In the last few years, a recently described neoplasm designated as gastroblastoma has emerged.
The Table lists the immunohistochemical findings of the current case as well as those of the previously reported cases of gastroblastoma.
Gastroblastoma has been compared to other blastomas, such as pleuropulmonary blastoma, hepatoblastoma, and nephroblastoma.
Diagnosing gastroblastoma on a biopsy specimen is probably impossible, because of its different histologic features.
In summary, gastroblastoma is a recently described, biphasic neoplasm of the stomach.
A distinctive novel epitheliome-senchymal biphasic tumor of the stomach in young adults ("gastroblastoma"): a series of 3 cases.
Novel epitheliomesenchymal biphasic stomach tumor (gastroblastoma) in a 9-year-old: morphological, ultrastructural and immunohistochemical findings.
