A Rare Case of Metastatic Uveal Melanoma Responding to Immunotherapy.

Uveal melanoma (UM) is an intraocular malignancy with poor survival rates due to the propensity for metastatic spread. Although treatment options exist for localized disease, there are fewer definitive guidelines for metastatic UM. Treatment involves a personalized approach that entails patient-specific aspects, including tumor genetics. This case highlights the disease course of a 60-year-old male diagnosed with stage IIB right eye choroidal melanoma. Despite successful therapy for localized UM, he developed widespread metastasis. He received dual immunotherapy and was ultimately maintained on a single-agent regimen. His prognosis has surpassed initial prognosis and survival expectations. This case highlights the use of immunotherapy, both dual and single therapy, to treat this rare malignancy and extend overall survival.

A Case of a Mass of the Pancreatic Head Presenting as Mixed Hemorrhagic and Septic Shock.

Acute cholangitis is a biliary tract infection secondary to the obstruction, which causes biliary stasis and bacterial overgrowth. Typically, it presents with the Charcot triad of right upper quadrant abdominal pain, jaundice, and fever. Most acute cholangitis cases are secondary to choledocholithiasis. There are rare cases resulting from pancreatic neoplasm. We report the case of a 43-year-old Caucasian male who was found unresponsive at home with hypotension, anemia, and severe jaundice. Initial imaging studies were notable for a periampullary mass lesion causing intrahepatic biliary ductal dilation. Endoscopic retrograde cholangiopancreatography (ERCP) revealed an actively oozing periampullary fungating mass. In this case, acute cholangitis and hemorrhagic shock secondary to bleeding periampullary lesions are atypical. This case presents an effective treatment plan for this condition.

Pleural Effusion Secondary to Dasatinib Following Allogenic Hematopoietic Stem Cell Transplantation.

BACKGROUND Pleural effusions are frequently seen among patients with hematopoietic stem cell transplantation (HSCT). In the majority of cases, they are related to infections and volume overload. Medications have also been reported to cause pleural effusion in the general population, albeit very rarely. Dasatinib-induced pleural effusion has been reported in patients with chronic myeloid leukemia but not in those with HSCT. We here report a case of dasatinib-induced pleural effusion following HSCT for acute lymphocytic leukemia (ALL). The proposed mechanism of dasatinib-induced pleural effusion involves build-up of fluid due to an immune-mediated vascular insult. CASE REPORT A 72-year-old man who received HSCT for ALL was treated with dasatinib to prevent a recurrence. After 6 months, the patient was admitted to the hospital for pneumonia, which was observed as bilateral pleural effusion upon chest X-ray. After completing the antibiotics course, he developed recurrent pleural effusion during hospitalization. Repeated thoracentesis of the fluid revealed an exudative lymphocytic effusion with negative culture and cytology. Dasatinib was withdrawn and the pleural effusion resolved gradually. CONCLUSIONS In patients with dasatinib-induced pleural effusions following HCTS, withdrawal of the drug leads to symptom resolution, thereby avoiding unnecessary procedures. This case illustrates that dasatinib-induced pleural disease typically manifests with lymphocytic exudative fluid. Physicians should be aware that pleural effusion is a possible medication-related adverse effect, which may be missed in cases of infection in patients following HSCT.
