Dermoscopy of acral angioma serpiginosum
Angioma serpiginosum (AS) is an unusual vascular disorder that typically affects female patients, begins in childhood and stabilizes in adulthood and not frequently involve acral skin. We herein present a 13 year-old girl with an asymptomatic erythematous punctuate first noticed on the right palm three years ago, with a proximal serpiginous progression up to the forearm. On examination there was a nonblanching erythematous punctuate on the palm and the inner aspect of right hand and forearm. Dermoscopy showed an erythematous parallel ridge pattern with some red globules and dots spreading on a linear arrangement, and the acrosyringia openings were not affected. Histopathological study showed dilated capillaries in the dermal papillae. This feature is consistent with angioma serpiginosum (AS). To the best of our knowledge, this is the first report that shows a dermoscopic image of a palmar AS. The dermoscopic pattern described in this case could aid in the diagnosis of AS and could add a value in the differential diagnosis with vascular lesions on acral skin

Acral Persistent Papular Mucinosis: is it an under-diagnosed disease?
Acral persistent papular mucinosis is a subtype of localized lichen myxedematosus. It presents as acrally located papules with a benign, but persistent course. It is a scarcely reported disease. We present a female with both the clinical and histopathological described criteri

Aplicação da dermatoscopia no auxílio diagnóstico da ocronose exógena Use of dermoscopy for diagnosis of exogenous ochronosis
A ocronose exógena consiste em hiperpigmentação crônica de áreas previamente tratadas com agentes tópicos como: a hidroquinona, a resorcina, os antimaláricos e o fenol. O diagnóstico precoce permite suspender prontamente o agente causador, uma vez que as opções terapêuticas disponíveis são escassas e com resultados insatisfatórios. Reportam-se três casos de ocronose exógena na face, diagnosticados pela dermatoscopia. O estudo dermatoscópico evidenciou estruturas amorfas de coloração cinza-enegrecido, algumas obliterando as aberturas foliculares. O exame histopatológico corroborou o diagnóstico<br>Exogenous ochronosis consists of chronic hyperpigmentation of areas previously treated with topical agents such as hydroquinone, resorcinol, antimalarials and phenol. Early diagnosis allows to promptly suspend the causative agent and it is imperative since the available therapeutic options are scarce and have presented so far unsatisfactory results. Three cases of exogenous ochronosis on the face which were diagnosed with the use of dermoscopy are presented. Dermatoscopy showed blackish-gray amorphous structures, some obliterating the follicular openings. Histopathological examination confirmed the diagnosi
