An Unusual Source of Sinonasal Disease in an Immunocompromised Patient: A Case Report of the Clinical Presentation, Diagnosis, and Treatment of Acanthamoeba Rhinosinusitis

Chronic nasal crusting is a commonly encountered entity in an otolaryngology office. Progressive, extensive nasal crusting with erosion is relatively unusual, however. We present the case a 58-year-old renal transplant patient with a history of vasculitis and immunosuppression who presents with subjective headache and facial pain, nasal crusting, and isolated left ethmoid sinusitis. She developed extensive intranasal necrosis and underwent multiple endoscopic sinus surgeries with intraoperative biopsies, which played a critical role in her workup and eventual diagnosis of Acanthamoeba rhinosinusitis. Although she endured a difficult course, proper diagnosis and treatment allowed for her recovery over time. The differential diagnosis for intranasal necrosis is often broad. This case highlights the wide range of etiologies to be considered in a patient with extensive nasal crusting and erosion/necrosis, and the importance of thorough diagnostic evaluation in these patients, especially those in an immunocompromised state.

Clinical and pathologic characteristics of intranasal abuse of combined opioid-acetaminophen medications

BACKGROUND

The nonmedical abuse of prescription opioids via intranasal administration is a growing problem. The objective of this study is to investigate of the typical presentation of intranasal opioid-acetaminophen abuse and outline optimal therapy.

METHODS

This study was a retrospective chart review. Patients with intranasal pathology from inhalation of combined opioid-acetaminophen medications (COAMs) from 3 academic otolaryngology practices in western Pennsylvania from January 2012 to October 2012 were included in the review.

RESULTS

Seven adults ranging in age from 23 to 46 years were identified with nasal complaints from the intranasal inhalation of COAMs. All patients presented with nasal pain and were found to have fibrinous necrotic nasal mucosa involving the posterior nasal cavity and nasopharynx. Of the 7 patients, 6 (85.7%) presented with a septal perforation. Pathology and culture revealed fungus in 85.7% of the patients; however, no invasive fungal disease was noted in any of the specimens. Patients did not improve with either systemic or topical antifungal therapy. Polarizable material characteristic of talc used as a tablet binder was present in the histopathology of 4 of 7 (57.1%) patients. Patients who abstained from intranasal drug use along with serial debridement demonstrated the greatest improvement.

CONCLUSION

Intranasal COAM abuse causes nasal pain, tissue necrosis with potential septal and palatal perforation, and noninvasive fungal colonization. Antifungal therapy was of no benefit in the current series of patients. Current therapy should focus on recognition of the etiology of patients' pathology and encourage abstinence from intranasal use of these drugs along with serial debridements.
