With advances in diagnostic techniques and treatment modalities, the number of patients identified with colorectal carcinoma who develop multiple primary malignancies during long-term followup has been increasing. We report a patient who developed three histologically distinct malignancies. Primary colon carcinoma treated radically followed by an 8-year disease-free period. The patient then pre...

Synchronously occurring primary gynecological malignancies are rare, and most commonly reported synchronous female genital malignancies are ovarian and endometrial. It is postulated that the extended Mullerian system, comprising the ovarian epithelium, fallopian tube, uterine corpus and cervix, may respond as a single morphological unit to a carcinogenic process, thus producing primary tumours ...

Synchronous cancers are defined as malignant tumors that occur simultaneously. Each tumor must be primary which eliminate the possibility of being metastatic lesion of the other. If three separate organs are involved, that is so-called triple synchronous malignancy with very low morbidity. We report a case of a 33 year old male patient with triple synchronous malignancies at the colon, appendix...

Coexisting primary malignancies have been described at length in the literature. While double primary malignancies are relatively common, three synchronous primary malignancies are extremely rare. We describe a case of a 60-year-old woman undergoing surgery for a known endometrial carcinoma. The patient also had a renal mass that was identified as a clear cell renal cell carcinoma and an additi...

An increased association between neuroendocrine tumors of the gastrointestinal tract and pancreas (GEP-NET) and other second primary malignancies has been suggested. We determined whether there is indeed an increased risk for second primary malignancies in GEP-NET patients compared with an age- and sex-matched control group of patients with identical malignancies. The series comprised 243 men a...

While renal cell carcinoma is the most commonly diagnosed neoplasm of the kidney, its simultaneous diagnosis with a gastrointestinal malignancy is a rare, but well reported phenomenon. This discussion focuses on three independent cases in which each patient was diagnosed with renal cell carcinoma and a unique synchronous gastrointestinal malignancy. Case 1 explores the diagnosis and surgical in...
