A 41/2-month-old infant, the product of a normal pregnancy, labor, and delivery had a folded right ear at birth. At the apex of the fold there was a crusted erythematous nodule. A biopsy specimen of this nodule at age 41/2 months showed collections of calcium surrounded by epithelioid histiocytes in the dermis. This case calls attention to the rare condition of congenital nodular calcification of the skin. In the case of this 41/2-month-old infant, trauma may well have been the precipitating cause. This is the first of congenital nodular calcification involving the ear.
一名4个半月大的婴儿，孕期、分娩过程均正常，出生时右耳折叠。在褶皱顶端有一个结痂的红斑结节。该结节在4个半月大时的活检标本显示真皮中有钙沉积物，周围是上皮样组织细胞。此病例提醒人们注意皮肤先天性结节性钙化这种罕见病症。对于这名4个半月大的婴儿来说，创伤很可能是诱发原因。这是首例累及耳部的先天性结节性钙化病例。
