To investigate the diagnosis, differential diagnosis and prognosis of stromal tumors and tumor-like lesions of the prostate.


By means of HE, immunohistochemistry and electron microscopy, the clinical and histological data of 16 cases with stromal tumors and tumor-like lesions of the prostate were observed. Some of them were followed-up.


Of the 16 cases, 6 presented stromal nodular hyperplasia, 3 were stromal sarcoma, 1 malignant phyllodes-type tumor, 3 leiomyosarcoma, 1 fibrosarcoma, and one non-Hodgkin's lymphoma.


Nearly all the leiomyomas of the prostate diagnosed previously are, in fact, stromal nodular hyperplasia. The phyllodes-type tumors are often confused with stromal sarcomas in needle biopsy specimens and cause difficulty in differential diagnosis. Diagnostic criteria of leiomyosarcoma, fibrosarcoma, non-Hodgkin's lymphoma of the prostate are the same as their counterparts in the soft tissue. Non-epithelial malignant tumors in prostate are of poor prognosis.
