Spindle cell lipoma is a benign tumor composed of ropey collagen, myxoid stroma, CD34-positive spindled cells, and mature fat. The variable proportion of these elements among different cases of the neoplasm makes diagnosis difficult. Furthermore, numerous variants have been reported, including pseudoangiomatous spindle cell lipoma, angiomatous spindle cell lipoma, fibrous spindle cell lipoma, and low-fat or fat-free spindle cell lipoma. Here we report a case of low-fat, fibrous spindle cell lipoma in which fat is noted to be present in <5% of the tumor, whereas fibrous collagenous stroma is predominant.

Tissue temperatures were measured by a thermistor-thermometer, at suprachoroid, inner retinal surface and intravitreous portion (1mm deep), during diathermy applications on the scleral surfaces of rabbit eyes. Castroviejo's Electro-surgical Ophthalmic unit Model S-5 was used and power intensity(current) was fixed to 2, and diathermy was applied on the sclera 3mm, 2mm, and 1mm from and above the measuring points. Measurements were performed in the following groups: Group 1: Spark gap power 2. duration of application 2 sec. Group 2: Spark gap power 2. duration of application 3 sec. Group 3: Spark gap power 3. duration of application 2 sec. Group 4: Spark gap power 3. duration of application 3 sec. Maximum rise of temperature was 20.0 degrees C at suprachoroid, 16.8 degrees C at inner retinal surface and 6.6 degrees C at vitreous in Group 4. Temperature rise in vitreous was much lower than that in suprachoroid and inner retinal surface (table II, which revealed percentage of average rise per tissue temperature before diathermy). Highest measuring temperature at inner retinal surface in this experiment was under 60 degrees C, at which vitreous collagen fibrils may coagulate.

The purpose of this study is to find out what changes occur in the corneal curatures before and after the operation for pterygium and the relationships between the histopathologic findings and the various factors concerned with pterygium. The results are as follows: 1. The degree of corneal invasion of the pterygium head is closely related to the difference between the horizontal and vertical corneal curvatures before operation. 2. The difference between the horizontal and vertical corneal curvatures decre ase after operation. 3. The changes in horizontal curvatures are remarkable in 3 weeks after surgery with a mean change of +0.41 D. 4. In the histopathologic findings, the duration of pterygium and the increased amount of collagen fiber are significantly related(p<0.01). 5. There is no relationship between the histopathologic findings and the changee in corneal curvatures analysed by the SPSS program (p>0.05).

10.Overview of Filler: Compositions, Effects, Rheological Consideration.
Journal of the Korean Society of Aesthetic Plastic Surgery 2011;17(1):1-5
As increasing demands for facial soft tissue augmentation by injection and minimal invasive procedures, filler has become increasingly popular and a suitable method for patients' demands. Over several decades, many filler products have been introduced. Successful clinical application of filler products requires a thorough understanding of their compositions, effects, and rheology. This study reviewed filler products according to the classification of effect duration: permanent, semipermanent, temporary.
