Hepatic Artery Thrombosis: A Rare Complication of Microwave Ablation in Hepatocelluar Carcinoma.

Microwave ablation (MWA) has become a popular therapeutic technique in hepatocellular carcinoma (HCC) alongside cryoablation, radiofrequency ablation, and liver resection/transplantation in patients with limited tumor burden. Generally well tolerated, and not as invasive as surgery, the technique results in low mortality and complication rates. We report the exceedingly rare complication of hepatic artery thrombosis with subsequent fatal ischemia of the left hepatic lobe in a 64-year-old female with cirrhosis and HCC who underwent MWA.

Secondary Gastrointestinal Melanoma of Unknown Origin: A Case Report of a Rare Entity.

Metastatic oculocutaneous melanoma is a malignant process most commonly identified in the lungs, bone, gastrointestinal tract (most frequently the liver), and brain. In most cases, the primary oculocutaneous lesion responsible for the metastases is identified. However, in very rare cases, patients present with metastatic lesions with an occult primary site, termed melanoma of unknown primary (MUP), secondary to the partial or complete regression of the primary lesion. We describe the case of an 89-year-old male whose initial diagnosis of achalasia was later identified to be MUP in the cardia of the stomach with protrusion into the esophagus.

A Rare Case of Clostridium difficile Enteritis: A Common Bug in an Uncommon Place.

Clostridium difficile (CD), a bacterium responsible for causing 15%-25% of all cases of infectious diarrhea, is most commonly associated with infection of the colon. Rarely, though with increasing frequency, it has been noted to infect the small intestine in what is referred to as CD enteritis. We present the case of a patient who was diagnosed and treated for CD enteritis, review the pathophysiology behind the infection, and discuss the diagnostic and treatment options available to healthcare professionals.
