A case of hepatic fascioliasis misdiagnosed as metastatic carcinoma was reported. The patient was a 22-year-old woman who had had rectal adenocarcinoma (Duke stage C2), and had been treated by Mile'operation 8 months ago. A computed tomogram(CT) demonstrated multiple low density nodules in the liver suggesting a metastatic tumor. A partial liver lobectomy was performed. The resected liver showed multiple necrotic nodules, which appeared to be abscesses containing eggs of the Fasciola species. Parasitic infection should be considered as one of the possible etiologies of hepatic nodules which mimic metastatic carcinoma either clinically or radiologically.

Apocrine carcinoma is a rare type of mammary cancer, which shows partial or total apocrine differentiation in either ductal or lobular carcinoma. The malignant transformation of apocrine epithelium of the breast was first described by Krompecher in 1916. It is well known that their relationship to true apocrine glands of the skin is only a morphological similarity, and this histological difference does not affect the prognosis. The authors experienced two cases of apocrine carcinoma of the breast which involved infiltrating ductal carcinoma of a 64-year old woman and intraductal carcinoma of a 69-year old woman respectively. Electron microscopic examination and brief review of literature was done.

An analytic study on 431 cases of cardiac conduction disturbance has been made by review of the clinical records and electrocardiograms taken from the adult patients registered at Kyung Hee University Hospital for 3 years from May, 1973 to April, 1976. 1. The total incidence of conduction disturbance was 6.50%, the atrioventricular block 3.14% and the intraventricular block was 3.36% of total 6,616 cases of E.C.G. reviewed. Among of these, the first degree atrioventricular block was 3.02% which was the most common occurred one, the incomplete right bundle branch block was 2.25% and the complete right bundle branch block was 0.57%. 2. The ratio of male to female was 1.6:1 for the first degree atrioventricular block, and 1.6:1 for the incomplete right bundle branch block, 2.5:1 for the complete atrioventricular block, 2:1 for the left bundle branch block, and 1.7:1 for the complete right bundle branch block. The first degree atrioventricular block was seen most frequently in the fifth and sixth decade of age group, and the third degree block was over 40 years. The incomplete right bundle branch block in order was forth decade, third decade and fifth decade. The complete right bundle branch block and left posterior hemiblock were common in the sixth decade. The left bundle block and the posterior hemiblock were common in fifty years of age group. 3. The cardinal underlying diseases of the first degree atrioventricular block among cardiac diseases group in order of frequency were: hypertensive heart disease (25.0%) arteriosclerotic heart disease (8.0%) and rheumatic valvular heart disease (5.0%). The most common etiology of those non-cardiac disease group was neuropsychiatry disorder (11.5%) and the next was infection (11.0%). 4. All of the complete atrioventricular block were associated with the cardiac disease, that is, 57.0% with arteriosclerotic heart disease, 28.5% with pericarditis and 14.3% with hypertensive heart disease, respectively. 5. The cardinal underlying disease of the incomplete right bundle branch block in order of frequency were: hypertensive heart disease (10.7%), arteriosclerotic heart disease (8.1%) among the cardiac disease group, and infections (15.4%) among the non-cardiac disease group. The incidence of healthy persons was 14.1%. 6. Those of complete right bundle branch block in order of frequency were: arteriosclerotic heart disease (13.2%), and hypertensive heart disease (10.1%) among the cardiac disease group, and infection(13.2%) and neurosis (10.1%), respectively among the non-cardiac disease group. 7. The major etiologies of the left bundle branch block was hypertensive heart disease and arteriosclerotic heart disease (33.3% each), and that of left posterior hemiblock was showed arteriosolerotic heart disease and cor-pulmonale. The most common etiological disease of the left anterior hemiblock was hypertensive heart disease in cardiac disease group, and infection and gatrointestinal disease in non-cariac disease group. 8. The abnormal electrocardiographic findings with the first degree atrioventricular block were left ventricular hypertrophy (24.8%), sinus tachycardia (11.0) and sinus bradycardia (5.8%). Those with the complete atrioventricular block were right ventricular hypertrophy (15.8%) and left bundle branch block (15.8%). In complete right bundle branch block, the majority (52.5%) showed single sign without other abnormality on E.C.G. In the left bundle branch block, there were 18.9% of left ventricular hypertrophy and 15.7% of first degree atrioventricular block. In the left anterior hemiblock, there were 28.5% of right bundle branch block, and 19.0% of right ventricular hypertrophy. In the left posterior hemiblock, there were 40.0% of atrial fibrillation and 20.0% of left atrial hypertrophy.

Inadvertent application of ionizing radiation, a valuable tool in diagnostic radiology and radiotherapy, results in injury and death of adjacent normal cells, inducing gene mutations or even producing latent cancers. Captopril, an angiotensin I converting enzyme (ACE) inhibitor, has been reported to prevent the structural and functional changes in variable organs, such as lung and kidney, from radiation injury in different experimental animal models. An experiment was carried out to elucidate the radiation-induced histomorphologic changes of small intestine, especially jejunum, and to determine whether captopril can reduce or prevent the radiation-induced injuries in jejunum. Twenty-six healthy Sprague-Dawley rats were used. Experimental group (n=24) was divided into two large groups: the first one (n=16) was treated with two different single dose (9 Gy, 17 Gy) irradiation only and was sacrificed at 12 hours and at 8 weeks following irradiation; the second one (n=8) received captopril 500 mg/l per oral continuously after same doses of irradiation and was sacrificed at 8 weeks. The control group (n=2) was maintained on a stock diet in a same period of experimental group and sacrificed coincidentally. On light and electron microscopy, the 9 Gy and 17 Gy 12 hours groups revealed frequent apoptosis and necrosis but extremely decreased mitotic figures of the crypt cells. However, the 9 Gy and 17 Gy 8 weeks groups and the combined irradiation with captopril groups showed extremely reduced apoptosis and necrosis with increased mitotic figures. There was good correlation between experimental groups in apoptotic count and mitotic count (p<0.05). In the 9 Gy and 17 Gy 12 hours groups, the mucosal surface was focally or diffusely fragmented and the villi were slightly to moderately distorted. Collagen deposition was very mild and confined to the lower portion of the lamina propria. The 9 Gy and 17 Gy 8 weeks groups showed more severe mucosal surface fragmentation even with foci of erosion, short and distorted villi, and more intense collagen deposition. In contrast, the combined irradiation with captopril groups revealed complete regeneration of the mucosal surface epithelium and absent collagen deposition. These findings suggest that the acute radiation injuries to small intestine occur principally in the mucosal crypt cells. Captopril, the ACE inhibitor, might provide a useful intervention in the radiation injuries of intestinal mucosa.

PURPOSE: In this study we investigated the histopathologic characteristics of conjunctivochalasis and its association with lymphangiectasis using impression cytology and conjunctival excisional biopsy in patients with conjunctivochalasis. METHODS: This prospective study included 14 outpatients diagnosed with conjunctivochalasis, and who had excisional biopsies performed between March 1, 2012 and November 30, 2012. Preoperative slit-lamp examination, dry eye diagnostic test and impression cytology were also performed. For histological analysis, conjunctival sections were stained with hematoxylin and eosin (H&E), Verhoeff-van Gieson (VVG) elastic staining, and monoclonal antibody D2-40, a lymphatic endothelial marker. RESULTS: Tear break-up time and Schirmer's value were decreased in patients with conjunctivochalasis. Impression cytology showed a decrease in goblet cell density and an increase in nucleoplasmic/cytoplasmic ratio. The patients' conjunctival tissues exhibited an infiltration increase of chronic inflammatory cells on H&E stain, and a decrease in collagen density with degeneration of elastic fibers on VVG stain compared to tissues from the control subjects. D2-40 immunohistochemistry revealed the dilated subconjunctival lymphatics in patients with conjunctivochalasis. CONCLUSIONS: This study suggests that the characteristic histopathological features of conjunctivochalasis include dilated lymphatic vessels as well as decreased goblet cell and collagen densities with degeneration of elastic fibers.

We herein present a case of bullous lichen planus in a 56-year-old female. She had had a generalized eruption of lichen planus with violaceus papules and plaques. many of which had been surmounted by vesicles and bullae. The histopathologic findings of a bulla revealed hyperkeratosis, irregular acanthosis, subepidermal bulla and upper dermal band-like cell infiltration. The patient had been treated with dapsone but the lesions had not been significantly improved.
