3D Printed Multiple Polyposis Coli
Clinical History
There are no details of the clinical history.
Pathology
The specimens from this case consists of two segments of sigmoid colon. The mucosa of
the bowel is studded with numerous sessile and pedunculated partially pigmented polyps up to 1.5 cm in maximum
diameter. There is no macroscopic evidence of malignant change.
Note
Microscopically, the polyps are most commonly tubular adenomas (>75% have a tubular
structure; also called adenomatous polyps). Less frequently, they are villous adenomas (>75% have villous
morphology) or tubulovillous adenomas (25-75% villous). They can have varying grades of dysplasia. The histological
appearances are identical to sporadic colonic adenomas.
Patients with familial adenomatous polyposis (FAP; a form
of hereditary colon cancer syndrome involving the APC gene located on chromosome 5q21) are offered prophylactic
colectomy because invasive adenocarcinoma is almost certain to develop in one or more of the polyps, usually about
15 years after the onset of the adenomatosis. This condition is transmitted as an autosomal dominant trait.

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.
