[A case of chest wall abscess due to Salmonella newport].

A 18-year-old female with a history of precordial pain was admitted. There was a mass (3.5 x 2.5 cm) in the right inframammary region which was suspected to be chest wall tumor on the basis of CT scan and Ga scintigraphy findings. Exploratory surgery, consisting of total resection of the tumor without removing the ribs, was performed and revealed an abscess. Culture of pus from the abscess grew Salmonella newport (0 antigen 8, H antigen eh; 1.2). Focal infection with Salmonellosis is discussed. Surgical treatment is necessary in addition to chemotherapy.
