Adrenocortical carcinoma presenting with a peritoneal effusion.

In this report, we describe the fine-needle aspiration findings of a case of adrenocortical carcinoma (ACC) that spread to the peritoneal cavity in an 80-year-old female. Cytologically, the peritoneal fluid exhibited clusters and single, small uniform cells with round nuclei and a fine chromatin pattern, which in conjunction with the immunohistochemical stains was diagnostic of ACC. Although ACC is the most common malignant neoplasm of the adrenal gland, its metastatic spread to the peritoneal cavity is exceptionally unusual.

Extranodal lymphomas: review of clinicopathologic and cytologic features.

Extranodal lymphomas can be challenging for a practicing cytopathologist, especially in the fine needle aspiration clinic setting. These lymphomas can vary in type from one extranodal site to another. A variety of these lymphomas have very specific clinicopathologic features.
