We report herein a case of desmoplastic trichoepithelioma in a 73-year-old female, who is the oldest among the patients of the disease reported in Korea. She had an asymptomatic, hard, annular lesion, measuring 0.6 x 0.7 cm with an elevated border and a depressed center on the left nasolsbial fold. Histopathological findings showed narrow strands of basaloid tumor cells, horn cysts and a desmoplastic stroma.

To determine the value of ultrasonography for the diagnosis of testicular rapture due to blunt trauma, we reviewed 69 patients of blunt scrotal trauma, which were evaluated by ultrasound before treatment. Thirty patients were managed conservatively, of which 3 cases were explored lately due to persistent pain or mass, and 39 explored immediately. Of the 30 patients treated conservatively the injury was resolved in 27. Surgical exploration of the 42 cases revealed testicular rupture in 29 and simple hematocele in 13. Analysis of the 29 cases with testicular rupture demonstrated that orchiectomy rates were 20% in early exploration and 53% in delayed exploration. in the 27 cases the testicular rupture was correctly diagnosed by ultrasonography, and there were 4 false-positive and 2 false-negative diagnoses of rupture. The specificity and sensitivity for the diagnosis of testicular rupture are 70% and 93%, and the positive and negative predictive values are 87% and 82%, respectively. Ultrasonography used in conjunction with a thorough physical examination is highly sensitive in identifying testicular rupture, and can provide objective information supporting the need for early surgical exploration in patients with blunt scrotal trauma.

Color developers(CD) have been noted to produce lichen planus like eruption as well as eczematous contact dermatitis. The chemicals involved are derivatives of paraphenylenediamine or aniline, i. e., Kodak CD 2, Kodak CD 3, Agfa TSS. We report a 28-year-old male who showed a feature of lichenoid contact dermatitis after exposure to color developer. Patch test revealed positive reactions to CD2, CD3 and CD4. Skin biopsy from a patch site showed lichen planus-like tissue reaction.

We are reporting a case of molluscum contagiosum in a 3-year-old boy who showed a good response to diphenylcyclopropenone (DPCP) immunotherapy. The lesions were multiple, 2 to 7mm in size, centrally umbilicated, normal skin-colored papules of 7 months' duration which were distributed on the penoscrotal area, extremities and trunk. In spite of several treatments using extraction and curettage, new lesions developed continuously. The patient was sensitized with 0.1ml of 1% DPCP solution in acetone on his right shoulder and there-after challenged with solution of varying concentrations (0.05 to 0.1%) on his left shoulder once or twice a week to maintain a mild eczema. Clinical improvement was noted 1 week after sensitization and almost all of the lesions cleared after 8 week's treatment.

BACKGROUND: Various kinds of pathogenic and non-pathogenic fungi have been isolated from the house dust, the closest environment of human beings. OBJECTIVE: Our purpose is to investigate the distribution of yeasts in house dust. METHODS: House dust was sampled from 22 families in Taegu and 56 in a rural town in Kyungpook province for 2 months from May to June, 1992. It was cultivated for years on the media containing cycloheximide (500mg/L) RESULTS: Among 78 families, 56 (71.8%) showed positive culture for yeasts in house dut;1 species in 24 (30.8%), 2 species in 19 (24.3%), 3 species in 12 (15.4%) and 4 species in 1(1.3%). Rhodotorula(Rh). Ruora was the most frequently isolated one from 36(46.2%) out of 78 families, followed by Tricosporn(T.) cutaneum 25(32.1%). Candida (C.) albicans 16 (20.5%), Pityrosporum pachydermatis 4 (5.1%) and Torulopsis candida, Cryptococcus laurentii, C. rugosa and C. guillermondii 1 (1.3%), each. CONCLUSION: Rh. rubra, T. cutaneum and C. albicans were the most important yeast species in the houst dust of both rural and raban areas.

Recently, several reports of extrahepatic hepatocellular carcinoma metastasis demonstrated by technetium-99mTc-IDAs scan have shown that 99mTc-IDAs can be used to detect extrahepatic metastasis in hepatocellular carcinoma. We report here a case of hepatocellular carcinoma with pulmonary nodules that were demonstrated as metastasis in nature by the use of the 99mTc-DISIDA. The findings in this case and several reports reviewed here suggest that the 99mTc-DISIDA scan may be a useful diagnostic agent that can detect the extrahepatic metastasis of hepatocellular carcinoma and stage the disease. But more clinical study in needed to establish the position of 99mTc-DISIDA in the field of diagnosis of extrahepatic hepatocellular carcinoma.
