Cytological diagnosis of acanthomatous ameloblastoma

Fine-needle aspiration cytology as a useful diagnostic adjunct in the management of ameloblastoma: A report of four cases

“…also reported a case of acanthomatous ameloblastoma diagnosed on the basis of similar cytological features. [ 4 ] Similarly, granular cell ameloblastoma was also diagnosed on the basis of cytological findings by Deshpande et al . [ 5 ] Granular ameloblastoma being most aggressive variant needs maximum resection and fortunately can be diagnosed through cytological studies.…”

Recurrent ameloblastoma of the mandible: Surgical seeding or metastasis of malignant ameloblastoma?

“…Ameloblastoma is an uncommon disease that represents 1% of all cysts and tumors diagnosed in the jaws [1,2]. These benign slow-growing aggressive neoplasms show a distressing tendency to exhibit locally aggressive behavior and local recurrence in 50% to 72% of cases [3,4].…”

Acanthomatous ameloblastoma masquerading as a squamous cell carcinoma

“…In a recent study by Masloub et al ., 4 the authors observed that high expression of CD10 and osteopontin in ameloblastomas may indicate locally invasive behaviour and a high risk of recurrence. The acanthomatous variant of ameloblastoma is diagnosed on FNAC by the presence of basaloid cells, with or without peripheral palisading, stellate reticulum cells and squamous cells in the appropriate clinical and radiological setting 2,5,6 . The main differential diagnoses on smears showing squamous cells include SCC, acanthomatous ameloblastoma, Warthin’s tumour, mucoepidermoid carcinoma, metaplastic adenocarcinoma, epidermal inclusion cyst, branchial cleft cysts and odontogenic keratocysts 2,5,6 …”

WarthinÕs tumour is diagnosed by the presence of oncocytic cells and lymphoid cells, whereas mucoepidermoid carcinoma shows some evidence of intra-or extracellular mucin, even in squamous cell-predominant cases.…”
