ABSTRACT
A 2-year- and 2-month-old girl developed recurrent eczema-like rashes 7 days after birth, followed by the occurrence of poikiloderma and hair loss. Cholestasis occurred at the age of 1 month and 10 days, which was improved but serum transaminase levels were elevated after 4 months. The patient usually presented with slight sweating, heat intolerance, and delayed gross motor development. Skin examination showed generalized mottled hypo- and hyper-pigmented patches, especially in the exposed areas, and sparse hair and eyebrows. Her parents had no similar clinical manifestations. Whole-exome sequencing showed a mutation c.1883G>A (p.Ser628Asn) in the FAM111B gene in the child, which was not found in her parents. According to the typical skin lesions, abnormal liver function and genetic testing results, this patient was diagnosed with hereditary fibrosing poikiloderma with tendon contracture, myopathy, and pulmonary fibrosis, and the mutation c.1883G>A in the FAM111B gene may be the cause of the patient′s clinical manifestations. The patient received hepatoprotective therapy, sun screen intervention, rehabilitation training, etc. After 10-month follow-up, the patient still presented with skin lesions and elevated transaminases, but without other discomforts.
