title: [Adenoid cystic/basal cell carcinoma of the prostate:case report].
abstract: Although most prostate carcinomas belong to the conventional acinar type, unusual variants have been reported. The adenoid cystic/basal cell carcinoma of the prostate is a rare tumor with distinctive histopathologic features. There are quite few publications in the literature concerning the diagnosis, treatment, and prognosis of this neoplasm. METHODS. A 71-year-old man had an increased PSA value (5.11 ng/dL); the prostatic biopsy examination was positive for adenoid cystic/basal cell carcinoma. For this reason we proceeded with radical prostatectomy. The histology examination showed an acinar conventional carcinoma and adenoid cystic/basal cell carcinoma. At eight months the patient did not show any recurrence. CONCLUSIONS. Various histologic and immunohistochemical features are helpful in recognizing the adenoid cystic/basal cell carcinoma of the prostate. Clinically, the only difference from a conventional adenocarcinoma is that the PSA value is usually normal or only slightly increased. This tumor has a biological potential that can result in metastases in some cases; the current treatment consists primarily in the surgical resection. A close, long-term follow-up is strongly recommended.
