During 1964 to 1967, a survey of 30,534 persons for filariasis was made on all over the country with the following results: Among 24,816 draftees from all over the country in the army recruitment camp 155(0.63 %) were found infected with Brugia malayi. Cheju Do showed the highest microfilaria rate(3.5 %), North Kyongsang Do(1.4 %) the next and South Cholla Do(1.2 %) the third. Blood films from 2,308 inhabitants were examined and 407(17.6 %) showed microfilaria in Cheju Do. 30(3.1 %) out of 974 inhabitants in North Kyongsang Do were found to be infected. The microfilaria rates were 2.0 per cent for 400 inhabitants of Chindo island in South Cholla Do. However, no positive case of microfilaria was found in the inhabitants of Kokumdo among 1,820 persons examined in South Cholla Do and of Namhae island(among 165 persons examined) in South Kyongsang Do. The mean microfilarial density per 20 cu. mm of blood was 52.6 in the inhabitants of Cheju Do, 12.2 in North Kyongsang Do and 27.3 in Chindo island(South Cholla Do). Any distinct relationship between the incidence of positive cases of microfilariae and age or sex of the cases was not observed in Cheju Do. However, in Norh Kyongsang Do and South Cholla Do the microfilaria rate of the male group is higher than the one of the female group of the inhabitants. From the above survey results it turned out that filariasis was found throughout Southern Korea except Kyonggi Do and South Kyongsang Do. A total 30,534 persons examined, 601(2.0 %) were found to be infected by Brugia malayi. Therefore, it seems that there are some endemic foci of malayian filariasis in three main areas such as North Kyongsang Do, South Cholla Do and Cheju Do.

Intracranial teratomas are diagnosed mostly in young population and usually involve midline structure. We report a case of mature teratoma in an adult patient with unusual location in cerebellar hemisphere. A 47-year-old woman presented with severe headache and nausea. Computed tomography and magnetic resonance imaging demonstrated a posterior fossa lesion with cerebellar hemispheric location not involving midline. Histological examination of surgical specimen showed fully matured representative tissues of the three germ layers confirming teratoma. This is a rare example of mature teratoma with unusual age of the patient and location.

Fluoroscopy-induced chronic radiation dermatitis (FICRD) is a cutaneous disorder that results from prolonged exposure to ionizing radiation during interventional procedures. With the expanded use of interventional procedures, there is increased fluoroscopic exposure. However, diagnosis and treatment of such disorder remain difficult. Herein, we report on a case of FICRD that occurred in the right subscapular area.

In the development of a cancer, unlimited cell proliferation has been believed to play an important role. In addition, a programmed cell death called apoptosis, which is regulated by several oncogenes and tumor suppressor genes, has been suggested to be another important different pathway of carcinogenesis. Recently, several reports on cell proliferation capacity and apoptosis in the development of human liver disease have been published, but the cell proliferation index and its relationship between the expression of the bcl-2 and p53 genes involving apoptosis has not yet been discussed in view of the clinical differences of primary and metastatic liver cancer. In this study, we investigated the cell proliferation index and expression of p53 and bcl-2 in the tumorous and non-tumorous portions of both hepatocellular carcinoma and metastatic liver cancer. The expression of p53 was observed in both hepatocellular carcinoma and metastatic liver cancer, but bcl-2 expression was observed neither in hepatocellular carcinoma nor in metastatic liver cancer. In hepatocellular carcinoma, the p53 positive group showed a higher Ki-67 score (cell proliferation index) and more tumor numbers than the p53 negative group (p<0.05). In metastatic liver cancer, the results were the same as in hepatocellular carcinoma (p<0.05). However, we could not correlate the p53 expression and its prognostic significance in hepatocellular carcinoma.

Balloon cell melanoma, an uncommon histopathological variant of malignant melanoma, was first described by Gardner and Vazquez in 1970. This condition is histopathologically characterized by the presence of balloon cells with varying sizes and atypical nuclei. An 84-year-old woman presented with a solitary, dome-shaped, walnut-sized, brownish nodule on the posterior aspect of the left ear with bleeding, having only detected the nodule 2 weeks prior. Histopathologically, the lobulated tumor mass revealed copious melanin pigment and many balloon cells with clear cytoplasm, atypical nuclei, and variable size. Immunohistochemically, the tumor mass showed positive reaction to S-100 protein and HMB 45 staining. We herein report a typical case of balloon cell melanoma, which developed primarily on the skin.

Chronic mucocutaneous candidiasis is a rare syndrome characterized by persistent and refractory infection of the skin, nail and mucosal tissue by yeasts of the genus Candida. A 70-year-old woman presented with the following skin lesions: ill-defined annular shaped whitish macules on the upper and lower lips accompanying dryness, pain and burning sensation, and yellowish discoloration with onycholysis of the right 4th finger nail. The upper lip lesion showed histopathologic feature of band-like infiltration of lymphocytes in the upper dermis, consistent with lichen planus. But, systemic glucocorticoid was not effective in treating erosive lip lesions. KOH examination and fungal culture of specimens from the upper lip showed hyphal elements and growth of Candida albicans, respectively. Antifungal agent was administered. After the oral medication, skin lesions were improved but there was repeated recurrence. We report a case of chronic mucocutaneous candidiasis misdiagnosed as lichen planus.

BACKGROUND: The histologic distinction of dermatofibrosarcoma protuberans (DFSP) and dermatofibroma (DF) may be difficult, especially in the case of DF extending into the subcutaneous fat. CD34 and Factor XIIIa stains are commonly used in distinguishing the DF from DFSP, but is not always helpful. There are no studies regarding the clinicopathologic comparison of DF and DFSP. OBJECTIVE: The aim of our study was to evaluate the clinicopathologic characteristics and differences between the DF and DFSP. METHODS: Retrospective analysis was performed by reviewing the clinicopatholgic records of 40 patients who were diagnosed with DF, and 11 patients who were diagnosed with DFSP, from 1998 to 2012 in Hallym University Medical Center. RESULTS: The ratio of male to female patients in DF and DFSP were 1:2.1 and 1:1.8, respectively. Disease onset ages were 32.6 years and 34.4 years, respectively. The average size was 0.8 cm and 2.0 cm, respectively. The most frequent location was the lower extremity and the trunk, respectively. No symptom was most common subjective symptom in both DF and DFSP. Most of DF presented as brown colored papules and the lesions of DFSP were reported mainly as brown plaques. Histopathologically, the 40 cases of DF were classified as 24 fibrous types, 12 cellular types and 4 aneurysmal types. Of the 11 DFSP, two cases were classified as myxoid type, one case as pigmented lesion (Bednar tumors) and one case as fibrosarcomatous type. Histopathologic findings of the DF showed more significant epidermal hyperplasia, basal hyperpigmentation and collagen trapping, compared to that of the DFSP. The subcutaneous extension and honeycomb pattern were significantly more present in DFSP than in DF. The immunoreactivity of CD34 in DFSP was generally strong and diffuse, in contrast to absent or focal staining seen in DF. CONCLUSION: We conclude that several cilinicopathologic features, including size, location, epidermal and tumoral component, and immunostaining, for CD34 can be used to distinguish DF from DFSP. Further research regarding the characteristics and differences between DF and DFSP should be performed on larger number of cases.

PURPOSE: M. pneumoniae is knwon as a common causative agents of respiratory infection in school children. But, it tends to occur in infants and younger children recently. This study was performed to evaluate the incidence and clinical manifestations of M. pneumoniae pneumonia in infants. METHOD: A total of 142 children(33 infants{Group I : Infants group; 0-2 years} and 109 children{Group II : Children group; 3-6 years}) was admitted with M. pneumoniae pneumonia from January through December 1998. We reviewed medical records and evaluated the incidence, clinical manifestations and laboratory findings. RESULT: Number of patients with M. pneumoniae pneumonia in 0 to 2 years of age(infants group) comprised 23.2% of the total in contrast to 57.1% in 3 to 6 years of age group and 19.7% in 7 to 12 years of age group. Seasonal distribution showed the highest frequency in autumn in infant and children groups(45.5% and 39.4% respectively). The most frequent symptom was cough(90.9% and 96.3%, respectively), followed by sputum(81.8% and 90.8%, respectively), fever(72.7% and 66.0%, respectively) and rhinorrhea(72.7% and 64.0%, respectively). The common physical findings on admission were crackle(84.8% and 80.7%, respectively), wheezing(30.3% and 18.3%, respectively) and throat injection(39.4% and 35.8%, respectively). WBC count was within normal range in both groups(90.9% and 89%, respectively) and CRP was lower than 0.8 mg/dL in 63.6% of infant group and 54.1% of children group. The most common radiologic finding was bronchopneumonia in both groups (47% and 38%, respectively). CONCLUSION: Number of the patients with Mycoplasma pneumoniae pneumonia in infants age from 0 to 2 years comprised 23.2% of the total. Clinical manifestations of Mycoplasma pneumonia in infants were similar to those of older children. We recommened Mycoplasma pneumoniae should be considerd as a causative agent even in infant with respiratory infection.

Sinusoidal hemangioma is a distinctive subset of a group of lesions known collectively as cavernous hemangiomas. Clinically, it develops in adults, predominantly females, and presents as a solitary, painless, bluish, deep dermal or subcutaneous nodule. Lipoma is the most common benign soft tissue tumor. Lipoma is distinguished from sinusoidal hemangioma on both clinical and histological grounds. Several studies have suggested that adipocytes originate from perivascular cells during adipogenesis. Angiogenic cytokines released by adipocytes play a role in the vasoproliferative response. The rearrangement or loss of chromosome 13 can also be associated with hemangioma. However, no previous cases of sinusoidal hemangioma have been associated with benign tumors like lipoma. Here, we describe an unusual case of sinusoidal hemangioma that occurred together with a lipoma on the right upper arm of a 43-year-old male.
