Folliculosebaceous cystic hamartoma (FCH) is a recently recognized adnexal tumor and is composed of follicular, sebaceous and mesenchymal elements such as small vessels, adipocytes and neural component in the fibrous stroma. It usually presents as an exophytic papule or nodule on the central part of the face. We describe a 39-year-old woman with FCH on the right upper back, which is an unusual site. A biopsy specimen demonstrated a follicular structure in infundibuiar nature, sebaceous lobules attached to it, and compactly laminated fibrous stroma with an increased number of vessels in it. Immunohistochemically, many of the vessels in the stroma showed positive reaction for CD34, and Factor VIII.

The double eyelid operation is one of the most common cosmetic surgery performed in orientals, and there are numerous studies about surgical procedures of that. In the case of appropriate candidates, the non-incision technique makes excellent cosmetic results, with the advantages of shorter operating time, less morbidity, less pain, no scarring and easy revision of shape. But, usually the non-incision technique is recommended in the cases with thin upper eyelid, small amount of orbital fat, less redundant skin of upper eyelid and in whom a wide fold is not desired so on. Therefore, the disadvantages of this method are that it cannot be applied to all patients. The postoperative complications are disappearance or faded fold, formation of cyst or lumps, asymmetry etc. and the incidence of these complications is slightly higher than those of the incisional method. In this study, the double eyelid operation using the continuous buried suture method was performed in 210 patients for formation of double eyelid from Jan. 1993 to Dec. 1995. In conclusion very good results can be obtained by the continuous buried suture method even in the cases of puffy upper eyelid. This method can make a double eyelid shape in the fashion the patient wants and can be a new indication for correction of unilateral double eyelid. This method is safe, satisfactory and take shorter postoperative recovery time and it can reduce the incidence of postoperative complications.

PURPOSE: The purpose of this study was to assess the diagnostic accuracy of various quantitation methods using F-18-fluorodeoxyglucose (FDG) in patients with malignant or benign lung lesion. MATERIALS AND METHODS: 22 patients (13 malignant including 5 bronchoalverolar cell cancer; 9 benign lesions including 1 hamartoma and 8 active inflammation) were studied after overnight fasting. We performed dynamic PET imaging for 56 min after injection of 370 MBq (10 mCi) of FDG. Standardized uptake values normalized to patients body weight and plasma glucose concentration (SUVglu) were calculated. The uptake rate constant of FDG and glucose metabolic rate were quantified using Patlak graphical analysis (Kpat and Mrpat), three compartment-five parameter model (K5p, MR5p), and six parameter model taking into account heterogeneity of tumor tissue (K6p, MR6p), Areas under receiver operating charac-teristic curves (ROC) were calculated for each method. RESULTS: There was no significant difference of rate constant or glucose metabolic rate measured by various quantitation methods between malignant and benign lesions. The area under ROC curve were 0.73 for SUVglu, 0.66 for Kpat, 0.77 for Mrpat, 0.71 for KSp, 0.73 for MRSp, 0.70 for K6p, and 0.78 for MR6p, No significant difference of area under the ROC curve between these rnethods v;as observed except the area between Kpat vs. Mrpat (p<0.05). CONCLUSION: Quantitative methods did not improve diagnostic accuracy in comparison with nonkinetic methods. However, the clinical utility of these methods needs to be evaluated further in patients with low pretest likelihood of active inflammation or bronchoalveolar cell carcinoma.

In order to assess the extracellular matrix(ECM) secretion of corneal epithelial cells inoculated with herpes simplex virus-1 in vitro the indirect immunofluorescent technique was used. In this study, ECM such as fibronectin, type IV collagen and laminin were rich in cultured rabbit corneal epithelial cells under the normal condition, while those became poor after inoculation with herpes simplex virus-1. This result suggested that herpes simplex virus-1 inhibit ECM secretion of the corneal epithelial cells. These findings mean that delayed epithelial wound healing after herpes simplex virus-1 infection is due to suppressed secretion of ECM which is the principal component of corneal epithelial wound healing.

BACKGROUND: To analyze the morphologic characteristics of low density lymph node in etiologic differentiation of lymphadenopathy, emphasizing the different features between tuberculosis and lung cancer, on contrast enhanced CT scan,. METHOD: A total of 64 patients who showed low density lymph nodes on chest CT scan were analyzed. Primary causes were tuberculosis (n=28), lung cancer (n=27), malignant lymphoma (n=5) and metastasis from extrathoracic malignancies (n = 4). CT scan was performed with 10mm slice thickness and 7 characteristic features were evaluated: location,size, presence or absence of the nonnecrotic lymph node, calcification, perinodal fat obliteration, thickness and evenness of the enhancing rim. RESULTS: In patients with tuberculous lymphadenopathy, lymph nodes with uneven (68.0%) and thick (62.1%) enhancing rim were more common than lung cancer (p<0.05). Low density lymph nodes with less than 1cm in size were found only in tuberculous lymphadenopathy(n=10). In 48.2% of patients with lung cancer, more than 1 nonnecrotic enlarged lymph node were coexisted, whereas 21.4% in patients with tuberculous lymphadenopathy(p=0.06). However, the size, location and calcification were not statistically significant between tuberculous lymphadenopathy and lung cancer. CONCLUSION: Tuberculous lymphadenopathy is strongly suggested when enhancing rim of enlarged lymph nodes is uneven and thick, when the coexisting nonnecrotic lymph nodes are few in number and when central low density is encountered in normal sized lymph nodes.
