ABSTRACT
Primitive neuroectodermal tumor (PNET) is a highly aggressive
malignant neoplasm derived from primitive neuroectodermal
cells. We report the case of a 67-year-old male with right lumbar
pain; imaging suggested renal involvement, but postoperative
histopathology confirmed a retroperitoneal PNET. Due to its
aggressive nature, a comprehensive therapeutic approach
is essential. The publication of similar cases may support
the development of case series that enhance diagnostic
accuracy and multidisciplinary management strategies for this
increasingly recognized rare entity.
