[Disseminated tuberculosis with osteomyelitis of the right little finger as the first manifestation: a case report].

The clinical data of a child with disseminated tuberculosis with osteomyelitis of the right little finger as the first manifestation who was admitted to Tianjin Children's Hospital on April 8, 2023 were retrospectively analyzed. The child, a 14-year-old female, presented with osteomyelitis of the right little finger as the first manifestation. She still had recurrent fever after focal incision and drainage. She was referred to our hospital. The samples from multiple sites were positive for molecular biology detection of Mycobacterium tuberculosis. She was considered as disseminated tuberculosis and was given anti-tuberculosis treatment. The child has recovered well. Pediatric disseminated tuberculosis has variable clinical manifestations and lacks specificity. It is often misdiagnosed and has a high mortality rate. Clinicians should improve their understanding of the disease and ensure early diagnosis and treatment.
