A 53-year-old Cambodian woman presented with nodular masses on the right arm suggestive of a sarcoma-type malignancy. The masses were excised and identified as multiple benign eccrine poromas. The patient re-presented after two years with large relapsed tumours and axillary lymph node involvement. A forequarter amputation was undertaken. Histology confirmed the diagnosis of a porocarcinoma, which was likely to be due to malignant transformation of the original poromas. The size and multiplicity of the tumours represents a highly unusual presentation of these rare eccrine neoplasms.
一名53岁的柬埔寨女性因右臂出现结节状肿块就诊，提示为肉瘤样恶性肿瘤。这些肿块被切除，病理确诊为多发性良性小汗腺汗孔瘤。两年后患者复发，出现巨大肿瘤并伴有腋窝淋巴结受累，遂行上肢截肢术。组织学检查确诊为汗孔癌，可能是由原来的汗孔瘤恶变所致。肿瘤的大小和多发性是这些罕见的小汗腺肿瘤极不寻常的表现。
