Reliability of Histopathology for the Early Recognition of Fibrosis in Traction Alopecia: Correlation with Clinical Severity.

Traction alopecia (TA) is hair loss caused by prolonged pulling or repetitive tension on scalp hair; it belongs to the biphasic group of primary alopecia. It is non-scarring, typically with preservation of follicular stem cells and the potential for regrowth of early lesions especially if traction hairstyles are stopped. However, the alopecia may become permanent (scarring) and fail to respond to treatment if the traction is excessive and prolonged.

Arteriovenous malformation after punch biopsy clinically mimicking a basal cell carcinoma: Case report and review of literature.

Arteriovenous malformations (AVM's) of the skin can be acquired post blunt or penetrating trauma. They may clinically mimic basal cell carcinomas and other lesions with overlying telangiectasia. Specific clinical, dermoscopic, and histological clues differentiate these conditions.

Actinic comedonal plaque in skin of color: A case report.

Actinic comedonal plaque is a variant of Favre-Racouchot syndrome which is a complication of solar degeneration of the skin. It is common in skin types 1-4 and unknown to rare in skin of color. This case report should create an awareness of this disease so not to be missed.

Angioedema, an unusual reaction to hair dye.

Angioedema is a type-1 hypersensitivity reaction that can be life threatening. It affects the skin airways and the gastrointestinal tract. Henna is a green powder used to dye skin and nails.

Emerging Diagnostic and Therapeutic Potentials of Human Hair Proteomics.

The use of noninvasive human substrates to interrogate pathophysiological conditions has become essential in the post- Human Genome Project era. Due to its high turnover rate, and its long term capability to incorporate exogenous and endogenous substances from the circulation, hair testing is emerging as a key player in monitoring long term drug compliance, chronic alcohol abuse, forensic toxicology, and biomarker discovery, among other things. Novel high-throughput 'omics based approaches like proteomics have been underutilized globally in comprehending human hair morphology and its evolving use as a diagnostic testing substrate in the era of precision medicine.
