Pigmented Villonodular Synovitis of the Temporomandibular Joint

Extra-articular pigmented villonodular synovitis of the temporomandibular joint

“…Moreover, many of these reported lesions showed extensive local infiltration into surrounding tissue. In fact, including our present patient, the lesions extended into the temporal bone and even the middle cranial fossa in seven instances (Dinerman and Myers, 1977;Geiger and Pesch, 1980;Eisig et al, 1992;Ohira, 1994;Shapiro et al, 1996;Tanaka et al, 1997). This local aggressive infiltrative behaviour is also more consistent with that of the extra-articular rather than localized variant of pigmented villonodular synovitis.…”

“…The first two cases were reported by Lapayowker et al in 1973. Since then, additional cases have been described, mostly in the form of single case reports (Barnard, 1975;Miyamoto et al, 1977;Raibley, 1977;Makek and Drommer, 1978;Takagi and Ishikawa, 1981;Rickert and Shapiro, 1982;Gallia et al, 1982;Curtin et al, 1983;O'Sullivan et al, 1984;Dawiskiba et al, 1989), and reviewed by Eisig et al (1992). A number of additional case reports were also published recently (Syed et al, 1993;Franchi et al, 1994;Ohira, 1994;Shapiro et al, 1996;Youssef et al, 1996;Yu et al, 1997;Tanaka et al, 1997). Including the present case, a total of about 22 cases of pigmented villonodular synovitis of the temporomandibular joint are thus found in the literature.…”

Tenosynovial, Diffuse Type Giant Cell Tumor of the Temporomandibular Joint, Diagnosis and Management of a Rare Tumor

“…First description of involvement of the TMJ was by Lapayowker et al in 1973, and since then 27 cases have been reported in the English literature [ 13 , 14 ]. FNA has been described as a possible method of diagnosis by Tanaka et al; however, a successful diagnosis in our case with FNA was not possible [ 15 ].…”

Fine needle aspiration of pigmented villonodular synovitis of the temporomandibular joint

“…The cytologic features are similar to those of lesions occurring in other, more common anatomic sites. As mentioned in the case reports,3, 9–11 FNA smears generally show a cellular specimen comprised of many loosely cohesive clusters of and single mononuclear and multinucleated giant cells. The mononuclear cells are round to oval to spindled, and contain small, often paracentrally‐located nuclei.…”

“…To our knowledge, there have only been four case reports of PVNS of the TMJ in the English‐language cytology literature 3, 9–11. The cytologic features are similar to those of lesions occurring in other, more common anatomic sites.…”
