WHO classification:
Early (reactive plasmacytic hyperplasia)
Polymorphic PTLD
Monomorphic PTLD (lymphomas)
PTLD
Post-Transplant Lymphoproliferative Disorder
•
Related to degree and duration of immunosuppression, type of
organ transplanted, CMV status
•
Fever, adenopathy
•
Extranodal disease in >2/3 of cases (muscle involvement
extremely rare)
•
Excisional biopsy, multiple core needle biopsies, bone marrow
biopsy, CT chest/abd/pelvis
•
Rx: Reduction of immunosuppression, antiviral, anti-B-lymphocyte
antibodies (rituximab), interferon, chemotherapy
•
Reported rates of cure/survival variable because of heterogeneity
of disease
PTLD
•
Differential: Smooth muscle
neoplasms (leiomyoma,
leiomyosarcoma) increased incidence
in immunocompromised

Differential diagnosis
Pyomyositis
Necrotizing fasciitis
Ischemia
Polymyositis
Scleroderma
Nephrogenic systemic sclerosis
Nephrogenic Systemic Sclerosis
(Nephrogenic Fibrosing Dermopathy)
•
Rare multisystemic disorder in patients with renal insufficiency
first described in 1997 (200 cases reported to ICNFDR)
•
Unknown etiology
•
IV gadolinium may serve as a trigger in the setting of acute
hepatorenal syndrome or dialysis-dependent chronic renal
insufficiency
•
Skin induration of extremities and trunk
•
Myalgia, weakness
•
Skin biopsy: proliferation of fibroblasts adjacent to collagen
bundles and absence of inflammatory cells
Nephrogenic Systemic Sclerosis
(Nephrogenic Fibrosing Dermopathy)
•
Systemic fibrosis with involvement of the
skeletal muscle, bone, pleura, pericardium,
myocardium, kidney, testes, dura
•
•
•
At LLUMC 12 patients 2000-2006
Skin fibrosis and joint contractures within 211 weeks following double-dose iv
gadodiamide
AJR 2007: 188, February 2007
Nephrogenic Systemic Sclerosis
(Nephrogenic Fibrosing Dermopathy)
Nephrogenic Systemic Sclerosis
Neprogenic Systemic Sclerosis
•
Long term outcome: Severe inability to ambulate due to
contractures and myopathy, cane required for ambulation, no
disability. Skin changes persist.
•
Plasmapheresis may have some effect. Dialysis probably of
no help.
•
FDA issued a public health advisory in June 2006 with
regards to high-dose gadolinium-containing agents in patients
with renal failure
•
At LLUMC: no iv gadodiamide in acute renal failure,
hepatorenal syndrome, dialysis patients or ESRD with
creatinine clearance of <15 ml/min, no double/triple dose
Neprogenic Systemic Sclerosis
•
Screen patients with serum creatinine
and calculated creatinine clearance
prior to MRI with contrast if history of
kidney disease, diabetes, or >60 y.o
