   Medical History Top


A 2-year-old boy presented with his parents to our outpatient department because his hair had gradually turned rough and dry after his first birthday. The boy had short, straight, dark-blond, “straw-like,” and tousled hair. The mother had not noticed brittleness. He had a ring of lighter colored hair around his vertex [Figure 1]a. He did not show any other anomalies of the teeth, hair, nails, or sweat glands. He was a single child and had no relevant medical record except for a mild plagiocephalus of the right scull due to the chosen lying position that self-resolved at the age of 3 months. Furthermore, he had suffered from a streptococcal sepsis with reactive arthritis of the hips, elbows, and knees at the age of 6 months.

   Diagnostic Findings Top


We performed a light microscopy evaluation of the patient's hair shaft and of a healthy person's hair shaft [Figure 1]b and c]. The hair of the healthy person showed a normal oval contour, while the patient's hair showed a triangular-shaped profile and longitudinal grooves along the shaft [Figure 1]b.


   What Is Your Diagnosis? Top


Diagnosis

We diagnosed pili trianguli et canaliculi (syndrome of uncombable hair or “spun glass hair”); a hair shaft anomaly that is caused by dysfunctional skin papillae that lead to an abnormal keratinization in the root sheath of the hair. The syndrome occurs sporadic and less frequently, with autosomal-dominant or autosomal-recessive inheritance. It can rarely be associated with ectodermal dysplasia.[1] The hair turns rough and dry at the age between 3 and 12 months. In contrast to other hair shaft disorders, the amount of hair does not diminish as there is no hair loss or brittleness.[2]

The syndrome does not require treatment as it often resolves in late childhood.[3]
