The authors report the case of an 81-year-old male who presented with a 3-year-history of a bluish, nodular tumour located on the extensor side of his right forearm. Subjective symptoms included tenderness upon palpation and spontaneous haemorrhage. In order to exclude malignant neoplasms, for example, nodular melanoma, metastatic melanoma or angiosarcoma, the tumour was surgically removed and tissue submitted for microscopic examination. Histologically, the authors diagnosed this as giant vascular eccrine spiradenoma, a rare variant of eccrine spiradenoma, which can easily be mistaken for angiomatous lesions due to the haemorrhagic features and florid vascularisation. It is our aim to help clarify the diagnosis and differentiate giant vascular eccrine spiradenoma from other painful cutaneous tumours exhibiting a high degree of vascularisation, for example, angiosarcoma or venous thrombosis, as this case represents one of only seven found in published literature.
作者报告了一例81岁男性病例，其右前臂伸侧有一个蓝色结节状肿瘤，病史长达3年。主观症状包括触诊时有压痛和自发性出血。为了排除恶性肿瘤，如结节性黑色素瘤、转移性黑色素瘤或血管肉瘤，该肿瘤被手术切除，并将组织送检进行显微镜检查。组织学上，作者将其诊断为巨大血管性小汗腺螺旋腺瘤，这是小汗腺螺旋腺瘤的一种罕见变体，由于其出血特征和丰富的血管化，很容易被误诊为血管瘤样病变。我们的目的是帮助明确诊断，并将巨大血管性小汗腺螺旋腺瘤与其他表现为高度血管化的疼痛性皮肤肿瘤，如血管肉瘤或静脉血栓形成相鉴别，因为该病例是已发表文献中仅有的七例之一。
