Villous adenoma of the colon - Erler Zimmer 3D anatomy Series MP2071

This dissection model highlighting a villous adenoma of the colon is part of the exclusive Monash 3D anatomy series, a comprehensive series of human dissections reproduced with ultra-high resolution color 3D printing.

Clinical history

A 70-year-old man was admitted for findings of muscle weakness and passage of large amounts of mucus rectally. The patient was found to be hypokalemic. A sigmoid colon tumor was discovered and subsequently excised.

Pathology

A 15-cm-long segment of colon was opened longitudinally to show a large sessile tumor with a velvety surface. The tumor measures 11 x 7 cm. in diameter and is within 2 cm of the distal resection margin. The mucosa is otherwise normal. The serous surface is insignificant. Histological examination confirmed the presence of a villous adenoma.

Additional Information.

Villi adenomas occasionally secrete large amounts of protein ??mucoid and/or potassium-rich fluids, sufficient to cause hypoalbuminemia or hypokalemia. Villi adenoma is the least common but most threatening type of adenomatous polyp. Invasive carcinoma is present in up to 30% of cases at the time of resection.

What advantages does the Monash University anatomical dissection collection offer over plastic models or plastinated human specimens?

• Each body replica has been carefully created from selected patient X-ray data or human cadaver specimens selected by a highly trained team of anatomists at the Monash University Center for Human Anatomy Education to illustrate a range of clinically important areas of anatomy with a quality and fidelity that cannot be achieved with conventional anatomical models-this is real anatomy, not stylized anatomy.
• Each body replica has been rigorously checked by a team of highly trained anatomists at the Center for Human Anatomy Education, Monash University, to ensure the anatomical accuracy of the final product.
• The body replicas are not real human tissue and therefore not subject to any barriers of transportation, import, or use in educational facilities that do not hold an anatomy license. The Monash 3D Anatomy dissection series avoids these and other ethical issues that are raised when dealing with plastinated human remains.
