A 77-year-old male patient was admitted because of jaundice and general malaise. Exploratory laparotomy disclosed pancreatic head cancer with invasion to the intrapancreatic bile duct. Three months later, his daughter, aged 51, was admitted for evaluation because of body weight loss and back pain. CT scan disclosed 3 low-density areas in the pancreas with irregular margins and multiple low-density areas in the liver. Pancreatic cancer with liver metastasis was confirmed by autopsy. In familial pancreatic cancer, it is essential that genetic in addition to environmental factors be examined in pancreatic carcinogenesis.

Chromophobe renal cell carcinoma (RCC) and collecting duct carcinoma (CDC) are derived from the collecting duct epithelia, although their morphology, molecular biologic characteristics and clinical behaviors are quite different. Herein is presented a case of RCC possessing the chromophobe RCC and CDC elements occurring in a 64 year-old Japanese woman. The patient was referred to Yokohama City University Hospital with complaints of persistent back pain and fever. Radiologic examinations revealed a left renal tumor, and radical nephrectomy was performed. The patient died with multiple metastases, 8 months after the operation. The resected tumor showed an invasive growth, and its cut surface was heterogenous with hemorrhage and necrosis. Histologically, the tumor was composed of chromophobe elements with dedifferentiation, and CDC elements. The chromophobe and CDC elements had obvious histological transition. Lectin histochemistry and immunohistochemistry confirmed that this tumor was derived from the distal nephron. c-KIT, p53 and Ki67 antigen showed differential localization between the chromophobe and CDC elements, even in the transitional areas. Along with the previous reports, the present case seemed to be composite RCC derived from the collecting duct, which might present clues to elucidate carcinogenesis in the distal nephron.

Long-term outcomes after endovascular aneurysm repair (EVAR) for inflammatory aneurysms are unknown. We present a young patient with new-onset back pain and failure to thrive 6 years after EVAR for an inflammatory abdominal aortic aneurysm (AAA). Endograft explanation was performed with a presumed diagnosis of infection. Pathology revealed intimal sarcoma in the excluded aneurysm sac with liver metastasis. This report presents a detailed review of literature regarding potential association of prosthetic implantation and carcinogenesis.

A 54-year-old man with a history of smoking developed infectious bullae at the apex of his left lung and underwent long-term antimicrobial treatment. The bullae gradually reduced in size along with a slight left pleural thickening. Left back pain relapsed after a year, and CT revealed a rapid increase in pleural thickening. Left upper lobectomy led to the diagnosis of pulmonary polymorphic carcinoma. Chronic inflammation due to infection could contribute to carcinogenesis; therefore, post-inflammatory changes should be carefully followed-up.
