“…However, epithelial cells of the MCN produce mucus, which is the main component. From the viewpoint of immunohistochemistry of the core protein of mucin, the meaning of a specific profile of mucin expression (eg, MUC1) is controversial in MCN of the liver [ 20 ], although this expression reflects the malignant potential of cystic, mucus-producing neoplasms of the pancreas [ 21 ].…”

Patient: Male, 70-year-old Final Diagnosis: Liver disease Symptoms: Asymptomatic Medication:— Clinical Procedure: Hepatectomy Specialty: Gastroenterology and Hepatology Objective: Rare disease Background: Mucinous cystic neoplasm (MCN) of the liver is a rare hepatic neoplasm: a cystic, mucus-producing tumor. Histopathologic examination reveals ovarian-like stroma. The origin of MCN of the liver is still unknown, although ectopic ovarian-like stroma in the liver has been suggested as a possibility. We document a thought-provoking case of MCN of the liver, and intratumoral fatty tissue may support the opinion that ectopic ovarian-like stroma in the liver is a possible origin for both MCN and ovarian teratoma. Case Report: An expansive 10.5-cm cystic tumor was incidentally detected in a 71-year-old woman. Imaging studies revealed that the tumor was multiloculated, with cyst contents comprising mucus, muddy-looking fluid (inspissated bile), and hematoma. Imaging studies revealed fatty tissue and calcifications in the cyst walls. The diagnosis of MCN of the liver was made, although MCNs have never been reported to include fatty tissue. Extended left lobectomy was performed, and the tumor was curatively removed without any rupture. A multilocular cyst, mucus, calcifications, and fatty tissue were clearly observed on gross inspection. Histopathological examination revealed ovarian-like stroma. Evidence of malignancy was not detected. Her postoperative course was uneventful. To the best of our knowledge, our patient is the first case of MCN of the liver with intratumoral fatty tissue. This case may support the hypothesis that MCN originates from ectopic ovarian-like stroma in the liver. Conclusions: We documented a thought-provoking case of MCN of the liver in detail, and this MCN accompanied with fatty tissue might originate from ectopic ovarian-like stroma.

“…The epithelial cells of the gonads migrate from the posterior wall of the yolk sac to the surface of nearby organs along the wall of the hindgut[ 2 ]. It is important to consider that MCN-L can progress to invasive carcinoma, although its degree of malignancy is less than that of primary liver cancer[ 13 ].…”

BACKGROUND Mucinous cystic neoplasm of the liver (MCN-L) is a cyst-forming epithelial neoplasm. The most distinguishing feature is the ovarian-type subepithelial stroma on pathological examination. CASE SUMMARY An abdominal ultrasound incidentally revealed a liver tumor in a 32-year-old woman. Physical and laboratory examination results did not reveal any abnormalities. Enhanced abdominal computed tomography (CT) revealed a cystic space measuring 7.2 cm × 5.4 cm in the liver. Subsequent CT showed an increase in tumor size. Thus, we performed surgical resection of the tumor and gallbladder. Postoperative histopathological examination confirmed the diagnosis of MCN-L. At the 6-mo of follow-up, no recurrence was observed on ultrasound or CT. CONCLUSION Since preoperative diagnosis of MCN-L is difficult, active surgery is recommended and helpful for the diagnosis and treatment of MCN-L.
