Multiple Defects of the Hair Shaft in Netherton's Disease

Two patients with ichthyosis linearis circumflexa, a skin condition associated with a syndrome similar to Netherton's disease, exhibited multiple hair shaft defects. These defects included variations in hair thickness, trichorrhexis nodosa, bamboo hairs, and various cup and ball deformities. The study also described the histological features of the hair follicles and explored the potential significance of an associated aminoaciduria.
