RESUMO
Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis and remains a health problem, especially in developing countries. Abdominal location represents 5 to 10% of all locations. The clinical symptoms are not very specific, and the discovery of an abdominal mass in a context of deterioration of general state may wrongly lead to the diagnosis of a tumor. Radiological explorations remain sensitive in the detection of abdominal masses but they cannot prejudge their etiology. Surgical exploration is sometimes the only recourse either for diagnostic purposes or complications, and the diagnosis can only be confirmed by bacteriological and histological examinations of the surgical specimen. We report the case of abdominopelvic mass and lymph nodes revealing tuberculosis.
RESUMO
BACKGROUND: Insulinomas are rare pancreatic endocrine tumors. Most are benign and solitary. However, the nonspecific symptoms and small size of these tumors led to difficulties of diagnosis and localization. CASE PRESENTATION: We present two Arab patients with pancreatic long-standing insulinoma. Both patients presented episodic hypoglycemic symptoms respectively during 10 and 2 years. Biochemical and morphological workup detected localized pancreatic insulinoma. Open procedure surgery was done for the two patients and insulinomas were successfully removed by enucleation. CONCLUSION: Insulinoma remains a diagnostic challenge to practitioners. Diagnosis of suspected cases is easily confirmed by standard endocrine tests, especially the supervised fasting test. Accurate preoperative localization is essential for more effective and safest surgery.
