Resection of liposarcoma of the greater omentum: a case report and literature review

ConclusionThe diagnosis of liposarcoma with a lipomatous tumor is challenging, and resection should be considered for huge intra-abdominal lipomatous tumors.

DiscussionThe prevalence of adipose tumors is underestimated within hand and wrist tumors. The most common way these tumors are discovered is due to compressive neuropathy with paresthesia and/or dysesthesia. While these tumors are nearly always benign, this does not justify ignoring the opinion of the multidisciplinary tumor board or underestimating the small possibility of the lesion being a liposarcoma.Level of evidenceIV, retrospective, single-center study.

CONCLUSION: Liver nodules should be characterised with regard to underlying liver condition, MRI characteristics and contrast enhancement pattern, including hepatobiliary phase. In many cases, identification of fatty content may help narrowing the differential diagnosis. PMID: 32008550 [PubMed - in process]

Authors: Malinauskaite I, Hofmeister J, Burgermeister S, Neroladaki A, Hamard M, Montet X, Boudabbous S Abstract Distinguishing lipoma from liposarcoma is challenging on conventional MRI examination. In case of uncertain diagnosis following MRI, further invasive procedure (percutaneous biopsy or surgery) is often required to allow for diagnosis based on histopathological examination. Radiomics and machine learning allow for several types of pathologies encountered on radiological images to be automatically and reliably distinguished. The aim of the study was to assess the contribution of radiomics and machine learn...

Rationale: Oral liposarcoma is an extremely rare lesion that is often clinically misdiagnosed as a benign lesion because of its asymptomatic and indolent clinical course. we report a case of atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDL) of buccal mucosa, provisionally diagnosed as lipoma. Patient concerns A 97-year-old female was referred to dentistry and oral surgery department with an asymptomatic mass on the right buccal mucosa which had been present for an unknown period of time. Diagnosis Magnetic resonance imaging demonstrated a well-circumscribed lesion at the right buccal mucosa, and a...

Publication date: June 2020Source: Interdisciplinary Neurosurgery, Volume 20Author(s): Hemant Sah, Dipendra Kumar Shrestha, Binod Rajbhandari, Amit Bahadur Pradhnang, Sushil Krishna ShilpakarAbstractSpindle cell lipomas (SCL) are rare, slow-growing and benign fatty neoplasms, which are commonly located in the subcutaneous layer of the posterior neck and upper back. Due to the similarities in the clinicoradiological features, it needs to be differentiated from other benign and malignant soft tissue tumors including liposarcoma. Preoperative diagnosis is usually difficult; and, hence, a histopathological study is required to...

ConclusionAlthough ossifying lipomas are very rare, it is important to keep them in mind when a lesion with adipose tissue in combination with ossification is encountered.

We present a case of a 57-year-old white female with a left upper thigh mass located at the previous surgical site of the resection of a 15 cm, 505-glipoma 10 years ago. Magnetic resonance imaging showed a 1.7 × 3.1 × 2.9 cm soft tissue mass within the subcutaneous adipose tissues of her left upper thigh at the site of previous lipoma resection. No muscle or bone invasion was identified. The clinical impression was lipoma versus liposarcoma. The mass was surgically removed, and gross examination showed a tan-pink, well-demarcated soft mass with scalloped edges noted within the...

CONCLUSION: Radiomics is a promising, non-invasive method for differentiating between WDLPS and lipoma, outperforming the scores of the radiologists. Further optimization and validation is needed before introduction into clinical practice. PMID: 31747074 [PubMed - in process]

CONCLUSIONS: Currently, there is no evidence-based recommendation available regarding the management of lipomas detected during open or laparoscopic inguinal hernia surgery. Due to the extremely low risk of the presence of a liposarcoma routine histologic examination cannot be recommended unless the diameter exceeds 10 cm.

ConclusionsThere is a significant relationship between a radiomics signature, consisting of a combination of quantitative MRI features, and the MDM2-amplification status. Although further optimization and validation is needed for the transition to clinical practice, radiomics has appeared to be a promising, non-invasive approach for the classification of WDLPS and lipomas.AcknowledgementM.Vos and M.P.A.
