We report a case of a morphologic variant of dermatofibroma. A coin sized, brownish, shinny, somewhat fibrotic pedunculated tumor in a 39-year-old male was diagnosed as a sclerosing hemangioma, a type of dermatofibroma histopathologically. Its dome shape morphology was unusual in comparison with the typical morphology of dermatofibroma that we know.

Annals of Dermatology 1995;7(1):96-98
We report a pigmented follicular cyst (PFC) in a 40-year-old male manifestated clinically as pigmented nevus. Histopathologic findings revealed an infundibular cyst in the mid dermis containing a small amount of keratinous material. The cystic wall consisted of four or five layers of squamous epithelium with a granular layer with abundant keratohyaline granules and the cyst wall contained one hair follicle. It must be differentiated from other pigmented lesions of over-lying skin such as eruptive vellus hair cyst, apocrine hydrocystoma and melanocytic nevus coexistance of an epidermoid cyst. Surgical excision and histopathological examination are necessary for an accurate diagnosis in pigmented lesions.

BACKGROUND: Skin surtice lipids increase and decrease in tints with acne vulgaris and in patients with atopic dermatis, respectively. Notably, hydratior. in decreased in patients with atopic dermatitis. Clinically it is common for the two diseases to occur together. OBJECTIVE: We would like to find out the rate, clinical cteristics, and hydration and lipid levels when acne vulgaris and atopic dermatitis concur. METHODS: We classific the clinical levels and measured the hydration and lipid levels of the face and forearm area of patients with acne vulgaris, patients phatopic dermatitis, and patients with both diseases, who visited the Youngdong Severance Hospital. RESULTS: 1) 13.8% (14/102) of patients with acne vulgaris had at, epidermatitis. 31.1% (14/45) of patients with atopic dermatitis had acne vulgaris. 2) Patients with acne vulgaris had increased lipid levels and normal hydration levels. 3) Patients with atopie dermatitis had decreased lipid and iylration levels. 4) Patients withoth cnevulgaris and atopic dermatitis a no severe grade of acne vulgaris, and showed decreased hydration but normal lipid levels. CONCLUSION: In patients with both arne vulgaris and atoic dermatitis, clinically acne vulgaris was not severe and hydation levels were lower than normal controls.

In single atrial and ventricular cells isolated from the guinea-pig and the rabbit heart, action potentials and membrane currents were recorded by using the whole cell voltage clamp technique. In rabbit atrial cells the repolarization showed two distinctive phases, referred as the early and late phases(early and late plateau phase), but in guinea-pig atrial cells there was a maintained plateau and less distinctive two phases of repolartization. Increasing intracellular sodium or reducing external sodium by replacement with lithium suppressed the late phase of the action potential in rabbit atrial cells and shortened the plateau of action potential in rabbit ventricle and guinea-pig atrial cells. Reducing external sodium decreased Ca-current and late inward current in voltage clamp. Ouabain in the concentration of 10(-5)M shortened the duration of action potential and shifted the holding current level to outward direction, decreased Ca-current and moved late inward current to outward direction. Ryanodine 10(-6)M which is known to be an inhibitor of Ca-release in the intracellular store, suppressed the late phase of action potential in rabbit atrial cells and shortened the plateau of action potential in rabbit ventricular cells. Ryanodine also decreased Ca-current and shifted late inward current to outward direction. It is concluded that an inward current activated by intracellular calcium contributes to the late Phase of the action potential in rabbit atrial cells and to the late plateau in rabbit ventricular cells and in guinea-pig atrial cells. It may be carried by the Na-Ca exchange precess and/or by calcium-activated non-specific channels but preferably Na-Ca exchange machanism.

BACKGROUND: Primary hyperhidrosis is the disease of production of exessive sweat which is mainly localized in palm, sole, and axilla, treatment of the disease is usually accomplished with topical 20% aluminum chloride solution, an iontophoretic device, and surgery(sympathectomy) being reserved for recalcitrant cases. OBJECTIVE: We have compared the therapeutic effects with each treatments for hyperhidrosis using a skin surface hydrometer. METHODS: Thirty six patients(11 ; male, 25 ; femlale) with primary hyperhidrosis were evaluated in this study. Nineteen patients used topical 20% aluminum chloride solution, 10 patients used iontophoretic device, and 7 patients in recalcitrant cases. had sympathectomy. We have measured the conductance on the stratum corneum of the palm and sole suing skin surface hydrometer before and after treatment every weeks for a month. the control group were composed of healthy 10 males and 2 females. RESULTS: 1) In the patients of primary hyperhidroisis the conductances of palm, sloe and axilla were higher than that of control group(P<0.01). 2. There was a marked reduction of conductance after the treatment for one week by topical 20% aluminum chloride solution, an lontophoretic device, and sympathectomy(P<0.01). 3. After 2-4 week of treatment by the change obsetved after treatment for one week. 4. By iontophoretic device, there was a slight increasement of conductance of the palm after 2-3weeks of treatment. 5. We obseved a sustained decrease in the conductance by sympathectomy into 4 week. CONCLUSION: Topical 20% aluminum chloride solution, iontophoretic device, and sympathectomy were effective for treatment of hyperhirosis. Among hem sympathectomy showed the best effect. We observed that the skin surface hydrometer is useful to evaluate of the efficacy of the treatment.

Although reports have been assessed to locate lesions in the frontal lobe or anterior cranial fossa, the exact localization of the lesion is invariably difficult in neurological examination. However angiographic pattern is one of the most significant clue to the diagnosis of this area. For the past 2 years, from may in 1968 to December in 1970, we have analyzed angiographic patterns of space occupying lesion in the frontal lobe and anterior cranial fossa in a total of subsequent 100 cases. It is suggested that these lesions be classified into four groups according to their characteristic patterns and, for accurate localization and practical feasibility, their surgical approach. The characteristic angiographic patterns of each group are summarized as follows: (Frontal-pole) A-P view: 1. Round shift of A.C.A. 2. Flattening of carotid fork. 3. Elongation of AI. 4. No chekrein effect. 5. Sylvian point & M.C.A.... normal / (Fronto-central) A-P view: 1. Round shift of A.C.A.-mild. 2. Checkrein effect. 3. Depression of M1. 4. Flattening or mushroom appearance of carotid-fork. 5. Sylvian point... normal. / Lateral view: 1. Posterior displacement of A.C.A. 2. Vertical stretching of A2-A3. 3. Stretching of frontopolar artery. 4. Downward displacement of M2. 5. Depression of candelabra artery. 6. Closing of carotid siphon. 7. Ophthalmic artery... normal. / Lateral view: 1. Rectangular erection of C1-M1. 2. Right angle of C1-C2. 3. Elevation of M2-M3. 4. P.C.A. & ant. Choroidal artery... better. / (Fronto-lateral) A-P view: 1. Round shift of A.C.A. 2. Infrequent checkrein effect. 3. Flattering of carotid fork. 4. Vertical stretching of C1. 5. Sylvian point... normal. / Lateral view: 1. Mild stretching of A2-A3. 2. Continuous line of C2-M2. 3. Depression of M2. 4. Stretching of candelabra artery. / (Fronto-basal) A. subfrontal; A-P view: 1. Round or angular shift of A.C.A. 2. Flattening of carotid bifurcation. 3. No checkrein effect. 4. Sylvian point... normal. / Lateral view: 1. Bowing and downward convexity of A.C.A. 2. Closing of carotid siphon. 3. Depression of sylvian artery group. 4. Enlargement of ophthalmic artery. B. Inferior frontal; A-P view and lateral view: 1. Same as subfrontal lesions. 2. Relative preservation of A.C.A. branches. 3. Enlarged ophthalmic artery... mild. 4. Depression or elevation of M2.
