Abstract
Aggressive angiomyxoma and cellular angiofibroma are uncommon mesenchymal tumors. Imaging plays an important role in suggesting their diagnosis and in delineating the extent of the lesion. Additionally, histopathological examination provides the definite diagnosis. An understanding of their histological features and correlating that with the key imaging features on radiology helps in narrowing the differential diagnosis, and thereby aids in management and outcome. We herein present a case of both entities in patients presenting with history of a palpable peri-anal mass. We describe the radiological and histological features of aggressive angiomyxoma and cellular angiofibroma and highlight the similarities and differentiating factors between them.
