“…The location of the lesion, namely, the temporomandibular joint, is of particular interest, as the occurrence of pigmented villonodular synovitis in this region is extremely rare. 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).…”
