PATHOLOGY: IMT of the penis. A 46-year-old man with a mass in the penis came to our hospital. He related more than 6 years of slow growth of the mass with no suspicious associated symptoms. a, b Axial and coronal reformations of non-enhanced CT. Solid, well-defined, heterogeneous penile mass is shown. c, d Axial and coronal reformations of enhanced-CT after the injection of intravenous contrast on portal phase. The penile mass presents an heterogeneous and peripheral enhancement. e Surgical sample obtained after partial penectomy. Macroscopic view showed an heterogeneous aspect due to the mixture of tissues (solid tumour, lipoid component and areas of haemorrhage). f Microscopic study confirmed a mesenchymal tumour composed of fusiform cells, some of them multinucleated, with round or elongate nucleus. Prominent infiltrate of plasmatic cells and focal areas of haemorrhage were also found. No mitotic figures were observed
