“…The recurrent sarcoma in the case reported by Young et al 15 was positive for vimentin and desmin, but negative for the other muscle markers: SMA and muscle common antigen. Other cases 19,28,29 showed a similar immunohistochemical profile to that reported by Young et al 15 In contrast, the case reported by Yum et al 7 showed positive reactions to vimentin, and the muscle markers muscle-specific actin, and desmin. Yum et al called it leiomyosarcoma arising in phyllodes tumor.…”

“…Yum et al called it leiomyosarcoma arising in phyllodes tumor. From these cases 15,19,28,29,30,[38][39][40] it appears that PSS can affect patients with a wide age range, and the prognosis is dependent on the grade and stage of disease.…”

“…When tested by immunohistochemistry the prostatic stromal cells are positive for androgen and progesterone receptors but not for estrogen receptors. [1][2][3] Many authors described lesions arising from the specialized prostatic stroma under several designations, including atypical stromal hyperplasia, 4,5 atypical stromal smooth muscle hyperplasia, 6 atypical fibromuscular hyperplasia, 7 phyllodes type of hyperplasia, [8][9][10][11][12] phyllodes tumor, 7,12-17 cystadeno-leiomyofibroma, 18 prostatic cystic epithelial stromal tumor, 19 cystosarcoma phyllodes, [20][21][22][23][24][25][26] pseudosarcomatous lesions of the prostate, 27 malignant phyllodes tumor of the prostate, 14,15,22,23,28,29 and stromal sarcoma of the prostate. 30 Gaudin and colleagues reported their experience with 22 tumors of the specialized prostatic stroma and proposed a unifying concept under which many of the previously described entities could be included.…”

Many significant benign and malignant nonepithelial tumors and stromal tumor-like lesions arise in the prostate gland. Although such lesions are rare, their recognition by the pathologist is essential because their treatment and prognosis are quite variable. In this review, lesions of the specialized prostatic stroma, that is, lesions that can be seen in the stroma of the prostate but not in that of other organs, except for the phyllodes type of lesions, are discussed. Benign and malignant lesions of the soft tissues that occur in the stroma of other organs and are seen with some frequency in the prostate are also discussed. Few of the rarer soft tissue lesions are mentioned. Lesions and tumors with melanocytic differentiation, hematopoietic derivation, and germ cell tumors are described. It is hoped that this review will serve as a useful reference when encountering some of these lesions, all of which are referenced to their original and subsequent reports. Some non-English language references are also cited to reflect the international recognition of these lesions or to give credit to the author who first described the entity.

A Large Cystic Phyllodes Tumor of the Prostate

et al. 2009

We report a 65 year-old man with a large cystic phyllodes tumor of the prostate. The patient complained of abdominal discomfort and had a soft palpable mass. Computer tomography showed a solid and cystic mass in the pelvic fossa; the mass was adjacent only to the prostate. We excised the mass. Microscopic findings of the mass showed hyperplastic epithelium lined cysts with leaf-like intraluminal epithelia lined stromal projections, less than 2 mitotic counts/10 HPF, low-to-moderated cellularity, and mild-to-moderate cytoplasm atypia. The pathological findings were consistent with a phyllodes tumor of the prostate, a low-grade tumor. Twenty-eight months after the operation, the patient was well with no recurrence or metastases.

“…17,[51][52][53][54][55][56][57][58][59][60][61] There are at least two reported cases of stromal sarcoma of the 'phyllodes type' arising in the seminal vesicle without involvement of the prostate. 62 suggesting a potential for STUMPs to dedifferentiate into sarcomas in rare cases and justifying the term 'malignant potential' for STUMPs.…”
