Leydig cell tumor of the ovary is a very rare tumor which usually occurs in the postmenopausal age, and which is frequently associated with virilization. It has been classified as a lipid cell tumor due to the presence of intracytoplasmic lipids. However, since up to 25% of these tumors contain little or no lipid, the new term "steroid cell tumor" is proposed for this type of neoplasm. We report a case of Leydig cell tumor of the ovary in a 16 year old girl. The patient exhibited recently recognized hirsuitism and secondary amenorrhea. Physical examination revealed moderate obesity with moderate amounts of coarse hair over the whole body and a deepening of the voice. Testosterone and dehydroepiandrosterone sulfate levels were markedly elevated in the peripheral blood. Pelvic ultrasonography revealed a right ovarian tumor. The resected ovary showed a well demarcated, golden yellow to orange colored solid mass, measuring 7 cm on the cut surface. Microscopically, the tumor was composed of solid and diffuse sheets of tumor cells having abundant eosinophilic cytoplasm, and large round nuclei with frequent crystalloids of Reinke in the cytoplasm. To our knowledge this is the first case of Leydig cell tumor of the ovary in a young girl in the Korean literature.

We studied 30 patients who participated in accelerated rehabilitation program after ACL reconstruction to evaluate the effects on knee joint function prospectively. This program emphasizes early full hyperextension, early weight bearing as tolerated, and closed-chain quadriceps functional activities with rapid return to sports. Timing of the return to occupation, activity level, manual knee test, range of motion, thigh circumference, Lysholm knee score and KT-2000 arthrometer measurement were checked at the latest follow-up which is at least more than 1 year. The result were as follows: 1. The mean time for patients to return to occupation was 7.5 weeks (2 weeks-6 months). 2. Range of motion of the knee were not limited in 25 cases (83%) at 1 year after reconstruction. 3. The mean Lysholm score was 92.7. 4. The mean manual maximum KT-2000 arthrometer score was 2.0mm. The results of this study show that patients who had an ACL reconstruction with an autogenous central 1/3 patellar tendon graft and followed an accelerated rehabilitation program obtained longterm stability, achieved full range of motion, had a low complication rate, and were able to return to full sporting activities predictably.

OBJECTIVE: To evaluate the tumor response and patient survival rate following transcatheter arterial chemoembolization (TACE) in recurrent hepatocellular carcinoma (r-HCC) after living donor liver transplantation (LDLT). MATERIALS AND METHODS: Twenty-eight patients with r-HCC underwent one or more cycles of TACE after LDLT (mean, 2.5 cycles). After a mixture of iodized oil and anti-cancer drugs was injected via the arteries feeding the tumors, these vessels were embolized with a gelatin sponge. Tumor response was determined by follow-up CT imaging on all patients four weeks after each TACE procedure. Patient survival was calculated using the Kaplan-Meier survival curve. RESULTS: After TACE, targeted tumor reduced in size by 25% or more in 19 of the 28 study patients (67.9%). However, intrahepatic recurrence or extrahepatic metastasis occurred in 21 of the 28 patients (75.0%) during the 3-month follow-up period and in 26 of the 28 patients (92.9%) during the 6-month period following TACE. Extrahepatic metastasis was noted in 18 of the 28 patients (64.3%). The 1-, 3- and 5-year survival rates following TACE were 47.9, 6.0 and 0%, respectively, with a mean survival of nine months in all patients. There were no significant complications related to TACE. CONCLUSION: TACE produces an effective tumor response for targeted r-HCC after LDLT. However, the survival rate of patients with r-HCC after LDLT is poor due to extrahepatic metastasis and intrahepatic recurrence.

Prurigo pigmentosa is a chronic pruritic inflammatory dermaoss characterized by erythematous papules in a reticulated pattern that resolve leaving a reticulated, mottled hyperpigmentation. Most cases have been reported from Japan. Two cases of prurigo pigmentosa have been reported in Korean women. We experienced a casc of prurigo pigmentosa in a Korean man of 20 years of age. Histopathological findings of reddish papule showed exocytosis, sponsiosis, intraepidermal vesicles, hydropic degeneration of basal cells in the epidermis, and hyphohistiocytic infiltration in the upper dermis. Direct irnmunofluorescence was negetive. Therapy with dapsone, 50 mg given daily, resulted in a rerinable regression of the reddish papules. The daily dose of clapsone was reduced to 25mg; however, no new reddish, pruritic papules have appeared.

BACKGROUND: The aim of this study was to compare the efficacy of ketorolac, paracetamol, and paracetamol plus morphine on pain relief after thyroidectomy. METHODS: Eighty patients were randomly allocated to one of the 4 groups: normal saline (group C), ketorolac 30 mg (group K), paracetamol 1 g (group P), and paracetamol 700 mg plus morphine 3 mg (group PM). Each regimen was administered intravenously (IV) 30 min. before the end of surgery. If pain was not relieved, patients received an IV bolus of pethidine hydrochloride 25 mg. Pain intensity using a visual analogue scale (VAS) was recorded at 0.5, 1, 2, 4, and 6 hr after the end of surgery. RESULTS: VAS at 0.5 and 1 hr after the end of surgery were significantly lower in group K, group P, and group PM than in group C (P < 0.05). The number of patients receiving pethidine hydrochloride at 0.5 and 1 hr after the end of surgery was significantly lower in group K, group P, and group PM than in group C (P < 0.05). There was no significant difference among the groups in the incidences of adverse events associated with study medications and patient satisfaction (P > 0.05). CONCLUSIONS: Paracetamol 1 g IV possesses a similar analgesic efficacy to ketorolac 30 mg IV after thyroidectomy. Paracetamol may represent an alternative to ketorolac for pain prevention after mildly to moderately painful surgery in situations where the use of NSAIDs is unsuitable.

We present 2 cases of invasive extramammary Paget disease occuring in the vulva area of a 60 year old female, and in the scrotal and penile area of a 63 year old male patient. The histologically typical Paget cells were not only seen in the surface epithelium but were also involved in the outer root sheath of the hair follicles. Stromal infiltration of tumor cells into the upper dermis were present in both cases, however, no underlying primary sweat gland carcinoma was present. Metastatic foci of inguinal lymph nodes showed apocrine-type epithelium with abundant eosinophilic granular cytoplasm, which were positive for anti-CEA and GCDFP-15, as well as eccrine-type epithelium containing mucinous secretory materials in the lumen and the cytoplasm. Ultrastructural findings showed interdigitating plasma membranes with prominent desmosomes between the Paget cells, intracytoplasmic tonofibrils, intracellular tubules, lipid vacuoles, and enlarged mitochondria. Histological, immunohistochemical, and ultrastructural findings suggested that Paget cells showed both eccrine and apocrine differentiation.

The authors analyse the ultrasonographic findings of 10 cases of appendiceal mucocele retrospectively. In atotal of 10 cases, 6 cases showed only cystic masses with posterior reinforcement. The remaining 4 cases showedinternal echoes in the cystic masses. Differential diagnosis of mucocele from periappendiceal abscess is notpossible in ultrasound. The possibility of mucocele shold be considered if cystic mass in right lower quadrantabdomen is observed in ultrasound.

NAG activity has been measured in the urine of hypertension, diabetes mellitus and renal disease subjects. Results have shown significantly higher levels of Urinary NAG in hypertension, diaetes and renal disease subjects compared to normal control Subjects group(P<0.001). Urinary NAG measurement is simple and accurate and it provides a valuable information in the early detection of renal dysfunction in hypertension and diabetes subjects and also in the follow up of these patients.
