“…Giant retroperitoneal lipomas in adults are scarce, with a total number of 17 cases described in the literature since 1980 [ 5 - 20 ] (Table 1 ). Subcutaneous lipomas are associated with hypercholesterolemia [ 21 , 22 ], obesity [ 23 - 25 ] and trauma [ 26 ], whereas such data does not exist for retroperitoneal lipomas. Moreover, the patient was not described positive for any of these factors.…”

En-bloc resection of a giant retroperitoneal lipoma: a case report and review of the literature

BackgroundRetroperitoneal lipomas are an extremely rare condition with only 17 cases described in the literature since 1980. They can reach enormous size and cause significant abdominal symptoms. The most important differential diagnosis is the well-differentiated liposarcoma, which preoperatively often may not definitely be ruled out.Case presentationWe present the case of a 73 year-old Caucasian patient with a giant retroperitoneal lipoma of 9 kg measuring 55 cm in diameter. The patient presented with abdominal pain and swelling that had been slowly progressive for the last 15 years. On computerized tomography an immense retroperitoneal tumor was revealed. Intraoperatively, the tumor did not show any signs of infiltrative growth, therefore sole tumor extirpation was performed.ConclusionRetroperitoneal lipomas are not clearly distinguishable from well-differentiated liposarcomas on imaging and even biopsies may be misleading. Moreover, abdominal symptoms, i.e. pain, obstipation and dysphagia may occur due to mechanical displacement. Therefore, surgical exploration with complete oncological resection is the therapy of choice if malignity cannot be ruled out.Electronic supplementary materialThe online version of this article (doi:10.1186/s13104-015-1038-7) contains supplementary material, which is available to authorized users.

“…Metabolic factors, including hypercholesterolemia and obesity, are generally associated with an increased risk of developing subcutaneous lipomas. Still, there are no data to link it to an increased risk for the retroperitoneal area [40][41][42]. Aust et al also reported traumatic events related to subdermal location [43].…”

The pure retroperitoneal lipoma is a sporadic benign tumor originating from the mesenchymal tissue. There are only a few data in the literature. The technique available at this moment cannot establish a clear distinction between a benign adipose mass and a low-grade liposarcoma. This study presents the case of a 53-year-old man presenting computed tomography (CT) and magnetic resonance imaging (MRI) findings that revealed a giant retroperitoneal fatty tumor of 365/210/165 mm dimensions, suspected of malignancy. The patient's medical history, clinical data, and blood tests are more likely inclined to a benign condition. Liposarcoma couldn't be excluded preoperatively. The patient underwent an open surgical procedure respecting the oncological principles, with complete resection of 6400 g of retroperitoneal adipose tumor that also affected the surrounding organs' normal abdominal anatomy. The tumor was relatively well delimited without any signs of local invasion or infiltration. Three solid masses described on the MRI were identified upon dissection and sent separately for histological examination. The result indicated a giant retroperitoneal lipoma with benign characteristics. Facing imagistic difficulties to distinguish lipoma from liposarcoma clearly, and the inconclusiveness of fine-needle biopsies, oncological resection remains the only option as a diagnostic method and curative treatment.

“…Lipomas are very slow growing and may reach a size of 5-10 cm. A lipoma having length more than 10 cm or weighing more than 1000 g is defined as giant lipoma [3].…”

Introduction: The deep intermuscular lipomas of medial or adductor compartment are very rare. Occasionally these lipomas can achieve a giant size. Case Report: We report a case of giant lipoma of adductor compartment of left thigh in a 50-year-old man. The giant size lipoma presented a diagnostic dilemma as it was subfascial and extended to two compartments of thigh, medial, and anterior. Also, it had to be differentiated from well-differentiated liposarcoma. Magnetic resonance imaging (MRI) could analyze the size and extent of lipoma. Fine-needle aspiration (FNA) reported the soft tissue mass as lipoma. The patient was treated by excision of the giant lipoma. The challenge was complete removal along with its extensions into adductor canal. Conclusion: A giant size lipoma of medial compartment of thigh achieving a large size of 30 cm long with extension into adductor canal. A careful excision from the neurovascular bundle has been done.
