Metastatic prostate cancer to the duodenum: a rare case

Polypoid Large Intestinal Involvement of Metastatic Castrate-Resistant Prostate Cancer: A Case Report

Introduction

Prostate cancer most commonly metastasizes to the bone and lymph nodes. Gastrointestinal metastasis has been noted in the literature but appears to be an exceedingly uncommon phenomenon. Large intestinal involvement in particular has been reported on only a few occasions, and never concomitantly with small intestinal metastatic involvement.

Case Report

We report the case of a 69-year-old gentleman with metastatic castrate-resistant prostate cancer with development of gastrointestinal symptomatology with extensive investigation eventually revealing small and large intestinal polyps subsequently confirmed to be representative of metastatic prostate cancer.

Conclusion

This case demonstrates the importance of maintaining a wide differential diagnosis in the context of gastrointestinal symptomatology in malignancy. Thorough endoscopic evaluation may be necessary in such cases in order to identify potential metastatic malignancy in otherwise relatively unremarkable appearing polyps.

Prostate cancer recurrence presenting as an isolated small bowel tumour

Prostate cancer is the most commonly diagnosed cancer in males and third most common cause of cancer deaths in Australia. With improved survival rates and increasing reports of metastatic disease, we can expect to see more interesting and unusual presentations of recurrent disease. We present the case of a 66-year-old male with a prostate cancer recurrence to small bowel after curative treatment. We present this case to raise clinical suspicion in the medical fraternity regarding cancer recurrence; Even in the absence of biochemical markers or typical clinical signs and symptoms.

Prostate cancer metastasis to the distal phalanx of the left hallux: The first confirmed case and literature review

Prostate cancer is one of the most common carcinomas in Asia, as well as all over the world. The vast majority of prostate cancer patients present with bone metastases, which mainly involve the axial bones, with pain as the most common symptom. The present study reports the first case of prostate cancer metastasis to the hallux in a 73-year-old man who presented with pain and a swollen phalanx of the left hallux. This symptom developed gradually over a period of several months and could not be improved with the common treatments. Due to a pathological fracture, amputation of the left phalanx was performed. Notably, the immunohistochemical examinations of the surgical sample demonstrated the presence of a metastatic lesion from prostate cancer. The present study describes an unusual presentation involving phalangeal metastasis in a prostate cancer patient, and a systematic review of reported cases of rare metastatic events in prostate cancer is also discussed.
