A rare medical condition characterized by the absence or underdevelopment of phalanges (finger or toe bones), often associated with genetic disorders.
From 'ana-' (absence) + 'phalanx' (finger/toe bone) + '-iasis' (disease condition). This is a highly specialized medical term combining Greek roots to describe a skeletal developmental disorder.
This word is so obscure that even many doctors would need to look it up—it's the kind of ultra-specific medical diagnosis that exists in rare disease databases but rarely appears in clinical practice. It illustrates how medical terminology can describe almost any possible developmental variation.
