Primitive neuroectodermal tumor (PNET) is most common in the second decade of life. Congenital PNET is very rare. Ocular metastasis of PNET is likewise exceedingly rare; with only 5 previously published cases. We report an unusual congenital PNET of the face, which metastasized to subcutis, eyes, and brain. The primary tumor responded to chemotherapy (vincristine/doxorubicin/cyclophosphamide) with metachronous progression of ocular lesions. A therapeutic trial of intraocular bevacizumab showed no efficacy on intraocular lesions. Eventually the patient developed cerebral metastasis, and second line therapy with topotecan/cyclophosphamide was initiated. The tumor progressed and the patient died after acute herniation.

Ewing sarcoma family tumors (ESFT) pose diagnostic challenges, which largely depend on the primary site of involvement and tumor stage. Despite advancements in treatment, metastatic ESFTs remain associated with poor outcomes. This case describes a 21-year-old woman who, in July 2022, presented with a left breast mass identified through ultrasound and CT scan, along with abdominal distention.
