Inflammatory pseudotumor of pelvic lymph nodes.
Inflammatory pseudotumor of lymph nodes (IPT) is a rare, recently described benign cause of lymphadenopathy. The IPT is composed of a proliferation of spindle cells, small vessels and inflammatory cells without atypia and formed by high and poor cellular areas. This study reports a case of IPT. It was a 50-years-old man in whom the abdominal mass was an incidental finding during exploratory laparatomy. The mass was a lymphadenopathy measuring 12 x 10 x 5 cm in diameters. Histologic examination revealed IPT of the lymph nodes. The patient has remained asymptomatic for more than 10 months following surgery without any treatment. In conclusion, IPT of the lymph nodes is being recognized increasingly and should be considered in the differential diagnosis of lymphadenopathies. Inflammatory pseudotumor (IPT) of the lymph nodes resembling the IPT of other organs was recently described as a possible cause of lymphadenopathy. Histologically, the process showed a proliferation of spindle cells associated with a mixture of polymorphic inflammatory cells and small blood vessels involving the connective tissue framework (hilum, trabecula, capsule) of the lymph node. In this report, the case of a patient with IPT of pelvic lymph nodes is presented with the clinical and pathological features.
