[Prostatic carcinoma presenting as an abdominal mass: a case report]

Area of Science:

• Oncology
• Urology

Background:

• Prostatic carcinoma is a common malignancy in older men.
• Abdominal mass presentation is an extremely rare initial sign of prostate cancer.

Observation:

• A 64-year-old male presented with a right lower abdominal mass.
• Physical examination revealed a firm, fixed abdominal mass.
• Rectal examination showed prostate induration, and biopsy confirmed well-differentiated adenocarcinoma.

Findings:

• The abdominal mass was initially misdiagnosed as a retroperitoneal tumor.
• Histological examination confirmed the mass as metastatic prostatic carcinoma, likely from pelvic lymph nodes.
• The patient underwent preoperative irradiation, resection, and bilateral orchiectomy.

Implications:

• This case underscores the importance of considering metastatic prostatic carcinoma in patients with unexplained abdominal masses.
• Early diagnosis and multimodal treatment can lead to favorable outcomes.
• Pelvic lymph node metastasis should be evaluated in advanced prostate cancer cases presenting with abdominal symptoms.
