Sclerosing osteomyelitis of Garré is a rare inflammatory pathology characterized by cortical thickening and loss of the medullary canal. Typically, this pathology affects the mandible. However, the involvement of long bones, such as the femur and tibia, is also possible. This condition predominantly affects children and young adults, especially females, and commonly emerges before age 25, with an average onset age of 16 years. The disease is characterized by an insidious onset, causing local pain, distention of the affected bone, and a moderately increased erythrocyte sedimentation rate. We aim to report a unique case involving a 25-year-old Hispanic male presenting with a one-year insidious onset of left anterior lower leg pain. The patient's clinical course, laboratory findings, and imaging results are discussed. Despite a three-month trial of conservative management, symptomatic relief was elusive, prompting a left tibia core biopsy. Biopsy results revealed an inflammatory-reactive process with a xanthogranulomatous reaction. The continuation of conservative measures post-biopsy led to significant symptom resolution, highlighting the potential efficacy of histopathological examination. This case contributes to the limited literature on adult sclerosing osteomyelitis of Garré, particularly in long bones and among Hispanic individuals. Successful management through biopsy and conservative treatment provides valuable insights into therapeutic options for this rare condition.
