Terminal osseous dysplasia with pigmentary defects (TODPD) is an extremely rare X‐linked dominant syndrome characterized by pigmentary skin defects, cutaneous digital fibromas and skeletal anomalies. Recent studies have identified that TODPD is caused by a unique variant, c.5217G>A (p.Val1724_Thr1739del), in the FLNA gene, which could in turn lead to the elastic fiber abnormality in TODPD. We herein present a rare case of TODPD in a Chinese girl due to an FLNA c.5217G>A heterozygous mutation, but the skin lesion biopsy showed that the elastic fibers were within normal limits in the dermis. A published work review of TODPD with the FLNA mutation from various origins is also included in this paper. To the best of our knowledge, this is the first report on TODPD with the FLNA mutation in China.
