Medullary carcinoma of the thyroid gland is a feature of multiple endocrine neoplasia, type IIb (MEN IIb). The cancer frequently gives rise to metastases in early life. Marfanoid habitus and virtually pathognomic mucosal ganglioneuromas, often situated on the tongue, enable early diagnosis. These stigmata should alert the clinician to the possibility of MEN IIb before medullary carcinoma is clinically manifest. We now believe that it is reasonable to perform a total thyroidectomy in children with the typical physical appearance of this syndrome regardless of age since medullary carcinoma of the thyroid gland appears in almost every case. Calcitonin, a hormone secreted by the C-cells, serves as a plasma tumor marker. Intravenously administered, pentagastrin is a potent secretagogue which is very useful in the early diagnosis of either primary or recurrent medullary carcinoma. With this pentagastrin test, a laboratory screening program is possible allowing the clinician, specialist, to recognize the syndrome.

Primary signet-ring cell carcinoma of the prostate is infrequent and even more so as secondary spread of this pathologic sub-type to the prostate. We describe the sixth reported case with a diagnosis of a secondary signet-ring cell tumour of the prostate secondary to a gastric cancer. Five years post-gastrectomy to resect signet-ring cell carcinoma, we detected a secondary intra-prostatic spread with urinary tract obstruction. The physical appearance of the tumour cells was similar to that of the previously-resected signet-cell carcinoma of the stomach. There were no metastases in other sites and the patient was treated with radiotherapy. When confronted with intra-prostatic signet-ring cell adenocarcinoma it is necessary to distinguish between primary and secondary aetiology since this would reflect in the choice of treatment and prognosis.
