Thirty cases of the Bjornstad syndrome (sensorineural deafness and pili torti) have been reported between 1965, when it was first described, and 1999. Both autosomal dominant and recessive inheritance patterns appear in the literature. We describe a family in which 3 members have the combination of pili torti and varying degrees of hearing loss inherited in an apparently autosomal dominant fashion. Hairs from the father and son of this family showed the classic features of pili torti under scanning electron microscopy.

Alopecia patterns and trichoscopic findings in patients with autosomal recessive congenital ichthyosis.
Int J Womens Dermatol
October 2024
Dermatology Department, Habib Thameur Hospital, Tunis, Tunisia.
Article Synopsis
- Autosomal recessive congenital ichthyosis (ARCI) is a rare skin condition primarily characterized by skin scaling and hair abnormalities, which are often overlooked regarding their impact on patients' quality of life.
- This study involved clinical and trichoscopic examinations of 30 ARCI patients over three years, revealing that alopecia affects a significant number, with various patterns of hair loss documented among participants.
- Notable trichoscopic findings included scaling and different hair types that correlate with the severity of ARCI, suggesting that hair health is a crucial component of this condition often underestimated in prior research.
Trichoscopic findings in neonatal alopecia in oro-facial-digital syndrome type 1.
Pediatr Dermatol
November 2024
Dermatology Department, Hospital Sant Joan de Déu, Universitat de Barcelona, Barcelona, Spain.
Article Synopsis
- - Oral-facial-digital syndrome type 1 (OFD1) is an X-linked dominant disorder caused by mutations in the OFD1 gene, resulting in various facial, oral, and digital abnormalities.
- - Skin symptoms occur in about 20%-30% of affected individuals and include evanescent milia (small cysts) and patchy hair loss (alopecia), which can mimic other conditions like tinea capitis.
- - Diagnosis can be confirmed through genetic testing, especially when clinicians suspect OFD1 due to specific trichoscopic findings, lack of response to antifungal treatments, and presence of midline anomalies.
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.
