Myxoid liposarcoma is a subtype of liposarcoma. This specific subtype can be identified based on its characteristic histological and cytogenetical features. The tumor has a fusion transcript of the CHOP and TLS genes, which is caused by t(12;16)(q13;p11). Most of the fusion transcripts that have been identified fall into three categories, specifically type I (exons 7-2), type II (exons 5-2), and type III (exons 8-2). A total of seven myxoid liposarcomas associated with the rare phenomenon of cartilaginous differentiation have been documented in the literature. Currently, only one of these cases has been cytogenetically analyzed, and the analysis indicated that it was a type II TLS-CHOP fusion transcript in both the typical myxoid liposarcoma and cartilaginous areas. This study presents a second report of myxoid liposarcoma with cartilaginous differentiation, and includes a cytogenetical analysis of both the myxoid and cartilaginous areas.

Liposarcoma of paratesticular origin is extremely rare and preoperative diagnosis is unusual. Myxoid type or liposarcoma is in general less malignant than testicular tumor and orchiectomy with high ligation and wide excision of tumor mass are probably the treatment of choice. We are present a case of myxoid liposarcoma and reviewed literatures.

This is a case of a posterior mediastinal mass in an asymptomatic gentleman, which was resected successfully and he has been disease free for more than a year of follow up. The histopathology findings happen to be a rare occurrence.

Retroperitoneal liposarcoma is an uncommon tumor both in the pregnant and nonpregnant state. Its exact incidence is unknown because of its rarity. Due to its propensity for local recurrence, prognosis depends on histologic subtype and negative margins of resection. Surgery remains the mainstay of treatment, and timing is critical in terms of finding a surgically resectable lesion while balancing fetal risks. This report describes tumor recurrence in a pregnancy with a prior history of surgery for an atypical lipomatous tumor presenting as a retroperitoneal mass. After discussion with the multidisciplinary team, as well as with the patient’s consent, the plan was to defer surgery until 34 weeks, followed by scheduled tumor removal 2 weeks postpartum. She delivered abdominally to a baby girl with a good outcome. Histopathology showed dedifferentiated liposarcoma with a positive tumor margin. The patient has survived at 6-month follow-up and completed four cycles of chemotherapy with doxorubicin, ifosfamide, and mesna. However, surveillance imaging again showed tumor recurrence.
Liposarcoma

Liposarcoma of spermatic cord is a rare malignant tumor. Because preoperative clinical diagnosis is very difficult, final diagnosis is made by postoperative pathologic examination. This tumor grows slowly and tends to recur locally. Therefore radical inguinal orchiectomy with wide local excision appears to be adequate treatment. We report a case of myxoid liposarcoma of right spermatic cord in 35 year-old male with a brief review of the literatures.

Liposarcomas are one of the most common soft-tissue sarcomas in adults. They usually arise in the deep soft tissues, and patients present with large painless masses. Four major types of liposarcomas are generally recognized and have epidemiologic and prognostic differences: atypical lipomatous neoplasm/well-differentiated; myxoid/round- cell; dedifferentiated; pleomorphic variants. Myxoid liposarcoma is the second most common type of liposarcoma, representing 30~40% of all liposarcomas in the extremities. We report a case of myxoid liposarcoma in a 78-year-old man who presented with an asymptomatic, firm, deep-seated mass in the lateral aspect of his left upper arm.
