Histopathologic Findings in Diagnosed lesions as psoriasis / 대한피부과학회지

BACKGROUND: Psoriasis is a dynamic process, both clinically and histopathologically. There is wide spectrum of histological change recognizable in psoriatic lesions. OBJECTIVE: We attempted to clarify the histological features in psoriasis by quantitative studies. METHODS: We reviewed the clinical charts, photographs and skin biopsy slides of 106 patients who were diagnosed as psoriasis clinically or histopathologically between March, 1990 and August, 1994 at the Department of Dermatology, Korea University Hospital. The 12 histopathologic fea tures of psoriasis were listed and examined whether these features were seen or not. in each section. And if seen, then the features were scored 0 to 1. The sum of score in ear,h section could range from 0 to 12. RESULTS: 1. 72 of 106 patients were psoriasis vulgaris. In other patients, the clinical forms of psoriasis wer e guttate psoriasis, pustulosis palmoplantaris, and generalized pustular psoriasis. 2. The average score of histopathologic features seen in each section were 8.11+/-2.11. 3. Sections commonly showed club shaped rete ridges, elongation and ederna of the dermal papil- lae, perivascular mononuclear infiltrate in the upper dermis, absent granular layer, parakeratosis, suprapapillary plate thinning, mitosis above basal cell layer, and dilated tortuous blood vessels. The observed frequency of Munro microabscess, spongiform pustule, and dilated tortuous blood vessels were significantly lower in psoriasis vulgaris than in other clinical forms(p<0.05). CONCLUSION: This study showed that the histologic picture of psoriasis varied with the clinical forms. In each section seen, the observed frequncy of Munro microabscess and spongiform pustule was relatively low.

A Case of Giant Keratoacanthoma

A 63-year-old man had a huge verrucous protruding mass over the suprasternal area. The lesion enlarged rapidly over 3 mooths, and measured about 10×8 cm. The histologic finding of the biopsy specimen showed nests of squamous epithelium with central keratinization, infiltrating the dermis. The neoplasm was treated successfully with surgical excision.

A Case of Romberg Syndrome / 대한피부과학회지

Romberg syndrome is a rare disease and characterized by unilaeril atrophy of the skin, subcutaneous tissue and the underlying structure of half the face. The lesion does not usually cross the midline of the scalp. Roriberg syndrome is sometimes mildsnosed as linear scleroderma, although they differ widely in their clinical and histological apperance. A 13-year-old boy was present with a one year history of idefined atrophic patch on the left side of face and neck. We involved skin was not bound down to the underlying structure. The history revealed no prcvious trauma or disease, He had no abnormal neurologic finding. Computerized tomography demonstrated a diminished subcutaneouat volume and also decreased thickness of back muscle is the left side face from cheek to neck.

A Case of Primary Cutaneous Mucormycosis in a Immunocompetent Patient / 대한피부과학회지

Mucormycosis is an infectious disease caused by fungi of the order Mucorales. Almost all patients have a serious uriderlying condition such as diabetes mallitus, imrnunosuppression, starvation, burn, but a few cais have been reported in previously heilthy subjects. In order to successfully treat this infection, diagnosis must be prompt and acior. panied by aggressive debridement and parenteral administration of amphotericin B. We report a case of primary cutaneous mucormycosis in 58-year-old man. The lesion was a well-circumscribed erythematous plaque with central necrcis Histopathologically, a biopsy revealed broad, nonsptate with branches occuring at right anghles.

A Case of Disseminated Candidiasis with Skin Manifestations / 대한피부과학회지

Candidiasis is the most common fungal infection complicating the course of patients with hematologic malignant neoplasms. Although widespread organ involvement is characteristic of disseminated candidiasis, reports of skin are rare. Reports describing typical clinical and histopathological finding of cutaneous lesions are very important since it may enable a diagnosis of disseminated candidiasis to be made and thus antifungal therapy can be initiated earlier. A 50-year-old housewife was admitted with a 5-month history of fatigue and easy bruising. She was diagnosed as ha.ving acute myelocytic leukemia and treatment was begun with daunorubicin and cytosin, arabinoside. Eight days after the start of chemotherapy, she developed a fever and generalized tender well demacated erythematous to purplish papulonodular eruption. A biopsy specimen from the skin lesion showed perivascular mononuclear cell infiltration and spore and pseudohypae v,rere found within the dermis and subcutis in PAS stain. Cultures of one skin biopsy specimen and one of four blood sarnples grew Candida tropicalis. The patient was treated with intravenous amphotericin B for disseminated candidiasis. On the tenth day of antifun gal therapy, she developed cardiopulmonary arrest and died.

The Clinical Features of Skin Tags and the Association Between Skin Tags and Colonic Polyps / 대한피부과학회지

BACKGROUND: Skin tags are benign fleshy or darker colored papillomatous dermal tumors locatei mostly in the neck, axill or groin. Recent reports on a possible association between skin tags and colonic polyps, however, caused interest in these henign tumors of the dermis, especially wite regarding to their frequercy. OBJECTIVE: The purpose rate this study was to explore the clinical profiles of skin tags, the effect of obesity on the frequeny of skin tags and the association between skin tags and obesity in the normal population. We also tried to evaluate the usefulness of skin tags as a general marker for the presence of colonic piyps. METHODS: The first, 524 unselected patients were examined. The patient material comprised of 240 males and 284 females. Each patient was inspected with regard to skin tags by a clermatolgist. 334 patients were classified into obese groups and nonobese groups and then we evaluated the relationship between skin tags and the degree of obesity. The second, ninety consecutive patients referred for coloniscopic evaluation were examined to determine the association between skin tags and colonic polps. RESULTS: We found 22.9% of the males and 22.5% of the females to be skin tag carriers in the general population. We also noticed a steady increase of the frequency according to age eccept for the third decads. Of the skin tags found 51% were in the axillar region, 40% around the neck and 8% in the inguinal region. In the study for the relationship between skin tags and obesity, 44.9% of the obise patients and 23% of the nonobese patients were skin tag carriers(relative risk=1.95, p<0.05). In the study for the association between skin tags and colonic polyps in patients undergoing colonoscopic examination, 18 of patients with skin tags(45%) hnd colonic polyps and 11 of patients without skin tags(22%) had colonic polyps(relative risk=2.05, p<0.05). CONCLUSION: This study identified an obese group that are at risk of the developing skin tags. Consideration of skin tags as a marker for colonic polyps is likely to prove helpful.
