Main Findings:
We report what to our knowledge is the first case of a giant multicystic cystadenoma of the Cowper's glands. An otherwise healthy 41-year-old man presented with acute urinary retention. Physical examination showed a perineal mass. Different imaging techniques demonstrated a multicystic tumor and en bloc excision was performed. Histological evaluation showed that the tumor arised from the bulbourethral glands; immunohistochemistry proved positive staining for high molecular weight cytokeratin. CASE HYPOTHESIS: Cystic tumors in the pelvis can arise from different structures. Malignancy should be ruled out. Surgical excision can be diagnostic and curative. Future implications: When evaluating a pelvic cystic tumor, Cowper's glands cystadenoma may be a differential diagnosis and must be considered. Similar to prostate cystadenomas, en bloc excision is the optimal treatment.
