Recurrent infantile digital fibroma is a peculiar fibrous tumiir that may be single or multiple on fingers and toes of infants and children. We report a 5-year-old gril with recurrent infantile digital fiber oma which was recurrent on the left 5th toe. The lesion had noted at the age of 6 months. and was excised surgically when the child was 3 year old. 2 years after operation, the lesion was recurred in operation site. Microscopically, nodular fibrous mass is attached to flattened,pidermis. The underlying nodule is composed of proliferating fibroblasts surrounded by derse collagenous tissue. We could find eosinophilic inclusion bodies in the cytoplasm of fibro ilast. It was stained pink with H&E, bright red with Massons trichrome and purple with PTAH.

Trichost.asis Spinulosa consists of several fasciles of reta ned vellus hairs in the hyperkeratotic sebaceous follicles, resulting in a dark slightly raied horny follicular spines, resembling comedones on the trunk and face. The condition is relatively common, particulary among the age, but is usually overlooked on routine skin examination as the patient is rarely aware of it.. We report 6 cases of trichostasis spinulosa, which showed numerous asymptomatic tiny black comedo-like dots on their backs. We obtained the follicular material by tweezer, which consised of several vellus hairs surrounded by a keratinous plug. Histologic examination was done in 3 patients, one of whom showed a rarely reproted double follicle and double papilla. With scanning electron microscopy, we observed multiple vellu hairs embedded in a keratotic plug, emerging from a hair follicle opening.

BACKGROUND: Several reports have demonstrated that TGFalpha and EGF are mitogenic for keratinocytes. Whenther its expression on epithelial tumors is a marker of malignancy or signifies an important step in the development of neoplasia is poorly understood. EGF receptors are also present in normal epidermis and epithelial tumors but their physiological roles are not yet understood. OBJECTIVE: Our purpose was to examine the staining patterns of TGFalpha, EGF and EGF receptors on the npithelial tumors of the skin, and to investigate kinetics of expression of EGF receptors. METHODS: We performed immunoperoxidase staining(ABC technique) with monoclonal anti-TGFalpha antibody, polyclonal anti-EGF antibody and polyclonal anti-EGF receptor antibody on the formalinfixed, paraffin-embedded tissue specimens of benign, premalignant and malignant skin tumors. RESULTS: The density of the expression of TGFalpha and EGF was not correlated with the degree of the malignancy of the epithelial tumors and is neither constant in any kind of the tumors. However the infiltrative type of basal cell carcinoma(BCC) is stronger that its solid type on the expression of TGFalpha and EGF. All benign tumors demonstrated a diffuse pattern within tumor lobules. pression of TGFalpha and EGF. All benign tumors demonstrated a diffuse pattern within tumor lobules. Focal TGFalpha immunostaining was seen in three of 10 squamous cell carcinomas(SCC) and four of 10 BCCs. TGFalpha immunostaining was absent from the outermost one to two layers of tumor lobules of all keratoacanthomas. The specimens which increased the expression of TGFalpha and EGF tended to decrease the expression of EGF receptor. CONCLUSION: These data suggest that the density of immunohistochemical expression of TGFalpha and EGF may be not dependent on the differentiation of tumor cells, and the pattern of immunohistochemical expression of TGFalpha can differentiate SCC from benign tumors such as keratoacanthoma. FGF receptor may be occupied by both of TGFalpha and EGF. With the receptors being occupied, a down regulation of the receptors may occur which results in decreased EGF receptor expression.

Multiple factors including gastroesophageal reflux disease (GERD) were evaluated for a case-control study in Chonnam area to investigate the causative entity of COPD. Data on the multiple causative factors from hospital records and interview survey were analyzed in three groups of COPD(64 cases as case group), normal lung (83 cases as control group 1) and non-COPD lung disease (45 cases as control group 2). Smoking status, history of adulthood pulmonary infection and frequent history of URI, socioeconomic status, and GERD were significantly different between COPD group and control group 1. Drinking status, physical height of the subjects and GERD were significantly different between COPD group and control group 2. If control group 1 was used, odds ratio of GERD and COPD was 5.68(95%confidence interval, 95% CI:2.59-12.45) and 4.81 (95% CI:1.89-10.53) when adjusted by age and smoking status. If control group 2 was used. Odds ratio of GERD and COPD was 4.22 (95% CI:1.69-10.56) and 4.59 (95% CI:1.64-12.86) when adjusted by alcohol and adulthood respiratory infection status. In summary, there results suggested that GERD might play a causative role in the development of COPD.
