SummaryThe objective of this study is to report three cases of paraneoplastic or ectopic Cushing syndrome, which is a rare phenomenon of the adrenocorticotropic hormone (ACTH)-dependent Cushing syndrome. Three cases are reported in respect of clinical presentation, diagnosis and treatment in addition to relevant literature review. The results showed that ectopic ACTH secretion can be associated with different types of neoplasm most common of which are bronchial carcinoid tumors, which are slow-growing, well-differentiated neoplasms with a favorable prognosis and small-cell lung cancer, which are poorly differentiated tumors with a poor outcome. The latter is present in two out of three cases and in the remaining one, primary tumor could not be localized, representing a small fraction of patients with paraneoplastic Cushing. Diagnosis is established in the setting of high clinical suspicion by documenting an elevated cortisol level, ACTH and doing dexamethasone suppression test. Treatment options include management of the primary tumor by surgery and chemotherapy and treating Cushing syndrome. Prognosis is poor in SCLC. We concluded that in front of a high clinical suspicion, ectopic Cushing syndrome diagnosis should be considered, and identification of the primary tumor is essential.Learning points:Learning how to suspect ectopic Cushing syndrome and confirm it among all the causes of excess cortisol.Distinguish between occult and severe ectopic Cushing syndrome and etiology.Providing the adequate treatment of the primary tumor as well as for the cortisol excess.Prognosis depends on the differentiation and type of the primary malignancy.
SummaryThe objective of the study is to report a case of acute pancreatitis secondary to hypercalcemia induced by primary hyperparathyroidism in a pregnant woman at the end of the first trimester. The case included a 32-year-old woman who was diagnosed with acute pancreatitis and severe hypercalcemia refractory to many regimens of medical therapy in the first trimester of pregnancy. She was successfully treated with parathyroidectomy in the early second trimester with complete resolution of hypercalcemia and pancreatitis. Neonatal course was unremarkable. To our best knowledge, this is a rare case when primary hyperparathyroidism and its complications are diagnosed in the first trimester of pregnancy. In conclusion, primary hyperparathyroidism is a rare life-threatening condition to the fetus and mother especially when associated with complications such as pancreatitis. Early therapeutic intervention is important to reduce the morbidity and mortality. Parathyroidectomy performed in the second trimester can be the only solution.Learning points:Learning how to make diagnosis of primary hyperparathyroidism in a woman during the first trimester of pregnancy.Understanding the complications of hypercalcemia and be aware of the high mortality and sequelae in both fetus and mother.Providing the adequate treatment in such complicated cases with coordinated care between endocrinologists and obstetricians to ensure optimal outcomes.
Introduction: Insular variant of papillary thyroid carcinoma is a rare pattern. Here, we report a case of poorly differentiated invasive insular variant of papillary thyroid cancer. Case: A 55 year-old lady presented with 5 years history of an anterior neck mass. In fact she had thyroidectomy performed many years ago and she was on levothyroxine suppression therapy. Thyroid ultrasound revealed right thyroid heterogeneous macrocalcification with compression of the trachea. She was treated with surgery and histology confirmed "insular thyroid papillary carcinoma growth. She received multiple sessions of radiotherapy planned to receive radioactive iodine. Conclusion: Insular thyroid carcinoma is a rare entity of papillary cancer. It is aggressive in nature and has a poor prognosis. This pathology requires an early diagnosis and treatment in order to improve the survival.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
