Paragangliomas (PGLs) are rare tumors with an incidence of 0.007% in pregnant women. Patients with PGLs commonly present with hypertension and tachycardia. This case report describes the evaluation and management of a multiparous woman at 32 weeks of gestation with syncope, hypoxia, and tachycardia as unusual presenting symptoms of PGL. Her symptoms were attributable to paradoxical effects of circulating catecholamines on downregulated alpha-adrenergic receptors resulting in decreased systemic vascular resistance.

SMARCA4-deficient non small cell lung cancer (SMARCA4-dNSCLC) has recently garnered increasing attention due to its high malignancy and poor prognosis. The literature suggests that in non small cell lung cancer (NSCLC), the loss of SMARCA4 frequently co-occurs with mutations in KRAS, KEAP1, and STK11 rather than in EGFR, ALK, and ROS1. Herein, we present the first documented case of SMARCA4-dNSCLC accompanied with rare mutations of EGFR exon 20 S768I and exon 18 G719X.

Background: Complex surgery during initial cancer treatment can limit surgical options when planning management of a secondary malignancy. Subtotal esophagectomy and pancreatoduodenectomy are the most invasive and difficult procedures in gastroenterological surgery. Surgical cases in which subtotal esophagectomy was performed after pancreatoduodenectomy with pancreaticogastrostomy are extremely rare and challenging procedures due to the resulting complicated anatomical changes.

Background: The coexistence of sickle cell anemia and multiple sclerosis in a single patient presents a rare and challenging clinical scenario, possibly favoured by the interplay between chronic inflammatory states and autoimmune processes.
Methos/results: We present the case of a 36-year-old woman with sickle cell anemia who developed progressive neurological symptoms leading to frequent falls and paraparesis; magnetic resonance imaging showed many periventricular, infratentorial, and both cervical and dorsal spinal cord lesions, leading to a diagnosis of multiple sclerosis. After a multidisciplinary approach the patient was successfully started on ofatumumab.
