To the Editor, We read with interest the excellent article titled “Use of dermoscopy in the diagnosis of temporal triangular alopecia” by Campos et al.1 However, we take issue with their statement that the incidence of congenital triangular alopecia has been estimated at 0.11%.2 Taken at face value, readers may assume that 0.11% of the general population have congenital triangular alopecia. The...

BACKGROUND Permanent alopecia after bone marrow transplantation is rare, but more and more cases have been described, typically involving high doses of chemotherapeutic agents used in the conditioning regimen for the transplant. Busulfan, classically described in cases of irreversible alopecia, remains associated in recent cases. The pathogenesis involved in hair loss is not clear and there are...

Alopecia areata is a hair loss disorder in humans, dogs and horses with a suspected autoimmune aetiology targeting anagen hair follicles. Alopecia areata is only sporadically reported in cows. Recently, we observed several cases of suspected alopecia areata in Eringer cows. The aim of this study was to confirm the presumptive diagnosis of alopecia areata and to define the clinical phenotype and...

and male alopecia [1–4] . The prerequisite for delivering appropriate patient care is an understanding of the pathologic dynamics of hair loss and a potential multitude of causal relationships. Once the diagnosis is certain, treatment appropriate for that diagnosis is likely to control the problem. Ultimately, the best way to alleviate the emotional distress related to hair loss is to effective...

INTRODUCTION Androgenetic alopecia (AGA) is the most common form of hair loss. Clinically observed hair loss is due to the continuous miniaturization of affected hair follicles. Genetic factors and androgenic factors especially dihydrotestosterone (DHT), which is a testosterone tissue metabolite, play major roles in the pathogenesis of AGA. However, expert opinions about the usefulness of DHT i...

Frontal fibrosing alopecia (FFA), a scarring type of alopecia, developed in two patients with a history of alopecia areata (AA). Both patients had biopsies to confirm this interesting series of pathology. Etiology and pathogenesis of this AA-to-FFA sequence will be discussed.

OBJECTIVES The aim of this research was to describe the cases of TNF-α antagonist-related alopecia reported in the French Pharmacovigilance Database (FPVD) and to investigate the association between exposure to TNF-α antagonists and occurrence of alopecia. METHODS All spontaneous reports of TNF-α antagonist-related alopecia recorded in the FPVD between January 2000 and April 2012 were colliga...

A 20-months-old infant was admitted with prolonged fever, bilateral non-purulent conjunctivitis, strawberry tongue, lip cracking and maculopapular rash. Left branch coronary aneurysm formation was detected in Color-Doppler echocardiography. The diagnosis was Kawasaki disease. After 6 weeks, he had alopecia totalis. Although, alopecia areata has been seen in Kawasaki disease, but alopecia totali...
