We report a twenty-seven-year-old man with the absence of hair on the scalp and eyebrows, which began shortly after his birth. One of his brothers had this problem too. Considering clinical signs and skin biopsy report of the patient, a diagnosis of congenital atrichia was made. The latest findings on the genetic of this disease will be reviewed.

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.

BACKGROUND Alopecia areata incognita is a variety of alopecia areata characterized by acute diffuse shedding of telogen hairs without typical patches. OBJECTIVE We sought to report the clinical, pathological, and dermoscopic features of alopecia areata incognita. METHODS Seventy patients with alopecia areata incognita were evaluated clinically and with videodermoscopy during the period of 2...

Background and Objective: Non-scarring alopecia is a challenge in the diagnosis and treatment, rarely studied in Asian countries. The current study aimed at evaluating histopathological features including hair count of different subtypes of non-scarring alopecia in Iranian patients.Methods: The current study was conducted on 114 cases diagnosed with...

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...

BACKGROUND Alopecia areata is marked by autoimmune assault on the hair follicle resulting in hair loss. T helper 17 cell subset has important roles in protecting the host against extracellular pathogens, however, also promotes inflammatory pathology in autoimmune disease, and it expresses both interleukin (IL)-17A and IL-17F, which can signal via the IL-17 receptor A. OBJECTIVE To investigate...

INTRODUCTION: Vitiligo is an acquired autoimmune skin disease clinically manifested by foci of depigmentation due to the death epidermal melanocytes. Although vitiligo most often runs in isolation, being limited a pathological process skin, this can lead development number comorbid disorders. Alopecia areata also disorder appendages, one common disorders vitiligo, manifesting along with main di...

In adult skin, hair follicles cyclically self-renew in a manner that recapitulates embryonic hair follicle morphogenesis. The most common pathology of hair in adults is alopecia, which is hair loss to different extent. There are a number of murine models of alopecia including spontaneous mutations. In the present study, we worked with double homozygous we/we wal/wal mice which demonstrate sympt...
