Aim To report the first documented case of paediatric salivary lymphadenoma in Australia/New Zealand and the youngest worldwide, and to improve patient outcomes by reviewing current evidence on clinical presentation, histopathology, and outcomes of this rare salivary pathology. Methodology A 9-year-old female presented with a five-month history of a right parotid mass, intermittent swelling, and pain. Laboratory investigations were performed, and ultrasound imaging evaluated lesion characteristics. The patient underwent a right superficial parotidectomy with intraoperative facial nerve monitoring, and the excised lesion was examined histopathologically. A review of previously reported paediatric cases was conducted to assess clinical features, histopathology, treatment, and outcomes. Results Ultrasound revealed a 29 × 20 × 16 mm lesion with solid and cystic components. Surgery was uneventful, achieving complete excision. Histopathology confirmed non-sebaceous lymphadenoma, showing cystic spaces lined by squamous epithelium with surrounding lymphoid follicles, without sebaceous differentiation or malignancy. Postoperative recovery was uneventful, with no complications at four-month follow-up. Literature review identified nine paediatric cases, with NSLA predominating (6 of 9). Lesions were mostly parotid-based, with rare extraparotid involvement. Complete surgical excision was curative, and no recurrences have been reported in children. Malignant transformation is exceedingly rare, reported only in adults. Gender distribution in paediatric cases is equal, contrasting adult patterns. Conclusion Paediatric salivary lymphadenoma is rare, predominantly non-sebaceous, and mainly parotid-based, with equal gender distribution. Complete surgical excision is curative, with negligible recurrence. Awareness of this rare pathology in paediatric patients with parotid or salivary lesions facilitates accurate diagnosis and guides optimal management.
