Primary orbital B cell lymphoblastic lymphoma in a toddler mimicking rhabdomyosarcoma: a diagnostic challenge

Area of Science:

• Pediatric Oncology
• Ophthalmology
• Hematology

Background:

• Primary orbital lymphomas are rare in children, accounting for a small fraction of pediatric orbital tumors.
• Orbital lymphomas can mimic other conditions like orbital cellulitis or masses, leading to diagnostic challenges.

Purpose of the Study:

• To report a rare case of primary orbital B cell lymphoblastic lymphoma in a toddler.
• To emphasize the diagnostic difficulties and potential misdiagnosis of orbital lymphomas.

Main Methods:

• Clinical presentation review.
• Radiological feature analysis.
• Histopathological examination.
• Immunophenotyping for definitive diagnosis.

Main Results:

• The case involved a toddler with an initial misdiagnosis of rhabdomyosarcoma.
• Histopathology and immunophenotyping confirmed the diagnosis of primary orbital B cell lymphoblastic lymphoma.
• The rarity of this condition in pediatric patients was noted.

Conclusions:

• Primary orbital B cell lymphoblastic lymphoma is an uncommon pediatric malignancy.
• Early and accurate diagnosis is crucial, requiring a high index of suspicion due to overlapping features with more common orbital tumors.
• Histopathology and immunophenotyping are essential for confirming the diagnosis and guiding treatment.
