Myxoglobulosis, A Rare Variant of Appendiceal Mucocele: Case Report and Review of the Literature

Introduction: Appendiceal mucocele is a term referring to the abnormal accumulation of mucus into the lumen of appendix regardless of the underlying cause. Mucocele alone is not considered a rare finding in routine appendectomy. However, the coexistence of multiple small intraluminal globoid bodies as “myxoglobulosis” or “caviar appendix” is a rare finding. Case report: We report a 54 year old woman with complaint of abdominal pain who subequnetly had a surgery with the final diagnosis of peritonitis due to perforated peptic ulcer. During the operation, a jejunal mass and appendiceal dilation were observed incidentally. By histopathologic examination, a diagnosis of submucosal leiomyoma for jejunal mass, nonspecific ulceration for peptic specimen and cystadenoma with myxoglobulosis for appendix specimen was made. She had an uneventful postoperative course and after five months, she reported that she had not experienced any discomfort or pain. Conclusion: this report presents a rare case of appendiceal myxoglobulosis secondary to mucinous cystadenoma, which was incidentally found in patient with peritonitis due to peptic ulcer disease.
