title: Hutchinson-Gilford progeria syndrome with severe skin calcinosis.
abstract: We describe a case of Hutchinson-Gilford progeria syndrome (HGPS) with long-term follow-up. A 1-month-old girl with marked sclerodermatous skin changes developed various symptoms of HGPS during follow-up. These included sclerotic skin, pigmentation, skin atrophy with translucent veins, wispy hair and alopecia, nail dystrophy and decreased sweating. Marked skin calcinosis was observed over almost the entire body, a symptom that has apparently been ignored in the literature. At 16 years old, the girl underwent surgery for a skull fracture and subdural haematoma, which was followed by chronic ulceration. Wet dressing with insulin-like growth factor was used with considerable effect. Mutation of the lamin A/C (LMNA) gene mutation, which encodes nuclear lamin A and C, has been reported to be the cause of HGPS. Our case showed the mutation G608G (GGC-->GGT), which resulted in a cryptic splice site and consequently in a truncated lamin A/C protein.
