ABSTRACT

Abstract

Pili torti also known as ‘twisted hairs’ (Latin: pili=hair; torti=twisted) is a rare, congenital or acquired clinical presentation, in which the hair shaft is flattened at irregular intervals and twisted 180º along its axis. It is clinically characterized by fragile, brittle, coarse and lusterless hairs, due to uneven light reflection on the twisted hair surface. Pili torti may be associated with neurological abnormalities and ectodermal dysplasias. There is no specifi c treatment for this condition, but it may improve spontaneously after puberty. We report a case of pili torti in a child who presented fragile, brittle, diffi cult to comb hair. The patient had no comorbidities.

ABSTRACT

O fibroqueratoma digital adquirido é tumor fibroepitelial benigno, raro, que, tipicamente, se apresenta como nódulo solitário assintomático nos quirodáctilos e pododáctilos. Relata-se o caso clínico de uma paciente do sexo feminino que apresentava duas lesões de fibroqueratoma digital no quarto e no segundo quirodáctilos esquerdos.

ABSTRACT

Apresenta-se caso clínico de carcinoma espinocelular subungueal (CEC subungueal) em paciente do sexo masculino de 89 anos, cuja lesão se localizava na dobra medial do primeiro quirodáctilo esquerdo há quatro anos. Esta apresentação se justifica pela raridade da doença na localização subungueal e pelo fato de se atentar para o diagnóstico diferencial com lesões benignas valorizando o sintoma dor, capaz de sugerir o diagnóstico que, quando precoce, representa melhor prognóstico e menor morbidade. Discutem-se também as abordagens terapêuticas mais indicadas, baseando-se em trabalhos de revisão da literatura, com radioterapia, cirurgia micrográfica de Mohs e amputação.


A clinical case of subungual squamous cell carcinoma, in which a tumor had been located in the medial fold of the left thumb for 4 years, is described in a 89-year-old male patient.The objectives of this study are to draw attention to the rarity of the subungual location of the tumor – highlighting the differences in diagnosis compared with benign lesions – and the importance of pain as a symptom, which may help diagnose the condition early and facilitate a better prognosis and lower morbidity. Additionally, we discuss the more frequently used therapeutic approaches, based on a review of the literature on radiation therapy, Mohs Micrographic Surgery and amputation.

ABSTRACT

Apresenta-se caso clínico de variante rara de dermatofibroma (tipo aneurismático) em paciente do sexo feminino de 72 anos de idade, cuja lesão se localizava na dobra flexural do membro superior direito, resultante de proliferação mesenquimal associada à vasos sanguíneos e hemorragia tecidual, com características histológicas próprias e bem definidas. Os objetivos desta descrição foram a raridade da lesão e a importância que ela assume, do ponto de vista histopatológico, quando comparada no diagnóstico diferencial com outros tumores benignos e malignos e a terminologia utilizada atualmente.
