“…Fain JS et al reported the first case of high-grade phyllodes tumor of the seminal vesicle, with a lung metastasis four years after cystoprostatoseminovesiculectomy. They proposed that like breast and prostate tumors, phyllodes tumors of the seminal vesicle should be considered high-grade lesions (malignant) with significant mitotic activity, stromal pleomorphism, and stromal overgrowth [8]. Abe et al reported a patient suffering from cystosarcoma phyllodes of the seminal vesicle who died 11 months after tumor removal by open operation [9].…”

The current report presents the case of a 42-year-old male with extraordinarily salient urination difficulty that had lasted 6 months. Transrectal ultrasonography and pelvic magnetic resonance imaging demonstrated prostatic hyperplasia and cyst. PSA level was 20.65 (>4) μg/L in the patient. Transrectal prostatic biopsy revealed benign prostatic hyperplasia. He agreed to receive plasmakinetic resection of the prostate. During operation a lobulated lump was unexpectedly found on the verumontanum, with the prostate macroscopically normal. Complete tumor excision was performed and pathological assessment indicated phyllodes tumor of the verumontanum. The patient had an uneventful post-operative course and recovered well. The diagnosis, histological classification, treatment, and prognosis of this case are presented. It is necessary to perform cystoscopy to exclude verumontanum tumor even when all imaging examinations indicate prostate hyperplasia, especially in young males.Virtual SlidesThe virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/1868931661161758

“…Phyllodes tumors with varying degrees of malignant potential have been reported in the prostate, including cystosarcoma phyllodes. Adenofibroma and adenosarcoma of the female genital tract are histologically similar to phyllodes tumors and are considered of müllerian origin [4]. …”

Cystosarcoma of the seminal vesicle is a very rare malignant tumor; in the literature only four cases are reported. We present a case of cystosarcoma phyllodes arising in the right seminal vesicle of a 49-year-old man without any urinary symptom but with persistent constipation. Ultrasound examination showed a mass at the right superior base of the prostate subsequently studied with CT and MRI. The patient underwent vesiculectomy; his postoperative course was uneventful. The patient is still well, without evidence of recurrent disease.

“…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. 3 Indeed, in Herawi and Epstein's series of 50 stromal tumours of the prostate, seven of 14 stromal sarcomas were associated with STUMP.…”
