ABSTRACT
Tumorous calcinosis is a condition characterized by dystrophic calcification in periarticular soft tissues. Its main locations are the shoulder, hip, and metatarsophalangeal joints, but it is rarely found in the spine. Common symptoms include pain, limited range of motion, and extremity weakness. In the spine, surgical resection is indicated for lesions that cause acute, progressive symptoms, or refractory neurological dysfunction. There are few reports of these tumors in the spine, with the largest series comprising 32 cases. The objective of this report is to describe a rare case of tumorous calcinosis of the lumbar spine. A brief literature review is presented, covering the main characteristics of the tumor, differential diagnoses, histological study, and the surgical approach performed through spinal endoscopy. .
