Synchronous Intercostal Nerve Schwannomas: A Rare Cause of Chest Wall Pain.

Schwannomas are nerve sheath tumors arising from Schwann cells. Schwannomas of the intercostal nerve are extremely rare, with limited published literature. These tumors are generally regarded as benign asymptomatic.

3D printing anatomical models of head bones.

Purpose: In many medical schools, the study of Anatomy is becoming increasingly theoretical owing to the difficulty of having human body parts available, rather than offering the students the possibility of a more realistic and practical approach. We developed a project where we use a 3D printer to produce models of the human skull bones, with high quality and quantity to satisfy the needs for Anatomy classes and to be available for request to study at home.

Methods: We selected regular and well-shaped bones of the head upon which we based the 3D models.
