Basaloma of the prostate gland(a case report and review of the literature) / 中华泌尿外科杂志

ABSTRACT

Objective To improve the recognition in the diagnosis and treatment of basaloma of the prostate gland.Methods A case of basaloma of the prostate gland was reported,and the relevant litera- ture was reviewed to investigate the histogenesis,diagnosis and treatment of this disease.A 67-year-old male patient suffered from intermittent gross hematuria for 3 years.He hadⅡ?hyperplastie prostate gland,and the right lobe of the prostate was elevated obviously in hard texture.The PSA level was 5 ng/ml.The prostate biopsy result showed glandnle-like basaloma of the prostate gland with low potential malignancy.After chemo- therapy with of Flutamine for 45 d,the patient underwent radical prostatectomy.Results Postoperative pa- thology showed that the tumor had intact capsule and was lobulated.The tumor cell was small in volume with ovoid karyomegaly and seldom caryokinesis.Some of the cells arranged like fruit nest,and infihratively grew. Proliferated basilar cells of the prostate were found in marginal part of the tumor.The pathological diagnosis was basaloma(adenoid cystic carcinoma)of the prostate gland.Postoperatively,the patient recovered well with no urinary incontinence or hematuria.During a follow-up of 2 years,the patient had no recurrence. Conclusions Adenoid basal cell carcinoma/adenoid cystic carcinoma is a clinically rare subtype of adenoid carcinoma of the prostate with low PSA level,low potential malignancy,slow growth,late metastasis and better prognosis.Radical prostatectomy is recommended for this disease.
