Insights
Idiopathic hypereosinophilic syndrome (IHES) can manifest as eosinophilic pharyngitis in children. This case highlights the pharynx as a potential target organ in IHES, even with a benign clinical course.
Area of Science:
- Pediatric Hematology
- Immunology
- Otolaryngology
Background:
- Idiopathic hypereosinophilic syndrome (IHES) is a rare disorder characterized by persistent elevation of eosinophils without an identifiable cause.
- Understanding the diverse clinical manifestations of IHES is crucial for timely diagnosis and management.
Observation:
- A 3-year-old child presented with persistent sore throat and pharyngeal exudate.
- Throat cultures were negative, but microscopic examination revealed extensive eosinophilic infiltration in the pharyngeal tissue.
- The child exhibited marked hypereosinophilia and pharyngeal involvement for 14 months, with no other organ systems affected.
Findings:
- The case demonstrates eosinophilic pharyngitis as a potential presenting sign of IHES in pediatric patients.
- Laboratory findings included persistent marked hypereosinophilia.
- Histopathological analysis confirmed significant eosinophilic infiltration of the pharynx.
Implications:
- The pharynx may represent a specific target organ in idiopathic hypereosinophilic syndrome.
- Recognizing eosinophilic pharyngitis in the context of hypereosinophilia can aid in diagnosing IHES.
- This finding contributes to the understanding of IHES's varied clinical spectrum and its potential impact on the upper respiratory tract.
Abstract:
A 3-year-old child with idiopathic hypereosinophilic syndrome (IHES) presented with sore throat and pharyngeal exudate. Recurrent throat cultures were negative and microscopic section of the exudate revealed an extensive eosinophilic infiltration. Fourteen months later, the child still has marked hypereosinophilia and pharyngeal involvement without other organ involvement. Eosinophilic pharyngitis may be a target organ in IHES. The benign clinical course and the laboratory characteristics are described.

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
