Real anal leiomyoma: a case report.
ABSTRACT Leiomyoma of the rectum and anal canal is an unusual benign mesenchymal neoplasm that originates from smooth muscle cells. We describe the clinical presentation, MRI findings, and surgical treatment of a rare case of perianal leiomyoma confirmed by immunohistochemistry. We also report a review of the world's literature on the subject.

ABSTRACT: Background: Alveolar soft part sarcoma (ASPS) is a rare diagnosis in the perianal region. Methods: we describe the clinical presentation, pathological findings and differential diagnosis of a rare case of perianal ASPS. We also describe the importance of the preoperative embolization of the hypervascularised masses to prevent surgical bleeding. Conclusions: clinical and pathological findings are essential for the diagnosis, specifically by immunochemistry and molecular techniques, as the demonstration of ASPL/TFE3 fusion transcript became indispensable in some cases. Preoperative embolization of the hypervascularised masses may prevent uncontrollable surgical bleeding.Central European Journal of Medicine 04/2014; 9(2).
