Enucleation of schwannoma of the penis with neurovascular bundle sparing using the VTI 20 MHz Microvascular Doppler System
A 48-year-old man had an unremarkable past medical history. His current illness began 8 years prior to medical consultation with a non-painful, progressive increase in volume at the base of the penis in the dorsal region. The patient had adequate erections but was unable to perform coitus due to the presence of a mass. He complained of no other symptomatology. Physical examination revealed an uncircumcised cylindrical penis and a central meatus. A non-painful, mobile, stony hard tumor measuring approximately 6 cm × 5 cm was located at the dorsal region of the base of the penis. It was not fixed to the deep planes and there were no color changes. MRI of the penis identified a round, solid, well-circumscribed tumor with a heterogeneous content and extremely vascularized aspect. It was not dependent on the corpora cavernosa but caused compression and displacement to the left. The penile tumor was completely extirpated using the VTI 20 MHz Microvascular Doppler System, sparing the neurovascular bundles. The histopathologic report and immunohistochemistry study confirmed the diagnosis of Schwannoma of the penis. At follow-up at more than two years, the patient has no signs of tumor activity and erections are adequate.
