Fourteen cases of bowenoid papulosis were studied both clinically and histologically and were compared with 22 cases of Bowen's disease to find histologic differences between the two diseases. Bowenoid papulosis was prevalent in young, sexually active adults, consisted of multiple erythematous or hyperpigmented papules, and located mostly on the penis and vulva. The main histologic characteristics of bowenoid papulosis were an orderly background of keratinocyte maturation of the epidermis with monotonous pattern, the frequent presence of 'skip area', and the lesser degree of cytologic atypia than seen in lesions of Bowen's disease. In addition, mitotic figures more than 5 per x400 filed, formation of keratin pearl, and spindling of keratinocytes, which have not been described in other articles yet, are considered very important findings for the diagnosis of bowenoid papulosis. It is our opinion that bowenoid papulosis can be reliably distinguished from Bowen's disease by light microscopic features. Paraffin-embedded samples of bowenoid papulosis, Bowen's disease, and normal skin were investigated with antibodies against S 100-protein to relate the number of intraepidermal Langerhans cells and the disease. Langerhans cells were found to be reduced when compared with normal skin. No significant differences between Bowen's disease and bowenoid papulosis were found in density of Langerhans cells.

The capillary hemangioblastoma, as originally defined by Lindau and by Cushing and Bailey, is widely regarded as being of Vascular origin and relatively uncommon. The most frequent site of this neoplasm is the cerebellum and second frequency is the spinal cord. We experienced a case of capillary hemangioblastoma arising at the upper thoracic spinal cord with the paraplegia and the sensory disturbance below the nipple line. The total laminectomy with mass excision was taken and the patient have shown good improvement of the neurological defecits in postoperative period.

The purpose of this study was to investigate that there was any differences of uptake ratio of Tc99-m-MDP during the healing process related to fracture level in tibia. Thirty mature rabbits were devided into three groups and each group consisted of ten rabbits. The osteotomy was performed at the proximal third of tibia in group I, at the middle third in group II and at the distal third in group III, respectively. After fracture was reduced, the fractured tibia was fixed with K-wire and immobilized with long leg cast. Serial Tc-99m-MDP scintigraphy with pixel counting method was performed in thirty cases of tibial shaft fracture from one day to eight weeks after fracture. The results obtained were as follows: l. In group I, the mean uptake ratio of Tc-99m-MDP at fracture site was 1.40±0.45 at two days after fracture, 3.34±1.21 at two weeks and increased rapidly to a maximal value of 7.51%1.01 at three weeks and decreased thereafter to 4.530.83 at eight weeks. 2. In group II, the mean uptake ratio was 1.10±0.10 at three days, 3.931.±10 at three weeks and increased rapidly to a maximal value of 7.37±2.21 at four weeks and decreased thereafter to 4.54±0.96 at eight weeks. 3. In group III, the mean uptake ratio was 1.13 ± 0.11 at three days, 3.95±0.93 at three weeks and increased rapidly to a maximal value of 7.43±1.72 at four weeks and decreased thereafter to 4.69±0.93 at eight weeks. These experiments suggest that the changes of Tc-99m-MDP scintigraphy in the proximal third fractures of tibia was earlier than middle or distal third fractures and there was no differences between middle and distal third fractures of the tibia.

A 43-year-old male patient visited our clinic complaining of persistent erythematous skin eruptions on the anterior chest, abdomen, and back for 10 years. Reticular erythematous mucinosis (REM) syndrome was diagnosed by the clinical and histopathologic features. Mucin deposition is much more conspicuous in papular lesions than in plaque lesions. Therefore, we suggest that the papular lesions may show the characteristic changes of REM and that a biopsy specimen should be obtained from a papular lesion for proper diagnosis of REM syndrome.

After simple clcsure of duodenal ulcer perforation under general anesthesia on a 34 year old male patient, atelectasis developed, Oo the 2nd postoperative day, dyspnea suddenly developed and atelectasis was confirmed by chest X-ray. Tracheostom,y was performed, and I.P.P.B. and suction were continued for a few days. The patient was discharged without further event.

This is to describe a neonatal hepatitis with pericellular hepatic fibrosis and Mallory bodies in a sero-positive infant for IgM anti-CMV. A necropsy of the liver revealed severe heaptocellular swelling with many intracytoplasmic hyaline bodies, pronounced fibrosis of a creeping type, bile stasis with ductular proliferation, and the lack of parenchymal regeneration. These microscopical changes of the liver resembled those of Indian Childhood Cirrhosis (ICC). In the present case the patient's serum IgM anti-CMV is the only clue for the etiological diagnosis.

Strongyloides stercoralis is a nematodes and is prevalent in the tropical regions. In Korea, 6 cases have been reported in which the parasites were identified in feces. We report a case of hyperinfection syndrome with Strongyloides stercoralis confirmed in the tissue sections. A 52-year-old woman was admitted to the hospital because of generalized edema and weakness. She received steroid therapy for 30 years because of rheumatoid arthritis. One year ago, generalized edema and dyspnea were developed and she was diagnosed as minimal change nephrotic syndrome for which she received cyclosporin. On admission, she complained of generalized weakness and edema, multiple arthralgia and abdominal discomfort with nausea. The white-cell count was 14,600 without eosinophilia. A stool specimen was negative for occult blood, ova or parasites. Right lower quadrant abdominal pain and tenderness were developed, and the exploratory laparotomy was done under the impression of the acute appendicitis. An appendectomy with a biopsy of mesenteric lymph nodes was performed. From the 5th day after operation, the patient began to complain of the abdominal pain and constipation. Under the impression of adhesion bad formation, the laparotomy was done and disclosed that the proximal ileum was markedly dilated. On jejunotomy, a great amount of formed stool and barium was noticed in the proximal portion of small bowel. The jejunal tissue was biopsied. Grossly, the appendix was unremarkable. Microscopically, the inflammatory reaction was nearly absent, but in serosa, minute granulomas were found which contain a part of the parasite. Same feature was noted in the mesenteric lymph node. The biopsied jejunum contains numerous adult female, filariform and rhabdidiform larvae and eggs in the mucosa, submucosa and muscle wall. Their morphology was compatible with Strongyloides stercoralis. The patient died 5 days later in the state of multiple organ failure.

Astrocytes are the most numerous cellular elements in the cerebrum, and they normally have a very slow turnover rate. But during regeneration after injury, they proliferate markedly resulting in astrogliosis. The extracellular matrix in the central nervous system is present in the vessel walls and in the external glia limitans as a basal lamina. The presence of an intact extracellular matrix framework is important in regeneration after injury. Understanding the properties of astrocytic proliferation will be helpful to find out new treatment for functional recovery in the central nervous system. In this study, after cryogenic injury was performed on the cerebral cortex in rats, changes in astrocytes and the extracellular matrix were observed using light microscopy, immunohistochemical stain for glial fibrillary acidic protein(GFAP), proliferating cell nuclear antigen(PCNA), fibronectin, laminin, and type IV collagen, autoradiography and electron microscopy. The results were as follows; 1) The coagulative necrosis, which followed cryogenic injury on the cerebral cortex was healed, forming a new pia mater above the lesion. 2) Some of the PCNA positive cells were astrocytes and some of the GFAP positive cells showed a positive reaction to PCNA. 3) Proliferating astrocytes labelled by autoradiography or immunohistochemical stain for PCNA reached maximal numbers 3days after the injury and they were no longer found 2 weeks after injury. 4) In autoradiography with immunohistochemical stain for GFAP, about 1% of GFAP positive astrocytes were labelled by autoradiography and in double immunohistochemical stain for PCNA and GFAP, about 8-16% of GFAP positive astrocytes were also stained by PCNA. 5) In immunohistochemical stain for fibronectin, laminin and type IV collagen, laminin and type IV collagen were present in the newly formed blood vessel walls and fibronectin showed a diffuse positive reaction within the lesion. The new pia mater was formed within 2 weeks after the injury. 6) On electron microscopic examination, basal lamina material was found in the vessel wall 1 week after the injury and at 2 weeks, a nearly complete and continuous basal lamina was formed although the thickness was uneven. According to these findings, astrocytes in the cerebral cortex of adult rats proliferate very early in the regenerative period after cryogenic injury. At 2 weeks after the injury, this regeneration ceases and the damaged basal lamina of pia mater and vessel wall were reconstituted.
