Highly aggressive Buschke-löwenstein tumor of the perineal region with fatal outcome.

Indian Journal of Dermatology, Venereology, and Leprology | September-October 2012 | Vol 78 | Issue 5 648 shows fibroblastic proliferation with variable vascularity and lack of inflammatory infiltrate, as seen in this patient. Whether the proliferation is spontaneous or reactive is not clear. Among the imaging techniques, ultrasonography (USG) and magnetic resonance imaging (MRI) are both useful for diagnosis. Delineation of the soft-tissue and local invasion is better seen with MRI than USG, but USG is preferred because of widespread availability and low cost. However, it did not reveal any significant softtissue thickening in this case.
