Benign odontogenic neoplasms are rare, but malignant odontogenic neoplasms are extremely rare. The majority of malignant epithelial neoplasms occurring in the jaws are the result of metastasis from distant primary neoplasms of direct invasion from contiguous carcinoma of the oral mucosa, sinus mucosa, salivary gland or skin. A few remaining primary intraosseous carcinoma of the jaw are presumed to be of mostly odontogenic origin since epithelial remnants of odontogenesis are numerous in the maxilla arts mandible. Although calcifying odontogenic cyst(COC) is a well-established pathologic entity, it has been recognized that there is an odontogenic neoplasm with histologic features similar to the COC(malignant epithelial odontogenic host cell tumor; EOGCT) that has been diagnosed as COC. Some authors have reported previously in the literature describing malignant EOGCT. We experienced one case of malignant EOGCT with aggressive growth pattern and histologic features strongly implying its malignant potential. The lesion was excised by anterior mandibular resection, total 1 resection of the tongue and bilateral functional neck dissection. The tongue was reconstructed by using the infrahyoid muscle neurovascular island flap and neurovascular radial forearm free flap. The mandible was reconstructed by using the osteocutaneous fibular free flap.

In 1968, Hardy and Anderson first described the term hypereosinophilic syndrome. This syndrome is characterized by persistent and prolonged eosinothila, with primarily hematologic, cardiac, neurologic and derrnatologic abnormalities. Cutaneous mmestations occur in 27-57% of patients. Two types of skin lesions have been noted: (1) erythrritous pruritic papules and nodules or (2) urticaria and angioedema. We report a case of hypereosinophilic syndrome with a vesicle eruption which is a rare skin lesion in tbis syndrome, in a 17 year old man. Diagnosis of hyprcsinophilic syndrome was established by clinical findings, rearked blood eosinophilia without a Brown cause, bone marrow aspiration and biopsy, liver scan and ultrasonography, and histopatholcgie findings of the skin.

A 41 year-old man had dark pigmented papules and plaques, 4 to 15 mm in size, on the proximal portion of the dorsum of the penile shaft and pubic area of 8 months duration. Over next several months, flesh colored, macerated papules, 2 to 4 mm in size, appeared on the left side of the scrotum Light microscopic examination from a pigmented lesion of the penile shaft showed typical findings of Bowen's disease. Ultrastructural findings included: widening of intercellular space, a decrease in the number of desmosomes with microvillous projections, aggregation of tonofilaments, an increase in the mitotic keratinocytes, an increase in the number of melanin granules, and disorganized bundles of tonofilaments surrounding chromosomes. Virus-like particles were not observed. Based on the ultrastructural findings and review of literatures, it seems to be probable that bowenoid papulosis is a clinical variant of Bowens disease.

Local or distant flap surgery has been applied in the soft tissue defect area where bone and tendon are exposed, but there are many pitfalls in these surgeries including limitation of donor site selection, as well as functional and aesthetic dissatisfaction of the donor and recipient site. So these problems have facilitated the development and study of skin substitute (artificial dermis). The history of artificial skin began in the 1980s with the invention of Stage I membrane by Yannas and Burke. Since then it has been developed and applied to chinical cases of extensive burn injury and soft tissue defect. In 1989, and artificial dermis (Terudermis) composed of fibrillar collagen and heat denaturated atelocollagen was developed by Konish. It has the advantage of allowing early-incorporation of cellular and vascular components into its collagen sponge, as well as dehydrothermal cross-linking, which is very weak. This study included 18 consecutive cases which underwent application of artificial dermis on bone and tendon from January 1997 to November 1998. The exposed areas were the result of trauma in 10 cases, postoperative complications in 2 cases, and other causes in 6 cases. The follow-up period ranged from 3 months to 18 months, averaging 11 months. A week after wound debridement and Terudermis application, neovascularization had begun and granulation tissue appeared aften 2-3 weeks. Then the split or full -thickness skin graft was secondarily applied resulting in the production of sufficient skin. In conclusion, Terudermis application to an area of exposed bone and tendon is a very useful method, especially when primary local or distant flap surgery cannot be used. This method is very simple, convenient and reliable.

The surgical construction of vagina could certainlty be done by skin grafting or flaps, but it involves hospitalization, discomfort,scarring of donor area and vaginal tract, hygiene problem. The tissues of the vagina are soft and distensible and it is reasonable to assume that these same tissues could be stretched, elongated or dilated with gradual external pressure. So, we performed the expansion of vaginal lining by self designed set of graduated dilators. The patients was a 27-years-old female whose chief complaint is amenorrhea and incapability to engage in sexual intercourse. On physical examination, this patients had a feminine figure with a normal vulva but only a vaginal dimple was observed. The patient was educated to carry out the mechanical dilation of this dimply by pressure 15 minutes twice a day. In the evening, with insertion of a dilator, the patient was asked to sit on a bicycle chair for 10 minutes. After 8 weeks, the overall outcome of vaginoplasty was successful. The vaginal tract was 8 cm in length and the largest vaginal speculum could be passed into vagina. The patient was able to engage in sexual intercourse without lubrication. The progressive dilatation of vaginal lining is non-invasive and probably the simplest way to treat the patients with congential vaginal atresia. So we recommend this method as the first treatment strategy before surgery.

Boric acid(H BO) is a weak topical anti infective agent. It can cause acute borism due to the internal absorption. Although the frequency is very rare, boric acid can also induce contact dermat.itis after topical spplication. We present allergic contact dermatitis to boric acid. The patch test results showed a positive reaction to 2% boric acid solution.

We reported a case of subcutaneous mass in a 22-year-old lady having unusual histopathologic findings mixed with both features of pilomatricoma and epidermal cyst and the meanings of these peculiar findings were discussed.

Male sexual function gradually decreases in parallel with aging. As the majority of diabetes mellitus develops later in life, mostly beyond the fifth decade, impotence in the diabetic patients can be ignored by physician as well as patients. Considerable evidence, however, indicates that diabetes mellitus does affect the male sexual function more significantly in diabetics than in non-diabetic is suspected. We studied 213 male diabetic patients and 233 non-diabetic male patients who were neither on medication nor have systemic diseases affecting sexual dysfunction. We analyzed the questionnaire regarding libido, erectile potency, intercourse frequency and partner's satisfaction, and we got several results as followings. In the diabetics, the prevalence of impotence was 20.4%, which was significantly higher than that(13.7%) of the control(p<0.01). Although the prevalence of impotence increases with aging in both groups, it was significantly higher in diabetic under the 7th decade and positively related to the disease duration. The erectile potency was also significantly lower in the diabetics. The scores of libido, intercourse frequency and partner's satisfaction were significantly lower in the diabetic compared with those in the control. The erectile potency was revealed to be higher in the patients whose blood glucose levels were controlled, compared with that of the patients with the uncontrolled levels. These results suggest that the prevalence of impotence is similar in Korean diabetic patients to those of the western countries, and the early treatment of diabetes mellitus is important for theprevention of impotence.
