  • Eosinophilic esophagitis (EoE) is an immune-mediated disorder that may be related to exposure to additive chemicals in crops, air pollutants, or supplements found within livestock. Co-occurring allergic or atopic diseases including atopic dermatitis, food allergies, and asthma are also commonly seen in 70% of cases and help guide diagnosis. Diagnosis of EoE requires eosinophilic infiltration greater than 15 eosinophils per high power field (HPF) with endoscopic evidence of abnormal esophageal changes. Here, we discuss a rare presentation of food bolus impaction secondary to EoE after ingestion of a nasal decongestant and antihistamine pill that has previously never been described in the literature. A 22-year-old male with no significant past medical history presented to the emergency department (ED) with a chief complaint of a sudden onset respiratory distress, regurgitation of clear oral secretions, and globus sensation post ingestion of a fexofenadine-pseudoephedrine tablet. Prior to intake of the capsule, the patient was consuming liquids and solids appropriately. The patient was afebrile, hypertensive at 172/114, and found to have a normal heart rate of 88 bpm and a respiration rate of 18 breaths per minute. An esophagogastroduodenoscopy (EGD) was performed, which revealed a fexofenadine-pseudoephedrine capsule at 23 cm from the incisors along with a superficial ulceration at the corresponding level in the esophagus. The foreign body was successfully removed using raptor forceps. Further visualization demonstrated trachealization of the esophagus and furrowing and severe narrowing (< 10mm), which raised suspicion for EoE. Proximal biopsy indicated 16 intraepithelial eosinophils per HPF within the squamous epithelium, likely compatible with EoE. The patient tolerated the procedure well and was discharged on an eight-week course of proton-pump inhibitors. EoE is defined as an immune-mediated esophageal disease characterized histologically by eosinophil-predominant inflammation. Our patient was reported to have up to 30 eosinophils per HPF from the proximal esophageal biopsy, which satisfies the requirements for an EoE diagnosis. Based on the current literature review, there have been no other reported cases of symptomatic food bolus impaction secondary to EoE after ingestion of antihistamines.
