1.Ultrastructural Feature of Molluscum Contagiosum Virus.
Korean Journal of Pathology 1995;29(3):321-326
Molluscum contagiosum virus(MCV) infection occurs in both sporadic and epidemic forms, and affects children more frequently. The skin lesions are small, pinkish and wartlike tumor. MCV has not been transmitted to animals and nQt propagated in cell culture. Therefore the viruses in human lesions can only be demonstrated by electron microscopy. Histologically, characteristic intracytoplasmic inclusion bodies (called molluscum bodies) are formed in infected epithelial cells. They gradually enlarge and eventually fill the cell. Ultrastructure of molluscum bodies in infected cells showed a large number of MCV particles that are variable-sized, spherical, ellipsoidal and brick-shaped. Early viral replication stage shows small dense bodies in the nucleus and then reveal immature MCV that consist of homogeneous rounded core and separated capsidal membrane from the cytoplasm matrix In advanced stage, shrinked nucleus with irregular membrane moves into marginal area of the cell. The spherical fon-ns represented immature viruses in cytoplasm matrix, whereas the brick-sphaped forms represented mature viruses in the inclusion of cytoplasm.

2.Ultrastructural Observation on Maturation Process of Cytomegalovirus in Human Cells.
Korean Journal of Pathology 1994;28(5):478-484
Cytomegalovirus(CMV) infection can be diagnosed by finding characteristic intranuclear inclusion body and enlargement of the cell size congenital CMV infection can be associated with various types of anomalies seen in different gestational age. These anomalies are probable due to direct virus infection of the parenchymal cell m early gestation. Based on four autopsy cases of congenital CMV infection we have studied maturation process of virus particles in parenchymal cells, with special reference to me mode of replication and transmission. Virus particles in CMV-infected cells in brain and kidney showed nucleocapsids with characteristic concentric core, that were enclosed around fibrillar network in nucleus. During replication process virions showed various morphogenic mutation that was rather consistent in different tissues and individuals. There were virions without core or with eccentric core. Occasional cores were divided into 2~5 fragments. The virus particles reached the cytoplasm through the nuclear membrane, and here the virions increased twice in size. After virions were fully matured in the cytop1asm. they showed exocytosis phenomenon through the cellular membrane to reach extracellular portion.

3.Primary Ciliary Dyskinesia(Immotile Cilia Syndrome): Clinical and electron microscopic analysis of 17 cases.
Korean Journal of Pathology 1993;27(2):99-107
Immotile cilia syndrome is a genetically determined disorder characterized by immotility or poor motility of the cilia in the airways and elsewhere. Since its first description in 1976 determination of a ciliary abnormality has now clarified its variable expression and pleiotropism. Certain specific defects in the ciliary axoneme can be found and are pathognmoic of the syndrome. These defects include missing dynein arms, abnormally short dynein, arms, spokes with no central sheath, missing central microtubules, and displacement of one of the nine peripheral doublets. We have studied 80 cases of bronchial or nasal mucosal biopsies that were performed with the suspicion of immotile cilia syndrome. Of 80 cases only 17 cases were sampled optimally to be able to observe under transmission and scanning electron microscopes. All 17 cases had certain abnormality of the cilia. They consisted of Ia(3 cases), Ib(3 cases), Id only(3 cases) and Id+other types(6 cases) a according to Sturgess classification. Seven cases consisted of 1 solitary and 6 combined form; II+Id(1 case) and II+Id+III(5 case). All 5 cases of type III were combined with Id and II. Clinically most pronounced manifestations were cough(82%), sputum(59%), rhinorrhea(41%) and nasal stuffiness(35%), All the patients were below the age of 15 years, and there were 6 boys and 11 girls.

Scanning electron microscopic(SEM) examination of hair is an efficient and definite method for the diagnosis of hair anomaly. The Hair specimen is placed on a stub, gold coated, and directly viewed without prior fixation or treatment for identification. We have analyzed 25 cases of scalp hair and 2 cases of eyebrow that were sampled with the suspicion of hair anomalies at Seoul National University Hospital during the last 7 year period from January 1988 to June 1992. All 27 cases had certain abnormalities of the hair. They consisted of monilethrix(1 case), hair casts(4 cases), pili torti(1 case), uncombable hair syndrome(1 case), trichorrhexis nodosa(5 cases), woolly hair(5 cases) and other anomaly(1 case). Some cases of them were mixed with two or three anomalies in hairs. Their combinations were; hair casts and woolly hair(1 case), hair casts and pili torti and uncombabla hair syndrome(1 case), hair casts and uncombable hair syndrome and trichorrhexis nodosa(1 case), trichorrhexis nodosa and uncombable hair syndrome(3 cases). Most of these defects included brittleness of scales and distortion of the hair shaft.

We report a case of multiple Bowen's disease associated with leprosy. A 68-year-old man was seen because of slightly pruritic multiple erythematous scaly patches and plaques on the trunk and the both extremities for 5 years. He has been treated for leprosy with many kinds of drugs consisting of the herb medications for over 40 years. He also showed decreased cell-mediated immunity in skin tests. It is considered that depressed cellular immunity may be an important predisposing factor in the development of mutiple Bowen's disease in this case, .although arsenics can not be completetly excluded.

Male breast cancer is a rare disease, representing approximately 1% of breast cancer and less than 1.5% of malignant tumors occurring in men. We report a case of cuaneous metastasis of male breast cances. a 64-year-old male who presented with multiple nodules and erythematous plaque on the right anterior chest and enlargement of the right axillary lymplinodes. The histopathologic findings of the nodule showed atypical tumor cells with a somew eat gland-like pattern. The cells showed potive reactions in PAS, DPAS and alcian blue stains, and also positive for estrogen and roiesterone receptors. Biopsy specimens taken from the plaque showed cellular arrangement in show line, referred to as Indian filing, between thiclenecin collagen bundles. He was treated not, tamoxifen, 5-fluorouracil, adriamycin, cyclophosphamide and megestrol acetate. 5 months after nitiation of the treatment, the skin lesions were improved vvith a decreased number and size or dules and decreased intensity of erythema.

A 31-year-old woman had a livedo reticularis of reticulated, bluish discoloration on both arms and legs for 18 months with a burning pain in the right hand and numbness in both lower legs. The findings of the electromyography were consistent with mononeuropathy multiplex and bilateral ulnar-median nerve anastomosis. A biopsy specimen from the right sural nerve showed perivascular lymphocytic infiltration and occasional myelin digestion chambers, which were consistent with vasculitic neuropathy. We present a patient with livedo reticularis idiopathica associated with mononeuropathy multiplex syndrome who also has bilateral ulnar-median nerve anastomosis.

Urethral injury studied from Jan. 1976 to Jun. 1980 at Department of Urology, Busan National University Hospital was reviewed respectively with particular attention to etiology, diagnosis and operative procedure. During the period total number of patients with urethral injury was 104, of whom 67 were anterior urethral injury and the remaining 37 were posterior urethral injury. The following results were obtained. 1. The rate of the urethral injury to genitourinary tract was 49. 5 per cent. 2. In anterior urethral injury, the most common cause was industrial accident, the mode of injury was straddling. In posterior urethral injury, the most common case was traffic accident, the mode of injury was blunting. 3. According to the result of treatment in anterior urethral injury, Foley catheter indwelling was not effective in about half cases, but good results were by modified Badenoch`s pull-through urethroplasty just after injury or after long-term cystostomy. In posterior urethral injury, we had poor results with primary realignment just after trauma, but good results with classic Badenoch`s pull-through urethroplasty after long-term cystostomy.

We report an extremely rare case in which two tuberculids, papulonecrotic tuberculid and erythema nodosum, occurred together. A 16-year-old girl had two types of clinically distinct lesions; asymptomatic necrotic papules on the upper and lower extremities and painful subcutaneous nodules on the legs. A Mantoux test showed a strong positive reaction. Histopathologic findings of the necrotic papule and subcutaneous nodule were consistent with papulonecrotic tuberculid and erythema nodosum, respectively. There was no extracutaneous focus of tuberculosis. Polymerase chain reaction for tuberculous bacilli in the papulonecrotic tuberculid lesion revealed a negative result. Antituberculous therapy brought a rapid clinical improvement of both lesions.
