ABSTRACT

A 82-year-old man was found to have mucinous bronchioloalveolar carcinoma associated with a cavity 10-cm in size in the right lower lobe, and he underwent a surgical lobectomy in April 2005 (pT2N0M0). Seven months after the surgery, chest images showed multiple metastases with thick-walled cavities in bilateral lung fields. The serial HRCT showed that thick-walled cavity lesions transformed into thin-walled cystic cavities associated with decreasing serum CEA levels. The patient's condition was good with best supportive care for 24 months from the time of recurrence. Subsequent progression of the thick-walled cavities into thin-walled cavities, was acompanied by re-elevation of serum CEA levels, and he died of respiratory failure 5 months after re-exacerbation. Macroscopic findings at autopsy showed multiple cavities in both lungs. Microscopic findings of the right lung showed desquamative mucinous bronchioloalveolar carcinoma cells lining the thick-walled cavity surface, and a single layer of tumor cells proliferating in the thin-walled cavity surface. Tumor cells with excessive mucus and necrosis were observed in the thick-walled cavities. It is suggested that thick-walled cavities were formed as a result of avascular necrosis and destruction of the pulmonary alveoli by excessive mucus, and thin-walled cavities were formed as a result of a check-valve mechanism.

ABSTRACT

A 35-year-old woman underwent endometrial curettage for suspicion of miscarriage. A few minutes after intravenous injection of methylergometrin (0.2 mg) for inducing uterine contraction, blood gas analysis revealed severe hypoxemia. Chest CT showed diffuse ground-glass opacities in both lung fields and consolidation in the right lower lobe. Bronchoscopy revealed blood coagulation in the right bronchus intermedius. Bronchoalveolar lavage fluid showed fresh blood-like fluid containing hemosiderin-laden macrophages. We diagnosed pulmonary alveolar hemorrhage associated with pulmonary edema. Although we analyzed the possible causes of alveolar hemorrhage such as pulmonary thromboembolism, collagen disease, ANCA-related angitis and malignant disease, there were no underlying systemic diseases. It seems likely that contraction of the blood vessels caused by methylergometrin caused the increased pulmonary arterial and wedge pressure which led to pulmonary edema and alveolar hemorrhage. We believe this is the first reported case of pulmonary alveolar hemorrhage caused by methylergometrin, confirmed by bronchoscopy.

ABSTRACT

We report a case of malignant lymphoma arising from the testicle in a patient who had been on chemotherapy for a long period after orchiectomy. A 54-year-old male presented with indolent swelling in the right scrotum. Diagnosed as having a testicular tumor by ultrasonography and MRI, he underwent orchiectomy. According to the histopathological diagnosis, the tumor was classified as non-Hodgkin's lymphoma, diffuse large cell type, B cell type. Diagnosis of Stage I eA was made by the Arr Arbor classification. Four courses of cycrophosphamide, adriamycin, vincristin and prednisolone (CHOP) therapy were administered. COP (CHOP minus adriamycin) therapy has been given every four months on an out-patient basis. At present, 28 months after the operation, no evident recurrence has been found.

ABSTRACT

We have encountered 6 cases of urachal carcinoma in the past 7 years. They consisted of 4 females and 2 males, with the mean age of 48 years old. Of them, 2 cases were identified as gestational complications. Bladder irritating symptoms and extracystic symptoms other than hematuria were not observed as initial symptoms, and urinary cytology was positive in 2 cases. Cystoscopy is essential for diagnosis, but the spread of the tumor was clearly visualized by sagittal section patterns on magnetic resonance imaging. A correlation between the tumor and clinical course was suggested immunohistochemically with, carcinoembronic antigen and carbohydrate antigen 19-9. Cases of gestation concurrent with urachal carcinoma are very rare, but are expected to increase in the future. Thus appropriate medical treatment must be given to the maternal body. For the treatment, appropriateness of advanced surgery more than partial resection of the bladder combined with total urachoumbilical resection was recommended. However, an effective adjuvant chemotherapy after the first surgical resection needs to be established to improve the patient's quality of life.
