Idiopathic Auricular Calcinosis Cutis

Abstract

To the Editor: Calcinosis cutis (CC) is a rare disease characterized by abnormal accumulation of insoluble calcium phosphate crystals in skin and subcutaneous tissues. 1 It is classified in 4 types as etiologically dystrophic, metastatic, iatrogenic, and idiopathic. 2 It is important to determine the type of calcinosis for proper treatment management. Dystrophic type CC is most common. Idiopathic CC is characterized by normal serum calcium and phosphorus. Idiopathic CC, which is the rarest type, is characterized by normal serum calcium and phosphorus levels, its etiology is not clear and is diagnosed by exclusion of other forms of CC. It is generally observed during childhood and adolescence. 3,4 Here, a case with idiopathic calcinosis cutis in the left ear helix is discussed and presented with the literature.

Endocrine Petrified Ear: Associated Endocrine Conditions in Auricular Calcification/Ossification (A Sample-Focused Analysis)

“…Local inflammation (that stands as a contributor/trigger to calcium deposits) may be found at pathological report, typically in dystrophic rather than metastatic cases. Calcification in petrified ears should be distinguished from isolated nodules found in calcinosis cutis, which is more common in pediatric populations [ 75 , 76 , 77 ]. Some authors suggested that calcification may turn into ossification amid the local action of different triggers such as trauma or frostbite [ 4 ]; thus poly-factorial etiology may be present.…”
