Nail hypoplasia

Hypoplasia (from Ancient Greek ὑπo- hypo-, "under" + πλάσις plasis, "formation"; adjective form hypoplastic) is underdevelopment or incomplete development of a tissue or organ. Although the term is not always used precisely, it properly refers to an inadequate or below-normal number of cells. [Source: Wikipedia ]
