We describe herein a case of tick bite ocurring to a 23-year-old man who has a characteristic lesion clinically and histopathologically. The tick(Ixodes sp.) was still attached to the brownish and erythematous, indurated skin of the scrotum. The engorged tick which was carefully removed from the skin with a scalpel was 8.7mm in length and 5. 5 mm in width. Histopathologically, characteristic amorphous eosinophilic materigl is deposited around a round space where the hypostorne of the tick was inserted. Heavy inflammatory cell infiltratton in the mid and lower dermis is composed mainly of neutrophils and eosinophils. A certain area of the lower dermis shows edema and capillary dilatation along with the mixed inflammatory cell infiltration, TVide excision of the indurated lesion including the tick was done. The clinical and hsitopathological findings of the tick bite was discussed.

Cleft lip and/or palate(CLP) is the most common congenital deformity in the craniofacial region. For a practical public health system for these patients it is necessary to have an understanding on the prevalence of CLP. However, it was difficult to estimate the exact number of CLP patients due to problems in sample selection, higher miscarriage and still birth rate, difficulty in classification, and adoptions to foreign countries. Therefore this study was to estimate the prevalence of CLP and the rate of orthodontic treatment, which is usually necessary in cleft lip and/or palate patients. The samples consisted of 218,322 Korean male adults from Seoul, Kwangju, Taegu and Pusan, all born in 1979. The screening method for recognizing the CLP patients was proceeded in steps and the results are as follows. 1. The prevalence of cleft lip and/or palate in Korean male adults born in 1979 was 0.65 out of the 1000 samples. 2. In the anteroposterior aspect of the 1000 samples, the prevalence of cleft lip, cleft lip and palate, and cleft palate was 0.26, 0.36 and 0.03 respectively. 3. In the transverse aspect of the 1000 samples, the prevalence of left, right and bilateral cleft was 0.35, 0.16, 0.12 respectively. The cleft in the left showed a much higher prevalence than in the right, while bilateral cleft showed a lower prevalence than unilateral cleft. 4. The orthodontic treatment rate of Korean male adults among cleft lip and/or palate patients was 35%, and it was in the order of cleft lip and palate, cleft lip, and cleft palate, being 67%, 29% and 29% respectively. The orthodontic treatment rate in patients with the more severe cleft lip and palate was higher than in patients solely having cleft lip or cleft palate.

Pigmented fungiform papillae of the tongue is a rare disorder in Korea. It is characterized clinically by pigmentation confined to the fungiform papillae and histopathologically by the presence of melanophages in the upper dermis. We report a case of pigmented fungiform papillae of the tongue in a 21-year-old woman who had brown to violaceous dots on the fungiform papillae and pigmented patches on the right lateral dorsum of the tongue. Histological findings showed increased melanophages in the upper dermis.

Acrokeratoelastoidosis of Costa is a rare palmoplantar keratoderma with autosomal dominant inheritance. It is clinically charaeterized by small, firm, yellowish, shiny, translucent papules occumng over the dorsal hands, the knuckles, and the lateral margine of the palms and soles. Histologically, the characteristic features are hyperkeratosis, aeanthosis, and most strikingly, fragmentation of coarse elastic fibers within the dermis. The lesions usually begin in early childhood and progress slowly. We herein report two familial cases of acrokeratoelastoidosis of Costa showing typical clinic1 and histopathological features.

The present study was carried out to clarify the anatomical changes of lumbar intervertebral discs by aging. Anterior height, posterior height, anteroposterior diameter of intervertebral discs were measured on 512 normal plain lateral radiographs of lumbosacral spine. And the indices of disc wedging and relative disc height were calculated. There was a cephalocaudal gradient of increase in the indices of disc wedging in all age groups. The indices of relative disc height were constant at all lumbar levels. These suggest that the lower disc is more wedge shaped and the height of discs changes in the constant ratio with that of vertebral body.

We report a case of congenital vellus hamartoma, which consists of numerous matured vellus hair follicles and sebaceous glands. This patient is 4-month-old male with multiple, variable sized nodules on the right epicanthsl fold area since birth. Histopathologically, some of the infundibular portion of the vellus hair shows irregular and reticulated hyperplasia. There are numerous well-formed vellus hair follicles surrounded with thick fibrous sheath and some of them are associated with rudiment sebaceous glands.

We report a case of sebaceous hyperplasia showing linear arrangement in a 13-year-old girl. The lesion was found at birth and became prominent gradually. Multiple small discrete yellowish papules were arranged in a linear pattern on the temporal srea of the face. Unusual, incidental histopathologic finding was a sebaceous lobule lying in a dilated infundibular portion, which appeared to represent transfollicular extrusion of sebaceous lobule as a natural phenomenon.

We present herein two cases of acquired periungual fibrokeratoma occuring beneath the proximal nail folds. A firm duplicated and mitten-shaped protruding mass was found on the left middle finger nail of 38-year-old woman and a firm triplicated and finger-shaped protruding mass was found of the left great toe nail of 46-year-old man. The epidermis of the tumors showed compact hyperkeratosis, focal hypergranulosis, and irregular acanthosis. Thick collagen bundles and dilated capillaries were predominantly oriented in the direction of the longitudinal axis of the lesions. There were no adnexal elements and inflammatory cells in the dermis.
