A genetic and clinical study was done on 20 index cases and their families who had lived in Chonnam province, visited Chonnam University Hospital from 1968 through 1983, and were diagnosed as peudoxanthoma elasticum based on clinical and histopathological findings. In Chonnam province, pseudoxanthoma elsticum occurred in a incidence of more thar, one per 125,000. The male to female ratio was 1: 1.25 (8: 10) with only the cases of familial occurrence although the sex ratio was 1: l. 85 (7: 13) among 20 index cases. Among 8 index cases showing familial occurrence, 6 showed autosomal recessive inheritance with 5 Type 1 and 1 Type 2 whereas 2 showed the autosomal dominant inheritance with both of thern Type 2 (Pope), pointing out the genetic heterogeneity in pseudoxanthorna elsticum. The age of patients ranged from 12 to 42 years old at the time of their first visit to our hospital, but the age that the patients first recognized the disease onset ranged from 9 to 22 years old. The duration of t he disease was also variable ranging from 11/2 to 30 years. The angioid streaks were observed in 38g of the cases whose disease duration ranged from 11/2 to 20 years. The sites of skin lesions were the neck, axillae and groin in the order of frequency.

We herein described a female newborn baby who, on the day of birth, exhibited widespread discrete reddish purple colored, round and slightly hyperkeratotic papules measuring about 4 mm in size, the biopsy specimen of which showed the histologic findings of histiocytosis X. The skin lesions resolved spontaneously within a week. The following diseases were discussed as possible diagnoses; histiocytosis X, generalized eruptive histiocytoma, juvenile xanthogranuloma, congenital self-healing reticulohistiocytosis and xanthoma disseminaturn. Since the current case didn't fit well any of them, we proposed a new descriptive term for this : Histiocytoma Papulosa Benigna Congenita.

Zoophiilc dermatophytes are basically animal pathogens, but all can cause dermatophytoses in man. Accordingly animals with dermatophytes are an important source of human dermatophytoses, since zoophilic dermatophytes are frequently transmitted directly or indirectly from domestic or wild animals to man through the use of the se animal as pets, or through contact in rural araes. With the recent increased incidence of zoophilic dermatophytoses worldwide,it is consided to be an important public health problem in view of its epidemiologie aspect i.e. its simultaneous occurence in families or groups. To this time, Microsporum canis in cats has only been sporadically reported throughout the country in the late 1970s and very little is additionally known of the zoopbilic species in animal populations and reservoir or host animals in Korea. Therefore, the authors performed a mycological study by culturing hair and skin lesions of 100 dornestic and 64 zoo animals fortnightly for the purgose of isolating zoophilic derrnatophytes and thereby recognizing the reservoir animals. We also performed an experimental derrnatophyte inoculation in human, mice and rabbits by using Microsporum canis, Trichopyton mentagrophyte vagranulare and Microsporum gypseum isolated from animals and patients lesions from Jan. l980 through Jun. 1981, for the comparison of pathogenicity of these dermatophytes species on human and animals and also for the comparison of pathogenicity of strains isolated from patients lesions and animals and thereby considered different from each other. Microsporum canis was isolated from 11 cats. Trichophyton mentagrophyte var granulare from 3 cats, and Microsporum gypseum from 2 Korean racoon dogs.

It is well known that leprosy bacilli have a special affinity for peripheral nerves, especially Schwann cells but also including perineurial cells and endothelial cells of endoneurial blood vessels. The Schwann cells, after invasion by and saturation with multiplied M. leprae, are destroyed and segmental demyelination and Wallerian degeneration follow. This condition, then is known to be the main neural pathogenosis in early leprosy. It is rarely observed that the progressive paralysis occurs in arrested leprosy patients under adequate treatment. Therefore, the authors performed a histopathologic study of 80 peripheral nerves obtained from the autopsies of 10 old lepromatous leprosy patients including two active cases whose disease durations ranged from 6 to 49 years. The authors arbitrarily divided all the histopathologic findings into 5 grades on the basis of 1) difference in pathological findings in relation to disease duration and bacterial index, and 2) the coexistence of various lesions within the same nerve trunk. As the disease progresses the destroyed nerve fibers are replaced by fibrous and granulation tissue while the perineurial reaction increases. The cellular reaction is minimal in the low grades. There is a slightly early increased vasculature probably due to M. leprae and later a more pronounced increase with large vessels indicating the presence of the granulation process. There is minimum to moderate interfascicular reaction throughout every grade, ie. increased cellularity, vessel wall thickening and increased numbers of vessels with fibrosis. Acid-fast bacilli were demonstrated only in the active cases. The coexistence of different fascicular lesions within the same nerve trunk of peripheral nerve and of femoral nerves mear the spinal cord indicates the presence of some perineurial inhibitory effect which, while promoting the centripetal spread of, prevents the transfascicular spread of M. leprae for some time.

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.

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.

We herein describe two cases of sudoriparous angioma consisting of increased number of eccrine sweat glands associated with angiomatous vascular channels. Case 1 is a 16 year-old girl developing two, painful and tender cavernous hemangiomas which sweated whenever compressed. These were located on her left gluteal area since early childhood. The biopsy specimen revealed an increased number of cystically dilated eccrine glands in the mid-dermis in addition to vascular components in the lower dermis. Case 2 is a five year-old girl manifesting non-tender, slightly hyperhidrotic nevus flammeus-like eruption on her left suprapopliteal area since birth, the biapsy apecimen of which revealed an increased number of eccrine glands admixed with capillary hemangioma in the mid-dermis.
