alongside with reports of complications varying from reactions to the injected pigments to infections caused by agents inoculated in the pigmentation process. The diagnosis of such unwanted events can be obtained through complementary non-invasive methods, preserving the maximum of the tattoo design. The authors present two cases of patients with warts on tattooing, and correlate their clinical aspects to in vivo and ex vivo dermoscopy, and to the findings in the histopathological examination, aiming to determine patterns that aid the diagnosis of these lesions without performing biopsy.

Abstract Alopecia areata is an autoimmune disease characterized by non-scaring hair loss. The onset in over 50-year-old patients is rare and has barely been studied. Cases of this disease have been retrospectively analyzed - according to clinical forms, extension, and associated diseases - to assess alopecia areata characteristics in a group of patients whose disease onset was after the age of 50. 30 patients were studied; a few of them presented with autoimmune-related diseases or family history. The disease onset after the age of 50 seems to have different characteristics from those found in young people.
