Chondromyxoid Fibroma of the Mandible: A Diagnostic Pitfall on Aspiration Cytology of Parotid

Diagnostic Difficulties in the Interpretation of Fine Needle Aspirate Samples in Salivary Lesions

“…6,10,14,15,30 Our 15 years of experience shows that FNA of the salivary gland is a valuable tool in workup of patients with salivary gland lesions. The various cases cited in this study are possible sources of erroneous diagnosis.…”

“…12 A rapidly growing chondromyxoid fibroma of the mandible was diagnosed as carcinoma ex pleomorphic adenoma based on the giant and atypical mononuclear cells ( Figure 11). 15 A sebaceous cyst of skin with many foamy acinic-like cells ( Figure 12) in the parotid area was diagnosed as a clear cell neoplasm. An aspirate of pilomatrixoma yielded clusters of basaloid cells with peripheral palisading ( Figure 13A), many small round eosinophilic centers mimicking keratin pearls, atypical keratinized cells and foreign body giant cells in a dirty background ( Figure 13B).…”

“…15 A submandibular soft tissue mass on aspiration was diagnosed as basal cell adenoma ( Figure 26A), but excisional biopsy and later radiologic workup proved this to be a mandibular ameloblastoma with soft tissue extension ( Figure 26B). …”

An Abnormal Bone Lesion of the Scapula in a Collegiate Basketball Player: A Case Report

“…[11][12][13] The tibia is the most affected long bone, followed by the femur. 7,13 A CMF tumor in the upper extremity is rare, but it has been described in the scapula, [14][15][16] rib, 17 sternum, 18 pelvis, 19 mandible, 20 and occiput. 21 A CMF of the scapula occurs in only 0.8% to 3% of all CMF cases.…”

Fine Needle Aspiration of Salivary Gland Lesions with Multinucleated Giant Cells

“…After an imaging study and excisional biopsy, the diagnosis of CF was made. 11 There was a case of osteosarcoma of the mandible, with invasion of the parotid, that contained many osteoclastic-type MNGCs (case 21).…”
