Medical records were reviewed and results of EUS, cytology, adrenal size change on follow-up imag-ing ≥ 6 mo after EUS and any repeat EUS or surgery were abstracted. A lesion was considered benign if： （1） EUS-FNA cytology was benign and the lesion remained 〈 1 cm from its original size on follow-up computed tomography （CT）, magnetic resonance imaging or repeat EUS ≥ 6 mo after EUS-FNA; or （2） subsequent adrenalectomy and surgical pathology was benign. RESULTS： Ninety-four patients had left （n = 90） and/or right （n = 5） adrenal EUS-FNA without adverse events. EUS indications included： cancer staging or suspected recurrence （n = 31）, pancreatic （n = 20）, medi-astinal （n = 10）, adrenal （n = 7）, lung （n = 7） mass or other indication （n = 19）. Diagnoses after adrenal EUS-FNA included metastatic lung （n = 10）, esophageal （n= 5）, colon （n = 2）, or other cancer （n = 8）; benign primary adrenal mass or benign tissue （n = 60）; or was non-diagnostic （n = 9）. Available follow-up confrmed a benign lesion in 5/9 non-diagnostic aspirates and 32/60 benign aspirates. Four of the 60 benign aspirates were later confrmed as malignant by repeat biopsy, follow-up CT, or adrenalectomy. Adrenal EUS-FNA diagnosed metastatic cancer in 24, and ruled out metastasis in 10 patients. For the diagnosis of malignancy, EUS-FNA of either adrenal had sensitivity, specifcity, positive predic-tive value and negative predictive value of 86%, 97%, 96% and 89%, respectively.CONCLUSION： Adrenal gland EUS-FNA is safe, mini-mally invasive and a sensitive technique with signifcant impact in the management of adrenal gland mass or enlargement.展开更多

A 79-year-old female presented in the emergency room with epigastric discomfort, and an immovable mass was palpated in her abdomen upon physical examination. Imaging studies revealed a large cystic lesion in the pancreatic tail. The radiologic impression ruled out the possibility of a mucinous cystic neoplasm, or a pseudocyst in the pancreas. The operative findings demonstrated that the cystic mass originated in the left adrenal gland. A laparoscopic excision of the cystic mass was performed, and immunohistochemistry confirmed that this mass was a lymphangioma of the adrenal gland. Several prior reports have suggested that lymphangioma can mimic renal or splenic cysts. However, lymphangioma cases mimicking pancreatic cysts are very rare.展开更多

We here report another case of myxoid adenoma of the adrenal gland in a 45-year-old Chinese man who was admitted to hospital because of the right adrenal mass and mild hypertension. At surgery, the mass was well-circumscribed, measured 3.3 cm in diameter. Light-microscopic findings showed most of the tumor region with myxoid stroma, and the tumor cells were benign-look- ing. Immunohistochemical study showed the tumor had the positivity for vimentin, synaptophysin, neuron specific endolase but negative with cytokeratin and epithelial membrane antigen. Moreover, it was negative with alpha-inhibin that is not in accordance with those reported. There was no finding corresponding to malignancy.展开更多

We present an unusual case of uterine cancer metastasizing to the adrenal glands with a review of the English literature on the management of this rare disease. CASE SUMMARY A 53-year-old Caucasian woman with a history of endometrial cancer (grade 2;International Federation of Gynecology and Obstetrics III A) was hospitalized in November 2017 for a left adrenal mass found on a follow-up computed tomography scan 3 years after her gynecological surgery. Laboratory test results were normal. A laparoscopic left adrenalectomy was performed. The postoperative course was uneventful, and no chemotherapy was administered. The pathological report confirmed an adrenal endometrioid metastasis. At 36 mo of follow-up, the patient is alive and well, with no evidence of recurrent disease. A literature review identified only 11 previously-published cases of adrenal metastases from uterine cancer. CONCLUSION Adrenal metastasis from uterine cancer is very rare. Laparoscopic adrenalectomy may be an effective treatment in selected cases of localized adrenal metastasis.展开更多
