Staging for CLL-type non-Hodgkin's lymphoma reveals a gastrointestinal stromal tumour.
We report a 73-year-old man presenting with fatigue, lymphadenopathy and weight loss. He had no abdominal pain, fever or night sweats. Physical examination revealed a palpable 1.4-cm hard nontender lymph node behind the left sternocleidomastoid muscle and a palpable 2-cm lymph node in the left axilla. Bone marrow examination and excisional biopsy of the lymph node behind the left sterno-cleidomastoid muscle showed a CLL-type non-Hodgkin's lymphoma (CLL-type NHL). Staging by CT scanning revealed, besides axillary and mediastinal adenopathy, an unexpected mass in the stomach. Gastroscopy and pathological evaluation showed a gastrointestinal stromal tumour (GIST) with immunohistochemical staining for CD 34 and CD 117. The patient was treated with imatinib. CLL-type NHL and GIST both tend to occur in middle-aged and older patients. A double-tumour consisting of both these tumours is rare: the incidence is estimated to be 3 per 10 billion people.
