Ultraviolet‐induced fluorescence dermoscopy (UVFD) is a novel adjunct technique in neoplastic and non‐neoplastic dermatoses. Ochre fluorescence (OF) in dermoscopically suspect lesions has been recently reported to be a strong clue to invasive melanoma. We report the case of a 76‐year‐old male with a multi‐coloured, irregularly shaped pigmented macule located on his sun‐damaged back. Dermoscopy was suggestive of superficial spreading melanoma (SSM), whereas UVFD revealed a central OF area. Although the lesion was scheduled for excision, the patient was subsequently lost to follow‐up and returned after 5 months. The lesion markedly enlarged clinically and dermoscopically, whereas the OF area expanded and became more pronounced. Pathology report confirmed the diagnosis of SSM.
