“…Although the diagnostic nosologic problem remains, the term AAD is applied to a rare plexiform ameloblastoma with microscopic features of AOT including duct-like structures and dentinoid deposition [10]. As shown in the present and previous cases [15], the final diagnosis of AAD was made only in retrospect, after multiple recurrences. It is imperative to understand that AAD is actually an ameloblastoma with propensity for infiltration and recurrence.…”

Considerable variation in the clinicopathologic presentation of epithelial odontogenic tumors can sometimes be confusing and increase the chance of misdiagnosis. Seven diagnostically challenging jawbone lesions are described. There were 2 cases of mistaken identity in our ameloblastoma file. One unicystic type, initially diagnosed and treated as a lateral periodontal cyst, showed destructive recurrence 6 years postoperatively. The other globulomaxillary lesion was managed under the erroneous diagnosis of adenomatoid odontogenic tumor and recurred 4 times over an 11-year period. This tumor was found in retrospect to be consistent with an adenoid ameloblastoma with dentinoid. The diagnosis of cystic squamous odontogenic tumor (SOT) occurring as a radicular lesion of an impacted lower third molar was one of exclusion. Of two unsuspected keratocystic odontogenic tumors, one depicted deceptive features of pericoronitis, while the other case has long been in our files with the diagnosis of globulomaxillary SOT. Two cases of primary intraosseous squamous cell carcinoma appeared benign clinically and exhibited unexpected findings; an impacted third molar began to erupt in association with the growth of carcinoma and another periradicular carcinoma showed dentinoid formation. Cases selectively reviewed in this article present challenging problems which require clinical and radiographic correlation to avoid potential diagnostic pitfalls.

“…Of these, the cases reported by Slabbert et al ,[1] Evans et al ,[7] Orlowski et al ,[8] Tajima et al ,[9] Matsumoto et al [10] and in the present report, the tumor was diagnosed as ameloblastoma, while in six other reports the tumor was considered to be AOT. Teakeda et al reported bone formation in their report[11] while the other cases have mentioned the hard tissue as dentin or dentinoid.…”

Ameloblastomas seldom cause diagnostic difficulties due to classic histopathological presentations. Adenoid ameloblastoma is a rare variant in this category which can cause problem in diagnosis due to the presence of areas resembling adenomatoid odontogenic tumor (AOT) and occurrence of varying degrees of dentinoid formation. In this article, we report a case of adenoid ameloblastoma with dentinoid, which was diagnosed accurately after the third recurrence. To the best of our knowledge, so far, only 13 cases have been reported of tumors that histologically show features of amelobalstoma and AOT with hard tissue formation. The recurrences were due to under diagnosis of the lesion followed by a conservative treatment.

“…The histopathological features of this composite odontogenic tumour varied in various cases reported in the literature, with regard to hard tissue formation. The cases reported by Ghasemi-Moridani and Yazdi,4 Evans et al ,5 Matsumoto et al ,6 Sonone et al ,7 Orlowski et al ,10 Tajima et al , Takeda,11 Dunlap and Fritzlen,12 and Kiran et al show histopathological features of AOT and ameloblastoma, most commonly plexiform. The cases reported by Allen et al and Slabbert et al 2 show features only of ameloblastoma.…”

“…Follow-up in most of the reported cases showed no recurrence to a maximum of 8 years. Evans et al 5 described a recurrent lesion that had initially been diagnosed as AOT. Later, after the third recurrence and reviewing of all histologic findings, they named it adenoid ameloblastoma with dentinoid.…”

Mixed odontogenic tumour with dentinoid and ghost cells

Ameloblastomas do not generally show evidence of induction, however, rare cases associated with odontome have been reported and are referred to as odontoameloblastomas. We report an unusual case of an ameloblastoma with features of an adenomatoid odontogenic tumour, showing evidence of induction of dentinoid by tumour cells--but without concomitant formation of enamel--and with features of ghost cells. The lesion occurred on the left side of the maxilla in a 31-year-old woman.
