We report the clinicopathologic, immunophenotypic, DNA ploidy, and MIB-1 proliferative findings of five adenomatoid tumors of the adrenal gland. All patients were male, and tumors were incidental radiologic, surgical, or autopsy findings. Mean patient age at diagnosis was 41 years (range 31–64 years

Adenomatoid tumor of the adrenal gland: A clinicopathologic study of five cases and review of the literature

Thread-like bridging strands: a morphologic feature present in all adenomatoid tumors.

We report a case of an adenomatoid tumor involving the heart. The lesion was found incidentally at the time of cardiac surgery, measured 1.0 cm, and was poorly demarcated from the adjacent myocardium. Microscopically, the tumor consisted of aggregates of relatively large, epithelioid cells that coalesced to form tubular spaces and occasionally branched into anastomosing channels. The neoplastic cells were strongly immunoreactive with antibodies against cytokeratin. The pathologic features of this unusual cardiac tumor are diagnostic of an adenomatoid tumor, a relatively rare benign neoplasm of mesothelial origin usually found in association with the genital tract. Although rare cases of adenomatoid tumors found outside of the genital tract have been described, including two recently reported pleural tumors, it has not been described to involve the heart.

Adenomatoid tumor of the heart : Report of a case

The aim of this case report is to describe the appearance on magnetic resonance imaging (MRI) of an incidentally found adenomatoid tumor of the adrenal gland, and to evaluate the utility of MRI in characterizing this type of tumor. The appearance of the tumor was nonspecific on T1-weighted in-phase, opposed-phase, and T2-weighted images, as well as its behavior after paramagnetic contrast administration, outlining the differential diagnosis among carcinoma, metastatic tumors, and pheochromocytoma. After surgery, the pathologic diagnosis was adenomatoid benign tumor of mesothelial origin. Although MRI enables the characterization of most benign lesions of the adrenal gland, the appearance of other lesions is nonspecific. In our case, MRI did not assist in preoperative diagnosis, guiding us towards a diagnosis of malignancy.
