We present a case of a 65-year-old male with a biopsy proven subcutaneous capillary haemangioma identified on imaging for evaluation of further metastatic spread of prostatic carcinoma due to a rise in his prostate-specific antigen biochemistry. He was receiving salvage radiation therapy for his known isolated nodal disease, four years after prostatectomy. An intensely avid prostate-specific membrane antigen positron emission tomography-computed tomography lesion in the left paramedian back at the level of L1 was noted on his scan. A core biopsy revealed a dermal haemangioma with no evidence of metastatic prostatic carcinoma. To our knowledge, only one other incidental case of prostate-specific membrane antigen avid subcutaneous capillary haemangioma has been described in the literature. Whilst uncommon, incidental findings of prostate-specific membrane antigen PET avid dermal lesions are pathognomonic for haemangiomas and can be treated as "no touch" lesions with watchful observation.
我们报告一例65岁男性病例，该患者因前列腺特异性抗原生化指标升高，为评估前列腺癌进一步转移扩散而进行影像学检查时，经活检证实存在皮下毛细血管瘤。他在前列腺切除术后四年，因已知的孤立性淋巴结疾病接受挽救性放射治疗。在他的扫描中发现，在L1水平左旁正中背部有一个前列腺特异性膜抗原正电子发射断层扫描-计算机断层扫描高度摄取的病变。一次穿刺活检显示为真皮血管瘤，没有前列腺癌转移的证据。据我们所知，文献中仅描述过另一例偶然发现的前列腺特异性膜抗原摄取的皮下毛细血管瘤病例。虽然不常见，但偶然发现的前列腺特异性膜抗原PET摄取的皮肤病变是血管瘤的特征性表现，可作为“不干预”病变进行密切观察。
