Spermatocytic tumor, formerly known as spermatocytic seminoma, is an uncommon testicular neoplasm which is a distinct clinicopathologic entity from classic seminoma. These tumors are not associated with germ cell neoplasia in situ, other germ cell tumors, or isochromosome 12p. Although typically, these tumors have an excellent prognosis occasional cases are associated with sarcoma and have a very poor prognosis. We present a case of spermatocytic tumor with sarcoma showing a chondrosarcomatous component, discuss the pathologic findings and differential diagnosis and provide follow-up information.

Primary renal synovial sarcoma is a rare malignancy that may present similarly to other renal neoplasms. The diagnosis of synovial sarcoma is performed through the identification of a SYT-SSX gene fusion. Here, we present a case of a primary renal synovial sarcoma in a patient who presented with renal mass initially thought to be renal cell carcinoma until further pathological characterization. After undergoing radical open nephrectomy, the patient developed pulmonary and psoas metastases and was treated with systemic therapy. [ABSTRACT FROM AUTHOR]
