Renal granulomas related to suture material are rare and usually accidental findings in imagiological studies. A 12-year-old boy, followed-up after Anderson-Hynes pyeloplasty 7 years before, was submitted to an ultrasonography that described a solid nodular lesion, possibly in the dependence of the left kidney. Subsequently, magnetic resonance imaging was performed, which reported a lesion with non-specific features, suggesting neoformation with predominant fibrous peripheric component and myxomatous center. Percutaneous biopsy was morphologically compatible with chronic xanthogranulomatous inflammatory process. Anatomopathological examination of the surgical excised lesion described histiocytic cells with frequent participation of foreign body type giant cells and granulomatous reaction in relation to exogenous suture-like material. He remains asymptomatic since then. Foreign body granulomatous pseudotumors are difficult to diagnose regarding the absence of specific imagiological features distinctive from neoplasms, requiring histological examination to confirm the diagnosis.

Demographic aging, multiple pathologies and polymedication reinforce the importance of medication reconciliation: a complex and continuous process that aims to keep the medication list updated and complete during the various transitions between patient care. Patient safety is a main goal of medication reconciliation, which implies the prevention of medication errors, risks and possible injury associated with them, such as duplication, omission or drug interactions. This article is a reflection on the importance of medication reconciliation, its implications for the patient's health, the risks associated with its non-compliance as well as possible solutions and adaptations of health care required to quality in health.
