Clinical presentation

A 64 year old woman with a history of Bentall operation and maintenance haemodialysis due to multiple myeloma presented with a positive faecal occult blood test. She denied abdominal symptoms. Physical examination was unremarkable. Leucocytosis was absent. Colonoscopy showed a globular submucosal tumour with the appendiceal orifice (arrow) on its top (fig 1). Computed tomography demonstrated a cystic lesion with “eggshell”-like mural calcification (arrow) in the expected region of the appendix (fig 2).
