ABSTRACT

Mycobacterium peregrinum is a rapidly growing mycobacterium (RGM), subspecies of Mycobacterium fortuitum complex, which can cause infections in the skin, surgical sites, and central lines. It has also been associated with implantable devices such as cardiac devices. Our objective is to present an atypical clinical case of M. peregrinum infection associated with a cardiac device, review the published literature, and highlight the importance of this type of RGM infection to enhance their therapeutic success. Only two other cases have been reported of M. peregrinum infection associated with cardiac devices. Diagnosis and treatment of Mycobacterium peregrinum infection can be challenging, and the literature is scarce. Better understanding and further research should be conducted regarding this infection.

ABSTRACT

Rhinoscleroma is a chronic, slowly progressive granulomatous bacterial infection that is endemic to the tropical world, namely, Central America and Africa. It is occasionally seen in the United States of America (USA). It predominately affects the nasal mucosa but can also involve the rest of the upper respiratory tract. The well-known causative agent for rhinoscleroma is the bacterium Klebsiella rhinoscleromatis, a subspecies of Klebsiella pneumoniae. However, Klebsiella ozaenae can also, albeit very rarely, cause rhinoscleroma. The diagnosis is confirmed by histopathology examination that shows the characteristic Mikulicz cells, considered pathognomonic for this infection. We report a patient with histologically proven rhinoscleroma with pharyngolaryngeal involvement in whom cultures yielded Klebsiella ozaenae. To the best of our knowledge, only two cases of rhinoscleroma due to Klebsiella ozaenae have been reported in the literature to date. Our case illustrates the importance of recognizing this infection in a nonendemic setting such as the USA. A lack of awareness and a delay in the diagnosis of this disease can lead to complications including upper airway obstruction, physical deformity, and, rarely, sepsis. In addition, it must be remembered that the treatment of rhinoscleroma is challenging and requires a prolonged course of antibiotics to achieve a definite cure and avoid relapses.
