In order to study immunological responses in psoriatic lesions, direct immunofluorescence(DIF) findings in stratum corneum of psoriatic lesions are compared with histopathological changes. The results are summerized as follows: 1) Deposition of Igs or C 3 in stratum corneum of psoriatic lesions was demonstrated in 14(56%) of 25 psoriasis patients. IgG was present in 40% IgA in 48%, IgM in 24%, and C 3 in 32%. However, DIF findings are negative in the str,atum corneum in the uninvolved skin of psoriasiis. In control groups of 12 cases of various skin diseases, DIF findings were negative in the stratum corneum except 1 case of a patient with acne rosacea. 2)DIF findings in 22 cases of histopathologic changes of psoriatic lesions were found in 50% of hyperkeratosis in 48% of parakeratosis in 50% of Munro microabscess, in 50%, of spongiform pustule, and in 57% of the absence of stratum granulosum: ie, about only 50% were positive in DIF results. Histopathologic changes in 11 cases of positive DIF finding in psoriatic lesions were hyperkeratosis in 100%, parakeratosis in 91%, Munro microabscess in 64%, spongiform pustule in 55%, and the absence of stratum granulosum in 73%.

This is to describe a neonatal hepatitis with pericellular hepatic fibrosis and Mallory bodies in a sero-positive infant for IgM anti-CMV. A necropsy of the liver revealed severe heaptocellular swelling with many intracytoplasmic hyaline bodies, pronounced fibrosis of a creeping type, bile stasis with ductular proliferation, and the lack of parenchymal regeneration. These microscopical changes of the liver resembled those of Indian Childhood Cirrhosis (ICC). In the present case the patient's serum IgM anti-CMV is the only clue for the etiological diagnosis.

Amyloidosis is a disease complex associated with deposition of inscluble fibrillar protein in vnrious tissues of the body. Since the term, amyloidosis was first introduced by Virchow in 1853, there have been many reports in English literature, but only a few cases of iriinary systemic amyloidosis have been reported in Korea. A 56-year-old male was seven for facial purpuras, macroglossia, myilgia and arthralgia for 5 years. Histologically, the skin biopsy specimen showed amorphous, faintly eosinophilic and fissured masses of amyloid in the upper dermis that demonstrated characteristic green brefringence on Congo red staining when viewed under polarized light. Electron microscopic exanintion showed that nonbranching and nonanastomosing straigh. fibrils are irregularly arranged arouned tlie collagen fibers. Therefore, he was diagncsed with primary systemic amyloidsis by the characteristic clinical, histopathologic and ultrastructural findings.

Congenital melanocytic nevus(CMN) constitute a well-known risk factor in the development of malignant melanoma, but melanoma developing in newborn and infants are extremely rare. We describe a case of proliferating nodules within CMN at the age of 13 months. Like our case it is difficult to manage the proliferating lesions within CMN in infants. So we carefully suggest the indications of preventive excision when proliferating lesions occur within CMN as follows; 1) preventive excision is postponed until the age of two when the proliferating lesions are slowly growing, 2) surgical excision is needed when the lesions are rapidly growing exceeding 1 cm in size even though it is before the age of two.

Evidence of antigenicity of testis and semen has been presented since Landsteiner (1899), Metchinikoff (1900) and Metalnikoff (1900) first demonstrated the induction of a spermatoxic antibody in animals sensitized with testicular homogenates or semen. Interest in the field of male accessory sex gland began longtime ago, when the first cross-reaction between extracts of prostate, seminal plasma were demonstrated. Saline extracts of prostatic secretion from bulls, tested by double agar diffusion technique showed four antigens common to serum proteins and spermatozoa. The seminal vesicle have been found to have three to five antigens, also with common reactivity to spermatozoa. Attempts have been made to induce cross-immunologic damage in the testes by repeated immunization of mice with epididymal extracts (free of sperm) plus adjuvant and it was claimed that spermatogenesis was adversely effected and fertility of females was markedify reduced following mating with immunized male (Shethye and Rao, 1968; Kim and Kim, 1982). Rabit antiserum produced against the tissue protein of rat epididymis and seminal vesicle was capable of immobilizing and agfflutinating the sperm of both animals and the rabbit antiserum against complex antigen of epididymal tissue protein and seminal vesicle tissue protein of rat was most potent on sperm immobilization and agglutination of both animals (Cha and Kim, 1975). The purpose of this study is to observe the effect of rabbit anti-rat epididymal serum on epididymis and spermatogenesis in rat. The results were as follow; 1. The intraluminalspermatozoa of epididymis were decreased in number but immature sperm cells were much more noted than normal control group. The interspaces of epididymal ducts were widened and infiltrated with mononuclear cells and congestion in some places. There was no definite degenerative changes on epididymal epithelium. 2. Spermatogenesis was mildly to moderately impaired in the experimental group whereasit was unaffected in the control group. Degeneration and exfoliation were found in the germinal cells of seminiferous tubules. Intraluminal Spermatozoa of seminiferous tubules were decreased in number.

Large cell neuroendocrine carcinoma (LCNEC) of the lung is a newly recognized entity of pulmonary neuroendocrine carcinoma. Histologically, it is very difficult to differentiate LCNEC from other pulmonary carcinomas and the prognosis is significantly poor. The cutaneous metastasis of LCNEC of the lung shares some features with Merkel cell carcinoma of the skin in light microscopy and yet it is negatively stained with cytokeratin 20. We report a case of cutaneous metastasis of LCNEC of the lung, previously misdiagnosed as squamous cell carcinoma. Our patient showed a poor response to the chemotherapy and also revealed a brain metastasis on follow-up brain CT scan.
