Polypoid mucosal prolapse complicating low rectal adenomas: beware the inflammatory cloacogenic polyp!

abstract：:Fine needle aspiration (FNA) cytology is a valuable aid to diagnosis and tumour staging in patients with non-Hodgkin's lymphoma. These tumours are often multicentric and involve sites such as the liver or the spleen which are not easily accessible to surgical biopsy. Particularly with splenic involvement, there is a d...
