The Importance of Hematoxylin Eosin Staining Technique in Accurate Diagnosis of Tumors

Retroperitoneal tumors, benign or malignant derive from a variety of tissues, so their classification is primarily based on this histological parameter (tissue origin). Retroperitoneal tumors, although very rare, raise interests by the specific characteristics from the space where they develop, causing serious problems for diagnosis and treatment. Autoimmune Hemolytic Anemia is a common complication of malignancy, but may be secondary to the retroperitoneal tumors. We present the case of a woman, 42 years old, who is admitted in the Hematology Clinic for abdominal pain and marked asthenia. The abdominal CT objectified presence of expansive tumor on the caudate lobe liver, well defined, with mass effect on portal trunk. She is transferred to a Surgery Clinic where, although the investigations oriented towards a liver tumor, during surgery it was discovered the presence of a tumor that did not belong to the liver parenchyma but retroperitoneal tissue. The pathological anatomy confirmed the diagnosis of benign lesion tumor with conjunctiva behavior. There are discussed the relationship between autoimmune hemolytic anemia and retroperitoneal tumors, diagnostic problems but also the therapeutic methods addressed in this case, represented by the surgical act, performed as a diagnostic and therapeutic purpose. Retroperitoneal tumors are rare injuries, but make delicate problems of diagnosis and therapeutic attitude.
