Primary lymphosarcoma of the larynx in a child
Insights
A pediatric patient with primary lymphosarcoma experienced persistent airway obstruction. Successful treatment with chemotherapy and irradiation resulted in a disease-free outcome.
Area of Science:
- Pediatric Oncology
- Hematology
Background:
- Lymphosarcoma in pediatric patients can present with airway obstruction.
- Early diagnosis and comprehensive treatment are crucial for managing pediatric cancers.
Observation:
- A young Caucasian female presented with "croup-like symptoms" and persistent airway obstruction.
- Biopsy during laryngoscopy and bronchoscopy confirmed primary lymphosarcoma without metastatic disease.
Findings:
- The patient received induction chemotherapy (vincristine, prednisone) and local irradiation.
- Central nervous system (CNS) prophylaxis included intrathecal methotrexate and cranial irradiation.
- Maintenance therapy over 2.75 years comprised cyclophosphamide, methotrexate, and 6-mercaptopurine.
- The patient experienced only one hospitalization for complications (sepsis, ulceration, bone marrow depression).
- Following treatment discontinuation, the patient has remained disease-free for 27 months.
Implications:
- This case highlights a successful multi-modal treatment approach for pediatric primary lymphosarcoma.
- Aggressive chemotherapy and radiation can achieve durable remission in pediatric airway obstruction cases.
- Effective CNS prophylaxis and maintenance therapy are vital for long-term outcomes in pediatric lymphosarcoma.
Abstract:
A 4 7/12-year-old Caucasian female with a history of "croup-like symptoms" and persistent airway obstruction, was found to have a primary lymphosarcoma by biopsy at the time of laryngoscopy and bronchoscopy. No metastatic disease was found. After an induction course of vincristine, prednisone and local irradiation, she received CNS prophylaxis with intrathecal methotrexate and cranial irradiation. Maintenance therapy, administered over a 2 3/4 year period, consisted of cyclophosphamide, methotrexate, and 6-mercaptopurine. Excluding the diagnostic evaluation, she was hospitalized only once for the management of suspected sepsis, gastrointestinal ulceration and severe bone marrow depression. Since discontinuing treatment 27 months ago, she has remained free of disease.
