background: patients which have diagnosed with a cancer, have a life time risk for developing another de novo malignancy depending on various inherited, environmental and iatrogenic risk factors. cancer victims could survive longer due to settling treatment modalities, and then would likely develop a new metachronous malignancy. this article aims to report our observed trend of increasing, in p...

We report here a case of a random synchronous male breast malignancy in a patient with a known base of tongue malignancy that was incidentally detected on a whole body 18-fluorine deoxyglucose positron emission tomography and computed tomography ((18)F-FDG PET/CT). Patient was referred to us for PET/CT staging and radiotherapy planning for a poorly differentiated squamous cell carcinoma of base...

Positron emission tomography-computed tomography (PET-CT) has been shown to detect unexpected synchronous malignancies in up to 4.8% of patients and has been shown to be more sensitive than conventional staging alone. Detection of an unsuspected synchronous malignancy on PET-CT will often affect both patient treatment and prognosis. This article reviews expected patterns of disease spread so th...

background: the association between adenomatous polyps and malignancy has an important role in patient screening and follow up after polypectomy. due to less attraction towards the segmental resection, colonoscopic evaluation of malignancy has found its utmost importance role. polyp size and morphology have dictated the potential of malignancy in prior studies, however, in recent decade some au...

second primary malignancy following multiple myeloma (mm) was reported several years ago. there are also rare reports of cases with synchronous mm and other malignancies. to our knowledge, only one case of mm following bladder cancer has been reported in the literature. here, we report the second case occurred three months after diagnosis of bladder cancer.

Synchronous malignancies with an esophageal malignancy are not uncommon. However synchronous esophageal and renal cell carcinoma (RCC) is rare with only 11 cases reported in the world literature, the esophageal malignancies being adenocarcinomas or squamous cell carcinomas. Here, we report the first case of synchronous small cell carcinoma (SCC) of the esophagus with a RCC. SCC of the esophagus...
