We present a case of generalized grannuloma annulare with perforating and subcutaneous forms which occurred in a 15-year-old girl. Two years ago, multiple umbilicated, match head to pea sized, erythematous papules were noted on the upper extremities. Then the patient also experienced crusted or ulcerated erythematous papular lesions on the lower legs. Recently, tender, subcutaneous nodules appeared on both soles. The biopsy specimens from the skin lesions of the hand and the sole showed typical findings of granuloma annulare in the dermis and the subcutis, respectively. On the histopathological examination of the calf lesion, palisading granuloma as well as transepidermally eliminating dermal collagenous and necrotic material were seen. The skin lesions were almost completely improved by treatment with dapsone, 100mg a day, for 8 weeks orally.

This report presents the case of a 49-year-old man who presented with giant masses that had recently grown on the bilateral sides of the tongue. A clinical examination revealed rubbery yellowish lesions protruding from the tongue.A panoramic radiograph showed an enlarged soft tissue shadow of the tongue. Computed tomography showed well-defined circumscribed mass exhibiting a homogeneous low density on the bilateral sides of the tongue. On magnetic resonance images, the masses showed a high signal intensity on T1-weighted images and iso-signal intensity with partially hyperintense margin on fat-suppressed T2-weighted images. Surgical excision was performed, and a histopathologic examination confirmed the diagnosis of lipoma. The patient recovered well with no sign ofrecurrence. A giant lipoma is defined as a lipoma larger than 5 cm in diameter. A literature review of giant lipomas of the tongue is also presented herein.

BACKGROUND: It is mandatory to measure the minimal phototoxic dose(MPD) in order to determine adequate irradiation of UV-A in photochemotherapy. However, the measurement of MPD is not easy in some cases due to inadequte size and site of lesions, time and manpower. OBJECTIVE: The purspose of this study was to standardize the minimal phototoxic dose for a vitiliginous lesion. METHODS: The minimal phototoxic dose of UV-A was measured in 82 vitiligo patients. Then we analyzed the MPD according to the sex, age, site of the vitiliginous lesions, duration of disease, and administration route of the photosensitizer. RESULTS: 1. There were no significant differences between exposed and unexposed areas in MPD in both cases of topical and systemic administration of the photosensitiser. 2. There was no significant correlation between disease duration and MPD in both cases of topical and systemic administration of the photosensitiser. 3. In the group of topical application of 8-methoxypsoralen cream, MPD for males and females were 0.53+0.38J/cm2 and 0.48+0.32J/cm2 respectively without significant difference in sex. 4. In the group of systemic administration of 8-methoxypsoralen, there was a significant difference between males and females in MPD. The MPD in males and females were 1.38+0.72J/cm2 and 2.51 + 1.40J/cm2, respectively. 5. In the group of topical application of 8-methoxypsoralen cream, the MPD in 2nd decade patients was the highest(0.80+0.55J/cm2). The MPD had a tendency to decrease gradually as age receded from the 2nd decade. 6. In the group of systemic administration of 8-methoxypsoralen, there was a tendency for the MPD to be increased according to age without statistical significance. 7. MPD in the group systemically administrated with 8-methoxypsoaralen was four-fold to that of the topical application group. CONCLUSION: It may be valuable to keep in mind that there was a statistical differrence in MPD between sexes in systemic administration of the photosensitizer, and that MPD was different according to patients age in the topical application group.

To detect causative allergens in type I hypersensitivity diseases, several methods have been used. Among those, skin prick test is easy to perform and sensitive. Several criteria presenting positive reactions have been used. Therefore, we tried to find out more sensitive and specific criteria for deciding a positive reaction on skin prick test in 57 patients(allergic rhinitis; 39, bronchial asthma ; 5, acute urticaria ; 2, chronic urticaria ; 11) with 69 allergens and compared the reproducibility between each positive criteria. We calculated the ratio of wheal size caused by each allergen to that of histamine and defined as "A" in case of it's ratio was over 0.5, "B" in case of over 0.7, "C" in case of over 1.0. The results were as follows, 1. The positive rate of house dust on skin prick test was the highest, and D. farinae, cat fur, D. pteronyssinus, mixture of cat fur, house dust, horse hair, dog hair in order. 2. Mean reproducibilities of four common allergens in each positive criteria were 91% in criteria A, 88% in criteria B, and 82% in criteria C. 3. Comparing between mean reproducibilities by earth positive criteria, in positive criteria between 0.5 and 0.7 and positive criteria between 0.7 and 1.0, there were no significant differences, but in positive criteria between 0.5 and 1.0, statistical significant difference was noted. In conclusion, it was suggested that the ratio of wheal sizes of allergen to histamine greater than 0.7 might be ideal for a positive skin prick test.

A 16-year-old male presented with pain in the right posterior mandible on chewing that had lasted for several months. The radiographic features of the lesion included a radiolucent-radiopaque mixed-density mass with a radiolucent rim attached to the root of the mandibular right first molar. The preliminary radiographic diagnosis was benign cementoblastoma, which was confirmed by histopathological examination following surgical excision. The lesion recurred 3 years after treatment; radiographically, it consisted of 3 round foci with mixed radiopacity, each with a radiolucent rim near the root of the mandibular right second premolar and the edentulous postoperative region. The lesion was diagnosed as recurrent benign cementoblastoma and a second surgery was scheduled. This report presented an unusual case of recurrent benign cementoblastoma following surgical excision and extraction of the involved tooth, along with a literature review on reported cases of recurrent benign cementoblastoma with a focus on its clinical features and the best treatment options.

The majority of patients with an advanced-stage ovarian cancer relapse within approximately 18 months after completion of the first-line therapy. Recurrent ovarian cancer commonly presents as peritoneal seeding, while other distant sites are anywhere including the pleura, liver, lung, central nervous system, spleen, skin, bone, and breast. As pulmonary metastases usually occur through hematogenous or lymphangitic routes, the pattern of the metastases of ovarian cancer is multiple and scattered diffusely. The solitary pulmonary metastasis of ovarian cancer is an extremely rare condition, thus it can be misdiagnosed as a primary lung cancer, unless physician has a clinical suspicion. Herein, we introduce a case of solitary pulmonary metastasis of ovarian cancer which occurred 9 years after the curative surgery and chemotherapy.

BACKGROUND AND OBJECTIVES: The purpose of this study was to investigate whether a brief cardiopulmonary by-pass, with mild hypothermia and normal flow, would have any deleterious effects on brain metabolism in children. This is the first study using localized in vivo proton magnetic resonance spectroscopy (1H-MRS) in brains of children with ASD undergoing open-heart surgery (OHS). SUBJECTS AND METHODS: Seven children undergoing surgical closure of ASD, with mild hypothermia and normal flow cardiopulmonary by-pass, were studied. Their ages ranged from 18 to 47 months, and body weights ranged from 11 to 17 kg. We performed 1H-MRS before OHS, and 1-3 months after, then compared the values of brain metabolite ratios before and after surgery. The values from our patients were compared to those from 12, age-matched, normal children. All MR imaging, and localized 1H-MRS, were performed using a GE 1.5T SIGNA system (General Electric Medical System, Milwaukee, USA). Image guided STEAM-spectra were obtained from, the parietal white matter (PWM), and occipital gray matter (OGM), with TE of 30 msec, and TR of 3 sec, using a PROton Brain Exam (PROBE) (General Electric Medical System, Milwaukee, USA). RESULTS: All metabolite ratios, measured by 1H-MRS, from patients before surgery showed no significantly difference from postoperative values. However, [choline/creatine] ratios, obtained from PWM, were higher in both pre- and postoperative ASD patients, as compared to those of normal children. CONCLUSION: We concluded, that brain metabolism, measured by 1H-MRS, does not change significantly after OHS, for children with ASD, with mild hypothermia and normal flow.

The vibrational spectral differences of normal and lung cancer cells were studied for the development of effective cancer cell screening by means of attenuated total reflection infrared spectroscopy. The phosphate monoester symmetric stretching nus(PO3(2-)) band intensity at ~970 cm-1 and the phosphodiester symmetric stretching nus(PO2-) band intensity at ~1,085 cm-1 in nucleic acids and phospholipids appeared to be significantly strengthened in lung cancer cells with respect to the other vibrational bands compared to normal cells. This finding suggests that more extensive phosphorylation occur in cancer cells. These results demonstrate that lung cancer cells may be prescreened using infrared spectroscopy tools.
