Case report on the coincidence of retroperitoneal dedifferentiated giant liposarcoma and renal papillary cell carcinoma
Abstract
The most common histological type of retroperitoneal sarcomas
is liposarcoma. Renal papillary cancers account for approximately
10% of all known renal cell cancers and nephrectomy is the
preferred choice for the treatment in suitable cases. In this report,
we presented a concurrency of giant retroperitoneal liposarcoma
and renal papillary cancer in a 61-year-old male patient. He was
referred to our clinic with complaints of abdominal distension
and pain. Computed tomography (CT) scan, magnetic resonance
imaging (MRI) and positron emission tomography-computed
tomography (PET-CT) revealed a giant mass filling intraabdominal
and retroperitoneal space, approximately 50x30 cm in size and also
a separate mass which is 6x8 cm in size in the upper pole of the left
kidney. The giant mass was excised in two separate pieces. After
frozen section procedure, nephrectomy was performed for mass
arising from the left kidney. Histopathological analysis of the large
masses, revealed dedifferentiated liposarcoma and renal papillary
cellular cancer in the abdomen and left kidney, respectively.
In conclusion, a second primary tumor can be seen in patients
with giant retroperitoneal liposarcoma and coincidence of
these tumors must be determined in the preoperative period for
appropriate treatment.
