title: Potential value and disadvantages of fine needle aspiration cytology in diagnosis of ameloblastoma.
abstract: Ameloblastoma is a benign, slow growing but locally aggressive tumor that is clinically manifested as swelling in a jaws. Prone to relapse (30%) even 30 years after inadequate primary operation. The most important cytological features of this tumor are small bazaloid cells in clusters, and single spindle and stellate shaped cells. We report on a case of 79-year-old patient, who was hospitalized due to tumor formation in the buccal region. FNA was performed and liquid material that contained only fagocites was collected. The conclusion was--cyst, while biopsy finding--adenoma baseo-cellulare, pointed to the salivary gland tumor. Patient refused the proposed surgical treatment. Four years later, the patient was urgently hospitalized due heavy bleeding from the tumor in the same region. It affected the crest portion of the upper jaw and a section of hard palate, and was bleeding on palpation. In second FNA we found phagocytes and a few small clusters of basaloid cells with palisade arrangement at the edges. Because of uniform and benign cytomorphological features it was concluded that it was a cystic tumor. On biopsy pattern the diagnose of ameloblastoma was determinated. The patient underwent surgery, however due to postoperative complications he died. Preoperative diagnosis is usually set on the basis of clinical and often nonspecific radiological findings. As it is very important to get the correct diagnose before planning an adequate surgical procedure, we would like to point out the potential value and disadvantages of FNA cytology in the diagnosis of ameloblastoma.
