History

The clinical features of lymphomatoid granulomatosis reflect systemic multiorgan disease. Pulmonary involvement usually is present, while the skin (50%), nervous system (25%), kidneys, and liver are affected less commonly. The lymph nodes, spleen, and bone marrow usually are spared until late in the course of illness. Araki et al reported primary orbital involvement. [3]

  • Pulmonary involvement
    • Cough and dyspnea are present in most patients.
    • Sputum production may reflect associated pneumonia.
    • Hemoptysis usually indicates disease cavitation.
  • Systemic presentation of lymphoma-related B symptoms: Patients may have fever, weight loss, and malaise.
  • Skin
    • Patchy, occasionally painful, erythematous macules, papules, and plaques typically involve the gluteal regions and extremities. [4]
    • Erythema may involve nodosumlike subcutaneous nodules that may ulcerate but are often truncal.
    • Isolated cutaneous lymphomatoid granulomatosis has been reported.
  • Nervous system
    • Extensive lymphocytic infiltration of the meninges, cerebral vessels, and peripheral nerves is found in as many as 25% of patients.
    • CNS may include mass lesions. Neurological manifestations, including mental status changes, ataxia, hemiparesis, and seizures, may occur.
    • Peripheral nerve involvement may include distal sensory neuropathy or mononeuritis multiplex.
    • Isolated neurological lymphomatoid granulomatosis has been reported. [5, 6]
  • Renal
    • Clinically significant renal disease is uncommon.
    • At autopsy, renal involvement is present in 45% of cases.
    • Unlike WG, glomerulonephritis is not a feature of lymphomatoid granulomatosis.
  • Liver
    • Hepatic involvement also is frequent at autopsy (29% of cases), but clinical disease is rare.
    • Hepatomegaly is present in 12% of cases and may carry a worse prognosis.

Causes

Other than its association with opportunistic disease and EBV, the etiology of lymphomatoid granulomatosis is unknown.
