In a number of patients, radiotherapy following surgery for breast carcinoma may induce radiation injury to the lungs. This has classically been divided into an early radiation pneumonitis and a late fibrosis, both confined to the irradiated lung volume. However we observed a female patient who similarly to other recent reports in the literature developed a recurring pneumonitis migrating from one lung to the other after radiotherapy for breast carcinoma. This migratory BOOP (bronchiolitis obliterans organizing pneumonia) was characterized by a lymphocytic alveolitis and responded well to corticosteroids. Clinicians should be aware of the possibility of a lymphocytic pneumonitis in both lungs after unilateral thoracic irradiation and recognize the distinctive features of fever, cough, dyspnoea and malaise in order to start an effective treatment with corticosteroids. They should also be aware of the high tendency for recurrence when tapering off.

A total of 51 cases (19 males and 32 females) of intrahepatic cholangiocellular carcinoma (CCC) from a low-endemicity area of primary liver cancer was analyzed during the periods from 1958 to 1979 and from 1984 to 1991. The mean annual age-adjusted incidence rate was 0.44 for males and 0.56 for females per 100,000 inhabitants. CCC was diagnosed before death in only 31%. There was a female predominance in patients over 70 years of age (p < 0.05). At presentation, malaise (85%), weight loss (73%) abdominal pain (50%) and hepatomegaly (80%) were common. The median survival time from diagnosis was 2 months. The mean age at the time of death was 72 years (range 41-92). At autopsy, cholelithiasis was found in 61% (81% in patients older than 70 years) and cirrhosis in 30% of patients. Cholelithiasis was more common in CCC (p < 0.01) than in hepatocellular carcinoma cases with the same mean age. Not one case of inflammatory bowel disease was found. The gross appearance of the tumor was predominantly massive (49%) or multinodular (35%). The most common histological features were tubular pattern of growth (82%) and abundant fibrous stroma. Metastases were particularly associated with the lymph nodes (41%), skeleton (26%) and lungs (16%).

Of 99 patients operated on with subtotal pancreatectomy due to ampullary carcinoma, five had a local recurrence in the pancreatic bed at the ligament of Treitz. The patients all had distinct symptoms: recurrent bouts of fever, general malaise, and rapid loss of weight. They had little pain, but all were jaundiced in spite of absence of marked compression of the bile ducts. Computed tomography or ultrasound could not detect the small, local recurrence that was obstructing the jejunal loop 10-15 cm distal to the hepaticojejunostomy, but as an indirect sign of the recurrence, the distended small bowel loop proximal to the ligament of Treitz was clearly seen in all patients.

The vast majority of the human experience with viral infections is associated with acute symptoms, such as malaise, fever, chills, rhinitis and diarrhea. With this acute or lytic phase, the immune system mounts a response and eliminates the viral agent while acquiring antibodies to that specific viral subtype. With latent or chronic infections, the viral agent becomes incorporated into the human genome. Viral agents capable of integration into the host's genetic material are particularly dangerous and may commandeer the host's ability to regulate normal cell growth and proliferation. The oncogenic viruses may immortalize the host cell, and facilitate malignant transformation. Cell growth and proliferation may be enhanced by viral interference with tumor suppressor gene function (p53 and pRb). Viruses may act as vectors for mutated proto-oncogenes (oncogenes). Overexpression of these oncogenes in viral-infected cells interferes with normal cell function and allows unregulated cell growth and proliferation, which may lead to malignant transformation and tumour formation. Development of oral neoplasms, both benign and malignant, has been linked to several viruses. Epstein-Barr virus is associated with oral hairy leukoplakia, lymphoproliferative disease, lymphoepithelial carcinoma, B-cell lymphomas, and nasopharyngeal carcinoma. Human herpesvirus-8 has been implicated in all forms of Kaposi's sarcoma, primary effusion lymphomas, multiple myeloma, angioimmunoblastic lymphadenopathy, and Castleman's disease. Human herpesvirus-6 has been detected in lymphoproliferative disease, lymphomas, Hodgkin's disease, and oral squamous cell carcinoma. The role of human papillomavirus in benign (squamous papilloma, focal epithelial hyperplasia, condyloma acuminatum, verruca vulgaris), premalignant (oral epithelial dysplasia), and malignant (squamous cell carcinoma) neoplasms within the oral cavity is well recognized. Herpes simplex virus may participate as a cofactor in oral squamous cell carcinoma development by enhancing activation, amplification, and overexpression of pre-existing oncogenes within neoplastic tissues. Because of the integral role of viruses in malignant transformation of host cells, innovative antiviral therapy may prevent tumour development, involute neoplastic proliferations, or arrest malignant progression.

We report a 58 years old male, presenting with malaise, weight loss and jaundice. An abdominal ultrasound showed multiple lymphadenopathies in the hepatic bilus and around the pancreas. Fine needle aspiration of these nodes demonstrated an undifferentiated carcinoma. Prostate specific antigen was over 100 ng/ml and a prostate biopsy demonstrated a high grade carcinoma. The patient was subjected to an orchiectomy and hormone therapy (flutamide). Jaundice subsided and he is well after 3 years of follow up and maintained hormone therapy.

The prognostic significance of neuroendocrine differentiation in colorectal carcinoma is uncertain. We analyzed 289 moderately differentiated (grades II and Ill) colorectal carcinomas for neuroendocrine differentiation by immunohistochemistry and in situ hybridization. The tumors were divided into three groups based on the presence of and the numbers of neuroendocrine cells, with group I having no neuroendocrine cells, group II having <1 positive cell/mm(2), and group Ill with >1 positive cell/mm(2). In situ hybridization with probes for chromogranin A and B detected almost twice as many neuroendocrine cells as did immunostaining with an antibody for chromogranin A. There was no prognostic difference associated with the presence or absence of neuroendocrine differentiation in this group of moderately differentiated carcinomas. These results indicate that the presence of neuroendocrine cells detected by expression of chromogranin protein or mRNA does not influence prognosis in moderately differentiated colorectal carcinomas.

Epithelial cyst of the gallbladder associated with papillary adenoma and adenocarcinoma is presented herein. A 70-year-old male patient with general malaise was admitted to our hospital during the follow-up of an elevated mucosal lesion in the fundus of the gallbladder. Endoscopic ultrasonography revealed a cystic lesion adjacent to the elevated lesion, and interruption of the hyperechoic third layer of the gallbladder wall next to the gallbladder bed of the liver. He was diagnosed as having an epithelial cyst of the gallbladder associated with gallbladder carcinoma that directly invaded the gallbladder bed. He underwent resection of the gallbladder with partial resection of the liver and regional lymph node dissection. The resected specimen, which showed multiple cysts with septum formation, measured 1.9 cm in size and was located in the subserosal layer of the gallbladder wall. The wall of the cyst was lined with columnar epithelium and papillary adenoma, and adenocarcinoma was scattered in some portions of the cyst wall. Furthermore, papillary adenoma associated with adenocarcinoma was independently identified in the luminal surface of the gallbladder epithelium covering the cysts. These histological findings were compatible with epithelial cyst of the gallbladder associated with papillary adenoma and adenocarcinoma. The tumor was diagnosed as T1bN0M0, stage I, in the TNM clinical classification. To our knowledge, this is the first report of an epithelial cyst of the gallbladder associated with papillary adenoma and adenocarcinoma, and provides some insight into the relationship between epithelial cyst and adenoma or cystadenocarcinoma of the gallbladder.

We report a patient with gastric carcinoma successfully treated with TS-1/CDDP as a neoadjuvant chemotherapy. The patient was a 72-year-old man who had suffered from general malaise with severe anemia and was diagnosed as type 2 carcinoma, having bulky N2, with suspected invasion of the pancreas. TS-1 (100 mg/day) was administered orally every day for 21 days followed by 14 days rest, and CDDP (20 mg/body) was administered by intravenous infusion at day 8, as one course. He was treated as an outpatient, and two courses of treatment resulted in a marked reduction of the lymphnode metastasis without toxicity. Subsequently, he underwent curative surgery consisting of total gastrectomy with D2 lymph node dissection. TS-1/CDDP therapy is very useful as a neoadjuvant chemotherapy especially for an outpatient until surgery.

The management of metastasis from parathyroid carcinoma (PC) is an unusual challenge. Systemic therapy has minimal effect on the course of the disease and its associated hypercalcemia. Resection of isolated pulmonary metastases is an attractive option in the setting of recurrent hypercalcemia. We report a case of a patient who underwent resection of multiple functional PC pulmonary metastases almost 20 years after the original neck resection. The patient originally presented in 1982 with what was thought to be hyperparathyroidism secondary to a parathyroid adenoma. Surgical exploration revealed the presence of a well differentiated PC. The patient was transiently normocalcemic, but underwent surgical exploration in 1993 and 1996 for recurrent PC in the neck. The patient again improved, but presented in 2001 with diffuse arthralgia, fatigue, malaise, weight loss, and decreased appetite. She was found to have a serum calcium of 12.7 mg/dL and an intact parathyroid hormone of 1542 pmol/L. Computed tomography identified the presence of two right-sided and two left-sided pulmonary masses. Sternotomy with bilateral pulmonary metastectomy was performed. Functional PC metastasis was confirmed on pathological examination. One year following metastectomy the patient is hypocalcemic, requiring oral calcium and vitamin D supplementation. Functional pulmonary metastasis from PC is a rare cause of hypercalcemia. Complete resection of isolated pulmonary metastases can provide effective palliation with long-term survival.

We describe a patient with hemangioma of the breast. The tumor showed an Ill-defined hypointense mass on T1-weighted imaging and hyperintense mass on T2-weighted imaging. After bolus gadolinium injection, the tumor showed heterogeneous enhancement in early phase and in the time-intensity an early intensive enhancement was followed by a plateau. This intensive enhancement in the early phase is not limited to breast carcinoma but can be found in breast hemangiomas as well.
