title: Malignant clear cell hidradenoma: a case report.
abstract: A 73-year-old man developed a malignant clear cell hidradenoma on the nose. Although it was treated solely with diathermy and curettage it did not recur. These rare tumours are histologically malignant but do not always behave aggressively. In some patients local growth and recurrence may occur, while in others the tumour metastasizes widely. There is no way of predicting how these tumours will behave.
