"String of pearls pattern": report of three cases of non clear-cell acanthoma
An. bras. dermatol; 92 (5,supl.1), 2017
Abstract The coiled and dotted vessels in a serpiginous arrangement or "string of pearls" is considered a classical vascular pattern associated with clear cell acanthoma.

DHEA and frontal fibrosing alopecia: molecular and physiopathological mechanisms
An. bras. dermatol; 91 (6), 2016
Abstract The transforming growth factor-beta 1 (TGFβ1) promotes fibrosis, differentiating epithelial cells and quiescent fibroblasts into myofibroblasts and increasing expression of extracellular matrix. Recent investigations have shown that PPAR (peroxisome proliferator-activated receptor*) is a ne...

Frontal fibrosing alopecia in association with Sjögren's syndrome: more than a simple coincidence

Abstract Frontal fibrosing alopecia is a distinctive form of scarring alopecia considered to be a clinical variant of lichen planopilaris. It predominantly occurs in postmenopausal women and has a slowly progressive course. It was first described by Kossard in 1994. Since then the number of reported case...
Lichen planopilaris-like eruption during treatment with tyrosine kinase inhibitor nilotinib
An. bras. dermatol; 91 (5,supl.1), 2016
Abstract Tyrosine kinase inhibitors are effective as a target therapy for malignant neoplasms. Imatinib was the first tyrosine kinase inhibitor used. After its introduction, several other drugs have appeared with a similar mechanism of action, but less prone to causing resistance. Even though these drugs...
