Atypical variant takotsubo cardiomyopathy secondary to pheochromocytoma.

A 39-year-old woman presented with chest pain and elevated troponin levels. Cardiac catheterization demonstrated no coronary artery disease, with findings consistent with atypical variant takotsubo cardiomyopathy. Further workup showed elevated plasma fractionated metanephrines suggestive of pheochromocytoma.

Adrenocortical carcinoma arising from the colonic mesentery.

A 57-year-old woman presented with left-sided abdominal pain and was found to have a large retroperitoneal mass in the left upper quadrant. Surgical excision and histopathologic evaluation demonstrated an adrenocortical carcinoma arising from the colonic mesentery. Ectopic adrenocortical carcinomas are extremely rare tumors with an unknown incidence.

Unusual appearance of malignant peritoneal mesothelioma.

Malignant peritoneal mesothelioma (MPM) is a rare and fatal cancer arising from the mesothelial cells lining the peritoneum. This typically occurs in men in their fifth and sixth decades, but can be seen in women and any age group. Pleural and extrapleural mesothelioma can arise in the setting of asbestos exposure, but other reported causes of MPM include exposure to silicate fibers and radiation therapy.
