Many articles concerning the accuracy of diagnosis of malignant tumor cells in body fluids have appeared in the literature, but few authors have attempted to describe the characteristics of these cells to determine the site of the primary tumor as they relate to tumors of specific primary sites. This paper presents the results of a retrospective study on malignant body cavity effusions of which the primary site was established on the basis of either biopsy or surgical resection of the primary neoplasm during the period of 6 years beginning from January 1983 to December 1988. The results obtained are summarized as follows: 1) The 143 fluid specimens from 129 patients were composed of 51 cases of pleural, 69 of peritoneal, and 9 of pericardial origin. 2) Adenocarcinoma was the most frequent type of malignant effusions (78.3%). The most common primary site was the lung (50%) in pleural fluid and stomach (55.2%) in ascites. 3) The results of this study show that the primary site of tumor cells can be identified in the body fluid of accurate cytomorphologic criteria are used. Identification of the primary site of an effusion would be improved by the consideration of clinical information

The study was made in order to investigate the minimal inhibit concentration (M.I.C) to Trichophyton(T.) gypseum and Trichophyton rubrum by same salt solution(ie: NaCl, KCl and Sodium thiosulfate). The stanis were obtained at the out-patient clinic of Seoul National University hospital. The results are as follows: 1. The M.I.C. of NaCl manifest 10%, and Trichophyton rubrum shows more higher than that of T. gypseum. 2. The M.I.C. of Sodiurn thiosulfate manifest 10%, and T. gypseum shows more higher M.I.C. than that of T. rubrum. 3. The M.I.C. of KCI manifest 15% for T.rubrum and shows 20% for T. gypseum.

Mucous gland adenoma, one type of bronchial adenoma, is first introduced by Rosenblum and Klein2) in 1935 and very rare. Only twenty-one cases had been reported in english literature. This tumor must be differentiated from other types of bronchial adenoma because of completely benign clinical course. A case of mucous gland adenoma is presented which showed marked secondary calcification.

Skin wart is an infectious disease of human papillomavirus(HPV). Its clinical and histopathologic characteristics are largely determined by lesion sties, viral type and host immunity. The infected basal cells and keratinocytes of the epidermis are induced to proliferate by the viral genome. It is, however, not well known how htose factors give rise to histopathologic alterations in the infected basal cells and keratinocytes. So, evaluation of correlation between HPV antigen expression in the wart tissues and clinical and histopathologic charateristics was done on 83 cases of skin warts. The age of patients ranged from 2 to 83 years. Thirty six(43.3%) cases were diagnosed before the age of third decade. The sex ratio was nearly same. Verruca vulgaris was most common(46 cases), followed by verruca plana(26 cases) and verruca palmoplantaris(11 cases). HPV antigen expression was observed in 43 out of total 83(51.8%). It was noted in 47.8%(22/46) of verruca vulgaris, in 46.2%(12/26) of verruca plana and in 81.8%(9/11) of verruca palmoplantaris. HPV antigen-positive groups included more younger patient's age and more higher PCNA than those of HPV negative groups. HPV positive groups also tend to have shorter duration of disease and more numerous mitoses than HPV negative groups. HPV antigen-positive groups showed lower inflammation grade than that of HPV negative groups(p<0.05). The higher the inflammaton grade is, the lower the HPV antigen expression rate. In summary, HPV antigen expression in cutaneous wart tissue is significantly correlated with the proliferative activity of the lesion. It is also significantly correlated with the inflammation that is considered to be the result of cell-mediated immune reaction.

A clinical and histological study of typical sebaceous epithelioma (basal cell epitheioma with sebaceous differentiation) developed secondarily in lesions of nevus sebaceus of Jadassohn is presented. The patient was 42 years old male. The sebaceous epithelioma tends to have about the same clinical characteristics as undifferentiated basal cell epithelioma but it is more often a yellow color. Sebaceous epitheliova may arise from nevus sebaceus and it is preursor of undifferentiated basal ce]1 epithelioma. Histological]y, the preparation showed massive development of sebaceous gland, papillomatous epidermal hyperplasia and maturation of apocrine glands. The tumor cell nests were mostly composed of large sheets of irregularly shaped cells in palisading pattern at the periphery. There were Iarge number of cells with vacuolated cytoplasm resembling sebaceous cell in certain part of the tumor cell masses and several keratin pearls. Diagnosis confirmed by clinical appearance and histological picture. These lesions could be treated sucessfully by wide excision.

Pulmonary adenocarcinoma of fetal type is a very uncommon tumor of the lung which simulates an early stage of lung differentiation. This is a primitive appearing epithelial tumor similar to the epithelial component of pulmonary blastoma but lacking the sarcomatous features. Since the report of Kradin et al, 8 more cases have been reported by a variety of name. These tumors are composed of glycogen-rich, non-ciliated tubular epithelial cells forming irregularly shaped tubules or arranged in a papillary pattern. A very remarkable findings of this tumor is the presence of endocrine cells which is confirmed by argyrophilia, immunohistochemistry or electron microscopy. We experienced a case of this tumor which showed hepatocytoid differentiation in addition to the characteristic histologic findings. Immunohistochemical studies performed on a resected tumor tissue showed immunoreactivity for alpha-fetoprotein, neuron-specific enolase and somatostatin, and endocrine type granules were found ultrastructurally. Although this tumor seems to have a relation with pulmonary blastoma in its histology, immunohistochemistry and ontogeny, a distinction between these should be attained because the average survival of the former group is longer as 23 months, while that of the latter is only 4 months.

Fourteen cases of bowenoid papulosis were studied both clinically and histologically and were compared with 22 cases of Bowen's disease to find histologic differences between the two diseases. Bowenoid papulosis was prevalent in young, sexually active adults, consisted of multiple erythematous or hyperpigmented papules, and located mostly on the penis and vulva. The main histologic characteristics of bowenoid papulosis were an orderly background of keratinocyte maturation of the epidermis with monotonous pattern, the frequent presence of 'skip area', and the lesser degree of cytologic atypia than seen in lesions of Bowen's disease. In addition, mitotic figures more than 5 per x400 filed, formation of keratin pearl, and spindling of keratinocytes, which have not been described in other articles yet, are considered very important findings for the diagnosis of bowenoid papulosis. It is our opinion that bowenoid papulosis can be reliably distinguished from Bowen's disease by light microscopic features. Paraffin-embedded samples of bowenoid papulosis, Bowen's disease, and normal skin were investigated with antibodies against S 100-protein to relate the number of intraepidermal Langerhans cells and the disease. Langerhans cells were found to be reduced when compared with normal skin. No significant differences between Bowen's disease and bowenoid papulosis were found in density of Langerhans cells.
