Cartilaginous metaplasia is a rare but well-documented phenomenon occurring in the wall of odontogenic keratocyst. The mural cartilage not associated with odontogenic keratocyst has been reported only once in a maxillary teratoid cyst of congenital origin to our knowledge. A case presented is a 38-year-old man with intraosseous keratinizing epidermoid cyst in the mandible, the wall of which contained a nodule of mature hyaline cartilage. The present lesion likely represents a previously undescribed, histologic hybrid consisting of orthokeratinized odontogenic cyst and cartilaginous heterotopia.
软骨化生是一种罕见但有充分文献记载的现象，发生于牙源性角化囊肿壁。据我们所知，与牙源性角化囊肿无关的壁内软骨仅在一例先天性上颌畸胎样囊肿中被报道过一次。本文报道的病例是一名38岁男性，下颌骨内有骨内角质化表皮样囊肿，其囊肿壁包含一个成熟透明软骨结节。目前的病变可能代表一种先前未被描述的组织学混合体，由正角化牙源性囊肿和软骨异位组成。
