We report a rare case of synchronous duodenal carcinoma, colonic carcinoma and renal oncocytoma successfully treated using a one-stage surgical approach. Potential risk factors for multiple primary malignancies associated with duodenal carcinoma are discussed. This case illustrates several practice points for consideration: 1. Patients presenting with small intestinal carcinomas have a higher t...

ΒACKGROUND Synchronous multiple malignancies of the larynx are rare. We present a case here of synchronous primary laryngeal squamous cell carcinoma (SCC) and malignant fibrous histiocytoma (MFH) in a patient with hoarseness though with no history of exposure to radiation. Clinical, intraoperative, and histopathological findings in this patient are discussed. METHODS Wide laser excision of th...

BACKGROUND During minimally invasive pulmonary resection, both limited visualization and tactile feedback can make localization of pulmonary nodules and assessment for synchronous disease challenging. Intraoperative molecular imaging is an emerging technology that can enhance a surgeon's ability to detect cancers at the time of resection. CASE PRESENTATION In this report, we describe the appl...

BACKGROUND We report a case of synchronous rectal and prostate cancer treated successfully with simultaneous da Vinci robotic-assisted low anterior resection of the rectum and robotic-assisted laparoscopic radical prostatectomy to address both cancers. CASE PRESENTATION Recently, minimally invasive surgical techniques using da Vinci robot® system (Intuitive Surgical, Sunnyvale, USA) were intr...

Multiple primary malignant neoplasms (MPMN) are two or more malignancies in an individual without any relationship between the tumors. In recent years, increasing number of cases were reported. However, Synchronous double primary gastric and endometrial cancer are relatively rare to be reported. Here we present a rare case of synchronous double cancer involving the stomach and endometrium, whic...

BACKGROUND Multiple primary neoplasms in surviving cancer patients are relatively common, with an increasing incidence. Their impact on survival has not been clearly defined. METHODS This was a retrospective review of clinical data for all consecutive patients with histologically confirmed cancer, with emphasis on single versus multiple primary neoplasms. Second primaries discovered at the wo...

BACKGROUND AND AIM There is an increased incidence of secondary primary cancer (SPC) in patients with papillary thyroid carcinoma (PTC). The risk is stronger in the first year after the first malignancy (synchronous tumours). The aim of this study was to assess the prevalence of SPC in patients with PTC, and to analyse whether the timing of tumour presentation influenced the clinicopathological...

Primary breast lymphomas (PBLs) represent less than 1% of all breast malignancies. Intravascular large B-cell lymphoma (ILBCL) is a rare, aggressive form of extranodal lymphoma. Breast involvement has only been described in the literature once previously. ILBCL is characterized by the proliferation of tumour cells within the lumen of small vessels of involved organs, resulting in their eventual...

We report a case of synchronous primary colonic adenocarcinoma and malignant mesothelioma. A 61-year-old male presented with a six-month history of fatigue and weight loss. An abdominal computed tomography (CT) scan showed a 5.8 cm partially obstructing mass in the cecum with ascites and peritoneal thickening. A biopsy of the large mass showed an adenocarcinoma. Because the patient was clinical...

INTRODUCTION The incidence of multiple primary cancers is reported to be between 0.3% and 4.3%. The second primary lesion is identified either simultaneously with the primary lesion (synchronous) or after a period of time (metachronous). Few cases of metastasis of breast carcinoma to the esophagus and vice versa have been reported in the past. CASE PRESENTATION We report an extremely rare cas...
