Liposarcoma (LPS) is a rare malignant tumor, but it is also one of the most common adult soft-tissue sarcomas. Myxoid liposarcoma (MLPS) accounts for 30% of all LPS cases. Diagnosis during pregnancy and the puerperium is very rarely reported, and only a few cases have been reported in the thigh.
We report the case of a 36-year-old female patient on the 11th day of the puerperium after a cesarean section. The patient presented to the gynecology ward owing to the sudden appearance of a tumor in the medial part of her right thigh. The lesion was non-painful, mobile, soft, approximately 20 cm in diameter, and protruded above the level of the rest of the thigh surface. A suspicion of hematoma was raised. The final diagnosis was high-grade MLPS.
An MLPS diagnosis is uncommon in female patients and even rarer during pregnancy. This case represents a novel occurrence, as the first instance in which symptoms manifested during the puerperium. Proper treatment and early detection could improve disease outcomes.
脂肪肉瘤（LPS）是一种罕见的恶性肿瘤，但也是最常见的成人软组织肉瘤之一。黏液样脂肪肉瘤（MLPS）占所有LPS病例的30%。妊娠和产褥期的诊断报道非常罕见，仅有少数病例报道发生于大腿。
我们报告一例36岁女性患者，剖宫产术后第11天产褥期发病。患者因右大腿内侧突然出现肿物入住妇科病房。病变无疼痛，可活动，质地柔软，直径约20cm，高出大腿其余表面。起初怀疑为血肿。最终诊断为高级别MLPS。
MLPS在女性患者中并不常见，在妊娠期更为罕见。该病例为首次报道产褥期出现症状的MLPS，属新发病例。恰当的治疗和早期诊断可改善疾病预后。
