Neuroendocrine tumors (NETs) arise from neuroendocrine cells, which produce hormones and are found throughout the body-most commonly in the gastrointestinal tract, pancreas, and lungs. NETs can be slow-growing or more aggressive. Some secrete excess hormones, leading to distinct clinical syndromes. Early detection and proper characterization guide the best treatment approach.
NET symptoms vary depending on tumor location and hormonal activity. Many small NETs cause no signs at first. As they grow or secrete hormones, you may notice:
The exact origins of many NETs remain unclear, but known risk factors include:

A perianal fistula is a small tunnel that forms between the anal canal and the skin near the anus, often developing after an infection or abscess and potentially causing pain, swelling, or drainage if left untreated.
Most perianal fistulas begin when an anal gland becomes blocked and infected; additional factors include inflammatory bowel diseases like Crohn's, prior injury or surgery, and, less commonly, infections such as tuberculosis.
It typically appears as a small red bump or opening near the anus that may leak pus or blood, accompanied by redness, itching, or irritation around the area.
A seton is a medical thread or rubber band placed through the fistula tract to maintain drainage, prevent premature closure, and allow the tunnel to heal gradually.
Most patients experience full healing within four to six weeks following fistula surgery, though complex cases may require a longer recovery period.
While many perianal fistulas require surgical intervention to heal completely, some mild cases or those related to inflammatory bowel disease may respond to medications alone.
Consult a physician if you notice persistent pain, swelling, drainage, or a recurring abscess near the anus, or if you experience fever or difficulty sitting.
A physical examination is often sufficient, but imaging studies such as MRI or endoanal ultrasound may be used to map complex fistula tracts before treatment.
Postoperative care includes regular sitz baths, keeping the area clean and dry, following wound care instructions, resting as advised, and attending follow-up visits to ensure proper healing.
