PASCUAL SAMANIEGO, Miguel et al. Cutaneous metastases from transitional cell carcinoma of the bladder producing ß-HCG. Actas Urol Esp [online]. 2009, vol.33, n.2, pp.209-213. ISSN 0210-4806.

In spite of the high incidence of transitional cell carcinoma, cutaneous metastases are infrequent, especially when they are the first sign of metastatic spread, with a low survival rate. Thirty five per cent of transitional cell carcinoma of the bladder have ectopic beta- human chorionic gonadotropin (ß-HCG) production. It has been related with high grade tumors, advanced stage, metastatic disease, radioresistent tumors and low survival rate because of its effect as a growth modulator with a probably antagonist action in the apoptotic cascade. We present a thirty six years old woman affected by a transitional cell carcinoma of the bladder producing ß-HCG that showed two cutaneous metastases as first sign of metastatic disease. The exceptional coincidence of these two circumstances announced a very aggressive tumor behaviour and bad prognostic, with a quickly multiple metastatic dissemination including a pericardic metastases.
