Cronkhite-Canada syndrome associated with perianal condyloma acuminatum with malignant transformation: A case report.

RATIONALE: Cronkhite-Canada syndrome (CCS) is a rare non-familial polyposis syndrome characterized by multiple gastrointestinal polyps with the ectodermal triad. To date, many complications of CCS have been reported in the literature, but perianal condyloma acuminatum with malignant transformation has not been included. PATIENT CONCERNS: This report presents the case of a 52-year-old Chinese man who presented with diarrhea, loss of appetite, and weight loss. He developed skin pigmentation and atrophy of the fingernails and toenails. Upper gastrointestinal endoscopy, colonoscopy, capsule endoscopy, and enteroscopy revealed diffuse polyps along the entire digestive tract. Histopathological examination revealed polyps of different pathological types dominated by hamartoma. Physical examination revealed a crissum cauliflower-like neoplasm (2.5 × 2.0 cm). After perianal tumor resection, pathology suggested that this was a perianal condylomatous lesion with malignant transformation, as well as well-differentiated squamous cell carcinoma. DIAGNOSES: These clinical features and endoscopic findings were consistent with CCS which associated with perianal condyloma acuminatum with malignant transformation. INTERVENTION: Clinical remission was achieved with glucocorticoid, azathioprine, and nutritional support. OUTCOME: At the 4-year follow-up, the patient had no diarrhea or loss of appetite, had gained 13 kg in weight, and the perianal tumor had not recurred. LESSONS: No previous report has described CCS in a patient with perianal condyloma acuminatum with malignant transformation. As both conditions are related to immune disorders, their occurrence may be correlated.

Delayed bowel obstruction after seat belt injury: a case report.

BACKGROUND: Delayed bowel obstruction due to seat belt injury is extremely rare. The delayed onset of nonspecific symptoms makes a timely diagnosis difficult. A deep understanding of the characteristics of this condition is helpful for early diagnosis and treatment. CASE PRESENTATION: A 39-year-old male was transferred to our hospital from another hospital complaints of progressive abdominal distension and severe weakness. In the previous hospital, he was diagnosed with "adult megacolon" and was recommended for surgical treatment. In our hospital, he was diagnosed with delayed bowel obstruction due to seat belt injury and underwent surgical intervention. Following laparoscopic adhesiolysis and resection of the narrow small intestine, his symptoms improved rapidly, and he was discharged. CONCLUSION: Delayed bowel obstruction due to seat belt injury may present clinical symptoms any time after the injury. Imaging examination, ileus tube and small colonoscopy may provide us with valuable cues for the diagnosis and treatment of delayed bowel obstruction, and laparoscopy may be an alternative approach in surgical intervention.
