Beyond the Liver: A Unique Case of Pyogenic Liver Abscess Caused by Peptostreptococcus micros Penetrating the Chest Wall.

Liver abscesses are uncommon pyogenic infections with diverse microbiology, often involving enteric gram-negative bacilli such as Escherichia coli and Klebsiella pneumoniae. Standard management includes antibiotic therapy and abscess drainage. We present a case of a 37-year-old male with chronic right upper quadrant abdominal pain, who was found to have an enlarging liver mass infiltrating the chest wall and right-side chest ribs, ultimately diagnosed as a large pyogenic liver abscess (PLA) extending into the chest wall. Notably, the abscess was attributed to Peptostreptococcus micros, a rarely isolated pathogen in liver abscesses. Despite initial unsuccessful percutaneous drainage, surgical intervention proved necessary for definitive treatment. This case underscores the diagnostic challenge posed by uncommon pathogens in liver abscesses and emphasizes the effectiveness of surgical drainage in managing refractory cases.

Gastroduodenal Involvement in AL Amyloidosis: Case Report and Literature Review.

Gastrointestinal amyloidosis is a rare condition commonly found in the setting of systemic AL amyloidosis. Amyloid can deposit throughout the gastrointestinal tract and the resulting symptoms vary depending on the site of deposition. Gastrointestinal (GI) manifestations can range from weight loss or abdominal pain, to more serious complications like gastrointestinal bleeding, malabsorption, dysmotility, and obstruction. This case describes a patient with known history of IgG lambda AL amyloidosis, presenting with epigastric pain and unintentional weight loss found to have gastroduodenal amyloidosis. The definitive diagnosis of GI amyloidosis requires endoscopic biopsy with Congo red staining and visualization under polarized light microscopy. There are currently no specific guidelines for the management of GI amyloidosis. Generally, the goal is to treat the underlying cause of the amyloidosis along with symptom management. Our patient is being treated with cyclophosphamide, bortezomib, and dexamethasone (CyBorD) and started on hemodialysis due to progression of renal disease.

Abdominal Calcifications in a Patient From the Congo Basin with History of Snake Meat Consumption: Radiographic Evidence of Prior Armillifer Infection.

We report a case of a 60-year-old asymptomatic male with history of consumption of uncooked snake meat while living in the Congo basin and prior imaging showing multiple abdominal calcifications. Patient had multiple subepithelial colonic lesions identified during screening colonoscopy and microscopic examination of the lesions demonstrated a calcified nodule in the submucosa with overlying normal mucosa. However, no parasite was identified within the calcified nodule. Given the history of consumption of uncooked snake meat and the typical radiographic feature of multiple abdominal calcifications, it is very likely that the patient's radiographic abnormalities are due to prior Armillifer armillatus infection, a parasitic infection acquired from consumption of uncooked snake meat. Patient was asymptomatic at the time of evaluation and was not given anti-parasitic treatment.

Silica Desiccant Canister: An Unusual Colonic Foreign Body.

We are reporting a case of incidental identification and removal of two silica desiccant canisters from the cecum in a patient undergoing screening colonoscopy.
