Abstract Introduction: Recurrent parotitis is defined as the occurrence of two or more episodes of the parotid gland. Several etiologies should be addressed in the approach to these patients. The aim of this study was to investigate the clinical, laboratory, and imaging profile of children with recurrent parotitis. Material and Methods: Retrospective review of the medical records of patients referred to a Pediatric Outpatient Clinic between January 2013 and June 2018. Results: The medical records of 24 patients with recurrent parotitis (66.7% male) and a mean age of seven years and five months were reviewed. The median age of onset of episodes was five years and three months. Unilateral and non-febrile episodes prevailed. Non-steroidal anti-inflammatory drugs were universally used to treat symptoms. Non-acute parotid and neck ultrasound predominantly showed the presence of a heterogeneous gland (57.1%). Sialography performed in five patients suggested chronic parotitis in two and Sjögren syndrome/ sarcoidosis in one. No significant immunologic defects were found beside a mild C3 reduction in one patient and C4 reduction in another patient, apparently without clinical relevance. A single patient tested positive for antinuclear antibodies. Immunoglobulin A deficit was found in one case. The most common final diagnosis was juvenile recurrent parotitis (37.5%). Conclusions: Most cases of recurrent parotitis in pediatric age have benign etiology. A more judicious request of complementary exams in the acute and non-acute phases could be time- and cost-effective.
