Pathology of Pseudocyst of Auricular Cartilage - (Idiopathic Cystic Chondromalacia)

Dr Sampurna Roy MD




"Pseudocyst of the auricle" is defined as intracartilaginous cavity lacking epithelial lining. According to previous reports "pseudocysts" are supposed to occur due to chondromalacia within the cartilage.

Idiopathic cystic chondromalacia can occur in both sexes, in all races, and at any age.      

This rare condition is characterized by asymptomatic cystic swelling of the auricle resulting from accumulation of yellow viscous fluid.

Lesions for which this condition has been mistaken include relapsing polychondritis, Chondrodermatitis Nodularis Chronica Helicis , traumatic perichondritis, hemangioma, chondroma, angiosarcoma, and chondrosarcoma.
