 Epithelioid sarcoma is a rare1,2 soft tissue sarcoma, uncommon in females3,4 with less chances of occurrence in spine, lumbar region being the rarest13

location. Initial diagnosis is often misleading6,13. Only few cases involving spine5 are reported in literature, most of which have distant metastasis at
presentation. This is a case of a 34 year old lady with abdominal lump, low backache and weakness of both lower limbs since last 2 years.
Neurological examination showed decreased power in bilateral lower limbs. MRI of spine revealed a soft tissue tumor arising from lumbar spine
causing extradural compression and having a large retroperitoneal component. Initially, resection of the tumor was done followed by
histopathology which suggested a benign tumor. Soon, the growth reappeared alongwith neurological deficit. Then, immunohistochemistry review
of the previous slides revealed epithelioid sarcoma of the spine. Whole body 18F–FDG PET/MRI revealed a bulky metabolically active recurrent
mass in the previously operated bed with compression of nerve roots and no distant metastasis. The authors have thus reported a rare case of
recurrent epithelioid sarcoma of lumbar spine and its clinical course along with immunohistochemical and imaging findings.
