Anal marisca are small masses located at the anal margin, near the anus
, the end of the gastro-intestinal tract. The marisca is generally soft and painless on palpation. Anal marisca appear almost exclusively due to external hemorrhoids
, which are a dilation of the veins
of the anus. In general, external hemorrhoids disappear spontaneously after a few days of evolution, but they can leave a type of scar, which is the marisca. Anal marisca present no health hazard and usually cause no pain
, it is not necessary to treat them. In rare cases, however, mainly for large marisca, they can be responsible for discomfort or itching, in which case they can be removed surgically.
