Diagnosis and Treatment of Soft Tissue Tumors: Changes, Challenges and Strategies, Springer International Publishing Ag, ss.385-391, 2025
Infantile Fibrosarcoma is a malignant fibroblastic tumor that has a locally aggressive behavior and is rarely metastatic. While diagnosis in utero is occasionally possible, most cases are diagnosed within the first year of life, and the most involved sites are the extremities. Tumors can reach huge sizes, eventually involving or even replacing the whole extremity part. The tumor borders are usually infiltrative. Wide local excision is the treatment of choice. Preoperative chemotherapy has an essential role when straightforward excision is not feasible. In this chapter, we present the case of a newborn female patient who had been diagnosed with a sizeable lower leg mass in utero and kept under surveillance with ultrasonography until birth. A trucut biopsy right after birth revealed the diagnosis of infantile fibrosarcoma. While inoperable at birth, limb salvage surgery was only deemed possible following neoadjuvant chemotherapy.
