Chronic breast abscess due to Mycobacterium fortuitum: a case report

<p>Abstract</p> <p>Introduction</p> <p><it>Mycobacterium fortuitum </it>is a rapidly growing group of nontuberculous mycobacteria more common in patients with genetic or acquired causes of immune deficiency. There have been few published reports of <it>Mycobacterium fortuitum </it>associated with breast infections mainly associated with breast implant and reconstructive surgery.</p> <p>Case presentation</p> <p>We report a case of a 51-year-old Caucasian woman who presented to our one-stop breast clinic with a two-week history of left breast swelling and tenderness. Following triple assessment and subsequent incision and drainage of a breast abscess, the patient was diagnosed with <it>Mycobacterium fortuitum </it>and treated with antibiotic therapy and surgical debridement.</p> <p>Conclusion</p> <p>This is a rare case of a spontaneous breast abscess secondary to <it>Mycobacterium fortuitum </it>infection. Recommended treatment is long-term antibacterial therapy and surgical debridement for extensive infection or when implants are involved.</p

Successful radiation treatment of anaplastic thyroid carcinoma metastatic to the right cardiac atrium and ventricle in a pacemaker-dependent patient

Anaplastic thyroid carcinoma (ATC) is a rare, aggressive malignancy, which is known to metastasize to the heart. We report a case of a patient with ATC with metastatic involvement of the pacemaker leads within the right atrium and right ventricle. The patient survived external beam radiation treatment to his heart, with a radiographic response to treatment. Cardiac metastases are usually reported on autopsy; to our knowledge, this is the first report of the successful treatment of cardiac metastases encasing the leads of a pacemaker, and of cardiac metastases from ATCs, with a review of the pertinent literature
