The diagnosis of carcinoma in situ of urinary bladder is difficult in that the symptoms and cystoscopic findings are nonspecific. The cytology of urine could be helpful for diagnosis of carcinoma in situ of urinary bladder. We present a case of bladder washing cytology of carcinoma in situ. A 54 year old man presented with dysuria for 1 year. Cystoscopic findings revealed multifocal reddish trabeculated lesions. The bladder washing cytology revealed rather uniform tumor cells which were singly scattered or forming syncytium in the clean background. The nuclei were round to oval with inconspicious nucleoli. The cystoscopic biopsy revealed typical histologic features of carcinoma in situ of urinary bladder.

We have reviewed ovarian mature cystic teratomas with features of chronic thyroiditis that were diagnosed at the department of pathology, Seoul National University Hospital during 7 years, 1984-1991. Twenty three case(8%) containing thyroid tissue among 285 ovarian mature teratomas were available for histopathologic examination. Among these, 4 cases(1.4%) showed lymphocytic infiltration with lymphoid follicle formation. These four cases were examined according to the strict histologic criteria of autoimmune thyroiditis and reactive non-autoimmune thyroiditis for the purpose of differentiation of pathogenesis. Two cases were similar to autoimmune in nature and the other two cases simply seemed to reflect reactive features to adjacent stimulating elements. In conclusion, thyroid tissue present in ovarian cystic teratoma may have histologic features of chronic thyroiditis of either autoimmune or non-autoimmune origin.

It is difficult to know whether the presence of infection in the plantar ulcer in patients with leprosy or not. Because routine bacteriology is often unhelpful, we need to investigate diagnostic method in this situation. C-reactive protein(CRF) levels have been known to be useful in detecting infection in some diseases. In this study, CRP levels were measured in 20 leprosy patients with plantar ulceration and 14 patients with leprosy alone. The results were as follows : 1. There was no elevation of CRP levels in patients with leprosy alone, and in the majority of patients with ulcers. 2. Of 20 patients with plantar ulcers, four had raised CRP levels one had clinically obvious infection, and three had erythematous skin of uncertain cause surrounding their ulcers. 3. Treatment with an appropriate antibiotics reduced CRP levels to normal, which was associated with clinical improvement. Therefore, it is suggested that increased CRP levels can be a useful probe for detecting significant bacterial infection in plantar ulcers of leprosy patients.

Epithelial-myoepithelial carcinoma of intercalated duct(origin) is a recently described tumor characterized by its typical biphasic pattern of central duct like cell and peripheral clear cell. We described a case of epithelial-myoepithelial carcinoma in a 10-year-old boy. Microscopically, the tumor showed typical biphasic pattern, diffuse proliferation of clear cells and linining epithelial cells of tubular structures. Immunohistochemically, the clear cell showed positive reaction to S-100 protein, and the epithelial cells expressed cytokeratin indicating myoepithelial and epithelial differentiation respectively. Biphasic differentiation of the tumor cells could be also proved by electronmicroscopic study.

Clinical study on 62 patients (26 males and 36 females) with neurofibromatosis seen during past ten years at the Department of Dermatology, Pusan National Universitg Hospital, was made the variable clinical manifestations of the disease and Riccardis ciassification were emphasized. The results were as follows . 1) Family history was noted in 32 cases(51.6%) and exhibited autosomal dominant inheritance pattern. 2) Cutaneous neurofibromas were found in 52 cases(83.8%). 3) Cafe-au-lait spots, measuring greater than 1.5cm in its longest diameter, were found in 60 cases(96.8%) and 44 cases(71.0%) had more than 6 in number. 4) Among associated abnormalities were,' mental retardation(20,9%), skeletal abnormalities(11.2%), seizure, severe headache, etc. 5) According to Riccardis classification, 38 cases could be classified as type I, 28 cases(73.7%); type II, 0 case ; type III, 1 case(2.6%); type IV, 3 cases(7, 9%); type V, 1 case(2.6%); type VI, 4 cases(10.5%); type VII, l case(2.6%); and type VIII, 0 case.

Involucrin is a recently recognized structural component of mature squamous epithelial cells and is considered as a marker of normal eratinocyte differentiation and ma.turation. In this study peroxidase-antiperoxidase techniques were used to assess involucrin expression in histologic sections of normal skin and a variety of epidennal tumors including squamous cell carcinomas(25 cases), keratoacanthomas(11 cases), basal cell carcinomas(20 cases), trichoepitheliomas(5 cases), Howens diseases(12 cases), arsenic keratoses(10 cases), actinic keratoses(10 cases) and Pagets diseases(2 cases). The results were as follows : l. In normal skin, the upper third of the viable epidermis showed diffuse cytoplasmic staining for involucrin. In hair follicles, the lower area of inner root sheath and inner area of the outer root sheath stained positively. The sebareous glands did not stain, but the ducts of sebaceous glands were positive. 2. Keratoacanthomas showed a relatively homogeneous staining pattern for inirolucrin ', all cells except basal cells stained with mild to moderate intensity. In contrast, squamous cell carcinomas disclosed a highly irregular involucrin staining pattern with marked variation in staining intensity from cell to cell. 3. Basal cell carcinomas were negative for involucrin except squamous horn cysts, and the epidermis overlying basal cell carcinomas showed the field effect, that is, the epidermis overlying the tumors exhibited diffuse, homogeneous positive staining of cells in all layers of the epidermis. 4. ln trichoepitheliomas, the involucrin reactivity was negative as in basal cell carcinoma.s, but the field effect was not observed. 5. In Elowens disease, actinic keratosis, arsenic keratosis and Pagets disease, the positivit.y for involucrin staining extended deeper into the stratum malpighii than was observed wit,h normal epidermis. And areas showing irregular patchy pattern of involucrin staining were considered to have the potentiality of malignant invasive change much more than the negative or homogeneous areas. Paget's cells were negative for involucrin as the adjoining keratinocytes in the lower portion af epidermis.

We report an autopsy case of the brain stem glioma that extended extensively in the brain stem itself and cephalad. This 18-year-old boy first presented with dizziness, vomiting and left side weakness with left facial palsy. Brain MRI revealed a diffusely infiltrative tumor involving whole medulla, pons and lower midbrain. A total of 4000 R was given with some alleviation of respiratory difficulty. He died one year after the onset. Autopsy revealed the tumor involving pons, a portion of medulla oblongata, and cerebellum. The tumor showed diffusely infiltrative pattern and extended along the periventricular area to the thalamus and corpus callosum. The cut surface was grayish white and solid. It also showed areas of myxoid degeneration and necrosis probably related to radiation therapy. Microscopically the tumor was a cellular and pleomorphic glioma that showed some astrocytic differentiation. It was diffuse without geographic necrosis.
