RESUMO
Mucinous cystadenomas are a common benign neoplasm of the ovaries that can grow much larger than other adnexal masses; they are recognized as precursors of ovarian cancer and may slowly transform to borderline tumors and invasive ovarian cancer. Prompt and accurate treatment is essential as these tumors can grow to massive sizes and be potentially lethal if left untreated. Health care providers must understand the patient, their expectations and their problems; without proper communication and follow-up, any treatment is destined to disappoint. We present a case of a 76-year-old female with limited access to health care. She presented with a giant cystadenoma that grew over 1 year. Complete resection was decided and the patient underwent complete recovery. On follow-up control patient is doing well.
