This clinical study of nine patients presented Disseminated Superficial Actinic Porokeratosis (DSAP) as a distinctive and recognizable entity characterized by multiple uniformly small, irregular marginated, keratotic plug with atrophic center developing during second or third decade of life on sun exposed area of skin. Six of nine patients had DSAP, which was inherited as autosomal dominant trait. The patient's father, two brothers and two sisters were known to have same skin lesions. Of nine patients, five were female and four were male. Eight patients were developed DSAP lesions during second decade of life and other one was third dcade of life. Three patients had pruritus. In alI patients, lesions were developed bilaterally over sun exposed area but was not always symmetrical. The number of lesion was multiple in all patients. The greatest number of lesions were found on distal part of extremities, neck, face, upper portion of anterior chest and back.

Korean Journal of Dermatology 1974;12(2):43-47
The case of a 30 year old man is described, in whom mycosis Fungoides was originating from nose and followed by tumor stage of Mycosis Fungoides on skin. In January 1970, the patient leveloped nasal tumor, when he was n at E.N.T. department of Severance Hospital. At that time a biopsy of nasal tumor demonstrated only a non-specific inflammatory cell infiltrated mass. He received radiation therapy (Co 60) with satisfadory suppression of mass and resulted in right nasal septal deviation. Jn December 1970, thumb sized painful non-tender, movable mass developed on right supraclaviular area. In August 1971, thumb sized painful, tender, movable mass appeared at right posterolateral aspect of neck, which was excied and removed at local clinic. But excised wound was not healed and the mass was enlarged. One month after above lesion, pea sized same mass developed. On physical examination, there were 4*5cm round, erythematous, painful, tender, granulomatous ulceration mass on right postero-lateral aspect of neck and also same mass on postero-inferior site of above lesion. Two times of biopsy was done and it interpreted as tumor stage of Mycosis Fungoids. Treatment included radiation therapy with Co 60 (200r/day, total 6,000r), prednisolone 40mg/day and antibiotics. There has been good response 1 month after radiation therapy and mass is diminished in size and would begin to heal.

Dermatologic treatment was greatly advanced when topical corticasteroids were introduced for the management of many inflammatory and pruritic dermatoses. Their use reduced or diminished mnst of the undiserable side effects which accompanied the systemic administration of these compounds. The good effects of topical application of hydrocortisone had been demonstration in the treatment of variaus dermatoses eg., atopic dermatitis, seborrheic dermatitis, contact dermatitis etc. The halogenated derivatives followed and led to the trend to most of analogs now in use. Especially, fluocinolone acetonide cream greatly enhanced its therapeutic effectiveness in psoriasis, chronic discoid lupus erythematosus, pustular bacterid, granuloma and neurodermatitis circumscripta. But many side effects of topical corticosteroids such as steroid acne. Stria were developed and also fluorinated topical corticosteroids resulted in telangiectasia, purpura, atrophy in skin. Weber reported that strong topical corticosteroids eg.. Betamethasone valerate and fluocinolone acetonide were resulted in rosacealikc dermatitis and it was steadily increased. These adverse side effcts of topical corticosteroids, especially steroid acne, were indisputable argument in dermatologic field, for the view that this topical corticosterodis is used for cosmetics and treatment of acne vulgaris in our country. Since the strong corticosteroid tnpical preparation, the peculiar form acne, so called steroid acne, was steadily increased in our clinic. Behrman and goodman reported that acneform eruption induced by hormone was not associated with oiliness and there were but few comedone. Sullivan and Zeligman reported that the the acneform eruption due to adrenal corticaa 1 hormone was uniform in size, small papule and few pustule, usualIy erythematous base. There were also differential histologic feature. The most important difference is the normal apperance of sebaceous glands in acneform eruption due to corticosteroids contrast with hyperplasia in acne vulgaris. Abscess formation was more frequent and more extensive in acne vulgaris. Sutton Jr and Van Scott & MacCardle described that histologically, the major component in lesion of steroid acne was excessive keratinization of follicle. Castor and Baker demonstrated that topical application of corticosteroids resulted in decrease of sebaceous gIands, decrease of mitosis and increased cornification in epidermis. The present study investigated clinical case of the steroid acne, which are induced by topical application and systemic administration of corticosteroids and experimentally induced the steroid acne with the topical application of corticosteroid. And also clinical cases and experimentally induced steroid acne were compared with acne vulgaris. Material and method Subjects are 13 Patients of steroid acne induced by strong topical corticosteroid eg., fluocinolone acetonide, fluocortolone, dexamethaone, betamethasone valerate and 4 patients of steroid acne induced by systemic administration of corticosteroid eg., prednisolone and also 10 patients of acne vulgaris. Biopsy was performed from 13 patients of topical steroid acne, 3 patients of steroid acne induced by systemic administration of steroid and one patient of acne vulgaris. In order to induce steroid acne, experimentally, strong topical corticosteroid such as beta methasone valerate, fluocinolone acetonide and fluocortolone were applied on back. Comment and conclusion In Clinical feature, the steroid acne by topical application and systemic administration of corticosteroid and experimentally induced steroid acne had unique clinicall features, that showed absence of comedone and uniform sized follicular papule on deep seated erythematous scaly base. The topical steroid acne was distributed the region where were applied. But the eruption of the steroid acne induced by systemic administration of corticosteroids was distributed to face, neck, and scalp. Above findings are quite different form acne vulgaris. Histopathologically, the steroid acne induced by topical application and systemic administration of corticosterojds showed hypoplasia of sebaceous glands and excessive follicular keratinization. Occlusion of pilosebaceous opening by keratotic plug in severe case by long term application showed atrophy of epidermis and sparsity of sebaceous glands with hypokeratosis and parakeratosis. In experimentally induced steroid acne, it was definitely specific features which were absolutely identcall with above cinical steroid acne.

Erythroplasia of Queyrat is a precancerous lesion, usually located to glans penis or prepuce. It is characterized by a slowly developing, circumscribed, usually velvety and shiny patch. The etiology was unknown, but it is extremely rare in those circumcised in early infancy. It had been suggested that phimosis had some etiologic importance. The typical case of Erythroplasia of Queyrat is presented. A 46 year old man had 4 months history of dark-brownish pea sized maculopapular rashes on sulcus of glans penis and prepuce associated with mild itching, which was increased in number day by day. He had a phimosis. On examination, there are sharply defined, slightly elevated, pea sized dark-brownish maculopapular rashes over erythematous infiltrated base on sulcus of glans penis and prepuce, which have moist and velvety appearance. A biopsy was performed from sulcus of glans penis. Histopathologically, there was acanthosis, with in epidermis many cells are vacuolated and showed individual cell keratiinization. Epithelial cell showed marked atypia, variation in nuclear size and there was intercellular, intracellular edema. The lesion was treaterd with topical application of 5% 5-fluorouracil twice daily 2 weeks and thereafter for 4 weeks. 2 months after treatment, no erythroplastic lesion was found and 3 months after treatment, rebiopsy was perforrned which showed marked improvement histopathologically.

Many investigators were interested in the pathogenesis and the relationship between microscopical features and clinical behavior of hydatidiform mole. Trophoblastic cells in the trophoblastic disease were intensively examined histologically, ultrastructurally, immunohistochemically, and with hormone assay method, etc. But ultrastructural study on the stroma of hydatidiform mole was scarcely reported. In this paper, hydatidiform mole was examined at light and electron microscopic levels, with emphasis on the stroma. The results were as follows: 1) Hydropic degeneration of H-mole is more severe in the center of stroma and is not related with the degree of trophoblastic proliferation. Hofbauer cell and vascular structure are extremely rarely observed in the periphery of stroma which has relatively preserved cellular components. 2) Basement membrane is sometimes separated from trophoblastic layer. Degenerated cells in the stroma contain vacuoles, autophagosomes, and lipid droplets. Collagen is abundant in the loose interstitium. Hofbauer cells have no lysosome or phagosome. Vascular lumen is patient and endothelial cells are degenerated. From the above results, H-mole may be produced due to abnormal changes of trophoblasts and stromal changes may be a secondary process, so called autolysis. Hofbauer cells are not engaged in the stromal degeneration and may be different from usual tissue macrophages.

Only a few cases of cyst related to cruciate ligament were reported in the literatrure. It is not only because of rarity but also difficulty of diagnosis by conventional method. Recentely, the precise intraarticular structure of the knee joint became to be seen by introduction of MRI and arthroscope and cycts would bave been found incidentally during the workup of the internal derangement of knee. We have experienced three cases of ganglion around the cruciate ligament in the patients whose symptom was mimic of intemal derangement of knee. We excised the ganglion with good clinical results.

Pulmonary vascular hypertension is characterized by migration and proliferation of smooth muscle cells accompanying abnormal synthesis and accumulation of extracellular proteins in vascular wall. The aim of this study is to define the role of endogneous TGF-betas and PDGF in the process of remodeling vessels through determining the temporal and spatial distribution of these growth factors in hypertensive pulmonary vessels in monocrotaline-induced pulmonary hypertension in rat. Sprague-Dawley rats were sacrificed 12 hours, 1, 2, 4, 7, 10, 14, 21, 28, and 56 days after treatment. The morphometric analysis of medial thickening and immunohistochemical study using antibodies to TGF-beta1, TGF-beta2, TGF-beta3, and PDGF were performed. Immunoreactivities for TGF-beta1 and TGF-beta3 were increased from the 14th day in the medial smooth muscle cells and PDGF showed increased expression from the 21st day in the medial smooth muscle cells. No difference in TGF-beta2 immunoreactivity was found between control and experimental groups. The expression of TGF-beta1, TGF-beta3 and PDGF increased in medial layers with the progressive thickening of pulmonary arteries which was considered to have close relation to medial hypertrophy of pulmonary arterioles. In the case of PDGF, however, the morphologic change occurred before increase in immunoreactivity was observed in the medial layer of pulmonary arterioles. Moreover, the function of isoforms of TGF-beta has yet to be completely elucidated; the different affinity to receptors and the degree of expression of these receptors that are supposed to affect the function of growth factors. Thus, further studies are needed.

It awakens interest that the frequency of carcinoma of the uterine cervix is the highest among the carcinomas among the Korean women, althouth it is not so high among Westerns. It is admitted that the exfolicative cytologic technique is useful not only as a screening test for early detection of cervical cancer and its precursor lesions but also as a tool for follow-up, because it is accurate, economical, and easy to perform. But it remains to be solved that the false negativity of the cytologic diagnosis is relatively high. Five hundred and sevently two cases of cytology specimens, confirmed by either colposcopic biopsy or cone biopsy, were studied among 15,844 cases which were submitted to the Department of Pathology, Chonnam University Hospital between October of 1982 and August of 1986. The results obtained were as follows. 1) The accuracy of the cytologic diagnosis was 69.9%, the false nagativity, 19.4% and the false positivity, 6.6%. 2) Among the causes of discrepancies between cytologic diagnosis and histologic diagnosis, error in cytology reading was the most frequent (57%), error in cell collection was the second frequent (43.7%), and error in biopsy location was the least frequent (5.3%). 3) Among the 38 cases of false positive diagnosis, the percentage of error in cytology reading was 82.3%, and that of error in biopsy location was 20.7%. Among the 105 cases of false negative diagnosis, the percentage of error in cytology reading was 50.5%, and the percentage of error in cell collection was 56.6%.
