In April 2017, an 81-year-old man presented to the emergency department with acute urinary retention. Digital rectal examination revealed a grossly enlarged prostate with a hard nodule felt at the left lobe. The patient was subsequently catheterised and haematuria with a small number of blood clots was noted. Urine cytology and microbiology were negative. Prostate-specific antigen (PSA) was elevated at 23.8 ng/mL.Cystoscopy revealed a trabeculated urinary bladder with multiple small bladder diverticula but no mucosal lesion and a grossly enlarged prostate. The patient was prescribed terazosin and successfully weaned off the Foley catheter. However, the patient required repeat admissions for recurrent acute urinary retention. He was managed with an increased dose of terazosin and intermittent selfcatheterisation.Computed tomography (CT) urogram was performed as part of the haematuria examination and revealed an approximately 10-cm hypodense cystic lesion in the rectovesical space. No preserved fat plane was present between the lesion and seminal vesicles and prostate, or the lesion and rectum. Internal enhancing solid components were seen in the left posterior aspect of the mass (Fig a and b).On magnetic resonance imaging (MRI), the mass was again noted between the rectum and the prostate. The mass showed predominantly T1-weighted hyperintense signal which could represent proteinaceous or blood product. In T2weighted sequence, the mass was heterogeneously hyperintense. A solid component previously detected on CT scan demonstrated T1-and T2weighted intermediate signal intensity, with restricted diffusion and contrast enhancement. (Fig c to g) The differential diagnoses included a seminal vesicle or prostatic tumour, a rectal tumour such as gastrointestinal stromal tumour, or a neuroendocrine tumour.A CT-guided biopsy was performed for histology. The centre of the mass was first biopsied and yielded old blood products. Cytology revealed necrotic cells and blood cells but no tumour cells.Hong Kong Med J 2020;26:66-9 https://doi.

“…However, cystic degeneration of prostate cancer is occasionally reported. [4–7] A case of prostate cancer, invading the right seminal vesicle with cystic changes, was the largest cystic variation of the prostate.

Rationale:Prostate cancer often metastasizes (most commonly to the pelvic lymph nodes and axial skeleton); however, metastases to the pelvic cavity as a solitary mass are unusual. While metastatic prostate cancer is unconventional in pelvic cavity, cystic pelvic lesions are even more scarce. Accurate identification of cystic metastasis can be helpful in management of prostate cancer.Patient concerns:A 64-year-old male was admitted to our hospital due to urethral irritation symptom and dysuria.Diagnosis:In addition to prostate cancer, abdominal computed tomography (CT) scanning and magnetic resonance imaging (MRI) of the prostate revealed that a cystic mass was located at right pelvic cavity. Histopathological examination diagnosed the pelvic cystic mass as metastasis from prostatic cancer. Immunohistochemistry results demonstrated Calretinin (+), D2-40 (−), Ki-67 (10%+), Vimentin (−), CK-pan (+), CK5/6 (−), WT-1 (−), PSA (+), SALL4 (−), Villin (−), CK20 (−), CK7 (−), PAX-8 (−), and TTF-1 (−).Interventions:The cystic mass was removed. Primary cancer of the prostate was reserved as well. After discharge, the patient underwent in a two-year androgen deprivation therapy (ADT) treatment.Outcomes:After 13 months of discharge, no disease progression was found in the patient.Lessons:Although cystic prostate cancer is rare, the occurrence possibility should be considered when cystic lesions are accompanied with prostate cancer.

Cystic formations in the prostate are quite common, but the vast majority are benign. The cystic form of prostate adenocarcinoma can present unexpected symptoms, and management can be difficult because of the local advanced stage of the disease. A unique feature of this case is the surgical local cancer treatment. In this clinical case, we describe the literature surrounding this rare form of neoplasm. We present a clinical case of a rare form of prostate cancer in a 71-year-old male who was admitted to ER with acute urinary retention. A huge obstructing prostatic cyst was revealed. After successful trial-without-catheter, the patient underwent transperineal cyst draining and this restored urination. PSAt was increased up to 55 ng/mL. The cystic wall biopsy revealed adenocarcinoma with a Gleason score of 8 (4+4) (Gleason Group IV), and distant metastasis was noticed with PSMA PET/CT. The patient started androgen deprivation therapy (ADT) with excellent PSA dynamics in three months. Because of lower urinary tract symptoms, he needed local treatment and underwent radical prostatectomy. A three-month follow-up demonstrated a common post-operative period, mild stress incontinence, and PSAt 0.004 ng/mL. Cystic prostatic carcinoma can manifest as urinary retention and be mistakenly taken for a benign obstructing prostate cyst. Despite the locally advanced tumor, it can be successfully treated locally in highly selected patients.
