Lipoblastoma-like tumor is a very rare mesenchymal tumor believed to be restricted to female patients and only recently reported in the spermatic cord of a male patient. We describe herein an additional case of lipoblastoma-like tumor occurring in the spermatic cord, describing its histopathological, immunohistochemical, and molecular features.... Read more

Perivascular epithelioid cell tumors (PEComas) are rare mesenchymal neoplasms with unpredictable behavior. They are characterized by epithelioid cells, which stain with melanocytic markers, associated with spindle cells reactive for smooth muscle markers. PEComas may be sporadic or associated with the tuberous sclerosis complex, with mutations affecting mostly tuberous sclerosis complex... Read more
