Key result
Synovial sarcoma in rare sites including the heart requires careful histopathology and immunohistochemistry for diagnosis.
Why the study?
Synovial sarcoma typically occurs in the extremities around joints, but can arise in surprising rare locations requiring careful histopathological examination.
Case Report (n=7)
No
Synovial sarcoma should be considered in the differential diagnosis of mass lesions in young patients, even in rare locations like the heart, lungs, and kidney.
Supports inclusion in differentials for atypical cardiac, pulmonary, or renal masses; extends anatomic spectrum but remains hypothesis-generating.
Background: Synovial sarcoma is an infrequently diagnosed soft tissue sarcoma of the younger population with a male preponderance. Although the disease tends to home itself in the extremities particularly around the joints in the vast majority of cases, it can also occur in other surprising locations which warrant careful and meticulous histopathological examination accompanied by a judicious use of the immunohistochemical panel. Methods: Search of the pathology database was done to identify cases of synovial sarcomas in rare sites. Result: seven cases of synovial sarcoma were identified, three of which were at extremely uncommon sites rendering the diagnosis challenging and intriguing. Conclusion: Differential diagnosis of synovial sarcoma should always be kept in mind in a young patient with a mass lesion of short duration, not only at the extremities but also involving other rarer locations like the lungs, heart and kidney.

Ahmed et al. (2018) conducted a case report in Synovial Sarcoma (n=7). Histopathological and immunohistochemical evaluation was evaluated on Clinicopathological and immunohistochemical features of synovial sarcoma. Synovial sarcoma can occur at rare anatomical sites such as the lung, heart, and kidney, necessitating careful histopathological examination and judicious use of immunohistochemistry for accurate diagnosis.
