Oral Melioidosis in Odontogenic Keratocyst of Mandible.

Melioidosis is a potentially fatal, life-threatening infection caused by the gram-negative saprophytic organism Burkholderia. It is a disease endemic to Southeast Asia and Northern Australia. This infection transmits through direct contact, cutaneous inoculation, inhalation, or ingestion, and patients clinically exhibit abscesses in single or multiple organs. It is clinically under-reported due to a low index of suspicion, lack of diagnostic facilities, and misdiagnosis as tuberculosis. Infections of the musculoskeletal system are exceedingly rare, and clinical presentation may vary from the involvement of femoral bone, palmar tenosynovitis, and parietal bone osteomyelitis secondary to central nervous system involvement. The rarity of the melioidosis to secondarily infect a developmental odontogenic cyst leading to focal osteomyelitis of mandible prompts the clinician toward thorough evaluation for early diagnosis and treatment.
