Malakoplakia is a rare disease. Clinical presentation is non-specific, making its diagnosis an incidental finding on histopathological analysis. The aim of this case report is to describe a patient diagnosed with colon, renal and soft tissue malacoplakia mimicking a locally advanced colorectal cancer. A 75-year-old man was admitted due to intense abdominal pain. No relevant findings at the physical examination. Computed tomography showed parietal thickening of the descending colon with left kidney, iliopsoas muscle and retroperitoneum involvement. An elevated blood serum creatinine, elevated glycated hemoglobin and urinary infection were detected. Surgery was decided for suspicious symptomatic colonic neoplasm. Left segmental colectomy with left partial nephrectomy and retroperitoneal soft tissue resection was performed. Pathology report was compatible with malakoplakia. Malakoplakia is a rare disease and may affect multiple organs. Because there are no clinical-specific findings, diagnosis is usually made with histopathological study of the surgical specimen.

[Acute pancreatitis due to hypercalcemia during pregnancy. Report of one case].

Rev Med Chil 2019 Aug;147(8):1078-1081

Clínica Indisa, Santiago, Chile.

Acute pancreatitis during pregnancy is uncommon and usually associated with gallstones. However other etiologies must be considered. We report a 24 years old woman with a 32 weeks pregnancy consulting for abdominal pain, nausea and vomiting. She had elevated lipase and amylase levels, a corrected serum calcium of 13.1 mg/dl and a serum phosphate of 1.6 mg/dl. A magnetic resonance colangiopancreatography showed an enlarged pancreas with inflammatory changes and a normal Wirsung duct. A parathyroid nodule was found on cervical ultrasonography. The patient was treated initially with cinacalcet with partial response. A parathyroidectomy was performed at 39 weeks of pregnancy with a good maternal and fetal evolution.
