Angiokeratoma circumscriptum is present at birth or early childhood and is an uncommon dermatosis characterized by papules and small nodules that may coalesce to form plaques. Histopathologically, there are varying degrees of hyperkeratosis, papillomatosis, and irregular acanthosis. In the papillary dermis, greatly dilated capillaries are observed, The acanthotic epidermis encircles the vascular spaces(blood cysts) where, occasionally, organized thrombi may be found. The use of pulsed-dye lasers to treat cutaneous vascular lesions is based on the theory of selective photothermolysis. We report a case of an angiokeratoma circumscriptum in an 48-year-old woman for whom the flashlamp pulsed tunable dye laser proved to be a highly successful means of treatment.

The role of GABA or glycine as an inhibitory neurotransmitter is well established, and GABAergic or glycinergic neurons appear to play an important role in the mammalian retinas. It has been reported that certain amacrine, bipolar, displaced amacrine and ganglion cells are consistently labeled with anti-GABA or anti-glycine antisera in the mammalian retinae so far, and it has been suggested that colocalization of GABA and glycine within the retinal neurons could be common in the mammalian retina by recent immunecytochemical and electrophysiological studies. This study was conducted to localize GABAergic and glycinergic neurons and to define whether GABA and glycine are colocalized within same retinal neurons of the rat retina by immunocytochemical method using anti-GABA and anti-glycine antisera. The results were as follows : 1. GABAergic neurons of the rat retina were amacrine, interplexiform, bipolar, displaced amacrine and ganglion cells, and processes of GABAergic neurons formed dense networks with distinct two bands in the inner plexiform layer. 2. Glycinergic neurons were amacrine, bipolar, displaced amacrine and ganglion cells,and their processes were evenly distributed as dense networks through whole inner plexiform layer. 3. 28.5% of GABA immunoreactive amacrine cells and 9.8% of GABA immunoreactive bipolar cells located in the inner nuclear layer,and 11.9% of labeled neurons located in the ganglion cell layer showed glycine immunoreactivity in the rat retina. These results demonstrate that GABA and glycine, major inhibitory neurotransmitters, are colocalized within certain amacrine and displaced amacrine cells, and a few bipolar cells, and that neurons synthesizing and utilizing both GABA and glycine as their neurotransmitters may play an unique role in the visual processing in the rat retina.

Atopic eczema (AE) is a chronic, inflammatory skin disorder which usually develops in early childhood. In spite of intensive investigations, the causes of AE remain unclear, but are likely to be multifactorial in nature. Environmental factors or genetic-environmental interactions seem to play a key role in disease progression. Among various measures of AE managment, cutaneous hydration, which improves barrier function and relieve itchiness, may be helpful to reduce the need for topical steroid use and therefore should be used as a basic treatment. Avoiding aggravating factors is also a basic treatment of AE. Standard medical treatment with a pharmacologic approach may be necessary if basic treatment fails to control symptoms satisfactorily. Recently, more attention is given to a proactive therapeutic by regular intermittent application of low potency steroids or topical calcineurin inhibitors to prevent new flares. Furthermore, various targeted biologics are being introduced for AE control and are proposed as promising therapies. This paper provides a summary of the recent literature on the manangement of AE and a treatment guideline.

Favre-Racouchot syndrome is a disease of senile or actinic processes and another name is nodular elastosis with cysts and comedones. Clinically, facial skin shows, especially lateral to the eyes, multiple open and cystically dilatated comedones and can be defined as cutaneous disturbances characterized by a degenerative process of the dermis associated with cysts and comedones. Sunlight is a strong causative factor and dermal degenerative processes result in this condition. We report the case of a 78-year-old man who showed multiple yellowish papules on both sides of cheeks, the periorbital and, malar areas. He had had this condition for 25-years. His job used to involve physical labor and much exposure to sunlight. An excisional biopsy specimen from the facial malar lesion showed cystically dilated comedones with basophilically degenerated dermal tissue. We performed a therapeutic excision on the two large nodular lesions on both malar areas and applied topical tretinoin. The Patients clinical appearance was much improved 2 months later.

A 51-year-old Korean woman presented with a non-tender, well-demarcated, reddish, edematous patch on the right anterior chest where a previous mastectomy and radiation therapy had been performed. She had been diagnosed as having infiltrating ductal carcinoma of the right breast about 1 year ago. Histopathological findings of the skin lesions were consistent with inflammatory metastatic carcinoma of the breast. Inflammatory carcinoma or carcinoma erysipeloides is a well-established entity most frequently associated with carcinoma of the breast. It is characterized by dermal lymphatic invasion by malignancy and clinically should be distinguished from erysipelas or cellulitis. We describe a case of inflammatory metastatic carcinoma derived from an infiltrating ductal carcinoma of the breast which can be clinically confused with radiation dermatitis.
