A Case of Verrucous Hemangioma / 대한피부과학회지

We report herein a gigantic case of verrucous hemangioma occuring in a 15 year-old school- boy. The lesion was a dark red colored, 10.0 x 6.0 x 0.8cm sized, verrucous surfaced, hemangiomatous tumor affecting the posterior aspect of the right thigh. At birth an erythematous macule appeared and insidious]y increased or extended with age. In the last 6 months, it had grown rapidly to the size of the present lesion with a smaller satellite one, assumably ascribing to the repeated minor trauma or pressure. Histological findings from the totally excised lesion showed epidermal hyperplasia with irregular acanthosis and papillomatosis and diffuse marked proliferation and dilatation of blood vessels from the upper dermis to subcutaneous fatty tissue. Wide excision was done. There was no relapse after about one years postoperative follow up.

A Case of Atypical Polypoid Dermatofibroma / 대한피부과학회지

Atypical polypoid dermatofibroma(APDF) represents a distinctive clinicopathologic variant of dermatofibroma. We describe an unusual case of APDF occuring on the right buttoack in a 27-year-old female. The lesion was a reddish-hued, rounded, hard protuberant tumor with short pedicle, measuring 2,7 x 2.7 x 1.5cm. Excised tumor showed a well circumscribed dermal lesion localized in the protruded ar~ea, and dense proliferation of fibroblasts and capillaries reminiseent of fibrous or scle~rosing hemangioma type, with prominent focal cellular atypia. The tumor cells were vimentin-positive, but did not express CD34. There was no evidence of recurrence after 18 months postoperative follow-up.

Giant Cell Tumor of Tendon Sheath: A case Report

We report a case of giant cell tumor of the tendon sheath in a 36-year-old male, who presented an asymptomatic, firm, 1.0 × 0.8 × 0.4cm-sized nodule, involving the volar aspect of the distal phalanx of the right index finger about 1 year ago. Histopathologically, the enucleated lesion showed four lobules surrounded by thin connective tissue, each of which demonstrated the variable cellularity and the polymorphic cell population consisting of foam cells, spindle-shaped fibroblasts, histiocyte-like cells and multinucleated giant cells with heavy hemosiderin deposits near the periphery, in the collagenous stroma. He has done well with no recurrence during one year of follow-up since the operation.

Malignant Lymphoma of Mucosa-associated Lymphoid Tissue Arising in the Conjunctiva

We report two cases of malignant lymphoma of mucosa-associated lymphoid tissue arising in the conjunctiva. Case 1, an 18-year-old girl, showed her left lower conjunctival swelling for four months and Case 2, a 29-year-old man, showed similar lesions on both his eyes for one year. Histologically, both cases revealed monomorphous dense lymphoid infiltrates invading the overlying conjunctival epithelium with diffuse patterns. The infiltrates were composed of small lymphocytes admixed with centrocyte-like cells within the conjunctival epithelium and stroma in association with B-cell lineage. No relapse was noted during the period of about 1½ years follow-up in case 1 treated by local excision only and in the follow-up period of 2 months in case 2 treated by local excision and subsequent chemotherapy.

Epidemiologic Study of Paederus Dermatitis Prevailing in the Midwest Area of Kyungpuk Province / 대한피부과학회지

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.

A Case of Metastatic Tuberculous Abscess of Skin Following Intestinal Tuberculosis / 대한피부과학회지

We reported herein a rare case of a 65-year-old female who lead intestinal tuberculosis of about 2 months duration, with little late development of metastatit berculosis abscess of the skin. The lesions were egg tow wolnut-sized abscesses or nodules occu in, on the back, right flank and lower abdomen with no pain or mild tenderness. Physical exami saion was unremarkable on dissemination of other sites. The tuberculin test was negative. The skin esions were diagnosed by clinical, histopathologic features, and positive results for Mycobactc iuntuberculosis in smear.; and cultures in the pus discharge: as well as polymerase chain reaction nethod on the nodular lesion. A barium enema showed the findings of intestinal tuberculosis, with positive culture in the stool. A combined treatment was intituted. During the initial 4 month, utaneous lesions did not respond and in some cases worsened with the multidrug of isoniazicr fampin, pyrazinamide and streptomycin, all of which were surgically excised. Thereafter, the drugs of isoniazid and rifampin were further administered for ahout 14 months, with the complete resecution of both lesions and the systemic symptomatolo. There was no relapse at follow-up after 6 months.
