Temporal triangular alopecia, also referred as congenital triangular alopecia, is
an uncommon dermatosis of unknown etiology. It is characterized by a
non-scarring, circumscribed alopecia often located unilaterally in the
frontotemporal region. It usually emerges at ages 2-9 years. Alopecia areata is
the main differential diagnosis, especially in atypical cases. Dermoscopy is a
noninvasive procedure that helps distinguish temporal triangular alopecia from
aloepecia areata. Such procedure prevents invasive diagnostic methods as well as
ineffective treatments.
FUNDAMENTOS - Observa-se comorbidade psiquiátrica em 40% dos pacientes dermatológicos adultos, sendo a acne vulgar de interesse da psicodermatologia por ter entre suas complicações seqüelas psicossociais. OBJETIVOS - Estabelecer a relação entre acne e o status de bem-estar. MÉTODOS - Estudo de caso-controle com dados coletados a partir do Índice de Bem-Estar da Organização Mundial da Saúde, por meio de entrevistas com dois grupos de 50 acadêmicos de medicina, sendo um com acne e outro sem acne. RESULTADOS - Foi verificado que 26% dos acadêmicos do grupo de casos e 24% do grupo controle apresentaram de 0 a 4 pontos em pelo menos um dos itens questionados. CONCLUSÕES - Apesar de a maioria dos pacientes apresentar atitudes e sentimentos desencadeados pela acne, não se demonstrou associação estatisticamente significativa entre essa dermatose e baixo nível de bem-estar.
Muir-Torre Syndrome is defined by the coexistence of sebaceous skin tumors and
internal malignancies. Mutations in the DNA mismatch repair genes are found in the
inherited form of the disease, resulting in the absence of crucial enzymes involved
with DNA replication process. This case describes a patient with sebaceous adenoma
and colorectal carcinoma, meeting the criteria for Muir-Torre Syndrome. The
immunohistochemical analysis of the skin lesion was an important tool to confirm the
diagnosis, as it revealed nuclear negativity for MSH2 and MSH6.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
