Clinical Management of Prostate Cancer Metastasis to Pineal Gland: Case Report and Review of Literature.

BACKGROUND: Prostate cancer is the most common cancer among American men, with an incidence of approximately 233,000 cases per year. Intracranial metastases are rare and, specifically, metastasis to the pineal gland has only been reported in 2 postmortem cases in the literature. CASE DESCRIPTION: We present the first documented case of confirmed prostate cancer metastasis to the pineal gland in a living patient. The patient underwent an endoscopic third ventriculostomy and pineal lesion biopsy with complete resolution of his hydrocephalus and presenting symptoms. His biopsy results confirmed the prostate origin of the metastasis, and he subsequently underwent stereotactic radiosurgery for treatment of this lesion. CONCLUSIONS: This is the first report of the clinical management of metastatic prostate cancer to the pineal region and description of the clinical outcome. Although prostate cancer is the most common cancer in American men, metastasis to the pineal has only been reported twice from autopsy examinations. Overall, pineal tumors in the geriatric population are exceedingly rare and the age and comorbidities in this patient made management quite unique.

Strongyloides hyperinfection syndrome in an immunocompetent host resulting in bandemia and death.

Strongyloides stercoralis infection is usually asymptomatic but can result in a hyperinfection syndrome, most commonly triggered by acquired or iatrogenic immunosuppression. Here, we present a case of a man aged 60 years originally from a strongyloides endemic area with a medical history of alcohol abuse who presents with strongyloides hyperinfection syndrome (SHS) complicated by partial small bowel obstruction, pulmonary haemorrhage, large bandemia without eosinophilia and cardiac arrest resulting in death. This case is notable for the presence of bandemia and absence of eosinophilia, lack of historical risk factors for hyperinfection, specifically corticosteroid immunosuppressants, and dramatic decline in clinical status which ultimately resulted in the patient's death. Clinicians should suspect SHS in immunocompetent patients who are from an endemic area and who have persistent gastrointestinal and/or pulmonary manifestations in the absence of a clear cause.
