Fournier Gangrene*

Dermoid cysts develop from sequestration of epithelium along lines of embryonic fusion.The most common locations are the lateral third of the eyebrows, nose, and scalp. These cysts are located in the subcutis; they are often adherent to periosteum, and may invade or erode underlying bane. A 34-year-old female presented with a solitary, skin colored, dome-shaped, child fistsized, subcutaneous mass on her right occiput. At operation, keratinous material was discharged and tufts of hair projected from opening of the cyst wall.The base of the cyst was firmly adherent to periosteum and diffuse depression with focal deep erosions of the outer table of skull was found.

PURPOSE: Metastatic prostatic adenocarcinoma can be controlled by androgen ablation through the active process of programmed cell death in androgen responsive cells. However, about 20-30% of patients have no clinical response to androgen withdrawal. Because of the importance of apoptosis in effecting tumor control, factors involved in this process may be helpful in predicting androgen insensitivity. So, we evaluated the significance of bcl-2 protooncogene expression pattern with therapeutic response of prostatic cancer MATERIALS AND METHODS: We examined the cellular expression of bel-2 protein using immunohistochemical stain in tumor samples from 40 patients with metastatic prostatic cancer(stage D) and determined whether expression of blc-2 protein has related to the therapeutic response of prostatic cancer. RESULTS: The hormonal status of the patient's tumor was determined by the clinical response to therapy. Androgen independent cancer was defined as that subset of patients who experienced no initial response to androgen ablation, or who experienced disease relapse following an initial response to androgen ablation. So, we found that androgen dependent prostatic cancer was 22 patients and androgen independent prostatic cancer was 18 patients. The positive staining for bcl-2 was 27.3%(6/22) and 83.3%(15/18) in androgen dependent and independent prostatic cancer, respectively. It was significant difference(p<0.05). CONCLUSIONS: These results suggest that bcl-2 expression is associated with androgen independent prostatic cancer and used one of the factors to predict which patient with prostatic cancer will respond to androgen ablation.

A 28-year-old man presented with a 6.0 * 5.0 cm sized ulcer on the anterior chest and widespread copper-red colored maculopapular eruptions. There was no past or family history of syphilis sign or STS. He had been taken imposition of hands twice to treat chronic hepatitis about 4 months prior to presentation. Thereby, the ulcerative lesion on the anterior chest developed as a result of erosive trauma through contact with infected fingernails. The clinical features and serologic tests as well as biopsy findings were consistent with syphilis. Spirochetes were observed under the dark field examination of the anterior chest lesion. On Warthin-Starry staining, spirochetes were identified in the epidermal area of the papular lesion. We report a case of unusual transmission of syphilis.

Ovaries lie near the distal ureter where extracorporeal shock wave lithotripsy (ESWL) of calculi is performed. The question whether ESWL may induce morphological changes in ovary should be investigated in animal experiments. After applying shock waves to ovary of Sprague Dawley female rat, the histopathologic changes within the tissue of ovary were observed immediately after shock waves and after recovery. For animal subjects, 25 healthy rats weighing about 250 grams each were used. Five rats were designated as control, and remaining 20 received shock waves at 20 kV for 1,000 times using Pendulum-ESWL (Lithoring), a third generation lithotriptor. The 20 rats were divided into 4 groups before shock waves, and each group was sacrificed after 1, 7, 14, and 28 days, respectively, in order to compare the observed histopathologic changes. Edema, congestion and hemorrhage were observed in ovary after 1 and 7 days of shock waves, but the edema and congestion were significantly reduced on the 14th day and completely disappeared on the 28th day. There was no ovarian follicular changes or fibrosis on the whole. It is thought that the extracorporeal shock waves have no specific effects on the tissues of ovary, but further studies ate needed to determine its long term effects.

BACKGROUND AND OBJECTIVES: Perfluorocarbon exposed sonicated dextrose albumin (PESDA) microbubbles has been suggested to facilitate thrombus disruption under the transcutaneous ultrasound (US). Thus, we investigated whether such a noninvasive approach could augment thrombolytic effect of fibrinolytic agent in an experimental thrombotic model. MATERIALS AND METHODS: Thrombus formation was induced with electrical injury in the rabbit iliofemoral arteries (n=20): Thrombus occlusion was documented by angiography in all arteries. In the control group, only tissue plasminogen activator (t-PA, 3 mg/kg) was administered intrav-enously in five rabbits. In the Group 1 (n=9), injured arteries were exposed to transcutaneous US (20 kHz, 30 W/cm2, continuous mode) with t-PA (3 mg/kg). In the Group 2 (n=6), the same treatment was given while administering PESDA continuously (10 ml/min, intravenous). Angiographic results were evaluated at 10 minute interval for 1 hour respectively. RESULTS: In the control group, two of five iliofemoral arteries (40.0%) were recanalized and one of nine iliofemoral arteries (11.1%) was recanalized in Group 1. In contrast, four of six iliofemoral arteries (66.7%) were recanalized angiographically in Group 2 (p=0.392 vs. control group: p=0.047 vs. Group 1). However, late reocclusion occurred in all iliofemoral arteries of Group 2. CONCLUSION: Although PESDA with transcutaneous US significantly enhanced initial angiographic patency rate of t-PA, it was associated with high rate of reocclusion. Further studies will be necessary for clinical application of this noninvasive method in acute arterial occlusion.

BACKGROUND: Paederus derriattis is a peculiar linear lesion caused by an insect belonging to genus Paederus, family Staptylinidae, order Coleoptera. The deliberate or accidental contact of crushed coelomic fluid of th insect, on the skin causes acute lesions due to a t.oxin(pederin) being released. OBJECTIVE: The study was nade in order to investigate an epidemic status of the peculiar der matitis and its causative agent of factor prevailing in the midwest area of Kyungpuk province. METHODS: We performed field approaches on 633 cases(M: 303, F: 330) including cases enrolled in a local clinic, teamiring up with a local skin clinician over the 3-month period of August November in 1994. RESULTS: 1. The captive insect causing the present dermatits, was identified as Paederus fuscipes(PF). The epidemic might be attributeid to the climatic conditions with higher temperature than usual during the period of July-eary September in the past year by 3-4degrees C as well as a lower relative humidity. The active temperature zone for PF was presumed to be about 15.5+1.2degrees C to 28.9+1.0degrees C 2. There was the highest p;evalence of 412 cases(65.1%) in early September, followed by mid September, late August, early October and mid August in a small number of cases in decreasing order. The cases were not found after mid October. 3. All age groups were evealy represented. The sex ratio was 1: 1.1 with little difference. The majority of cases lived in Kiriich on city(80.3%), with a lesser outbreak in the neighboring coun ties and Kumi city. 4. The preferred site was the mainly exposed area such as face, neck and extremities. The number of lesion was single(60%) and multiple(40%). The lesion showed a common linear con figuration and acute irritant contact dermatitis consistent with the histologic finding. CONCLUSION: The unusual wiather conditions and poor environmental hygiene help to develop an ecosystem breakdown, which, in turn, sometimes influences the innocuous insects life to be harm ful being on humans, as like outbreak of PF dermatitis.

Nevus sebaceus is a common hamartoma that has a variety of appendage tumors. We report a case of nevus sebaceus with multiple appendage tumors on the scalp of a 43-year-old male. The exudative inflamed patches were admixed with darkly pigmented small nodules which had developed secondarily within a 4.0 × 1.5cm lesion 2 years previously. Histologically, on serial sectioning, there were various types of basal cell carcinoma, syringocystadenoma papilliferum, tubular apocrine adenoma and sebaceous adenoma. Some parts of a biopsy specimen, showed a tumor of the follicular infundibulum-like epidermal changes. There were also calcium depositions in the stroma and apocrine tumors, There was no relapse at 1-year follow-up after surgical treatment.
