Ameloblastoma is the most common odontogenic tumor which presents with a variety of histopathological patterns. Among all, papilliferous keratoameloblastoma (PKA) is a very rare type which is characterized by multiple epithelial cysts of varying size, which are lined by non-keratinized papilliferous epithelium which is filled with necrotic desquamated epithelial cells. In this study, we reported PKA with characteristic ameloblastic features in a 65-year-old male patient who presented with a swelling in the right mandibular body region. This is the seventh case of PKA to be reported in the English literature till date. Present case showed multicystic areas in incision biopsy which lead to misdiagnosis as calcifying odontogenic cyst with adenomatoid odontogenic tumor, but in excision biopsy which turned out to be papilliferous keratoameloblastoma, further in this paper we had discussed all the areas which lead to misdiagnosis of calcifying odontogenic cyst with adenomatoid odontogenic tumor. In outlook, more cases will put an insight to the behavioral aspects of this rare histological type of ameloblastoma.
