Discharge Summary:

Patient: [Name], 53-year-old male of Puerto-Rican origin

Diagnosis: Pheochromocytoma and paraganglioma 

Hospital Course:
The patient presented with persistent hematuria, urinary frequency, weak stream, and nocturia. CT urogram indicated bilateral, irregular, heterogeneous large adrenal masses. Biochemical characterization of masses showed significantly elevated 24-hour urine normetanephrine, leading to the diagnosis of pheochromocytoma. Negative symptoms included flushing, headaches, sweating, palpitations, anxiety, blurry vision, or dizziness, and no history of adrenal tumors, hyperparathyroidism, medullary thyroid cancer, renal cancer, or pituitary tumors. Ultimately, the patient underwent an open bilateral adrenalectomy and paracaval lymph node excision.

Pathology:
Surgical pathology confirmed pheochromocytomas in the bilateral adrenal glands. The paracaval lymph node was described as paraganglioma versus metastatic pheochromocytoma.

Genetic testing:
The patient was offered genetic screening for familial paraganglioma syndromes. With the patient's informed written consent, genomic DNA was isolated from a peripheral blood sample and targeted gene sequencing was performed using PGLNext. The patient was found to have a heterozygous germline mutation, c.524A>G in the VHL gene, corresponding to the Y175C substitution in the protein. This was identified as a likely pathogenic variant and confirmed by Sanger sequencing.

Treatment:
The patient required vasopressor support and a large amount of crystalloid resuscitation to maintain hemodynamic stability. Intraoperative ultrasound was used to identify one mesenteric lymph node of mildly suspicious appearance which was resected, in addition to a large retroperitoneal paracaval lymph node. The patient was started on life-long glucocorticoid and mineralocorticoid replacement.

Outcomes:
The patient's diabetes and hypertension resolved.

Follow-up:
Due to the multifocal nature of the pheochromocytomas and the presence of first-degree relatives likely to be affected, the patient was offered further genetic testing for familial paraganglioma syndromes. 

Overall, the patient's hospital course was unremarkable.
