Background Historically, sampling of adrenal lesions has been performed by percutaneous image‐guided fine‐needle aspiration (FNA) biopsy. Endoscopic ultrasound guided (EUS)‐FNA of the adrenals was first employed at Cleveland Clinic ~10 years ago. We report a two‐decade experience of adrenal FNA in our institution. Methods An electronic retrieval identified adrenal FNAs from 1997 to 2017. Data points from each case (diagnosis, method of FNA, age, sex, laterality, needle gauge, size of lesion, adequacy of sample, and histologic follow up) were analyzed. Results Our retrieval confirmed 198 adrenal FNAs performed over 20 years. Of these, 90% (179/198) were percutaneous, and the remaining 10% (19/198) were collected by EUS. Of the 179 CT guided FNAs, 93% (162/179) yielded an adequate specimen as compared with an adequacy rate of 89% (17/19) for EUS‐FNAs, with no significant difference in adequacy rates by collection method, P = .64 (Fisher's exact). Of all adrenal FNAs, 53% (105/198) confirmed metastases, 33% (65/198) showed adrenal cells or primary adrenal neoplasms (85% cortical cells, 14% cortical neoplasia, 1% pheochromocytoma), 8% were inadequate (15/198), 3% were atypical (7/198), and 2% were suspicious for malignancy (5/198). Conclusion FNA of the adrenal glands can be useful in the diagnosis and staging of metastatic neoplasms, as well as in distinguishing primary adrenal cortical from medullary neoplasms and characterizing hematolymphoid and mesenchymal neoplasms. Overall adequacy rates for adrenal cytology are high (92%) with no statistically significant difference between CT‐guided (93%) and EUS‐FNA adequacy (89%). The majority of our procedures confirmed metastases, sparing patients unnecessary surgery.

Calciphylaxis is a serious medical condition that is typically associated with end-stage renal disease and presents as the sequelae of calcifications in arterioles with subsequent ischemia of affected tissues. Classically, calciphylaxis produces ulcerated and necrotic skin lesions. These may be biopsied to aid in confirmation of the diagnosis. Herein we report a case of a large necrotic breast lesion in the clinical setting of calciphylaxis, and we emphasize that a multidisciplinary approach to diagnosis and management is important to avoid unnecessary oncological resection.

Background: Tumors of the pancreas are often primary in nature, but are occasionally proven to be secondary. We report a 12-year review of all pancreatic tumors shown to be metastatic at the University of Colorado. Method:The electronic pathology database was searched between 2008 and 2020, for all pancreatic fine-needle aspiration cases at the University of Colorado to identify and review metastatic tumors to the pancreas. Additional data points to include age, sex, radiographic features, and clinical management were analyzed.
