A 43-year-old man presented with a tumour of the medial part of the right eyebrow. A biopsy was performed and histological examination revealed a malignant transformation of a 'calcifying epithelioma of Malherbe'. A secondary wide excision was performed. Clinical and pathological findings of this extremely rare tumour are reviewed. Factors influencing the prognosis are proposed, based on a compilation of the literature.
