Case Presentation ConferenceChildren’s Hospital of New Orleans
James M. Roth M.D.Evelyn Kluka M.D.
History
• 13 year-old Hispanic male R.G.• Chief Complaint: Headache, Left Ear Pain
with radiation of the pain to the cheek
History of Present Illness
• 1 month history of progressive left sided facial pain and tingling
• Recent stuffy nose with clear discharge• Odynophagia
Past Medical History
• Esophageal Varices• Hematochezia• Jaundice• Cirrhotic liver disease
Past Surgical History
• Liver Transplant 6 months prior to admission
• Left myringotomy by an ENT in Dallas secondary to disequilibrium, tinnitus, and serous fluid collection
Medications
• Bactrim- prophylaxis• Ganciclovir- prophylaxis• Procardia XL• Magnesium • Prednisone• Neoral- Cyclosporine anti-rejection drug• Cellcept-
Allergies/ Immunizations
• No known drug allergies• No immunizations since liver transplant• Immunizations up to date till then
Social History
• Born in Mexico• Lives with mother currently in Dallas
Physical Exam
• Vital Signs normal• General: Awake alert • Ears: Right TM clear; Left TM slightly
reddened with some fluid present• Nose: Reddened inferior turbinates no
drainage
Physical Exam
• Oropharynx: Tonsils 1-2+ symmetric, uvula midline normal tongue mobility tongue soft to palpation
• Neck: Small < 1 cm nodes scattered throughout neck
• Face: Slight swelling to the left midface
Physical Exam
• Neurological: V2 and V3 with decreased sensation on the left side. Remaining cranial nerves grossly intact.
Admission
• Originally evaluated Dallas and CT scan showed a nasal mass
• Admitted by GI/Transplant team and ENT service was consulted for biopsy
MRI
• Mass filling the nasopharynx compressing or encompassing the left Eustachian tube with area of central necrosis
Intraoperative Findings
• Fungating gray mass filling most of the nasopharynx slight more on the left than the right
• Very solid in nature and avascular
Lab Work
• EBV titers IgM elevated• CBC wnl• Chem 7 wnl• PT/PTT wnl
Surgical Pathology
• Large lesion 3.5x1.5x.5 cm• Lymphoid lesion• Polyclonal cells: small mature lymphocytes,
large active immunoblast, T cells, B cells, Strongly EBV positive
Diagnosis
• Post Transplant Lymphoproliferative Disease (PTLD): Polyclonal Variant
PTLD
• The presence of an abnormal proliferation of lymphoid cells
• Highly related to EBV infection• Related to the type of solid organ
transplanted• More common in children• Originally described in 1969 in 5 renal
transplant patients
Pathology
• Several variants from benign polyclonal B cell hyperplasia to malignant monoclonal lymphoma
• The progression to a monoclonal population leads to a more aggressive and malignant tumor
Why transplant patient’s?
• Immunosuppression is targeted against T cells especially cytotoxic T cells
• These cells help to self regulate the immune system
• With certain viral infection you get B cell proliferation
• These cells can progress in an unregulated manner
EBV Infection
• Causes an active B cell proliferation• Linked to Burkitt’s lymphoma and
nasopharyngeal cancer• R.G. was originally seronegative prior to
transplantation• His runny nose and sore throat may have
represented a recent EBV infection
Common Presentation
• Mononucleosis type infection• Febrile illness with leukopenia• Focal organ system failure
– GI tract: endoscopy, CT scans– CNS: lumbar puncture– Lymph node involvement
Solid Organ Transplant
• Renal- 1%• Liver- 2-3%• Heart- 4-10%
Risk Factors
• Young age: Increased risk of primary EBV infections in the early post transplant period
• Agents: Not any single agent more responsible but the cumulative intensity of immunosuppression seems to be most important.
Treatment• Decrease immunosuppression• Antivirals: acyclovir ganciclovir• Immunoglobulins: IVIG which helps to target
CMV• Chemotherapuetics: Rituximab (CD20 ligand)• Radiotherapy
Conclusions• PTLD is a rare complication of
transplantation- 2% of all solid organ transplant recipients
• More common in children secondary to primary exposure to EBV
• May present in the head and neck especially do to the rich lymphatic system
• Treatable as long as there is not monoclonal proliferation
R.G.
• Underwent treatment at a variety of levels• Immunosuppression was decreased• Given IVIG, Acyclovir, Ganciclovir• Started on Rituximab• Received radiation therapy treatments• Repeat MRI did eventually show regression
of disease
