Focal nodular hyperplasia is a benign hepatic tumor mainly composed of nodules of hepatocytes and Kupffer cells separated by fibrous septa. In general, it is difficult to differentiate focal nodular hyperplasia and hepatocellular carcinoma on ultrasonography, conventional CT(computerized tomography), and angiography. But IV bolus CT is of particular value in the diagnosis of focal nodular hyperplasia because it can divide enhanced CT into early and late phase and can characterize tumor vascularity and analyze any intratumoral elements. In our case, it was seen as a hypoechoic mass lesion on ultrasonograpl'hy and hyperdense mass lesion on early-phase IV bolus CF and isodense mass, lesion on late-phase IV bolus CT. On angiography, hypertrophy of the feeding artery and tumor staining were well visualized. The patient underwent operation and the mass was pathologically confirmed to a focal nodular hyperplasia. We report the first case of focal nodular hyperplasia on IV bolus CT in Korea.

Mycetoma is a clinical syndrome of localized, indolent, deforming, swollen lesions and sinuses, involving cutaneous and subcutaneous tissues, fascia, and bone. Its lesions. are composed of suppurat.ing abscesses, granulomata, and dra ning sinuses and the etiologic agents are wide variety of bacteria (actinomycotic mycetoma) and fungi(eumcotic mycetoma) from plant and soil. The patient was a 65-year-old female and a farnier. She was referred by the skin lesion loalized on the dorsum of her lefther left hand and wrist for three months. It showed multiple subcutaneclis nodules, abscesses, and discharging fitula based on the erythematous plaque. The skin biopsy frorn the lesion revealed the PAS positive hyphae in the granulocytic infiltration. Fungus cult,ure with a piece of tissue on sabouraud media shows hin, floccose, white colonies. Slide culture and biochemical idcrtification of pathogen led to the final diagnosis as Mycetoma caused by Pseudallescheria boydii(Monosporium apiospermum). The lesions disappeared gradualy following systemic oral administratior of Itraconazole 200mg daily for six weeks.

An etiologic agent in seborrheic dermatitis is now considered to be due to Pityrosporum ovale. The connection between the yeast and the disease has been clearly dernonstrated in a number of patients treatd with antifungal agents. However, the fact, that Pityrosporum ovale (Pityrosporum orbiculare) belongs to the normal human cutaneou. flora makes it difficult, to explain the role of the organism in seborrheic dermatitis. In this clinical study, twenty eight subjects were divided into two group by treatment regimen of topical 2% ketoconazole shampoo(TKS)and 0.3% prednisolone valerate solution (PVS). Before and during the four weeks treatment periods, the number of Pityrosporum ovale on the scalp were evaluated by scrub Giemsa staining method, which estimat,ed by score scale, under direct. microscopic examination. Also clinical symptoms including erythema, scales and itching were recorded by scores every week and compared between two treatment group. Topical application of 2% ketoconazole shampoo(TKS) is a very effective treatment regimen to reduce the yeasr cell score(from 5.8+1.3 to 1.8+1.4) than PVS(from 6.4+1.3 to 3.5+1.5), significantly(p<0.05). So the results of this study acconsistent with the view that density of Pityrosgourum ovale plays a role in the cause and course of seborcheic derrnatitis on the scalp. And antifungal agent(TKS) shows favorable effects ori tnis disease clinically and mycologically.

Erythroplasia of Queyrat is an uncommon form of carcinoma in situ involving the glans penis and adjacent mucosal structures. Treatment modalities of Erythroplasia of Queyrat vary widely and topical 5-fluorouracil treatment is very effective and regarded as the choice of t eatment. This article reports a case of erythroplasia of Queyrat involving the perimeatal region of the glans penis and identifies the difficulty of effectively treating erythroplasia of Queyrat which is adjaer to the urethral meatus with 5-fluorouracil and usefulness of electron beam irradiation therapy.

Congenital absence of nails usually occur as a rare isolated anomaly or combined with other ectodermal defects. This anomaly is regarded as an inherited disorder either dominantly or recessively but quite a few cases were reported as sporadically developed. The patient was a 2-month-old girl who had no nails on both her 2nd, 3rd toes but had rudimentary nails on her left big toe and both 4th toes at birth. We could not find any other congenital deformity, any family history of inherited diseases related to anonychia. Radiological findings revealed no visualization of both 4th distal phalanges, only. We report this case as congenital anonychia of a sporadic type which may have developed independently from an underlying bone abnormality. We also review other reported cases in the literature.

Leprosy is a multisystemic infectious disease showing various cutaneous manifestations by the reaction between Mycobacterium leprae (M. leprae) and host immunity. We de-scribe a 20-year-old woman with clinical multiple papulonecrotic skin eruptions resembling papulonecrotic tuberculid (PNT) and pityriasis lichenoides et varioliformis acuta (PLEVA). This kind of skin eruption is a new manifestation which has not been reported so far in lepromatous leprosy (LL).

9.Development of 99mTc-Transferrin as an Imaging Agent of Infectious Foci.
Nuclear Medicine and Molecular Imaging 2006;40(3):177-185
PURPOSE: Purpose of this study is to synthesize 99mTc-labeled transferrin for infection imaging and to compare it with 67Ga-citrate for the detection of infectious foci. MATERIALS AND METHODS: Succinimidyl 6-hydrazino-nicotinate hydrochloride-chitosan-transferrin (Transferrin) was synthesized and radiolabeled with 99mTc. Labeling efficiencies of 99mTc-Transferrin were determined at 10 min, 30 min, 1 hr, 2 hr, 4 hr and 8 hr. Biodistribution and imaging studies with 99mTc-Transferrin and 67Ga-citrate were performed in a rat abscess model induced with approximately 2 x 10(8) colony forming unit of Staphylococcus aureus ATCC 25923. RESULTS: Successful synthesis of Transferrin was confirmed by mass spectrometry. Labeling efficiency of 99mTc-Transferrin was 96.2+/-0.7%, 96.4+/-0.5%, 96.6+/-1.0%, 96.9+/-0.5%, 97.0+/-0.7% and 95.5+/-0.7% at 10 min, 30 min, 1 hr, 2 hr, 4 hr and 8 hr, respectively. The injected dose per tissue gram of 99mTc-Transferrin was 0.18+/-0.01 and 0.18+/-0.01 in the lesion and 0.05+/-0.01 and 0.04+/-0.01 in the normal muscle, and lesion-to-normal muscle uptake ratio was 3.7+/-0.6 and 4.7+/-0.4 at 30 min and 3 hr, respectively. On image, lesion-to-background ratio of 99mTc-Transferrin was 2.18+/-0.03, 2.56+/-0.11, 3.08+/-0.18, 3.77+/-0.17, 4.70+/-0.45 and 5.59+/-0.40 at 10 min, 30 min, 1 hr, 2 hr, 4 hr and 10 hr and those of 67Ga-citrate was 3.06+/-0.84, 4.12+/-0.54 and 4.55+/-0.74 at 2 hr, 24 hr and 48 hr, respectively. CONCLUSION: Transferrin is successfully labeled with 99mTc, and its labeling efficiency was higher than 95% and stable for 8 hours. 99mTc-Transferrin scintigraphy showed higher image quality in shorter time compared to 67Ga-citrate image. 99mTc-transferrin is supposed to be useful in the detection of the infectious foci.

In one case of advanced systemic scleroderma hyperbaric oxygen therapy was performed. The treatrnent were given in an one-man pressure chamber (made in Korea) at a pressure of 2. 5 atmospheres absolute pressure (AT.A). The pressure was increased in 5-7 minutes, kept constant for 1.5 hours and lowered in 5--7 minutes. After 16 weeks of the treatment, regression of the skin contraction was achieved, together with improved mobility of the joints and healing of ulceration.
