Anal pain and bloody stools are clinically common signs that are often treated initially as hemorrhoids or anal abscesses. Anal abscesses, a rare manifestation of rectal cancer, can easily mislead the identification and delay the diagnosis of rectal cancer. In this case, a 66-year-old man mistakenly believed that his long-term anal pain was caused by anal abscesses and ignored symptoms of bloody stools, lower abdominal pain, and changes in stool form. He did not seek medical treatment until he had a pale complexion, mental weakness, and severe discharge from the hip masses. The clinical diagnosis of rectal adenocarcinoma complicated by perianal soft tissue invasion was gradually established through a digital anal examination, laboratory tests, a pathological examination, and computed tomography. After preoperative adjuvant therapy, tumor resection was performed. The disease was well controlled, and the patient was followed up through outpatient visits. Clinical practitioners may encounter patients with various disease conditions. For cases of anal abscesses complicated by hip abscesses, clinicians should gradually analyze the disease course by collecting detailed information, confirming the rectal wall thickness and abscess invasion scope on imaging, and pay attention to the importance of pathological examination to prevent missing the possibility of rectal cancer complicated by anal abscesses. |
