BACKGROUND: Primary @entity1575 is a rare @entity5 that originates in the submesothelial tissue of the liver and is frequently misdiagnosed because of its rarity and unfamiliar characteristics. AIM: To analyze, summarize and update the clinical and pathological features of primary @entity1575 . METHODS: We systematically extract the clinical data of 4 cases from the relevant medical records, analyze the macroscopic, histological and immunohistochemical features and review the 59 previously reported cases in the English literatures. RESULTS: The @entity1 ' mean age 50.75 years (range, 49-52 years), and the gender ratio was 1:1. The @entity5 ranged in size from 2.3 to 12.0cm (average diameter, 7.85cm). The @entity5 were composed of spindle cells with oval, fusiform or banded nuclei that were arranged in bundled, storiform or peculiar random patterns. Mitosis and @entity2698 -like vessels were occasionally observed. Immunohistochemically, three cases were positive for Signal transduction and activator of transcription 6, cluster of differentiation 34, @entity1892 and vimentin but were negative for nervous, muscular and hepatocellular markers. Hepatic lobectomy was performed in all cases, and one @entity1 received adjuvant chemotherapy simultaneously. One @entity1 suffered two recurrences without @entity3 , and the remaining @entity1 experienced favorable outcomes. CONCLUSIONS: A consensus on the essential and definite diagnostic criteria for primary @entity1575 must be reached in a timely manner. Signal transduction and activator of transcription 6 is a highly sensitive and specific immunohistochemical marker for primary @entity1575 .

An update on primary XXXX : An examination of the clinical and pathological features of four case studies and a literature review.
