Hair Shaft Abnormalities as a Dermoscopic Feature of Mycosis Fungoides: Pilot Results.
Dermatol Ther (Heidelb)
August 2024
Department of Dermatology, Medical University of Warsaw, Koszykowa 82a Street, 02-008, Warsaw, Poland.
Introduction: Diagnosis of persistent erythematous, scaly patches, or plaques can be complex since psoriasis (Ps), eczematous dermatitis (ED), and mycosis fungoides (MF) can be considered. Dermoscopy, which is a noninvasive diagnostic tool, is commonly used to examine blood vessels, scales, and background color; however, research on hair shaft evaluation in inflammatory dermatoses remains scarce. The aim of the study was dermoscopic evaluation of hair shafts in skin lesions localized on the non-scalp skin areas in patients diagnosed with MF, Ps, and ED.

Article Synopsis
- Trichorrhexis nodosa (TN) is a hair shaft defect caused by excessive physical or chemical damage, making it challenging to diagnose without a microscope.
- Trichoscopy, a newer technique, shows promise as an effective outpatient method for diagnosing hair shaft defects, as demonstrated in a case of a young girl with localized TN due to trichotillomania.
- The report highlights the distinct appearance of TN and the benefits of using trichoscopy for quick and accurate diagnosis, along with a review of related literature.
Article Synopsis
- - A child has been observed with red, scaly skin lesions on their arms and legs for the past 2 months.
- - Histological examinations indicated the possibility of ichthyosiform disease, which relates to skin conditions characterized by dry, scaly skin.
- - Genetic testing revealed mutations in the SPINK5 and FLG2 genes, confirming a diagnosis of Netherton syndrome, which is associated with severe allergic reactions and skin issues.

Trichothiodystrophy type 4 is a rare autosomal recessive and ectodermal disorder, characterized by dry, brittle, sparse and sulfur-deficient hair and other features like intellectual disability, ichthyotic skin and short stature, caused by a homozygous mutation in MPLKIP gene. Glutaric aciduria type 3 is caused by a homozygous mutation in SUGCT gene with no distinctive phenotype. Both genes are localized on chromosome 7 (7p14).
