Insights
Periorbital swelling in an infant can signal acute lymphoblastic leukemia. Early diagnosis and chemotherapy led to molecular remission in this case.
Area of Science:
- Pediatric Oncology
- Ophthalmology
- Hematology
Background:
- Orbital tumors are rare in infants.
- Periorbital swelling can be an initial sign of serious underlying pathology.
Observation:
- An 8-month-old infant presented with left periorbital swelling and narrowed palpebral aperture.
- Examination revealed a tender medial canthal swelling with periorbital hematoma.
- MRI showed aggressive orbital soft tissue tumor without globe invasion.
Findings:
- Peripheral blood smear revealed blast cells, confirmed by bone marrow aspirate.
- Diagnosis of infant acute lymphoblastic leukemia (ALL) was established.
- Treatment with risk-stratified chemotherapy (Interfant-06 Protocol) was initiated.
Implications:
- Prompt diagnosis and treatment of infant ALL are crucial for favorable outcomes.
- Periorbital swelling can be a presenting sign of infant leukemia, necessitating thorough investigation.
- Successful chemotherapy led to resolution of symptoms and molecular remission.
Abstract:
An 8-month-old Asian infant girl was referred with a 1-week history of left periorbital swelling on a background of a narrowed left palpebral aperture over the preceding 8 weeks. There was no history of chronic illness, fever or other systemic features. Examination revealed a tender and fluctuant medial canthal swelling with associated periorbital haematoma. There were no other ophthalmic findings and neurological examination was normal. A MRI scan of the brain and orbit demonstrated abnormal soft tissue with features of an aggressive tumour in the left orbital region with no globe invasion. Peripheral blood smear revealed blast cells, confirmed by bone marrow aspirate. A diagnosis of infant acute lymphoblastic leukaemia was made. The patient was started on risk-stratified chemotherapy according to the Interfant-06 Protocol The periorbital swelling resolved by day eight following a course of prednisolone, the patient continues on chemotherapy and is currently in molecular remission.

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...
Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
Cells of the Adaptive Immune Response
Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
