Mucinous cystic neoplasm of the gallbladder
Mucinous cystic neoplasms of the gallbladder are extremely rare epithelial cystic tumors formed by mucin-producing cells. They are histologically similar to the other mucinous cystic tumors found elsewhere in the body.
For the lesions involving the bile ducts, please refer to:
They are extremely rare tumors, which are more prevalent in middle-aged women 1,2.
Right upper quadrant pain is described as a common presentation 1.
These tumors are formed by columnar mucin-producing epithelial cells with an ovarian-like stroma 1,3.
The tumor, similarly to mucinous neoplasms elsewhere, are characterized by a cystic septated mass with anechoic content and possible low-level echoes 1.
Treatment and prognosis
Treatment is usually surgical resection.
