“…According to the literature, the most common retroperitoneal sarcoma is dedifferentiated liposarcoma followed by leiomyosarcoma (45% and 21%, respectively). Rhabdomyosarcoma is far less common in retroperitoneum [16,17]. On H&E, the morphology of retroperitoneal mass was similar to the lung mass.…”

Rhabdomyosarcoma (RMS) is one of the most common soft tissue sarcomas of adolescents and young adults. Histologically, rhabdomyosarcoma is classified into embryonal, alveolar, pleomorphic, and spindle cell/sclerosing rhabdomyosarcomas with further subcategorization. More than 50% of embryonal rhabdomyosarcoma occur within head and neck. The retroperitoneum and pelvis are less common sites of involvement. Embryonal rhabdomyosarcomas affect mainly, but not exclusively, children between birth and 15 years of age. Alveolar rhabdomyosarcoma tends to affect older patients. The usual metastatic sites include lung, lymph nodes, and bone marrow. We are presenting a case of a 25-year-old male patient with symptoms of breathlessness, easy fatigability, and weight loss. On chest imaging, there were multiple lung nodules. A primary diagnosis of undifferentiated malignant neoplasm was made on lung biopsy. On immunohistochemistry, the malignant cells were positive for myogenin, myoblast determination protein 1 (MyoD1), and desmin. They were negative for neuroendocrine, germ cell, epithelial, melanocytic, and lymphoid markers. Further workup showed an abdominopelvic retroperitoneal mass on abdominal computed tomography (CT) scan. The biopsy on the retroperitoneal mass showed similar morphology and immunohistochemical profile. Unfortunately, the patient's condition deteriorated rapidly in the following weeks, and he passed away.

“…Interestingly, no primary testicular mass was identified. Additionally, in the retroperitoneal location of a senior individual, differential diagnosis of mass lesions should also include metastatic carcinoma, melanoma, and dedifferentiated liposarcoma [ 15 ].…”

“…Retroperitoneal pathologic processes might be asymptomatic and often present as large masses at initial imaging evaluation[ 1 ]. Retroperitoneal sarcomas accounts for 9% to 15% of all adult soft-tissue sarcomas[ 2 ], including liposarcoma, leiomyosarcoma, and malignant fibrous histiocytoma/undifferentiated pleomorphic sarcoma[ 3 ]. Retroperitoneal liposarcoma is the second most common, accounting for 45%[ 4 ].…”

BACKGROUND Well-differentiated liposarcoma is the second most common pathologic type of retroperitoneal sarcoma. It is characterized by a huge mass, but multiple organ invasions are common. Surgery is the only treatment option for potential cure. Hyper-accuracy three-dimensional (3D) reconstruction is widely used in robotic partly nephrectomy owing to its ability to visualize overlapping anatomy. CASE SUMMARY A 54-year-old man was admitted for progressive abdominal distension over the preceding 2 mo. Computed tomography revealed a 32 cm × 21 cm × 12 cm lipomatous mass. Hyper-accuracy 3D reconstruction was performed because of the complex relationship between the mass and nearby tissue. The patient underwent surgical resection, and the tumor did not recur for over 16 mo. CONCLUSION Hyper-accuracy 3D reconstruction is useful for operative planning owing to its intuitiveness and precise determination of anatomical structures in both tumors and nearby tissues.
