We report an unusual case of sebaceous hyperplasia in an 18-year-old male manifestated clinically as yellowish, grouped papules with a linear distribution, present on the right side of forehead since birth. Histopathologically, a large sebaceous gland composed of numerous lobules grouped around a centrally dilated duct was seen. The sebaceous lobules distributed in the upper dermis showed direct connection to the skin surface, which suggested a transepidermal elimination of sebaceous lobules.

Menetrier's disease is characterized by enlarged gastric folds with foveolar hyperplasia and cystic dilatation of gastric glands. The additional biochemical features of hypoproteinemia, hypochlorhydria, and increased gastric mucus are often encountered. The pathogenesis and etiologic factors have not been clearly defined. In this report, we present two cases of Menetrier's disease in the stomach, one occurring in a 38-year-old male, associated with massive hematemesis, and the other in a 39-year-old male. Grossly, both cases showed marked giant gastric rugal folds resembling cerebral convolutions, sparing the antral portion. Microscopically, the giant gastric rugal folds consisted of the striking foveolar hyperplasia accompanied by an occasional presence of the smooth muscle fibers from the muscularis mucosa. The immunohistochemical stain revealed an intense positive reaction for transforming growth factor-alpha (TGF-alpha) and epidermal growth factor receptor (EGF-R) in the majority of mucous cells throughout the gastric mucosa and parietal cells, but did not reveal for epidermal growth factor (EGF). We suggested that TGF-alpha and EGF-R might be involved in the pathogenesis of Menetrier's disese.

The peripheral blood eosinophil and serum IgE level in 53 patients with atopic dermatitis (AD) were measured. The patients were divided into 2 groups by severity(mild and severe grous) and into 3 groups by the associated respiratory atopic deseases and/or their family history : respiratory group(patient, with both AD and respiratory atopy), family history group (patient with both AD and family history of respiratory atopy), and atopic group(patient with neither respiratory atopy nor family history of respiratorv atopy). We designed to study which factors are important in the elevation of serum IgE and peripheral blood eosinophil level in AD, and to know possible relationships between the serum eosinophil and IgE level and the several groups of AD. The results are as follows : 1. Peripheral eosinophil counts were higher in severe group(224.8/mm) than in mild group (180.0/mm)(p<0.05). 2. Peripheral eosinophil counts were 220.0/mm in atopic group, l65.0/mm in family history group, and 332.4/mm in respiratory group, but there was no stitistically significant difference among 3 groups. This suggests that concomitant respiatitiry atopy or a family history of respiratory atopy is not an important factor in the elvation of peripheral blood eosinophil counts in AD. 3. Serum IgE was higher in severe group(443.2IU/ml) than in mild group(231.5IU/ml)(p<0.05). 4. Serum IgE level in respiratory group(754.6IU/ml) were signifiiantlly higher than in atopic (286.6IU/ml) or family history group(342.0IU/ml)(p<0,01). But there was no significant. difference between family and atopic group. This result suggests that concomittent respiratory atopy is a potential factor in elevation of serurn Igi in AD. 5. Slightly high correlation between peripheral blood and IgE level appeared in all 53 patients (r=0.434) and severe group(r=0.480). But, respiratory group(r=0.060), family history group(r=0.111) and atopic group(r=0.202) showed poor relationships.

Recent investigations have revealed that autocrine growth factors and their receptors are closely related and play an important role in controlling cancer cell growth. We performed an immunohistochemical study on the expression of epidermal growth factor (EGF), transforming growth factor-alpha (TGF-alpha), epidermal growth factor receptor (EGF-R), c-erbB-2, and PCNA labelling index in 60 cases of human gastric carcinomas. TGF-alpha was detected in 38 cases (63.3%), EGF in 26 cases (43.3%), EGF-R in 44 cases (73.3%), and c-erbB-2 in 18 cases (30%). These growth factors, EGF-R and c-erbB-2, were found more often in advanced gastric cancers. The PCNA labeling index was significantly higher in tumors with the expression of EGF-R or c-erbB-2. Tumors with simultaneous expression of EGF, TGF-alpha, EGF-R and c-erbB-2 was associated with a high PCNA labeling index. A correlation was observed between the synchronous expression of growth factors and its receptors and histological differentiation. The results suggest that the expression of EGF, TGF-alpha, EGF-R and c-erbB-2 are closely related and plays an important role in the growth and progression of human gastric carcinoma.

Glomangiosarcoma is a histopathologically defined extremely rare malignant tumor that accompanies a glomus tumor usually, but its has benign clinical course characteristically. It shares common ultrastructural and immunohistochemical features with glomus tumor, and transformed possibly from glomus tumor". Glomangiosarcoma shows more sarcomatous appearance histologically than glomus tumor, however with no malignant behavior(i.e. recurrence or metastasis) was expressed. We experienced a case of glomangiosarcoma form subungual region treated by marginal excision and no recurrence or metastasis was developed untill 1 year and 6 months postoperatively.

Adenoid basal cell tumor of the prostate is a rare tumorous lesion that can be misdiagnosed as adenocarcinoma of the prostate. The malignant potential of adenoid basal cell tumor remains uncertain due to small number of reported cases. This 66-year-old man presented with symptoms of urinary tract obstruction. Under the impression of benign prostatic hyperplasia, a transurethral resection of the prostate (TURP) was performed. The patient was alive with no evidence of recurrence or metastasis 15 months after TURP. Microscopically, most of the lesions were composed of nodular collections of small nests of basaloid cells with peripheral palisading, and clusters of tumor cells forming cribriform pattern. Multiple areas of basal cell hyperplasia and atypical basal cell hyperpalsia were also observed. The coexistence of basal cell hyperplasia, atypical basal cell hyperpalsia, and adenoid basal cell tumor with cribriform pattern in this case supports a morphologic continuum from the benign hyperplastic lesion to malignant neoplasia.

A case of contact dermatitis due to herb onintment is described in a 24 year-old female patient. After topical application of herb ointment, she developed erythematous papules and plaques on the face and neck. Patch test revealed positive reactions to ammoniated mercury, thimerosal, and the herb ointment. Energy-dispersive X-ray microanalysis of the herb ointment showed a striking peak for mercury.

Primary meningeal melanocytoma of the central nervous system is extremely rare. We report a case of meningeal melanocytoma associated with Ota's nevus as a recurrent form in a 53-year old male. The meningeal melanocytoma was removed from right parietooccipital lobe 4 years ago and recurred in right parietal, occipital and left frontal lobes. Ultrastructurally, the tumor cells were characterized by the presence of numerous melanosomes and premelanosomes in their cytoplasm. Moreover, the tumor was lacking in histologic and ultrastructural features of pigmented meningioma, melanotic schwannoma and prolonged clinical course was different from primary meningeal melanoma or metastatic malignant melanoma.

Changes of power spectrum of R-R interval variabilty during recovery from N2O-O2 - halothane anesthesia have been studied in 20 patients. Power spectral analysis of R-R intervals during awake period and recovery period have been performed with newly developed R-R interval variability, we compared the power of each frequency range(low: 0.04-0.08 Hz, middle 0.10-0.15 Hz, high: above 0.3 Hz) between awake period and recovery period. There was no difference between awake period and recovery period in the power of low and high frequency ranges, but there was remarkable difference in power of midfrequency range. During awake period the power of midfrequency range changed with cyclic pattern, but there was no cyclic change during recovery period even after the regain of consciounss(30+/-3.2 min.). The power of midfrequency range during recovery period began to change with cyclic pattern only after 45 minutes. It is concluded that the power of midfrequency range is useful index of recovery from N2O-O2 -halothane anesthesia.
