CASE: The authors report a case of an 6-year-old pediatric patient with a history of acute onset of proptosis of his right eye. He was admitted at hospital 6 months ago for proptosis concomitant with orbital trauma. Computed tomography scan demonstrated a mass involving the right orbit, right maxillary sinus, and zygoma with endocranial extension. RESULTS: Incisional biopsy of the mass revealed after of histopathologic and immuno-histochemical evaluation a T-cell lymphoblastic lymphoma. Systemic examination and bone marrow aspirate show a acute lymphoblastic leukemia. The patient was treated with LMT96 Protocol. A complete Remission was observed after 13 months of follow up. CONCLUSION: Primary T-cell lymphoblastic lymphoma of the orbit is a rare entity in any age group, but it is very rare in children. When tumors occurs in the orbit, it presents a challenging diagnosis problem, especially in pediatric patients.
