Stenotrophomonas Necrotizing Tonsilitis in a Pediatric Patient: A Rare Presentation With Upper Airway Obstruction.

Stenotrophomonas maltophilia is notorious for its intrinsic resistance to many commonly used antibiotics, making it a particularly challenging pathogen to treat. It often causes severe opportunistic infections in immunocompromised and hospitalized patients. The potential for this infection to become fulminant with high mortality rates in both adults and children necessitates a multidisciplinary approach. Prompt initiation of appropriate antibiotic therapy can be lifesaving. In this case report, we present a rare instance involving an eight-month-old previously healthy infant diagnosed with necrotizing tonsillitis and a retropharyngeal abscess, which led to upper airway obstruction. Intraoperative tissue cultures identified this highly virulent gram-negative bacillus. The report details the medical and surgical management that resulted in the patient's complete recovery.

Rare Extranodal Manifestation of Rosai-Dorfman Disease Presenting as Nasal Obstruction and its Management.

Rosai-Dorfman disease (RDD) is a rare and benign lymphoproliferative disorder that commonly presents as painless, bilateral neck swelling. Extranodal presentations are considered rare, but the most common extranodal locations involved include skin, subcutaneous followed by nasal/paranasal sinuses. Although it is a benign condition, it may be mistaken as a malignant lesion and requires a biopsy for diagnostic confirmation. In this study, we report a rare case of RDD with bilateral neck node and nasal/paranasal sinus involvement which initially presented with bilateral nasal obstruction. And, we reviewed the management in this unusual case and discussed the helpful role imaging studies play in the further workup and subsequent follow-up to treatment response.
