Abstract:
Heterotopic bone formation is a very rare event in the gastrointestinal tract including in the appendix.
Here we report three cases of heterotopic ossification in appendiceal mucinous neoplasms, one
occurring in an appendiceal mucinous cystadenoma, another in a low-grade appendiceal mucinous
neoplasm, and the third occurring in an appendiceal mucinous adenocarcinoma. The clinicopathologic
characteristics of these three present cases and two previously reported cases are discussed in detail.
The mechanism of heterotopic ossification in appendiceal mucinous neoplasm is still unclear, but
mucin extravasation and subsequent calcification may be predisposing events.
