In the past, parasitic diseases were a major problem in public health in Korea. In recent years, however, nematodiasis that used be prevalent are no longer a serious problem. Instead some cestodiasis, particularly cysticercosis and sparganosis have become comparatively more important in recent years. Parasitic infestation of soft tissue is presented as a subcutaneous nodule or mass with nonspecific clinical manifestations. We experienced 4 cases of parasitic infestation in the soft tissue diagnosed by fine needle aspiration (FNA). Three out of four cases were histologically confirmed, two out of four cases were cysticercosis and one case was confirmed as sparganosis. FNA may be useful in providing a diagnosis in cases of parasitic infestation.

Meningioma originates from arachnoid cap cells and is the second most common intracranial tumor; however, it can also be found in an extracranial location. A very rare primary extracranial meningioma without the presence of an intracranial component has also been reported. Primary extracranial meningiomas have been found in the skin, scalp, middle ear, and nasal cavity. A computerized tomography or magnetic resonance imaging scan is necessary to determine the presence or absence of an intracranial meningioma, and a biopsy is essential for diagnosis. We report a case of primary extracranial meningioma located in the forehead skin of a 51-year-old male.

Recent advances in radiological and serological techniques have enabled easier preoperative diagnosis of sparganosis. However, due to scarcity of cases, sparganosis has been often regarded as a disease of other etiologic origin unless the parasite is confirmed in the lesion. We experienced a case of sparganosis mimicking a varicose vein in terms of clinical manifestations and radiological findings. Sparganosis should be included among the list of differential diagnosis with the varicose vein.

Eccrine spiradenoma is a rare adnexal tumor of the skin and its cytomorphology has seldom been described in literature. To evaluate the cytologic features and diagnostic pitfalls of eccrine spiradenoma, we report a case of 33-year-old male whose clinical presentation was a painful subcutaneous mass at the right preauricular area. Fine needle aspirates revealed tight clusters of multilayered, uniform, cuboidal cells arranged around hyalinized perivascular spaces. Some epithelial cells showed tubules or rosette formations. The background showed scattered, naked nuclei. The histologic findings confirmed the eccrine spiradenoma. The recognition of peculiar cytologic features and clinical correlation could be helpful in the diagnosis of skin adnexal tumors.

Pilomatricoma is a well defind and characteristic entity histologically, but this tumor may be encountered during aspiration biopsy of subcutaneous mass, and is, occasionally, confused with other neoplasms, particularly squamous cell carcinoma, basal cell carcinoma, and epidermal inclusion cyst. Recently, we have experienced a case of pilomatricoma diagnosed by aspiration biosy. The smear of the aspirate revealed anucleated "ghost" squamous cells, basaloid or basophilic squamous cells and nucleated squamous cells, which lack nuclear features of malignacy. These findings are consistent with pilomatricoma.

Kimura's disease is a chronic inflammatory condition producing subcutaneous tumor-like nodules mainly head and neck regions. Elevated serum Ig E levels and peripheral blood eosinophilia are common. Kimura's disease represents and aberrant immune reaction to an as yet unknown stimulus. This case presented is 27 year old female whose chief complaint were painful swelling on Rt cheek and temporal area and diagnosed as Kimura's disease. We preformed surgical excision of the mass on Rt. cheek and temporal area and reconstructed with temporal flap and about 100 cc of free fat graft on the defect of Rt. cheek.

A methadone-diazepam interaction study in rats was performed in which conjugated metabolites of methadone were analyzed using deuterated biosynthetic internal standards. Diazepam (5mg/kg) was given to rats through a cannulate djugular vein and a subcutaneous dose of methadone (10mg/kg) was given. Bile was collecte through the cannulate dbile duct over a period of 24 hours. The deuterium label of the internal standards was found to be stable under conditions of the prolonged incubation. There was no significant difference in the excretion of the metabolites between the control and the diazepam treated rats. Feasibility of using biosynthetic internal standards with selected ion monitoring was established for the drug metabolism and kinetic studies.

The auricle is a three-dimensional cartilaginous frame covered with thin overlying skin. Due to its complex features, reconstructing helical rim defects after the excision of an auricular mass is challenging. Shortage of subcutaneous tissue and the presence of a tightly bound epithelium further hamper the primary closure of lateral (anterior) auricular skin defects. We present herein a case in which we used a helical rim advancement flap along with an additional postauricular skin flap. We achieved a satisfactory esthetic result with minimal loss of helical diameter and a low risk of flap necrosis by preserving the vascular network of the flap. This technique is less traumatic and will facilitate faster healing as well as improved patient recovery.

Postmenopausal women are at increased risk for osteoporosis and obesity due to changes in hormones. The relationship between osteoporosis and body weight is known, and its relation with body fat mass is discussed. The purpose of this study was to evaluate the bone mineral density(BMD) changes of epicardial adipose tissue(EAT) and abdominal subcutaneous fat. The subjects of this study were 160 postmenopausal women who underwent BMD and echocardiography. The thickness of the epicardial adipose tissue was measured in three sections and the BMD were meassured according to the diagnostic criteria. The results of this study that age increase the risk of osteoporosis increases, and as the weight and BMI decrease, the risk of osteoporosis increases(p<0.05). The relationship between changes in bone mineral density and adipose tissue in postmenopausal women, increased epicardial adipose tissue was negatively correlated with the bone mineral density(p<0.05). conversely, increased abdominal subcutaneous fat thickness was positively correlated with bone mineral density(p<0.05). In other words, the effect of bone mineral density on the location of adipose tissue was different. If Echocardiography is used to periodically examine changes in the thickness of the epicardial adipose tissue, it may be prevented before proceeding to osteoporosis.
