3D Printed Villous Adenoma of Colon
Clinical History
A 70-year old man was admitted for investigation of muscular weakness and the
passage of large amounts of mucus per rectum. The patient was found to be hypokalaemic. A tumour of sigmoid colon
was discovered and later resected.
Pathology
A 15 cm long segment of colon has been opened longitudinally to display a large sessile
tumour with a velvety surface. The tumour measures 11 x 7 cm. in diameter and approaches to within 2 cm of the
distal resection margin. The mucosa is otherwise normal. The serosal surface is unremarkable. Histological
examination confirmed the presence of a villous adenoma.
Further Information
Villous adenomas occasionally secrete large amounts of mucoid protein and/or
potassium rich fluid, sufficient to result in hypoalbuminaemia or hypokalaemia. Villous adenoma is the least common
but most ominous type of adenomatous polyp. Invasive carcinoma is present in up to 30% of cases at the time of
resection.

The models are very detailed and delicate. With normal production machines you cannot realize such details like shown in these models.
The printer used is a color-plastic printer. This is the most suitable printer for these models.
The plastic material is already the best and most suitable material for these prints. (The other option would be a kind of gypsum, but this is way more fragile. You even cannot get them out of the printer without breaking them).The huge advantage of the prints is that they are very realistic as the data is coming from real human specimen. Nothing is shaped or stylized.
The users have to handle these prints with utmost care. They are not made for touching or bending any thin nerves, arteries, vessels etc. The 3D printed models should sit on a table and just rotated at the table.
