Marsupialization as a possible diagnostic aid in cystic ameloblastoma. Case report.
Two cases of cystic ameloblastoma are described in which the diagnosis was established after marsupialization. Although the clinical and radiographic findings strongly suggested the diagnosis of ameloblastoma, the initial incisional biopsy specimens consisted of cystic walls lined with squamous epithelium which showed in both cases no evidence of ameloblastic proliferation. Marsupialization could be a diagnostic aid in these cases since relief of intracystic pressure may trigger regeneration of a solid mass of tumour in a monocystic ameloblastoma with cells possessing potentiality for spontaneous proliferation.
