Malignant eccrine spiradenomas are exceedingly rare tumors. They can arise from a preexisting eccrine spiradenoma or occur as a primary malignant tumor. Clinical features of these tumors may include a history of enlargement in a previously stable lesion. Tumor can be of low or high grade. Low-grade malignant eccrine spiradenoma has a better prognosis. We present a malignant eccrine spiradenoma arising from a preexisting eccrine spiradenoma, which has an infrequent localization between lateral edge of nose and medial canthus.
恶性小汗腺螺旋腺瘤是极其罕见的肿瘤。它们可由先前存在的小汗腺螺旋腺瘤发展而来，或作为原发性恶性肿瘤出现。这些肿瘤的临床特征可能包括先前稳定的病变出现增大的病史。肿瘤可为低级别或高级别。低级别恶性小汗腺螺旋腺瘤预后较好。我们报告一例由先前存在的小汗腺螺旋腺瘤发展而来的恶性小汗腺螺旋腺瘤，其位于鼻外侧缘与内眦之间，位置罕见。
