title: Primary squamous cell carcinoma of seminal vesicle: an extremely rare case report with literature review.
abstract: Primary squamous cell carcinoma of seminal vesicle is extremely rare, and most cases regarding seminal vesicle tumors failed to address this kind of tumor. A 54-year-old male patient presented with intermittent painless visual hematuria for 6 months was hospitalized. Ultrasonography, computerized tomography and magnetic resonance imaging demonstrated a 4.4 cm × 3.6 cm × 3.0 cm mixed tumorous lesion in the left seminal vesicle. A transrectal needle biopsy revealed severe chronic inflammation. The mass was completely resected in a laparoscopic approach and was verified as a moderately differentiated squamous cell carcinoma in the seminal vesicle by post-surgical histopathological examination. The patient received totally 5 cycles of chemotherapy. A rectal metastasis was detected 7 months after the surgery.
