Cutaneous horns of the penis are rare. We report a case associated with squamous cell carcinoma in a 56-year-old male. A gradually enlarging nodule had been on the glans penis for four years. He had suffered from an erythematous crusted tumor mass and horny excrescence on the glans penis which recurred and was aggravated after excision of the nodule seven months ago. Histopathologic findings of the lesions showed characteristic findings of squamous cell carcinoma and cutaneous horn. In situ DNA hybridization for human papillomavirus types 6, 11, 16, 18, 32, and 33 were all negative. The tumor mass were surgically excised and we have not found any sign of recurrence since then.

Pretibial myxedema, which consists of localized cutaneous accumulations of acid mucopolysaccharides, oceurs in a few patients with hyperthyroidi';m after its correction by surgery or radioactive iodine therapy. We report a case of pretibial myxedema with exophthalmos in a 36 year old male. He has suffered from hyperthyroidism with bilateral pretibial myxedema for a period of 4 years. He was treated with a subtotal thyroidectomy and excision of both pletibia lesions 1 year ago. The lesions recurred on t,he left pretibial area, as a 11 X 16cm sized, non pitting, non tender, swollen, brownish plaque. The histopathologic findings showed epidermal hyperkeratosis and a considerable arnount of mucin in the mid-dermis. We treat.ed him with intralesional injection of triamcinolone acetonide with marked improvement.

BACKGROUND: Recently, inireaing numbers of chemotherapeutic agens are being used to treat cancer patients. Mucocutaeous complications are commonly sen in association with the administration of these medicaticins. OBJECTIVE: We conducted a study in cancer chemotherapy patient so determine the suspected chemotherapeutic agents ancl frequency of various mucocutaneous side effects in these patients. METHODS: The study involved 140 patients admitted from Decerrae 1993 to September 1994 for cancer chemot herapy at Korea University Guro Hospital. RESULTS: The mucocutaneous side effects during chemotherapy were alopecia(55%), hyperpig mentation(32.9%), stomatitis(20%), phlebitis(12.9%), flushing(8.6%) descending order. Visual grade II, IV alopecia patients were most common, but as the chemot retpy cycle increased so, the severer the alopecia. Although the onset of the alopecia were variake many patients experienced alopcia within 17 to 24 days after the start of chemotherapy. Serpeitie supravenous fluorouracil hyperpigmentation were commor,(17.9%), Diffuse and longitudinal or horizontal band like nail pigmentation were observed, and, pigmented macules were also observei, epecially on the palms and digits. Stomatitis usually developed within 10 days after the start of chemotherapy and it persist ed for about 7 days and the most of the lesions were resolved spor Laeously. Other clinical manifestations accompanied with chmotherapy were tinea infection(16.4%), acne(7.1%), oral thrush (7%), white nail band(4.3%), pruritus(2.9%) in descending order. CONCLUSION: So, physiciars need to be aware of the widely divergnal cutaneous reactions which may occur with the use of antiancer medications.

Twenty-nail dystrophy is an idiopathic nail dystrophy in which all twenty nails are uniformly and simultaneously affected with excess longitudinal ridging and loss of lustre. The pathogenesis is controversial, and the treatment is unsuccessful. It is thought to have a self-limiting and reversible nature when it develops in childhood, but in adults, it is unusual and exists persistently. We re-port here two cases of adult patients with dystrophy of all twenty nails, whose ages were 58 and 55. The disease had been present for one year and may be associated with alopecia areata in the 58 year old and an idiopathic condition in the 55 year old. Negative results were obtained on mycological studies. Biopsies taken from the nail bed revealed marked hyperkeratosis consistent with nail dystrophy.

A case of a 21-year old female with Maffucci's syndrome is presented where the patient developed multiple cutaneous spindle-cell hemangioendotheliomas. She had multiple pea to walnut sized, non-tender, normal skin colored or slight bluish nodules and bony mass-like lesions on the left upper extremity and hand. A histological examination of the lesions showed that they were composed of irregularly dilated, thin walled cavernous blood spaces containing phleboliths and collapsed vascular spaces separated by spindled fibroblastic cells. Radiologically, the bony lesions showed radiolucent densities with calcified spots within the second proximal phalanx and metacarpal bone of the left hand, which were consistent with enchondromas.

We report a case of infantile digital fibromatosis in a 34 month-old boy, who presented with a painless subcutaneous tumor on the medial aspect of the left third toe. A histological examination showed scattered small, round eosinophilic inclusion bodies in the cytoplasm of the tumor cells, which was consistent with infantile digital fibromatosis. A'immunohistochemical study revealed that desmin, a-smooth muscle actin, and vimentin were clearly positive in the cytoplasm of the tumor cells, but the inclusions themselves showed negative staining, thus indicating a hollow-like staining pattern. Electron microscopy showed either well-defined or ill-demarcated dense bodies in the cytoplasm of the tumor cells. In some areas, small vesicles and intracellular organells were observed' in the inclusions. In the course of conservative treatment, a new lesion developed on the lateral aspect of the left third toe, seven months after the appearance of the initial lesion.

BACKGROUND: The keratinocyte growth factor(KGF) is a recently identified mitogen for epithelial cells produced by nomal stromal fibroblasts. ln the skin, KGF has been shown to stimulate keratinocyte proliferation and differentiatian. Dendritic epidermal T cells(DETC) are skin-specific members of the epithelial y 8 T-cell family that reside normally in the murine epidermis. The DETCs recognize antigen expressed by damaged or diseased neighboring keratinoctyes and consequently secrete cytokines sueh as IFN- y, lL-2, IL-4, GM-CSF. OBJECTIVE: The purpose of this study was to observe the expression of KGF mRNA in keratinocyte and DETC as well as to investigate the cytokine-mediated intercellular communication between kerati- nocyte and DETC. METHODS: Using a RT-PCR(reverse transcription-polymerase chain reaction), we examined the expression of KGF mRNA in keratinocyte and DETC, and compared the level of KGF mRNA between resting and activated DETC with Con-A (concanavalin A).

BACKGROUND: The regular use of soaps and synthetic detergents has been associated with skin dryness and aggravation of dermatological conditions. OBJECTIVE: Our purpose was to investigate the irritancy of 10 hand dishwashing liquids on normal skin. METHODS: The skin changes, responding to repeat patch testing with 10 hand dishwashing liquids, were measured by visual scoring. RESULTS: The results are summarized as follows; 1. Of the 16 healthy volunteers 8 had reactions. 5 women and 3 men, but there was no significant difference in irritancy between men and women. 2. The mean irritancy scores of the 10 hand dishwashing liquids ranged from 0.06 to 0.88. 3. A prominent increase in the degree of erythema in the first 24 hour patch test did not persist beyond exposure day 5, but after day 5, augmented responses of the erythema and scales, even fissuring occurred. 4. The pH of the test solutions of the hand dishwashing liquids ranged from 5.0 to 6.0, but there appeared to be no correlation between pH and irritancy in the dishwashing liquids tested. CONCLUSION: Our data suggests that regular exposure to hand dishwashing liquids may cause disturbances of the skin in a substantial proportion of individuals, and workers should use hand dishwashing liquids in lower concentrations than recommended and only for short periods with protective measures.
