BACKGROUND Malignant neoplasm of the pancreas has become one of the leading causes of death from malignant neoplasm in Japan (the 5th in 2003). Although smoking is believed to be a risk factor, other risk factors remain unclear. Mortality from malignant neoplasm of the pancreas tends to be higher in northern Japan and in northern European countries. A recent study reported that standardized mor...
A decline of mortality dependence on age from the exponential relation is observed for some diseases. This decline could be explained by the existence of an inherently susceptible population subset which is depleted faster than the general population. A model is presented which describes this situation using malignant neoplasm of the brain. The model assumes that only those who are members of t...
Cystic lesions of the pancreas are more frequently recognized due to the widespread use of improved imaging techniques. There are a variety of pancreatic cystic lesions with different clinical presentations and malignant potentials, and their management depends on the type of the cysts. Although the early recognition of a cystic neoplasm with malignant potential provides an opportunity of early...

Malignant lymphoma is the most common neoplasm in 3rd and 4th decades of life and more than two third of affected patients presented painless peripheral lymphadenopathy.

Malignant peripheral nerve sheath tumor (MPNST) is an aggressive neoplasm of neural origin. It is a rare neoplasm of childhood, accounting for less than 5% of all cases. In 1994 a 29 months old boy was admitted to the Mofid Hospital with complaints of fever, dyspnea and respiratory distress. After performing all the necessary clinical and labratory tests a large mass in the upper posterior medi...
In 30 patient with single cold thyroid nodule and normal thyroid function tests, 99mTc-MIBI scan is performed. The nodules are divided to hot (10), Warm (12) and cold (8). FNA reported papillary Ca in 4, suspicious follicular neoplasm in 3 and 23 benign lesions. 7 patients were operated on and had final pathology reports (4 papillary Ca and 3 benign lesions). All the nodules with no MIBI ...
Primitive Peripheral Malignant Neuroectodermal Tumor is a malignant neoplasm of neural origin with high mortality which occurs mostly in children and adolescents. The most common site of involvements are chest wall and paraspinal regions. Head and neck involvement is rare. The diagnosis is based upon histopathologic and immuno-histochemical studies. Treatment is combination of surgery, radiothe...
BACKGROUND The kidney recipient is at a higher risk for cancer than is the general population, although the incidence of neoplasms in general is considered lower in Japan than in Western countries. The cause of this increased risk associated with either transplantation or geography has not yet been established. METHOD The incidences and sites of malignant neoplasms were analyzed in 285 kidney...
