“…Lipomas are common benign tumors, and during treatment of deep-seated lipoma, differential diagnosis between well-differentiated liposarcomas should be considered [ 1 ] . Lipomas can be treated successfully with local or marginal excision, whereas well-differentiated liposarcomas need to be treated with wide local excision because of the high rate of local recurrence (10–52%) [ 2 ].…”

“…Lipomas of the intrathoracic cavity are relatively rare and are reported to be located in the intracardiac, pleural and intramuscular regions. There are few reports of chest wall lipomas, and it is always clinically difficult to distinguish them from liposarcomas [ 1 ]. Herein, we report a case of lipoma of the chest wall preoperatively diagnosed as liposarcoma due to malignant feature based on radiological image and intraoperative findings.…”

Lipomas are common benign tumors, which are usually located in the subcutaneous tissue. It is relatively rare for lipoma to occur in the intrathoracic cavity, and it is clinically difficult to distinguish it from liposarcoma. We present the case of a 72-year-old man with a chest wall tumor preoperatively diagnosed as liposarcoma, with tumor enlargement with radiological image change to heterogenous and 18F-fluorodeoxyglucose positron emission tomography uptake. The tumor was resected along the chest wall, lung and diaphragm because of dense adhesions. The tumor was diagnosed as lipoma with fat necrosis and inflammatory changes.

The greater sciatic, lesser sciatic and obturator foramina are openings in the pelvis through which pelvic lesions can herniate, leading to the formation of rare dumbbell tumours. We present the case of a man in his late 60s, who presented with obstructed defecation. A per rectal examination revealed a palpable right sided rectal mass. MRI pelvis identified a dumbbell lipoma traversing the right sciatic foramen, with a pelvic component causing displacement of the rectum and a gluteal component impinging on the sciatic nerve. The lipoma was successfully removed by a multidisciplinary team using a dual approach: the pelvic component was excised laparoscopically, and the gluteal component was removed by an open approach. Comprehensive knowledge of pelvic anatomy is required to safely and accurately excise lesions in this region. Laparoscopic approach offers clear advantages over the open approach, while yielding similar results.

Background Intramuscular hemangioma (IMH) is an uncommon type of hemangioma, and primary IMH of the intercostal muscle is even rarer. Only a few reports describe IMH of the intercostal muscle, and there are no review articles on this topic. We report our experience with a younger female patient, who underwent video-assisted thoracic surgery with tumor resection and review the previous literatures of intercostal IMH. Case presentation An asymptomatic 17-year-old woman showed a 29-mm, homogeneous, intrathoracic nodule in the left chest wall, attached to the second and third ribs on computed tomography. We performed exploratory thoracoscopic surgery and the tumor was excised without surrounding rib resection. Histopathologic examination of the surgical specimen revealed proliferation of small blood vessels within the surrounding striated muscle, leading to the diagnosis of intercostal IMH. The surgical margin was negative. The patient’s postoperative course was uneventful, and there has been no evidence of recurrence for more than 18 months after surgery. Conclusions We describe a case of intercostal IMH, who received tumor resection with clear excision margin without surrounding rib resection. Preoperative diagnosis is challenging due to its rarity, but intercostal IMH should be recalled as a differential diagnosis of chest wall tumor. Tumor excision without surrounding rib resection is acceptable for intercostal IMH, when there is a good possibility of achieving negative surgical margin.
