Background:
Prostatic adenocarcinoma is exceptionally associated with cutaneous lesions. We describe a patient with cutaneous lymphangitis and paraneoplastic ichtyosis related to prostatic cancer.
Case Report:
A 92 year-old man had been treated for five years for a prostatic carcinoma. An angiomatous lesion developed with in 3 months near the right breast. Physical examination revealed axillary node enlargement, a large skin angiomatous lesion, and ichtyosis. The skin biopsy of the angiomatous skin lesion demonstrated its prostatic origin with carcinomatous metastases in the lymphatic vessels. The ichtyosis was considered as paraneoplastic.
Discussion:
Cutaneous metastases from prostatic carcinoma are rare. Less than 1 p. 100 of cutaneous metastases are of prostate origin despite the high frequency of this cancer in the general population. The clinical aspects - angiomatous lesion and paraneoplastic ichtyosis - are exceptional.
