Pseudohypopyon in acute myelogeneous leukemia

Area of Science:

• Ophthalmology
• Pediatric Oncology
• Hematology

Background:

• Uniocular hypopyon, elevated intraocular pressure, and iris nodules are critical indicators of intraocular inflammation in pediatric patients.
• Differential diagnosis for these ocular findings in infants includes trauma, infection, retinoblastoma, and various histiocytic disorders.
• Early identification and accurate diagnosis are crucial for effective management and improved outcomes in pediatric eye conditions.

Observation:

• An 11-month-old boy presented with unilateral hypopyon, elevated intraocular pressure, and iris nodules.
• Initial investigations, including physical examination and laboratory tests, yielded normal results, complicating the diagnostic process.
• The child's condition evolved significantly over a three-week period.

Findings:

• The patient subsequently developed fulminant acute myelogenous leukemia (AML).
• This case underscores a rare and atypical presentation of AML in a pediatric patient.
• Ocular manifestations can precede or coincide with the systemic diagnosis of hematologic malignancies.

Implications:

• This case highlights the importance of considering hematologic malignancies in the differential diagnosis of pediatric uveitis and related ocular findings, even with initially normal investigations.
• Ophthalmologists and pediatricians should maintain a high index of suspicion for systemic diseases presenting with ocular symptoms.
• Prompt recognition of evolving symptoms is critical for timely diagnosis and management of life-threatening conditions like acute myelogenous leukemia.
