SUMMARY Streptococcus mitis is a commensal organism of the human oropharynx that rarely causes infection in healthy individuals. Herein, we describe a previously healthy 35-year-old woman who presented with acute pyogenic flexor tenosynovitis of the left index finger due to S. mitis infection. The patient's infection was treated successfully via surgical and medical interventions, and during fo...

Mycobacterium marinum is an unusual atypical mycobacterium with low pathogenicity for humans in comparison with Mycobacterium tuberculosis. Among the non-tuberculous mycobacterial pathogens, Mycobacterium marinum is the most common pathogen to cause skin infections. Mycobacterium marinum infection causes chronic cutaneous lesions and in some cases deeper infections such as tenosynovitis, septic...

Musculoskeletal infections are commonly encountered in clinical practice. This review will discuss the ultrasound appearances of a variety of musculoskeletal infections such as cellulitis, infective tenosynovitis, pyomyositis, soft-tissue abscesses, septic arthritis, acute and chronic osteomyelitis, and post-operative infection. The peculiar sonographic features of less common musculoskeletal i...

A 20-year-old previously well woman presented to the emergency department with classical signs of acute flexor tenosynovitis, 4 hours after a minor puncture wound over the volar aspect of her right middle finger distal interphalangeal joint. Exploration of the flexor sheath in theatre revealed frank blood within the sheath and extension of the puncture wound through the profundus tendon into th...

Mycobacterium terrae complex has been recognized as a cause of tenosynovitis, with M. terrae and Mycobacterium nonchromogenicum reported as the primary etiologic pathogens. The molecular taxonomy of the M. terrae complex causing tenosynovitis has not been established despite approximately 50 previously reported cases. We evaluated 26 isolates of the M. terrae complex associated with tenosynovit...

Remitting seronegative symmetric synovitis with pitting edema (RS3PE) is a rare syndrome characterised by acute onset of symmetrical distal and tenosynovitis, associated severe the dorsum hands feet, seronegativity for autoimmunity dramatic response to glucocorticoids. First described McCarty et al. in 1985, RS3PE reported mostly elderly males, but it can also rarely occur young people. Althoug...
