Background: Alopecia Areate (AA) is a recurrent non-scarring patchy hair loss of autoimmune origin in a genetically susceptible individual although environmental factors may be contributory. The aim of this study is to evaluate serum iron and ferritin levels in patients with AA. Methods: Fifty patients of AA and 50 age and sex matched control subjects without any hair loss were studied. Results...
Background: Alopecia Areata (AA) is a non-scarring, autoimmune disorder which causes hair loss. Inflammatory reactions are involved in hair loss of the scalp and/or body. The involvement of chemokine receptors in the pathogenesis of AA is well defined among which, CXCL1 acts on neutrophils and CXCL9, CXCL10 and CXCL12 and serve as T lymphocytes recruiters. Objective: To study the serum levels o...
OBJECTIVE To investigate medical and environmental risk factors for central centrifugal cicatricial alopecia (CCCA), the most common type of scarring alopecia in African American women. DESIGN A population study involving a quantitative cross-sectional survey of risk factors for CCCA. Survey results are then correlated with a clinical evaluation for CCCA using a standardized, previously publi...
Central centrifugal cicatricial alopecia (CCCA) occurs primarily in African-American women and is the most common cause of scarring hair loss in this population. Since the mid 20th century, hair care practices of African-American women have been associated with CCCA, although there is developing evidence that the etiology of CCCA may be multifactorial. Clinically diagnosing CCCA may be challeng...
Pityriasis amiantacea is a rare cutaneous reaction pattern to various underlying inflammatory diseases of the scalp. The clinical findings are very characteristic but often under-recognized. This condition can lead to scarring alopecia, and can be refractory to conservative treatment. It is therefore important to recognize the condition so that appropriate treatment can be initiated promptly.
BACKGROUND Frontal fibrosing alopecia (FFA) is an acquired scarring alopecia currently considered a clinical variant of lichen planopilaris (LPP). Our purpose was to examine the clinicopathological features of FFA. In addition, we investigated the similarities and differences between FFA and LPP. METHODS Biopsies from the scalp lesions of eight patients with FFA and eight patients with LPP we...
The diagnosis of disorders of the hair and scalp can generally be made on clinical grounds, but clinical signs are not always diagnostic and in some cases more invasive techniques, such as a biopsy, may be necessary. This 2-part article is a detailed review of the histologic features of the main types of alopecia based on the traditional classification of these disorders into 2 major groups: sc...
BACKGROUND Central centrifugal cicatricial alopecia (CCCA) is the most common cause of scarring alopecia among women of African descent which affects the central scalp and spreads centrifugally but spares the lateral and posterior scalp. OBJECTIVES The objective of this study is to report on a new clinical variety of CCCA presenting with patchy alopecia involving the lateral and posterior sca...
From the Division of Dermatology, Department of Internal Medicine, Baylor University Medical Center, Dallas, Texas. Corresponding author: Jennifer Clay Cather, MD, 3600 Gaston Avenue, Suite 651, Dallas, Texas 75246. tent with a scarring (cicatricial) form of alopecia. Additionally, there were hypopigmented lesions on her arms (Figure 2) and targetoid plaquelike lesions on her legs (Figure 3). W...
VPA: valproic acid INTRODUCTION Valproic acid (VPA), a widely used antiepileptic drug and mood stabilizer, has myriad cutaneous side effects including transient alopecia, exanthems, and vasculitides. We report on a patient who, in the setting of VPA use, presented with nail nonadherence secondary to sterile matrix scarring and propose nail bed excisionwith sterile matrix grafting as a surgical ...
