Key Clinical Message Renal cell carcinoma is a highly malignant neoplasm. Metastasis to the pancreas and gastrointestinal tract is rare. In this case report, we show images of metastatic renal cell carcinoma to the upper gastrointestinal tract in a patient who presented with melena.

Key Clinical Message Windsock diverticulum is a rare anomalous finding of a true intraluminal duodenal diverticulum. While complications of bowel obstruction, bleeding, and pancreatitis may occur, most patients are asymptomatic. Surgical or endoscopic management may be pursued when complications develop.

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) is a rare but potentially life-threatening cutaneous hypersensitivity reaction characterized by extensive mucocutaneous eruption, fever, hematologic abnormalities, and extensive organ involvement. Here, we present a case of a young woman with DRESS syndrome following exposure to vancomycin with renal, cutaneous, and gastrointestinal involvement. To the best of our knowledge, this is the first case description in the literature of DRESS of the gastrointestinal tract with autoimmune enteropathy.

Lymphoepithelial cysts (LECs) of the pancreas are benign, rare pancreatic cysts that are found predominantly in men. These cysts can present as a diagnostic conundrum given their rarity and difficulty of distinguishing these cysts from those with malignant potential. We present an incidental case of a LEC in a middle-aged man.
