Abstract

Increased risk of haematological malignancies has been described in Gaucher disease patients; however, high-grade lymphoma has been rarely observed. We report two patients with Gaucher disease and sicca syndrome diagnosed with aggressive lymphoma involving the parotid gland. A 29-year-old woman with Gaucher disease developed tumour of the left parotid gland. She reported chronic arthralgias, xerostomia and xerophthalmia. Parotid gland biopsy disclosed diffuse large B-cell lymphoma. No lymphadenopathy was found. Bone biopsy revealed focal lymphomatous infiltration consistent with stage IV disease. MACOP-B chemotherapy regimen (cyclophosphamide, adriamycin, methotrexate, bleomycin, vincristine, prednisone) resulted in complete remission for 15 years. A 76-year-old patient with Gaucher disease suffered from dry-mouth feeling. He developed a left parotid gland tumour. CT scan disclosed diffuse lymphadenopathy, pleural effusion and multiple lung nodules. A cervical lymph node biopsy revealed mantle cell lymphoma. Fine-needle aspiration of the parotid gland showed lymphoma cells. Immunochemotherapy with fludarabine, cyclophosphamide and rituximab resulted in complete remission. Accumulation of the glucocerebroside in Gaucher disease activates macrophages, inducing release of pro-inflammatory cytokines which may be involved in the pathogenesis of second malignancy. Patients with Gaucher disease bear an increased risk of haematological malignancies; however, aggressive lymphoma has been described only occasionally. In both our patients the presenting sign of lymphoma was tumour of the parotid gland. The patients suffered from sicca syndrome, which increases risk for developing lymphoma. The underlying Gaucher disease and sicca syndrome might be implicated as immunological triggers for lymphoma occurrence and its propensity for the parotid gland in these patients.
