Priapism usually involves the whole length of a corpus or two corpora. Rarely is priapism segmental, especially proximally, and seldomly does it involve all three corpora. The causes of priapism are varied, but priapism due to solid malignancy is an extremely uncommon entity. The usual malignancy is urogenital. The disorder is frequently a manifestation of extensive pelvic extension of the primary disease; less commonly, it is associated with pelvic recurrence after seemingly curative surgery. In cases of malignant recurrence, priapism is rarely the first sign of such recurrence. We report a case of proximal tricorporal priapism, secondary to penile metastasis of a bladder malignancy postradical cystoprostatectomy. In this case, priapism was the first sign of disease recurrence and occurred in the absence of pelvic recurrence. This is the first such report of which we are aware.
阴茎异常勃起通常累及一个或两个海绵体的全长。阴茎异常勃起呈节段性者极为罕见，尤其是近端节段性异常勃起，累及所有三个海绵体的情况也很少见。阴茎异常勃起的病因多种多样，但由实体恶性肿瘤引起的阴茎异常勃起是一种极其罕见的情况。常见的恶性肿瘤是泌尿生殖系统的。这种病症通常是原发性疾病广泛盆腔扩散的表现；较少见的是，它与看似根治性手术后的盆腔复发有关。在恶性肿瘤复发的病例中，阴茎异常勃起很少是这种复发的首发症状。我们报告一例近端三海绵体阴茎异常勃起病例，继发于根治性膀胱前列腺切除术后膀胱恶性肿瘤的阴茎转移。在该病例中，阴茎异常勃起是疾病复发的首发症状，且在无盆腔复发的情况下出现。据我们所知，这是首例此类报告。
