Well-differentiated liposarcoma of the cheek misdiagnosed for lipoma: A case report.
Article in International journal of surgery case reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionLiposarcoma is the most common sarcoma entity and accounts for 17% to 30% of soft tissue sarcomas. There are several histological types including well-differentiated liposarcoma. This paper aims to underline the interest of immunohistochemical and cytogenetic studies to diagnose well-differentiated liposarcoma and to show the delicacy of performing a surgical procedure in the cheek area. CASE PRESENTATION: The authors report the case of a 48-year-old female patient who presented with the recurrence of a right jugal mass initially diagnosed as a lipoma on the resection specimen. The patient was reoperated 5 years later and further immunohistochemical and cytogenetic studies confirmed the diagnosis of well-differentiated jugal liposarcoma. DISCUSSION: Sarcomas are rare malignant tumors of mesenchymal origin, arising from connective and supporting tissues. It should be noted that certain MRI features can distinguish liposarcoma from lipoma. Conventional histology and immunohistochemistry are the basic means for the diagnosis and classification of liposarcomas. However, molecular biology can add to the pathologist's analysis and rule out differential diagnoses Liposarcoma of the maxillofacial region has a better prognosis compared to other parts of the human body.
conclusionThis paper underlines the interest of complementary immunohistochemical and cytogenetic studies to differentiate well-differentiated liposarcoma from lipoma as well as the potential for local recurrence of liposarcomas.
