Granulocytic sarcoma of the dorsal spine in an aleukemic patient.

The spine is an uncommon location for granulocytic sarcoma that is an extramedullary deposit of malignant myeloid cells. Very few cases are reported in literature as occurring in aleukemic patients. Due to histopathological similarity with lymphoma, Ewing's sarcoma, and multiple myeloma, the diagnosis is often missed. We describe a 22-year-old man presented with worsening dorsal compressive myelopathy in whose treatment was started after initial diagnosis of a lymphoma and who has had no leukemic conversion even after 2 years.
