Giant multicystic cystadenoma of Cowper's gland: a case report

Abstract

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.
