AbstractAbstract PDF
Temporal lobe epilepsy is characterized by complex partial seizures with either primary intracranial neoplasms or other non-neoplastic lesions. We reviewed 64 cases of surgically resected temporal lobes and amygdalo-hippocampal regions for temporal lobe epilepsy ansed by non-neoplastic lesions to elucidate the incidence and histologic features of each histologic group for a period of 2 years. The patient's age ranged from 12 to 49 years and the ratio of male to female was 42:22. There were 37 cases(57.8%) with single pathology and an additional 20 cases(31.3%) with dual pathology. The emaining 7 cases(10.9%) had no structural alternations. The most common temporal lobe pathology was hippocampal sclerosis in 41 cases(64.1%), diagnosed alone in 21 cases and as dual lesions in 20 cases. The hippocampal neuron loss was most pro,omemt in CA1, followed by CA4, CA3, and CA2. Amygdaloid sclerosis was present in 28 cases(43.8%), lases had 13 dual lesions, 25 cases also had hippocampal sclerosis. The 20 dual lesions showed that 6 cortical dysplasia, 10 microdysgenesis, 1 chronic non-specific inflammatory lesion, and 3 cysticercosis were associated with the various degree of mesial temporal sclerosis. Neuronoglial malformative lesions were identified in 21 cases(32.8%) including 16 dual lesion cases, which composed of 15 microdysgenesis and 6 cortical dysplasia. Neurofilament immunostain for cortical dysplasia revealed abnormally beaded disarray of axons in dysplastic pyramidal cells. The remaining pathologic lesions observed were 1 cysticercosis, 1 chronic non-specific inflammatory lesion, 3 arteriovenous malformation, 2 fibrous nodule, and 1 fibrous adhesions of the arachnoid.

AbstractAbstract PDF
Sixty one cases of gastric adenocarcinoma were studied immunohistochemically for expression of HLA-DR and secretory component(SC) in order to analyze the relationship between expression of these in gastric cancer cells and the adjacent mucosa. Immunostaining was detected within the cytoplasm and on the cell memgrane. The rate of HLA-DR and SC expressions in cancer cells were 59.0% and 49.2%, respectively, and 52.5%/52.5% and 31.2%/50.8% the mucosa in adjacent/remote from the site of to cancer. The SC expression in the adjacent mucosa was lower than that of the remote mucosa(p=0.027). The HLA-DR expression in the cancer cells in the intestinal type of gastric adenocarcinoma(73.9%) was higher than that of the diffuse type(14.3%) and it was statistically significant(p=0.02). The presence of an increased amount of lymphoid infiltration in the gastric mucosa was closely related to the expression of HLA-DR and SC. Decreased or absent expression of SC at the transitional mucosal cells was possibly a result of exposure to genotoxic agents due to the lack of protective function of SC-IgA. From these results, one can postulate that the expression of HLA-DR and SC may play an important role in atleration in microenvironment with lymphoid infiltration.

AbstractAbstract PDF
The clinicopathology of nine cases of eccrine spiradenoma was examined. The ages of the patients ranged from 32 to 65 years, with an average age of 46 years. There were four males and five females. Eight tumors out of the nine presented on the ventral surface of the upper body. The tumors were solitary in seven cases and multiple in two cases(cases 8 and 9). Six tumors were either painful or tender to palpation. Histologically, two cases(cases 1 and 2) were adenomas with well developed tubular structures, while the remaining seven cases were epitheliomas with poor organization and prominent reticular pattern. All tumors were composed of two distinct cell types. Since four cases showed considerable edema with a lot of cystic change, it was difficult in some areas to differentiate these from other adnexal tumors or vascular tumors. Immunohistochemical staining was performed on paraffin-embedded sections of 5 eccrine spiradenomas. CEA and EMA were expressed in the cytoplasm of tumor cells in all cases. Cytokeratin was expressed in 4 out of 5 cases, and S-100 in 3 out of 5 cases. There has been no evidence of recurrence in 8 cases. In one case(case 9) the tumor recurred locally with carcinomatous transformation- characterized by the presence of solid areas of tumor which was composed of large cells with irregularly shaped nuclei and mitotic figures. There were foci of ductal differentiation, extensive areas of tumor necrosis and invasion into surrounding connective tissue. The carcinomatous portion revealed positive reaction for CEA, EMA, S-100 protein and cytokeratin.

AbstractAbstract PDF
The polymerase chain reaction(PCR) was performed to detect clonal rearrangements of the immunoglobulin heavy chain gene(IgH) or T-cell receptor(TCR) genes in 57 lymphoproliferative diseases including 26 B-cell lymphomas and 23 peripheral T-cell lymphomas(PTCL). Using the IgH primers, monoclonality was detected in 19 out of 22(86.4%) cases of diffuse lymphomas and 2 out of 4(50%) follicular lymphomas, respectively, but not in the 23 PTCL cases. Using the V and J regions of the TCRgamma chain primers, monoclonality was detected in 14 out of the 23(60.9%) PTCL cases. TCR beta chain gene rearrangements were observed in 7 out of the 9 cases which did not show TCRgamma chain gene rearrangements. One non-T non-B acute lymphoblastic leukemia was found to have TCR beta chain gene rearrangements. In conclusion, analysis of Ig and TCR gene rearrangements by using the PCR technique can be used as a useful diagnostic adjunct to establish the clonality of various lymphoproliferative diseases.

AbstractAbstract PDF
Laryngeal leukoplakia is seen in a number of pathologic settings such as keratosis without atypia(KWOA), keratosis with atypia(KWA), squamous cell carcinoma in situ(CIS) and invasive squamous cell carcinoma, and it continues to be a confusing and controversial topic for both otolaryngologist and pathologist. This is largely due to the use of ambiguous and inconsistent terminology, the lack of unanimous agreement on the definition of these terms, failure of the clinician to obtain a representative biopsy, and the subjectivity of the pathologist interpreting the biopsy. To evaluate the applicability of the expression pattern of p53 and PCNA in borderline cases of histopathologic classification, we performed a histopathologic analysis of leukoplakia to includ clinical follow-up, correlation of disease progression and degree of atypia, and expression of p53 and PCNA according to the degree of atypia. Histologically, laryngeal leukoplakia included seven cases of KWOA, fourteen cases of KWA (mild-2, moderate-8, severe-4), three cases of CIS, and one case of invasive squamous cell carcinoma. Keratosis with atypia, a moderate degree or more, showed a strong tendency to progress to invasive carcinoma(p<0.05). The degree of p53 and PCNA expression correlated with the degree of atypia(p<0.05). p53-positive cases at the initial biopsy clearly tended to recur and develop into invasive carcinoma(p<0.01).

AbstractAbstract PDF
As measurement of glomerular size in the assessment of several renal diseases becomes increasingly important, it has become necessary to devise rapid simple methods for the assessment of glomerular size and to have on hand reference ranges. A few reports on glomerular size have been published in Western literature, but their body builds are different from Koreans. In this study, 100 glomeruli(50 glomeruli each from the outer cortical and the juxtamedullary area) were measured in sections taken from 74 kidneys(ages 3 days~73 years) obtained from autopsy utilizing the semi-automatic image analyser. The percentage of glomerular sclerosis was measured based on its location. The sphere diameter, maximum diameter, area and sphere volume of non-sclerotic glomeruli were measured and evaluated with respect to age, sex and the location of the glomeruli. The results were as follows; 1) Mean glomerular dimensions including sphere and maximum diameter, area and sphere volume increased until 40 years of age, then reached a plateau. The percentage of sclerotic glomeruli then increased slowly with age but without statistical significance. 2) The glomerular dimensions and sclerosis showed no significant differences according to sex. 3) Juxtamedullary glomeruli were larger than the outer cortical ones which was statistically significant in age groups of 0~10, 11~20 and 41~50 years. The percentage of sclerotic glomeruli was generally greater in the outer cortex. 4) Differences in the values of glomerular dimensions between outer cortical and juxtamedullary area were similar in all age groups. 5) All parameters of measurement showed consistent and similar trends between the different groups. 6) The measurements of the largest 12 glomeruli out of randomly-selected 50 glomeruli gave similar results when compared with those of 50 glomeruli. It was evident from our results that glomerular size is influenced by age and glomerular location, but not by sex. The method of assessing glomerular size used in this study will not necessarily give the true, absolute value of size but it may be a simple, practical and useful method of comparing glomerular size in different groups of patients.

AbstractAbstract PDF
Though trichogenic tumors were classified as trichoblastoma, trichoblastic fibroma, trichogenic trichoblastoma and trichogenic myxoma by Headington(1970), their true classification depends upon the epithelial and mesodermal component as well as evidence of their induction. Because of the rarity of hair germ cell tumors their classification is still controversial. In this report, we describe a case of trichogerminoma which is not included in the above classification. The trichogerminoma was first described by Sau et al. in 1992 and characterized by its morphologic pattern of germinal centers and lymphoid follicle-like structures in the nests of trichoblasts. Herein we reporte a tumor which arose on the skin on the back of a 51-year-old man and presented as a sharply circumscribed mass(4.5x2.0x1.5 cm) involving both the dermal and subcutaneous tissues without any epidermal connection. The tumor had many germinal center-like structures in the basaloid trichoblasts. Lobular cell nests were separated by variable amounts of stroma, but no horn cyst were noted. The germinal center-like cells showed early differentiation of hairs, resembling early hair bulbs. Trichogerminoma is considered to be a type of tumor located between trichoblastoma and trichoblastic fibroma.

AbstractAbstract PDF
Angiomyofibroblastoma is a distinctive, hitherto uncharacterized, benign soft tissue tumor of the vulva with histology similar to an aggressive pelvic angiomyxoma. It can be distinguished from an aggressive angiomyxoma by its circumscribed borders, higher cellularity, more numerous blood vessels, the frequent presence of plump stromal cells, minimal stromal mucin, and rarity of erythrocyte extravasation. We experienced a case of angiomyofibroblastoma of the vulva occurring in a 45-year-old woman. The lesion was a well-defined but not encapsulated mass, 4.5x4.2 cm. Histologically the mass was characterized by alternating hypercellular and hypocellular edematous zones in which abundant blood vessels were irregularly distributed. Immunohistochemically, the spindled, plump spindled, and oval stromal cells were reactive for vimentin and desmin, but not for cytokeratin, or S-100 protein.

AbstractAbstract PDF
We report a case of secretory carcinoma with axillary lymph node metastasis in a 21-year old woman. She was aware of a mass in her breast for 10 years and noticed a rapid growth of the preexisting mass during the last years. Histologically, the tumor was composed of micropapillary and microcystic or cribriform glandular structures which contained eosinophilic, mucinous, intraluminal secretions. The center had a dense hyalinized strama with a solid infiltrative growth of tumor cells with intracytoplasmic secretory vacuoles at the periphery. In addition, marked intraductal papillary epithelial proliferations were present at the superficial portions of the tumor near the nipple. Prognostic factors and their relationship to juvenile papillomatosis are discussed with a review of the literature.

AbstractAbstract PDF
Classic pulmonary blastoma is a variant of carcinosarcoma which is seen almost exclusively in adults. By contrast, most cases of pulmonary blastoma in children have been described as having an exclusive mesenchymal composition, which was proposed as pleuropulmonary blastoma. Recently we experienced a case of pleuropulmonary blastoma, type 1. This 27-month-old male baby was transferred to our hospital due to the left tension pneumothorax. Chest CT revealed a subpleural pulmonary cystic lesion on the left upper lung and an open cystectomy was performed. Histologically the lesion was composed of variable-sized cystic structures lined with a single layer of respiratory-type epithelium. the underlying stroma was composed of sheets of small, round to oval, primitive tumor cells. Some of them had eccentric, eosinophilic cytoplasm, suggestive of rhabdomyoblastic differentiation. These rhabdomyoblastic cells were fuchsinophilic and positive with desmin and vimentin on immunohistochemistry.

AbstractAbstract PDF
Adrenal pseudocysts are uncommon lesions which usually occur as a result of hemorrhage within the adrenal tissue. Adrenal hemorrhage is usually associated with severe stress, sepsis, pregnancy, syphilis, leukemia, or anticoagulant therapy but during steroid therapy, it is very rare. We report a case of adrenal pseudocyst that resulted from hemorrhage into the adrenal gland and is probably related to the exogenous administration of steroids. The patient was a 57-year-old woman who was treated with oradexon for 20 years for the treatment of a maculopapular lesion on her thigh as well as for arthritis. She underwent a right adrenalectomy due to the adrenal cystic mass. The wall of the cystic mass was composed of a thick layer of hyalinized fibrous tissue with remnants of adrenal cortical tissue on the outer aspect. The inner surface had no lining cells and the wall of the cyst contained many calcified plaques with hemosiderin pigment.

AbstractAbstract PDF
Chromomycosis is a chronic cutaneous fungal infection characterized by the presence of dark brown parasitic forms of fungi in biopsied tissues. It is usually resulted from the entry of the causative organism through a minor trauma, and therefore, most lesions are found on the exposed part of the body, such as limbs or face, and occurrence on the nasolacrimal duct is extremely rare. We report a case of chromomycosis of the right nasolacrimal duct, which was presented with clinical symptoms of nasolacrimal duct obstruction. The patient was a 40 year-old male who had had minor injuries on his left eye twice by paper and branches of the tree two months prior to epiphora in right eye. On dacryocystorhinostomy, right nasolacrimal duct was obstructed by pinkish brown mucoid ball. Microscopically, the mucoid ball revealed eosinophilic, amorphous, necrotic materials admixed with brown pigmented fungi. The organism showed characteristic dark brown, round, thick-walled, often septated, sclerotic bodies and brown pigmented long bead-like hyphae. The adjacent mucosa shows marked chronic nonspecific inflammation with fibrosis.

AbstractAbstract PDF
Giardiasis is one of the most common causes of infectious diarrhea and it has a worldwide distribution. Although it is a relatively common disorder, histologically confirmed Giardiasis is a rare occurrence and there have been no previous reports in Korea. A 34-year-old man presented with a 2-year history of epigastric discomfort and left flank pain. On stool examination, many cystic forms of Giardia lamblia were noted. In biopsy specimens of the small intestine, there was moderate chronic inflammatory cell infiltration and several trophozoites of Giardia were observed in the intervillous space and luminal surface. The trophozoites were pear shaped symmetrical organisms with two nuclei, and measured 9~10 micrometer in length.
