History
This woman presented at the age of 65 with a lump in her abdomen which she had felt
herself. She had had 2 months episodic diarrhoea before this. The resected tissue comes from the
transverse colon; enlarged lymph nodes were found in the mesocolon. Histologically the lesion is
a poorly-differentiated lymphocytic lymphoma.
