We report herein a case of multiple glomus tumors on the scrotum in a 14-year-old boy. The lesions were present at birth and had gradually increased in size and number. Pea to thumb tip sized, dark colored nodules without pain sensation were confined to the scrotum. Histopathologically, there were many dilated and irregular vascular spaces lined by a single layer of flattened endothelial cells in the dermis. In the periphery of the endothelial cells, there are a few layers of glomus cells. No capsule was seen. Total excision of the tumors was performed. No recurrence was observed for an year after surgical excision.

We reviewed two cases of keratosis punctata palmaris et plantaris(KPP) and the scanning electron microscopic findings(SEM). The skin lesions of KPP are multiple, hyperkeratotic on the palms and soles with central pitting. There was no subjective symptoms. The histologic findigs revea,l marked hyperkeratosis, hypergranulosis, and acanthosis with depression of the underlying malpighian layers. The SEM findings reveal one hyperkeratoic plug on punctate lesion(case I ) and three hyperkeratotic plugs on depression of the malpighian layer(case ll ).

For the purpose of epidemiologic study, the patients who visited Severance Hospital Behcet's Syndrome Specialty Clinic were grouped by Shimizu classification into the complete, incomplete, suspected types and evaluated. The results of the evaluation with respect to personal characteristics, geographic distribution, socioeconomic characteristics, family history, and clinical characteristics are as follows. 1. The incidence among the subgroups was incomplete type(46.3%), suspected type(36.7%), complete type(17.0%) and the male to female ratio was 0.60: 1, and the average age of onset was 29.1. years for males and 27.6 years for females. 2. The occupational distribution among males included office workers, 31.5%; drivers, 10.6% and among females was office workers, 6.7%; teachers, 3. 7 %; unemployed, 81.7%. 3. Among the presumed aggrevating factors affecting oral cavity, recurrent tonsillitis(20.8%) was most common, and premenstrual exacervation(12.8%) was most common. 4. The most common initial major manifestation was oral ulcer(80.6%), and the longest duration of major manifestations was oral ulcer(average 6.4 years), and the most frequent relapse of major manifestations was oral ulcer(average 14.6 times/year). 5. The average duration between the appearance of the first and second major manifestations was 5.2 years for complete type, 6.3 years for incomplete type, and 6.6 years for suspected type. 6. Combinations of major manifestations most commonly included oral ulcer, genital ulcers and skin lesions(65.3%) for incomplete type, and oral ulcer, skin lesion(54.8%) for suspected type.

Intravascular papillary endothelial hyperplasia is a benign solitary turnor that may be histologically misdiagnosed as angiosarcoma. We present herein a case of intravascular papillary endothelial hyperplasia occuring in 40-year-old female who hsd a slowly growing tumor on the tongue for 3 years. the histopathologic findings revealed. papillary endothelial hyperplasia in blood vessel accompanied with thrombi.

The eruptive collagenoma is a connective tissue nevus without family history. We report a case of eruptive collagenoma in a 5 year old boy, who had multiple, variable sized orange colored nodules on his back since birth. The histopathologic finding showed increased number and size of collagen fiber and increased dermal thickness.

One hundred sixteen C57 BL mice were painted with either 8-MOP, 5-MOP or TMP solution in concentrations of 0.02%, 0.1%, and 0.5% each and UVA irradiated. Skin biopsies were performed at 1, 3, 5 and 7 weeks after LJVA irradiation. The results measuring the number, area, and perimeter of the melanocytes after topical PLJVA were higher in the TMP-painted group than in the 8-MOP or 5-MOP painted groups. In all groups, the weekly changes showed an increasing value through five weeks. In comparing the drug concentrations used, 0.1% of chemicals produced the same or higher values than 0.5%. There have been few studies on the effects of 5-MOP in photochemotherapy. In tho study 5-MOP produced a pigment-producing effect similar to 8-MOP. Therefore, if topical PIJVA with 5-MOP is used in clinical practice, we could expect a significant therapeutic effect in vitiligo.

This study was undertaken to investigate the recovery of epidermal Langerhans cells in relation to time after UVA irradiation through different amounts and ways of exposure in CH mice. We irradiated the ears of C2H mice with UVA 200J/cm2 and 400J/cm2 in a single dose at one time or 5 fractionated doses for 5 days and performed biopsies on the ears of the control and experimental groups after 2, 7, 14, 21days of irradiation and stained them with immunoperoxidase method. The results are summarized as follows, l. We observed a significant decrease in the number of the Ia-positive epidermal Langerhans cells in the single-dose-exposed group compared to the fractionated- dose-exposed group on 7th and 14th days irradiated with UVA 200J/cm. 2. There was no significant difference in the change in the number of the Ia- positive epidermal Langerhans cells until 21 days of exposure between the single- dose-exposed group and the fractionated-dose-exposed group irradiated with UVA 400 J/cm 3. In the group irradiated with UVA 2003/cm, the reduced number of the Ia-positive epidermal Langerhans cells returned to normal on the 14th day after irradiation in the fractionated-dose-exposed group and on the 21st day in the single- dose-exposed group. In the group irradiated with 400J/cm, the number returned to normal on the 21st day of irradition both in the fractionated-dose-exposed group and in the single-dose-exposed group.

Asphyxiating thoracic dysplasia(ATD;Jeunes's syndrome) is a rare variety of short limb dwarfism. It is characterized by an extremely small thorax when compared to the ab-dominal circumference, which frequently results in respiratory distress. Other anomalies as-sociated with Jeune's syndrome are pelvic bone malformations and renal dysplasia. It was first described and namely by Jeune et al. in 1954. Jeune's syndrome is an autosomal rece-ssive trait and has a 25% recurrence risk. These patients died at early age due to respirat-ory insufficiency. Death due to uremia has occurred in number of children surviving infan-cy, following progressive renal failure, hypertension and hepatic failure. About 50 cases have been reported in the world literature. We experienced a case of small thorax with short limb dwarfism on antenatal ultraso- und examination and then the baby was delivered by cesarean section. The diagnosis was confirmed to Asphyxiating thoracic dysplasia by clinical features, radiological findings and pathological findings. We reported a case of Asphyxiating thoracic dysplasia with review of literatures.
