macrodactyly
Pronunciation: mak-roh-DAK-tih-lee
Congenital overgrowth of one or more digits resulting in disproportionately large fingers or toes.
Full Definition
A rare congenital anomaly characterized by localized gigantism affecting one or more digits. The condition involves overgrowth of all tissues including bone, soft tissue, and nerves. Two types exist: static (growth proportional to normal growth) and progressive (accelerated growth rate). Treatment may include staged debulking procedures, epiphysiodesis, or amputation in severe cases.
Usage
Usage note: Distinguish between static and progressive types; specify which digits are affected.
In Context
- "Progressive macrodactyly of the index finger required multiple debulking procedures and early epiphysiodesis." — Pediatric surgery case
- "Static macrodactyly was managed conservatively with excellent functional outcomes." — Follow-up assessment
