Positron emission tomography (PET) with 2-[F-18]-Fluoro-2-deoxy-D-glucose (FDG) was performed in ninteen patients who had benign musculoskeletal tumors in order to determine if there was a relationship between histologic grade of tumor and FDG uptake of tumor. These patients had been evaluated previously with computed tomography (CT) or magnetic resonance (MR) imaging or both. The diagnoses were confirmed with incisional or excisional biopsy or by radiographic follow-up. Generally high-grade tumors had significantly greater uptake of FDG than low-grade lesions . Benign lesions such as giant cell tumor, fibrous dysplasia, and osteofibrous dysplasia showed significant elevation of SUV (Standardized Uptake Value) above 4.0. On the contrary. The current studies suggest the utility of FDG-PET imaging as an adjunct to CT or MR imaging in the evaluation of benign tumors. And results of PET suggest benign tumors with high SUV are histologically active lesion and tend to be locally aggressive.

BACKGROUND: Alopecia areata is replete with data from studies using variuos therapeutic approaches, none of which is clearly superior to another. OBJECTIVE: This study was designed to evaluate the therapeutic effect of cryotherapy in alopecia areata. METHODS: Thirty three patents with AA(M:13, F:20) well conduted in this study, precluding 3 patients with the moderate and extensive lesions. Cryotherapy using a cotton swab dipped with liquid nitrogen was applied to the involved areas, repeated with 2 times of freeze thaw cycle of two seconds. In 13 cases of AA multiplex, the lesions were divided into two groups, each of which was undertaken cryotherapy and intralesional injection of triamcinolone(3mg/ml) for evaluation of their respeetive effects. The treatment was done weekly method of 1 to 11 times, Th therapeutic response was determined as the regrowth of terminal hairs on the treated area(s) at 12 Weeks. RESULTS: Of the 33 patients with AA, the overall responders were 22(66.7%). There seemed good response rates of 70.0 % in females, 71.4 % in AA multiplex and 72.2 % in third decade as well as 72.4 % in those with lower than 1 year of duration. The remarkable resionse had 3-4 times in treatment numbers. There were no untoward side effects in patients except mild erythema. In the 13 patients treated with both modalities, cryotherapy had a slightly higher esaonse than triamcinolone therapy (69.2% vs 61.5%, p>0.05 by x-test). CONCLUSION: The effect of cryotherapy therapy in AA patients is not less than the intralesional therapy of triamcinolone. In addition, cryotherapy may be recommendec as the new, safe therapeutic modality.

We report a rare case of sporadic keratosis punctata palmaris et plantaris in a 49-year-old woman. Thirty years ago, firm semitranslucent papules developed on the middle portion of her palms without any subjective symptom. The lesions had flat-topped smooth surfaces. They were concentrated along the margins of the hands, especially on the lateral surfaces of both index fingers and finger tips/ Ten years ago, similar hyperkeratotic papules with or without central craters developed on the weight bearing portions of her soles. Her family and past histories were negative. The biopsy specimen revealed a dense hyperderatotic stratum corneum which fitted into a cup shaped depression in the stratum malpighii and a turning inward of the rete ridges at the margin. The Masson trichrome and elastic strains showed no peicific dermal changes.

Quality control survey was done on the plasma triglyceride determination of six laboratories and following results were obtained. 1) Coefficients of variation were less than 5% in 3 laboratories and over 10% in one laboratory. 2) High interlaboratory variation was inferred from the mean values ranging from 104.0~136. 4mg% (sample A) with enzyme method and 44.7~65.3 (Sample B) with acetylaceton method. 3) Establishment of normal plasma triglyceride level in Koreans and supervised quality control by the authority seemed to be urgent.
