Why should cysts associated with cystadenoma or cystadenocarcinoma not be biopsied?

Cysts associated with cystadenoma or cystadenocarcinoma should not be biopsied primarily to avoid the risk of rupture, which can lead to pseudomyxoma peritonei. Pseudomyxoma peritonei is a serious condition characterized by the accumulation of mucinous material in the abdominal cavity due to the leakage of mucin from a ruptured cyst or tumor. If a biopsy is performed on these cysts, the procedure can inadvertently cause the cyst to rupture, releasing its contents into the peritoneal cavity and initiating this harmful process. Given the potential for serious complications, such as pseudomyxoma peritonei, it is crucial to take a careful approach in managing cystadenomas and cystadenocarcinomas.

The other options, while they may present concerns in different clinical contexts, do not encapsulate the primary reason for avoiding a biopsy of these cysts. For example, the size of the cysts (too small for biopsy) is not a definitive factor, as cystadenomas and cystadenocarcinomas may vary significantly in size. The risk of infection, while a consideration in many procedures, is not the main concern in this scenario. Additionally, the potential lack of diagnostic value does
