Pcolor: Draw a square around (highlight) a single pixel

I would like to draw a square around a single pixel to emphasize it. I envision something like the default grid of pcolor, but only around a single pixel. Is this possible, or are there other ways to draw the eye to a single position on a pcolor grid?

You might try this:
Otherwise, just write into the columns and rows like you'd expect
yourImage(row-1:row+1, column - 1) = 255; % Left edge
yourImage(row-1:row+1, column + 1) = 255; % Right edge
yourImage(row-1, column) = 255; % Top edge
yourImage(row+1, column) = 255; % Bottom edge

You can use plot() or line() to plot lines in the overlay above the image.
