Acne vulgaris was studied from July, 1976, to September, 1976, in 1, 089 high school students by questionaires in Kwangju city. Results were as follows; 1. The prevalence of acne in this group was 71. 2 % There was no difference between boys and girls, 2. Generally, severity of acne in boys was higher than girls. 3. Approximately 80% of all participants who had acne had involvement of the face 4. The mean age of onset was 15. 7 in boys and 15. 2 in girls. 5. Among 53.9% of the participants who reported a seasonal change, there was irnprovernent in acne during fall in boys, winter in gi."1s. 6. Relation between the severity of acne and menstural period was not noticed. 7. Of the students with acne, 58.3% had a familial history. 8.

A study was made on 72 cases of skin tumor and tumorous conditions of the eyelid and periorbita,l areas which were obtained as surgical pathology specimens during the period. of 5 years and 8 months from January, 1977 to August, 1982, at Department of Dermatology, Chosun University Hospital. The results were as follows. Of the 72 cases of skin tumor and tumorous conditions, 65 cases (90. 5%) were benign, and 7 cases (9. 7%) were malignant. The ratio of male vs. female was 1: 3. 6 for benign tumorous conditions and 6: 1 for malignant tumors. The peak age incidence for benign tumorous conditions were at the 3rd decade (R6. 9%). The peak age incidence for malignant tumors were at the R rd decade (28. 6%) and above the 7 the decade (28. 6%). The benign tumorous conditions were 21 cases (82. S%) of syringoma, 21 cases (82. 3%) of pigmented nevus, 6 cases (9. 2%) of epidermal cyst and 5 cases (7. 7%) of xanthelasma. The malignant tumors were R cases (42. 9%) of squamous cell carcinoma, 2 cases (28. 6,.) of basal cell epithelioma and 2 cases (28. 6%) of malignant melanoma. The predilection sites of the benign tumorous conditions were lower eyelid and inferior periorhital area (59. 1%). The predilection sites of the malignant t:umors were lower eyelid and inferior periorbital area (42. 9%).

A case of hypohidrotic ectodermal dysplasia was seen at the Dermatological Clinic of Chosun Univeraity Hospital, with a classical symptom triad consisting of hypohidrosis to anhidroais, hypotrichosis and hypodontia, and characteristic facial appearance. He was a 20 year-old male patient who presented, in addition, milium-like papules of sebaceous hyperplasia located on the nose and cheeks, supernumerary nipples of right breast, ceruminosis since childhood, and absence of apocrine glands on the axilla and pubic area, all of which are not frequently observed in hypohidrotic ectodermal dysplasia. Dermatoglyphics of this patient revealed that the axial triradius of the left palm was t, its atd angle was 42 degree, and the total ridge count of finger print was 5. This patient has no relatives showing the symptoms of hypohidrotic ectodermal dysplasia and the genetics was discussed in relation to this disease.

Daily topical sequential triple therapy(tretinoin, betamethasone valerate and hydroquinone), as proposed by Kligman et al and Gano et al, has been performed on 29 Korean female patients with melasma. After 4 weeks treatment with 2% hydroquinone cream, only three of eight patients (37. 5%) showed good to excellent results. However, after 4 weeks treatment with 4% hydroquinone cream, twelve of twentyone patients (57. 1%) showed good to excellent results and its therapeutic effects appeared more rapidly than the former group. Overall, after 4 weeks treatment. 96.6% of the total group showed fair to excellent results of which 57. 7% had a good to excellent rating. The fair-com- plexioned Koreans had a better response than dark-complexioned.

Primary cutaneous monomorphous lymphoma is rare compared to the more usual involvement of skin secondary to internal monomorphous lymphoma. The histopathological diagnosis of the primary cutaneous monomorphous lymbhoma (PCML) requires differentiation from cutaneous lymphoid hyperplasia. The authors observed 3 cases of PCML. Case 1 was 21 year-old woman, who had an initial lesion on her left arm. Histopathologically it was diagnosed as poorly differentiated. lymphocytic lymphoma and was treated by surgical excision. Six months after onset she developed new lesions on her skin elsewhere, histopathologically diagnosed as well differentiated lymphocytic lymphoma. She died of infiltration of the bone marrow 19 months after the initial onset, even though combination of radiotherapy and chemotherapy resulted in clinical improvernent. Case 2 was a 70 year-old woman having an unusual cutaneous manifestation of an adult palm sized ulcerative, indurated tumor on her right forearm, histopathologically diagnosed as histiocytic lymphoma. There was no evidence of extracutaneous in volvement except right axillary lymphadenopathy. Case 3 was 72 year-old man, who had a clinical manifestation to that of case 2, histopathologically diagnosed as histiocytic lymphoma and received radiotherapy with good improvement. The patient did not show any evidence of extracutaneous involvement five months after the onset.

Colloid miliurn consists of yellowish translucent papules or plecques on the light-exposed skin. Histologically, colloid milium shows sharply circumscribed masses of a fissured, homogeneous, faintly eosinophilic material in the upper third of the dermis. The authors present three elderly female patients of colloid milium who had yellowish translucent papules on the face and dorsum of the hands. The incidence of the disorder may be heigher than has been suspected.

Recently the frequency of Microsporum canis, as a causative dermatophyte of tinea capitis, is increasing in our country. We herein report a case of tinea capitis caused by Microsporum canis in an eight-day-old infant. Infection was contracted, presumably, from a kitten who had tinea corporis caused by the same species of Microsporum and who lived in the patients house. It is extremely rare for tinea capitis to occur in the neonatal period. Although only one case had been reported in the foreign literature, to our knonwledge, a case has never been reported in Korea. We believe that this patient is the youngest patient with Miicrosporum canis infection of the scalp yet reported, and it is also of interest that he has atypical lesions with black-dot-like non-inflammatory alopecic patches on the scalp.

BACKGROUND: Though implant dentistry is very successful and predictable in treatment of patients with destroyed dentition, there are some cases with limitations to implant therapy. In these cases, alternative treatment modality should be considered. CASE DESCRIPTION: A patient with destroyed dentition was rehabilitated with a lateral rotational path removable partial denture. According to the diagnosis, we determined to raise vertical dimension for esthetic and functional restoration. The final restoration was performed after four months of provisional period. CLINICAL IMPLICATION: The edentulous patients with compromised esthetics and functions can be successfully treated with a rotational path removable partial denture through adequate treatment planning and precise laboratory procedure.

Subepidermal calcified nodules, consisting of solitary circumscribed deposits of insoluble calcium within the subepidermis, have generally been assumed to be idiopathic. As the disease is not associated with any systemic or cutaneous diseases, or any biochemical abnormalities, the pathogenesis is still unexplained, and it is thought to be a definite entity with only a characteristic histopathology. We report a 36-year-old female who has had subepidermal calcified nodules on both upper eyelids symmetrically for about 20 years. It is interesting that the lesions have xanthelasma-like appearance and are associated with syringomas. Excisional biopsy showed typical histopathologic and histochemical features of the sub epidermal calcified nodules.
