A five-year-old female patient presented to a family medicine clinic with a new, painless lump in the left supraclavicular fossa. She presented following a viral illness six weeks prior. She was otherwise well, with no fever, weight loss, night sweats, bruising, bleeding or jaundice. Examination confirmed concerning features of a firm, discrete, immobile mass measuring 4 cm in diameter. The location and examination features were treated as high-risk suggestive of malignancy, and the child was referred urgently via a suspected cancer pathway. Neck ultrasonography suggested the presence of a cervical rib, and chest radiography confirmed the presence of a prominent left cervical rib with a minor vestigial right cervical rib. This case highlights a structured approach to paediatric neck lumps in primary care, the importance of recognising red flag features warranting urgent referral and the importance of considering a cervical rib as a benign cause of a supraclavicular neck mass, despite cervical ribs often presenting incidentally.
