Successful Pregnancy in Isolated 17,20-lyase Deficiency Without Glucocorticoid Use or Assisted Reproduction Techniques.

Isolated 17,20-lyase deficiency (ILD) is a partial form of 17α-hydroxylase/17,20-lyase deficiency that typically presents with infertility and lack of pubertal development. Successful live births have been achieved using assisted reproductive techniques. We present a case of spontaneous pregnancy in an 18-year-old female with ILD without reproduction treatments or glucocorticoid use.

Pheochromocytoma/Paraganglioma (PPGL): A Misdiagnosed Cause of Hypertension during Pregnancy.

Hypertension (HT) during pregnancy is not an infrequent obstetric problem, reaching a prevalence of 5-10%. This condition is highly associated with both maternal and fetal complications if not precisely diagnosed and managed. Even though primary HT, obesity, and preeclampsia are the main causes of HT in this period, other less familiar conditions must be considered during the investigation.

Germline genetic variants in pheochromocytoma/paraganglioma: single-center experience.

Pheochromocytoma and paragangliomas (PPGLs) are rare neuroendocrine tumors carrying 25-40% pathogenic germline gene variants (PGVs). We evaluated clinical, laboratory, and germline molecular profile of 115 patients with pathologic (14 patients were relatives from 8 different families recruited for genetic survey) confirmed PPGL followed in our institution. Patients with classic MEN2A/MEN2B phenotypes and at-risk relatives underwent direct analysis of proto-oncogene, and the remaining had samples submitted to complete next-generation sequencing aiming 23 PPGL-related genes: and .

The Pheochromocytoma/Paraganglioma syndrome: an overview on mechanisms, diagnosis and management.

Pheochromocytomas/paragangliomas (PPGL) are rare, metastatic, and potentially fatal neuroendocrine tumors, often neglected because they present symptoms similar to other prevailing clinical conditions such panic syndrome, thyrotoxicosis, anxiety, hypoglycemia, etc., delaying diagnosis and treatment. The rate of diagnosis of PPGL has been increasing with the improvement in the measurement of catecholamine metabolites and the expanding availability of imaging procedures.
