Of the benign colonic epithelial neoplasms the villous papilloma, although rare, is reported to become malignant in 30--50%. This paper reports a retrospective study of 213 patients with a colorectal villous papilloma. The tumours were subdivided histologically according to Wheat and Ackerman (1958) into four different groups. 20% of the tumours contained either focal or invasive carcinoma. The histology of the tumour correlated significantly (p less than 0.01) with the size of the tumour with a more malignant grading of the larger tumours in general. Blood in the stool, diarrhoea, and mucoid discharge from the anus were the most frequent complaints. Malignant change of the tumour was found especially in older patients (eighth decade of life) and among women. Patients with a malignant villous papilloma complained significantly more of pain on defecation than patients with a benign tumour. Over 30% of the malignant tumours were already incurable at the time of discovery because of invasion of surrounding tissues and metastases.

Sarcomas of the prostate are rare tumors and are predominantly rhabdomyosarcoma in children and leiomyosarcoma in the young adult (less than 50 years). We report on a rare case of prostate sarcoma in a 49-year-old patient whose presenting features were those of rapidly evolving prostatism and dyschezia (rectal constipation). The diagnosis was established histopathologically by cytology and biopsy. Despite the initial chemotherapeutic treatment, the course of the disease was fulminant and the patient died from multiple lymphatic metastases. We discuss its embryonal origin, clinical features, differential diagnosis and underscore the need for sequential combined treatment with chemotherapy, surgery and post-operative radiotherapy.

FDG PET-CT imaging is increasingly accepted as a modality for evaluation of many malignancies, but FDG also can be accumulated intensely by inflammatory lesions. We present a case of a 60-year-old woman with intermittent fever, chills, fatigue, and dyschezia. CT scans indicated colon carcinoma with thoracic and retroperitoneal lymph node metastases. Whole body FDG PET-CT was performed to confirm and stage the malignant disease and showed intense FDG uptake in those lesions. However, histopathology confirmed tuberculosis. The literature describing FDG accumulation in constitutional tuberculous lesions is sparse, and one must be aware of patterns of FDG accumulation in tuberculosis in the diagnosing malignancies.

An 8-year-old terrier cross and a 10-year-old German Shorthaired Pointer presented to the University Veterinary Centre, Sydney, for investigation of long-standing tenesmus and dyschezia. Both patients had an annular adenocarcinoma at the colorectal junction. Exploratory laparotomy was performed and the affected large intestinal segment was removed by resection and anastomosis. In both dogs, the caudal mesenteric artery was intimately associated with the mass, necessitating its ligation and transection. Postoperatively, there was no evidence of anastomosis breakdown in either case and both animals recovered well from surgery. The dogs were euthanased 8 and 10 months, respectively, after surgery because of clinical signs relating to metastatic disease.

An 8-year-old castrated male hound mix was referred to the Purdue University Veterinary Teaching Hospital for severe lameness, pollakiuria, and dyschezia. On presentation, the dog was nonweight bearing on the right rear limb and the right carpus was diffusely swollen. Synovial fluid analysis from the right carpus revealed a population of epithelial cells displaying marked anisocytosis, anisokaryosis, multinucleation, and prominent, variably sized nucleoli. A metastatic carcinoma with presumed prostatic or urothelial origin was diagnosed based on cytomorphology. Subsequent cytologic evaluation of peripheral lymph nodes revealed the presence of a similar neoplastic population. The dog was euthanized and synovial fluid from both stifle joints, as well as impression smears of the prostate gland, were collected. Carcinoma cells were identified in each stifle joint and in the prostate gland. Immunocytochemistry was performed on synovial fluid smears from 2 of the joints (right stifle and right carpus) and on impression smears of the prostate gland. The neoplastic population in the joints and prostate gland showed strong immunoreactivity to uroplakin III, a urothelial marker, indicating metastasis of a transitional cell carcinoma to multiple joints. In addition, evidence for epithelial to mesenchymal transition was identified using cytokeratin, an epithelial marker, and vimentin, a mesenchymal marker. A necropsy was performed and histopathology confirmed the presence of metastatic transitional cell carcinoma in various tissues. This case illustrates the importance of considering metastatic disease when a patient is presented with severe lameness and joint pain, and the clinical utility of synovial fluid cytology for diagnosis of metastasis in these cases.
