Presentation
The patient, a 20-year old girl, had been presenting with the hair abnormality since birth. [unboundmedicine.com]
We present a 13-year-old girl who had alopecia areata and coincidentally was found to have pili annulati. Her mother also had pili annulati which had become more noticeable as her hair had become paler with age. [scienceopen.com]
Conclusions The present results suggest that the microcanaliculi of the hair surface, easily found with scanning electron microscopy, may be secondary not only to the cavities seen in the sections but also to the disorder of proteins that form this region [anaisdedermatologia.org.br]
Case Presentation A 12-year-old boy presented with a band of red hair over the interparietal region that was present since birth and had become more obvious over the years ( Figure 1A ). The rest of his scalp hair, eyebrows and eyelashes were brown. [dpcj.org]
Most hairs present with minor surface abnormalities associated with nodes. However, more severe hair damage and breakage can occur in a minority of cases [7]. [escholarship.org]
Entire Body System
- Asymptomatic
Symptoms Asymptomatic Light bands on hair shaft Dark bands on hair shaft Fragile hair Causes Alopecia areata Alopecia areata is usually marked by well-circumscribed patches of nonscarring hair loss on the scalp without skin changes. [checkorphan.org]
Careful clinical examination is necessary to establish the diagnosis of pili annulati as it is an asymptomatic condition. [ncbi.nlm.nih.gov]
Musculoskeletal
- Fracture
Hair shafts and cryo-fractured surfaces were examined by scanning electron microscopy. RESULTS. 1. Light microscopy. Lesions were found in every hair examined. [unboundmedicine.com]
(D) Mechanical trauma on the swollen node fractured the hair ends, as shown by the frayed macrofibers. [synapse.koreamed.org]
In addition, white nodular swelling was evident that resembled the ends of two brushes aligned in opposition, and the end of the fractured hairs was a paint-brush appearance (Fig. 2C, D). [docksci.com]
Oblique Fractures- Tapered Fracture Fractures of the hair that cause a pencil point appearance are due to inhibition of nucleic acid and protein synthesis and therefore mitosis during anagen. [hairtx.com]

- Alopecia
An association with alopecia areata has been reported. We present a 13-year-old girl who had alopecia areata and coincidentally was found to have pili annulati. [scienceopen.com]
