The contour of the abdomen describes the patient's nutritional state and normally ranges from flat to rounded. Abnormal contours are described as scaphoid and protuberant. A scaphoid abdomen has a concave symmetrical profile which reflects a decrease in fat deposits, a malnourished state, or flaccid muscle tone. A convex symmetrical profile, with maximum height of the abdomen at the umbilicus is a protuberant abdomen. A convex contour with taut stretching of skin over the abdominal wall refers to abdominal distention. An asymmetrical profile, possibly indicating the presence of a tumor or a bowel obstruction, is a description of the symmetry of the abdomen, not the contour.
