Sixty-six cases of erythena nodosum(EN) and erythema induraturn(EI) were examined pathologically and clinically. Pathologically 23 cases were erythema nodosum, 43 cases were erytherna induratum. Pathological diagnosis made without any prior knowledge of the clinical and laboratory data. Clinical manifestations were reviewed on basis of pathological diagnosis. The results are as follows; l. EN and EI mainly occurred in female, age of twenties and during spring season. There was no difference in sex, age and seasonal incidence between EN and EI. 2. Both EN and EI affected chiefly the shins. EI was more common than EN in cases of calf involvement. 3. Tenderness and systemic symptoms developed more often in EN, while ulcers occurred only in EI. 4 EI had relatively long duration. There was no difference in the recurrence rate between EN and EI. 5. Pulmonary tuberculosis was found only in El on chest X-rays. 6. Clinical and pathological diagnosis was identical in almost cases of EN but those were variable in case of EI.

BACKGROUND: The histopathological findings of acute cutaneous graft-versus-host reaction are similar to that of erythema multiforme. OBJECTIVE: The objective of this study was to compare the histopathological findings of acute cutaneous graft-versus-host reactions with that of erythema multiforme. METHODS: Histopathological setions of 9 patients with grade 2 acute cutaneous graft-versus- host. reactions and of 13 patient,, with erythema multiforme were reviewed. RESULTS: Parakeratosis, the degree of the exocytosis and the endothelial cell swelling were not useful in the differential diagnosis between acute cutaneous graft-versus-host reactions and ery- thema multiforme. Rete ridge effacement and relative hyperkeratosis were characteristic in many cases of acute cutaneous graft-versus-host reactions but absent in erythema multiforme. Spongiosis, vacuolar degeneration of the basal cells, perivascular lymphocytic infiltration and erythrocyte extravasation were usually more prominent in erythema multiforme than in acute cutaneous graft-versus-host reactions. The number of dyskeratotic cells per epidermal linear mm was usually higher in erythema multiforme but not in acute cutaneous graft-versus-host reactions. An eosinophilic infiltrate was observed occasionally in erythema multiforme but not in acute cutaneous graft-versus-host reactions. CONCLUSION: The histopathological findings show the same pattern of interface dermatitis and are different only in degree beween acute cutaneous graft-versus-host reactions and eryt,hema multiforrne. Rete ridge effacement and relative hyperkeratosis speaks for a diagnosis of acute cutaneous graft-versus-host reactions, and an eosinophilic infiltrate for a diagnosis of erythema multiforme.

A clinical and histopsthological study were done on 1,817 biopsied inflammatory skin diseases among 58,386 out-patients in Dermatologic department of Korea University Hospital during the period of 24 years from January, 1962 to December, 1985. The results were summarized as follows : 1. According to pattern analysis(Ackerman AB), 1,605 cases(88.3%) of inflammatory skin diseases were classified into 9 patterns and by author's modified pattern analysis, additional 437 cases could be classified. 2. Of the 1605 cases which were classified by 9 pattern analysis, 1185 cases(78.8%) of inflammatory skin diseases were diagnosed as individual disease entity. The ratio of accordance between the histopathological diagnosis and clinical diagnosis on the biopsied inflammatory skin diseases was 44.5%, 3. The ratio of accordance between the histopathological diagnosis and clinical diagnosis by the patterns were '. Vasculitis(75.5%), Subepidermal vesicular dermatitis (73.3%), Nodular and diffuse dermatitis(68.2%), etc. 4. The diseases showing above the 70% accordance were scleroderma, erythema induratum, vitiligo, arthropod reaction, etc; and the diseases showing under the 30% accnrdance were erythema multiforme, erythema annulare centrifugum, neurodermatitis, etc.

Erythema nodosum is clinical entity defined easily, but because of the variable histopathologic findings showing involvement of the vessels, septa, and fat lobules, the histopathologic features often are not compatible with the clinical diagnosis, We present the results of clinical and histopathologic findings in 26 patients with erythema nodosum observed at the Department of Dermatology, Seoul National University Hospital, fram January 1973 to August 1976. 1. Clinical Findings Erythema nodosum is characterized by painful erythematous nodose lesion occurring symmetrically(92%) on shins(50%) or shins and calves(50%) of women(M: F==4: 22) between sixteen to twenty five years old of age(58%) chiefly. In laboratory study, leukocytosis(1/17) was rare but increased titers of antistreptolysin(64%) and elevation of E.S.R.(88%) were found frequently. 2. Histopathologic Findings Even though hemorrhage(73%), perivascular(100%) and periadnexal(85%) inflammatory cell infiltration were frequently seen in histopathologic changes of erythema nodosum, these changes were nonspecific. Moreover, granulomatous change (38%), thrombophlehitis(35%) and necrosis of fatty tiasue(38%) were observed not infrequently in erythema nodosum. So we concluded that there were no specific histopathologic findings in erythema nodosum which differentiated from the other erythematous nodose diseases on the legs consisted of panniculitis, thrombophlebitis or granulomatous changes.

Autoimmune progesterone dermatitis is a rare disorder involving hypersensitivity to progesterone. It is most frequently characterized by recurrent erythema multiforme, eczematous or urticarial eruptions during the luteal phase of the menstrual cycle. It resolves or partially improves after menstruation. Sensitivity is demonstrated by a challenge test with medroxyprogesterone acetate. The therapeutic goal for autoimmune progesterone dermatitis is the suppression of ovulation. Currently, the first-line choice of therapy is a combination oral contraceptive. Here, we report a case of autoimmune progesterone dermatitis that manifested as cyclic bullous erythema multiforme. A reactive intradermal progesterone test confirmed the diagnosis.

The authors present seven cases of Democidiosis in rosacea type and the subject of human demodetic infestation has been reviewed. According to our experience, demodex folliculorum, although a normal inhabitant of the sebaceous glands in small numbers, when encouraged to multiply by the patients excessive use of facial cream and avoidance of soap, can produce democidiosis. The diagnosis was easily confirmed by characteristic clinical appearance and simple microscopy. The characteristie clinical appearances are indurated non-comedous papules and pustules with unique cherry pinkish red erythema. The response to treatment, consisting of daily soap and water cleansing of the face, followed by the local application of a suitable antiparasitic remedies is simple and gratifying. But the erythema was not respond to antiparasitic preparation.

PURPOSE: Recently, a number of rapid antigen detection tests have been available to diagnose group A streptococcal pharyngotonsillitis. The purpose of this study was to determine the sensitivity, specificity and consistency of the two rapid antigen detection tests. METHODS: Among the patients who visited our clinic from November 2001 to February 2002, 61 patients who had clinical findings of pharyngeal erythema or edema, pharyngeal exudates and soft palatine petechiae were enrolled in our study. A total of 61 patients were tested with rapid antigen detection tests and throat culture. BD LINK2TM Strep A(Becton, Dickinson and Company, U.S.A.) and QuickVue(R) In-LineTM(Quidel Corporation, U.S.A.) were selected for rapid antigen detection tests. RESULTS: Of the 61 patients tested, 22 patients were confirmed as group A streptococcal pharyngotonsillitis by throat culture. The BD LINK2TM Strep A had a sensitivity of 81.8% and a specificity 89.7%. The positive and negative predictive values were 81.8% and 89.7%, respectively. The QuickVue(R) In-LineTM had a sensitivity of 77.3% and a specificity of 100%. The positive and negative predictive values were 100% and 88.6%, respectively. The kappa values of BD LINK2TM Strep A and QuickVue(R) In-LineTM were 0.72 and 0.81, respectively. CONCLUSION: In addition to high sensitivity, specificity and consistency, both kits are easy to use and simple to interpret, and therefore have the potential to be used with backup throat culture for diagnosis of acute pharyngotonsillitis.

Polymorphous light eruption(PMLE) is an idiopathic, scquired syndrome characterized by a delayed abnormal response to light and a varied morphology of recurrent erythema, papules, vesicles or plaques on light-exposed areas of skin. We report herein s 42-year-old male patient who was clinically and histologically compatible with PMLE. To confirm the diagnosis, the phototest was performed by 50,J/crn of UVA, 5MED-UVB and visible light irradiation to the extensor surface of the forearm. Numerous erythematous papules developed at the (JVA-irradiated site. The histopathologic findings of the phototest induced lesion were compatible with PMLE. Therefore, our patient was confirmed as having PMLE with action spectrum in the IJVA range.
