“…In effect, the latter were significantly older at the time of diagnosis than the patients with benign lesions (48 years and 9 months ± 19 years and 1 month versus 40 years and 6 months ± 15 years and 1 month; t=3.65, p<0.002). The recorded mean age is consistent with the 51 years reported by Bavitz et al (12) at the time of diagnosis of malignant TMJ tumors. On excluding pseudotumors from the analysis, the difference in age between the benign and malignant tumors was found to increase, since the mean age of the patients with true benign tumors was 31 years and 4 months ± 17 years and 6 months (t=4.2, p<0.000).…”

“…Occlusion alterations, one of the signs most suggestive of joint tumors together with the presence of swelling, were reported in 20.5% of the patients – this proportion being slightly greater than the 10% reported by Bavitz et al for malignant tumors (12). In one-third of the cases there were no occlusion disorders, and in almost one-half of the cases studied (44%) no mention was made of whether such alterations were recorded or not.…”

“…Two findings appear particularly relevant: in almost one-half of the cases (46.5%) no mention was made of whether there were P-Rx alterations or not, and in 40 cases (14.0%) such alterations were reported to be absent – this being explained by the fact that a calcium loss of 50% or more is required in order for the lesion to be radiographically visible (12)-. Radiotransparencies were significantly more frequent in the tumors (77.8%) than in the pseudotumors (22.0%) (χ2=40.9; p=0.000).…”

Objective: To review the pseudotumors and tumors of the temporomandibular joint (TMJ) published in journals included in Journal Citation Reports (JCR), and to evaluate whether there are clinical and radiological signs capable of differentiating between pseudotumors and tumors and between malignant and benign tumors. Material and Methods: A systematic Medline search was made of clinical cases of tumors and pseudotumors of the TMJ covering a 20-year period and published in journals included in JCR. Only cases with histological confirmation were included. A description is provided of the general characteristics of TMJ tumors, with comparison of the clinical, diagnostic, therapeutic and evolutive variables referred to pseudotumors, benign tumors and malignant tumors. Results: We identified 285 TMJ tumors published in 181 articles of 15 journals. The most frequent lesions were pseudotumors (synovial chondromatosis, pigmented villonodular synovitis, eosinophilic granuloma and osteochondroma). The mean age was 42 years and one month ± 16 years and two months. Tumors were more common in females. The mean time from symptoms onset to consultation was 30 months and 8 days ± 41 months and 9 days, and almost 19.6% of the cases initially had been diagnosed and treated as TMJ dysfunction. The most frequent clinical manifestations were pain, swelling and the limitation of joint movements. The most common radiological findings in the case of benign and malignant lesions were radiopacities and radiotransparencies, respectively. No panoramic X-ray alterations were observed in 14.6% of the benign tumors and in 7.7% of the malignant lesions. Surgery was the usual form of treatment. Sequelae were recorded in 18.2% of the cases, with tumor relapse in 9.1%. The four-year survival rate in the case of malignant tumors was 72.2%. Key words:Tumor, temporomandibular joint, metaplasia, pseudotumor, condyle.
