BACKGROUND: Morphologic characteristics of the human embryonic and fetal periderm according to body region are not very clearly defined. OBJECTIVE: We have tried to Clarify the sequential development of periderm regionally. METHOD: Skin samples were obtained from 12 human embryos and fetuses ranging from 4 to 23 estimated gestational ages(EGA) and divided regionally into scalp, face, back. abdomen, thigh and sale. Specimens were observed by scainning with an electron microscope. RESULTS: Human embryonic end fetal periderm show distinct morphologic changes as follows along its own sequence of development flattened surface, elevated surface, fiormation of incomplete bleb. single bleb stage, multiple-complex bleb stage, formation of regressinjg bieb. Then towards the end of the second trimester, most of thieperidermal cells are completely regressed. Regional variation in peridermal development is not evide!nt during the embryonic period, but earlier development is apparent in the sole, face and scalp especially in the sole compared to other areas during the late first snd second trimester after EGA 9 weeks. CONCLUSION: The periderm, which can be seen only in embryonic and fetal epidermis, shows distinct sequential developmental changeis with regional variation.

TO evaluate the histopathologic features of gastric mucosa by Helicobacter pylori (HP), we reviewed 70 endoscopically biopsied chronic gastritis and peptic ulcer. The results are as fonows. l. HP was detected in 923% (48/52) of active gastritis, 8l8% (9/l l) of peptic ulcer and l43% (1/7) of chronic gastritis. The prevalence of HP infection was significantly higher in active gastritis and peptic ulcer than chronic gastritis (P<0005). 2. The infiltration of intraepithelial neutrophil of the 58 HP-positive cases was significantly more than of the l2 HP-negative cases (P<0005). 3. The infiltration of neutrophil and chronic inflammatory cells in the lamina propria of the 58 HP positive cases were significantly more than of 12 HP-negative cases (P<0.005, P<0.01) 4. The gastric epithelium of 58 HP positive case showed characteristic degenerative change, such as epithelial pits (93.l%), irregular surface (84.4%), individua1 cell drop-out (46.5%) and microerosion (27.6%). The similiar changes were not seen in l2 HP-negative cases. In summary, HP is significantly correlated with inflammatory reaction of the gastric mucosa. It is also significantly correlated with the epithelial degenerative changes that is considered to the precursor of peptic ulcer.

Pseudoatrophoderma colli is a symptomless, persistent, persistent, pigmentary disorder involving the neck and upper thorax first described by Becker and Muir in. 1934 The lesion is usually localized to the neck and upper part of the thorax. It consists of macules or papules which show pigmentation or papules which show pigmentation or depigmentation and look atrophic. Histological examination shows hyperkeratosis, hypogranulosis, focal acanthosis and perivascular lymphocytic infiltration. We present herein a case of pseudoatrophoderma colli which showed symptomless, mottled, pigmentated macules involving the neck clinically and compatible findings histopathologically.

A retrospective study was made of the previous medical records of 47 infants with congenital syphilis born from mothers with untreated syphilis at Severance Hospital, Yonsei University College of Medicine during the years 1972 through 1983 The VDRL titer of these infants was higher than 1: 8 with reactive FT.A-ABS test. They were subjectd to hematologic examinations and the results were as follow s, 1. Of 46 infants with congenital syphilis, anemia was observed in thirty-one (68%) Reticulocytosis occurred in seventeen(89%) of nineteen infants with congenital syphilis having the mean value of 6. 0%. 3, Of 4.7 infants with congenital syphilis, leucocytosis was noted in seveenteen 4, Thrombocytopenia was observed in twenty (64%) of thirty-one infants with congenital syphilis.

It is well estabilshed that the xerosis is closely related to diabeic pruritus. Although the causes of xerosis are thought to bie the abnormalities of sweating and autonomic nervous system, the exact mechanism of the xerosis in diabetic skin is still unknown. This study was designed to investigate the possible derangement of glucose metabolism in the skin of diabetes mellitus patients with xerosis. The epidemal glucose content and hexokonase activities were masured in the skin samples obtained from normal individuals and diabetes mellitus patients with xerosis The epidermal glucose content was measured by the enzymatic cycling method. The enzymatic activities of hexokinase were assayed by fluorometric method. The epidermal glucose content of diabetic patients increaed approximately twice [27.46+9.52 (mmole/kg /dry weight) that of normal individuals [13.90+4.79(mmole/kg /dry weight)] (p<0. 0001). The epidermal hexokinase activities of diabetes patients were significantly decreased [0.56+0.15(mole/hr/kg/dry weight)] compared to that of normal indivduals [0.96+0.24(mole/hr/kg dry weight)] (p<0.0001). There were no significant differences in the epidermal glucose content and enzyme activities of hexokinase between the diabetic patients with: erosis and diabetic patients without xerosis. These data indicated that decreased activities of hexokinase could reduce the glucose phopkiorylation and uptake into keratinocytes, and which could lead to accumulat. glucose in the interstitial space of diabetic epidermis. And the decreased hexokinase activities may exert on lipid metabolism and glycolysis of diabetic epiidermis, because hexokinase is a key enzyme of hexose monophosphate pathway and glycolysis.

We report a case of xanthelasma palpebrarum (XP) with bilateral extensive and disfiguring involvement of all four eyelids. The patient was a 28-year-old woman and noticed this condition eight years ago. Physical examination showed yellowish flat topped bilateral extensive plaques around the eyes. Laboratory result was remarkable for a decrease of a serum high density lipoprotein cholesterol (HDL-C). Other laboratory findings were within normal limits. Histopathologic findings showed diffuse infiltrations of foamy cells, histiocytes and foreign body giant cells in the dermis. Electronmicroscopic examination showed that the dermal infiltrate was composed of lipid laden histoncytes showing multiple villi which indicated an activated state of histioncyte. Bilateral and extensive XP is very rare. Only two cases have been reported in the literatures as far as we know.

A retrospective study was made of the previous medical records of 32 infants with congenital syphilis borne from mothers with untreated syphilis at Severence Hospital, Yonsei University College of Medicine during the years 1,972 through 19g3, These infants had a VDRL titer higher than 1: 8 with reactive FTA-ABS test and were also subjected to radiologic examinations. Radiologic changes and clinical features were analyzed, The following results were obtained: Of the total of 32 infants with congenital syphilis under 5 months of age, those under 1 month of age, were the most common group numbering a total of twelve. Of 32 infants with congenital syphilis, twenty-nine(91%) showed skeletal changes upon radiologic examination, Among them the different sites of bone involvernent revealed that the femur(92%) was the most commonly affected bone, followed by the humerus(88%), tibia(81%,), fibula(80%), ulna(72%), radius (68%). Among the same 29 infants a study of the presence of various abnormal bone changes showed that periostitis was the most common, being involved in 83%, the others being metaphysitis and periostitis(72%), metaphysitis(66%). 3. Among the clinicaI features presented in the 32 infants with congenital syphilis, hepatomegaly was the most common(63%,), followed by erythema with desquamation(47%), pneumonia(38%), maulopapules(34%).

Generalized granuloma annulare is a rare skin disease presenting generalized eruption with a distinctive histologic picture. The age of onset of generalized granuloma annulare differs from that of localized granuloma annulare. Most of the patients with generalized granuloma annulare were in the fifth to seventh decades and cases of generalized granuloma annulare in infancy or in early childhood have been rarely reported. We herein report two cases of generalized granuloma annulare in 45- and 18-month-old boys, who is the youngest patient yet reported in the Korean literature. The histopathologic findings were compatible with granuloma annulare and all lesions completely involuted in two months after administration of topical or systemic corticosteroids.

A 26-year-old female presented herself to our clinic due to noduloulcerative lesions of one month duration on her face and trunk with accompaning headache and mild fever. In family history, her husband was reported to have a history of chaner. On physical examinat.ion, rice sized eythematous papules and bean sized nodules with central ulceration were seen on the face and trunk. VDRL was 1:31 positive. A skin biopsy iif a noduloulcerative lesion showed ulceration, vascular dilatation with fibrinoid changes and perivascular inflarnmatory cellu infilt.rations, especially plasma cells. Immunoperoxidase stain showed T. pallidum at the epidermis and papillary dermis. The diagnsis was made asecondary syphilis with unusual clinical presentation as noduloucerative skin lesions. The skin lesions completely disappeared one month after treatment with injection of benzathine pelnicillin G 2.4 million unit intramuscularly weekly for three times.
