Unusual Synovial Tumors

Synovial Sarcoma of the Foot

“…In a certain number of cases, synovial sarcoma originates from the joints; in other cases, the origin is extra‐articular. All these findings suggest that synovial sarcoma originates not from the normal synovial cells, joints, bursae, and tendons, but rather from undifferentiated mesenchymal cells, with a potential to differentiate toward synovial structures 2,4,6–18,20–25 . Other authors have suggested that synovial sarcoma may develop as the result of metaplasia of normal synovial cells.…”

“…According to Ariel and Pack, 5 synovial sarcoma comprises 8% of all malignant tumors of the soft tissue. Often the tumor is located on the lower limbs, 1,4,6–19 but there have been occurrences of it on other parts of the body (e.g., abdominal wall, thorax, larynx, and pharynx). The tumor that we report here was located on the medial aspect of the patient's foot.…”

Synovial sarcoma of the soft palate in a child: A light and electron microscopic study

“…Since 1954, when Jernstrom described for the first time a synovial sarcoma in the soft tissue of the parapharyngeal region, synovial sarcomas in the cervical area were reported by the following authors: Martens, 1955;McCormack and Parker, 1956;Pricolo andCenci, 1957;Yenermen, 1958;Das andDebb, 1961; Harrison et al, 1961;Marsh et al, 1963;Cachin et al, 1966;Batsakis et al, 1967;Vande-Weghe and Kluyskens, 1968;Attie et al, 1970;Novatney and Fort, 1971; Krugman <t f a/., 1973; Fisher and Spiro, 1974;Jacobs and Weaver, 1974;Liebman et al, 1974;Minnigerode, 1974;Moussavi and Ghodsi, 1974;Gattiefa/., 1975;GoXovab et al, 1975;Mazet, 1975;Miller et al, 1975;Roth et al, 1975;Lockey, 1976;Panh et al, 1976;Chelloul and Labayle, 1977;Bertoni and Bacchini, 1978;Choux et al, 1978;Gapany-Gapanavicius et al, 1978;Junien-Lavillauroy et al, 1978;Massarelli et al, 1978;Mischler etal, 1978;Nunez-Alonso *tf a/., 1979;Setzen et al, 1979. A vaguely-defined, deep-seated and usually painless swelling is the chief presenting symptom reported in 23 cases of synovial sarcoma in the neck region (Roth et al, 1975). However, some other clinical signs (hoarseness, dysphagia, dyspnoea) may become evident, depending on the localization of the neoplasm.…”
