Mucosal infection with Tsukamurella species following nasal septum procedure: a rare case report.

INTRODUCTION AND

IMPORTANCE

Tsukamurella species are rare, aerobic, gram-positive bacteria known to cause infections, primarily in immunocompromised individuals. This case report presents a rare instance of a mucosal infection caused by Tsukamurella species following a nasal septum procedure in an immunocompetent patient.

CASE PRESENTATION: A 51-year-old man with a history of multiple hereditary exostosis, allergic rhinitis, and recent nasal fracture repair presented with persistent fevers and low back pain. Postoperatively, he developed sinus pain and small oral lesions, initially treated with antibiotics for presumed sinusitis. Despite treatment, his fever persisted, leading to an emergency department visit. Laboratory tests indicated sepsis, but a CT scan of the sinuses showed no sinusitis. Despite broad-spectrum antibiotics, the patient's fever continued. On admission day 9, nasal endoscopy and culture identified Tsukamurella species. The patient was treated with augmentin, fluconazole, and levofloxacin, leading to the resolution of symptoms and discharge with ongoing treatment.

CLINICAL DISCUSSION: Tsukamurella species are uncommon pathogens that are often associated with bacteremia in immunocompromised individuals. This case highlights the diagnostic challenges and the importance of considering unusual pathogens in postprocedural infections, even in immunocompetent patients. Accurate identification and appropriate management are critical in improving outcomes for patients with Tsukamurella infections.

CONCLUSION

This case underscores the need for vigilance in diagnosing rare infections like Tsukamurella, even in immunocompetent individuals. The successful resolution with combination therapy highlights the importance of appropriate antibiotic selection in managing such infections.
