Mucosal lymphoid aggregates normally display a distinct absence of pigment producing a “starry sky” appearance, especially in the rectosigmoid region. Interestingly, some focal, usually sessile, colonic mucosal neoplastic lesions, rather than submucosal lesions, may be better appreciated as pigment deposition may be absent or limited.
