Fournier Gangrene*

A 58-year-old male presented with a pruritic, erythematous hread-like eruption on the right chest, which appeared as a small papule since 6 months prior to his visit. Histopathologic examination showed a burrow containing numerous eosinophiles and a few mononuclear cells in the epidermis. There was focal spongiosis unde the burrow. In the dermis, there was a diffuse and occasionally dense perivascular and periadnx 1 inflammatory cell infiltration consisting of eosinophiles and some lymphocytes. Multiple histologic sections were made without success in deizo strating parasitic tissue in the epidermis, however, the clinical and histopathologic features we onsistent with cutaneous larva migrans.

We report a case of generalized plane xanthoma which showed no-rmolipoproteinemia and was not associated with unerlying disorders or other type of xanthomas. A 48-year-old female has noticed well defined, slightly elevated, yellowish plaques which occurred on the periorbital areas, sides of the neck, scapular areas, anterior chest, buttocks and lower extremities for 3 years. Biopsy specimen taken from the neck showed perivascular accumulations of foam cells in the upper and mid dermis. Paper electrophoresis didn't, show elevation of any lipoprotein.

We investigated the effect of experimentally induced anisometropia on binocular function. Unilateral myopia, hyperopia, or astigmatism(Axis 90degrees) was induced in eighteen adults with normal binocular function using softcontact lenses. Sensory status was assessed by measuring stereoacuity, Worth four dot test, and Bagolini lens test. Binocular function of all subjects decreased with increasing levels of anisometropia. In Worth four dot test, foveal suppression increased in proportion to the levels of anisometropia. Stereoacuity was similarly degraded by the induced anisometropia. Bagolinilens responses were normal in almost all subjects. Our study suggest that experimentally induced anisometropia cause significant abnormalities in binocular function in adults.

To investigate the correlation of peripapillary atrophy with optic disc dupping and disc hemorrhage in primary open angle glaucoma(POAG) patients, tomographic measurements were performed with Heidelberg Retina Tomograph(HRT, Heidelberg Engineering, Germany). We analyzed cup to disc area ratio(C/D ratio) and peripapillary atrophy to disc area ratio(P/D ratio) from 28 eyes of 14 POAG patients with peripapillary atrophy(Group A), only C/D ratio from 28 eyes of 14 POAG patients without peripapillary atrophy(Group B), and only P/D ratio from 28 eyes of non-glaucomatous subjects with peripapillary atrophy(Group C). Group A was subclassified into thos with disc hemorrhage (Group A-1) and those without dixd hemorrhage(Group A-2), and changes of visual field defects were also analyzed from each subgroup witn Humphrey automated perimetry (Allergan Humphrey, USA, C24-2) at the six-month follow-up. Cup to disc area ratio(0.54+/-0.160)in the Group A was signifcantly higher than that(0.406+/-0.130) in the Group B, and P/D ratio was higher in Group A(0.619+/-0.203) than in the Group C(0.484+/-0.130). P/D ratio was also higher in Group A-1(0.725+/-0.34) than in the Group A-2(0.605+/-0.273). There was no significant difference in mean deviation(M/D) and corrected pattern standard deviation(CPSD) between Group A-1 and Group A-2. The results led us to the conclusion that peripapillary atrophy had significant correlation with glaucomatous damage on optic disc and disc hemorrhage in glaucoma patients. Therefore more attention should be paid tod a glaucoma patient especially when he or she presents with peripapillary atrophy.

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.
