## TL;DR

A rare case of myxoid liposarcoma in a woman's thigh during the early postpartum period is reported and reviewed.

## Contribution

This is the first reported case of myxoid liposarcoma diagnosed during the puerperium.

## Key findings

- Myxoid liposarcoma is rare in women and even rarer during pregnancy or the puerperium.
- Early detection and proper treatment are crucial for improving outcomes in such cases.
- The case highlights the importance of considering sarcomas in differential diagnoses during postpartum periods.

## Abstract

Background: 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. Case presentation: 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. Conclusions: 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.
