Pararectal actinomycosis (actinomycosis paraproctitis) is characterized by the appearance of a dense immobile infiltrate in the tissue with relatively clear boundaries. The resulting infiltration spreads through the fiber, abscesses, forming a characteristic tuberosity that compresses the rectum, sometimes to complete obstruction. Opening of aristocort abscesses in actinomycosis occurs, as a rule, on the skin, extremely rarely - in the intestinal lumen. A slight swelling of the mucous membrane of the rectum is revealed, a symptom of pellotization is a protrusion of a dense infiltrate into the intestinal lumen, less often - bleeding of the mucous membrane. Patients note tenesmus, constipation. Fistulography reveals a network of anastomosing fistulous tracts in the adrectal tissue.

Primary actinomycosis of the gluteal region can develop at the site of a bruise, an injection of a medicinal substance. Actinomycosis of the sacral region comes, as a rule, from an epithelial coccygeal cyst. From pararectal or gluteal tissue, actinomycosis can spread to the perineum, urinary-genital organs. Actinomycosis of the urinary-genital organs.
