Abstract
Inflammatory pseudotumor (IP) is a benign uncommon tumour with uncertainly aetiology. Aetiology may be an inflammatory process due to small traumas, surgery, or malignancy. Some studies showed that patients affected by IP were also affected by wide vasculities and genetics abnormalities, strengthening the hypothesis of an aetiology of this disease from an autoimmune pathology or a true tumour respectively. The bladder localization is the most frequently localisation in the genital-urinary apparatus, while the kidney localization is very uncommon. The IP consist of inflammatory and myofibroblastic cells.
Material and Methods
A 69 years old affected with inhomogeneous mass in the right kidney of about 8 cm, calcify lymph-node of the mesentery of about 28 mm.
Results
The patient was undergone to right nephrectomy and removal of mesenteric lymph-node. Histological issue showed a renal cells carcinoma G2 associated to IP. Mesenteric lymph-node with ossification and associated to IP.
Conclusions
This case is interesting for the simultaneous finding of the IP placed to right kidney and mesenteric lymph-node. Similar wide IP have already described in other studies like true tumour with more biological aggressivity. The differential diagnosis of IP with other neoformations is still difficult. We consider an optimal indication to perform a radical surgery therapy in any case, because IP may be associated with a malignancy and because sometime IP may increases progressively its aggressiveness. The histological diagnosis achieved by bioptical sample may be risky because biopsy cannot exclude all doubt about the existence of a mixed neoformations with IP and malignancy like our case.
