Soft tissue sarcomas represent less than 1% of all human neoplasms. One-third of malignant tumors that arise in the retroperitoneum are sarcomas and liposarcoma is the most common retroperitoneal sarcoma. More often than not, patients report late to the hospital due to the slow progress and few late symptoms. Thus, the tumor is known to grow to enormous sizes. Here, we report a case of giant retroperitoneal liposarcoma weighing more than 7 kgs.

Malignant proliferating trichilemmal tumor (MPTT) is a rare cutaneous tumor predominantly affecting the scalp, eyelids, neck and face of elderly women. It is a large, solitary, multilobulated lesion that may arise within a pilar cyst. These tumors are largely benign, often cystic, and are characterized by trichilemmal keratinization. However, at times, the tumor has an aggressive clinical course and a propensity for nodal and distant metastases. Wide local excision with a 1 cm margin of normal tissue is the treatment of choice. Adjuvant chemotherapy and radiotherapy have been occasionally used to prevent recurrence in MPTT. This is a case report of a recurrent malignant trichilemmal tumor over scalp in a young female patient with nodal metastasis.
