This case was diagnosed as multiple cementoosseous dysplasia on the basis of clinical & radiological features but was diagnosed as ossifying fibroma on the basis of histopathological feature. The histopathologic features of the multiple cementoosseous dysplasia and cementoossifying fibroma have common features of cementum, fibrous network and bone. Multiple cementoosseous dysplasia is reactive lesion and shows restricted lesion size, occurred on anterior and posterior tooth of the mandible and needs no treatement except periodic follow up. But Cementoossifying fibroma is the true neoplasm and grows continuously and needs surgical removal. The final diagnosis of the multiple cementoosseous dysplasia requires good correlation of the clinical, histopathological, and radiological features.

In 2007 to 2008, a fruit rot of Melon (Cucumis melo L.) caused by Sclerotium rolfsii occurred sporadically in a farmer's vinyl house in Jinju City. The symptoms started with watersoaking lesion and progressed into the rotting of the surface of fruit. White mycelial mats appeared on the lesion at the surface of the fruit and a number of sclerotia formed on the fruit near the soil line. The sclerotia were globoid in shape, 1${\sim}$3 mm in size, and white to brown in color. The hyphal width was measured 3 to 8 ${\mn}$. The optimum temperature for mycelial growth and sclerotia formation was 30 on PDA. Typical clamp connections were observed in hyphae of grown for 4 days on PDA. On the basis of symptoms, mycological characteristics and pathogenicity to the host plant, this fungus was identified as Sclerotium rolfsii Saccardo. This is the first report of the fruit rot of Melon caused by S. rolfsii in Korea.

Cutaneous horn is a morphologic designation for a projectile, conical, dense hyperkeratotic nodule that resembles the horn of an animal. The lesion varies in size from only a few millimeters to several centimeters, in color(white or yellowish) and in form (straight, curved, or twisted). It arises from a wide range of epidermal lesions, which include benign lesions, premalignant lesions and malignant lesions. An 83-year-old women came to our clinic with a giant cutaneous horn on the right chin and a small horn on the left upper eyelid. The patient had no palpable cervical lymph node. A wide elliptical skin incision was made and the horn was totally excised. In pathology, the giant cutaneous horn on the right chin revealed a moderately differentiated squamous cell carcinoma with subcutis invasion at its base. "Giant cutaneous horns" have often been associated with invasive squamous cell carcinoma. Cutaneous horns are common lesions usually found on the face, rarely larger than 2 cm. As large cutaneous horns are often associated with underlying malignancy, histopathologic examination of the base of the lesion is necessary to rule out carcinoma and full excision is recommended.

Xanthelasma palpebrarum is the most common cutaneous xanthoma found on the medial side of the eyelid. The typical lesion is usually a flat and yellowish plaque on the skin. However, we report on a unique case of intramuscular xanthoma found during blepharoplasty for the correction of ptosis. A 53-year-old male patient visited our department with a complaint of a ptotic eyelid. He was concerned about the cosmetic appearance and the uncomfortable feeling while opening his eyes, and wanted these problems to be solved. A yellowish plaque of about $0.3{\times}0.3cm$ in size was found in the orbicularis oculi muscle during the surgery. The lesion was excised and xanthelasma was confirmed with biopsy. We have found this specific case of xanthelasma palpebrarum in the only muscle. Therefore, a careful approach to clinical and histologic examination and imaging is required for patients with these lesions.

Congenital intratympanic membrane cholesteatoma (ITMC) is a rare type of congenital cholesteatoma located within the tympanic membrane. This lesion tends to increase in size over time. The development of ITMC can cause several complications such as hearing impairment, dizziness, facial palsy, and intracranial complications, similar to any other cholesteatoma. The treatment of congenital cholesteatoma requires the removal of the lesion through surgery, because disease progression induces bony destruction of the nearby tissue. Most patients presenting with this cholesteatoma type are also treated with primary surgical removal. However, we recently experienced a case of an ITMC that showed a natural transition to an external auditory canal cholesteatoma.

Psoriasis is a common chronic inflammatory skin disease that is histopathologically characterized by abnormal differentiation and hyperproliferation of keratinocytes, infiltration of T lymphocytes, and alternations of the dermal vasculature. Pulsed dye laser (PDL) is commonly used to treat cutaneous vascular lesions, and it has been studied for the treatment of localized psoriatic lesions. A 30-year-old female patient with refractory psoriasis on her forehead was treated using PDL. After two sessions, the size of the psoriatic lesion increased, which might have occurred due to koebnerization. As the patient continued to receive PDL treatment, the lesion showed significant improvement with no recurrence on the one-year follow-up. We present here a case of refractory psoriasis treated with PDL and demonstrates an association between a delayed therapeutic effect and the Koebner phenomenon.

Objectives : The water extract of Sopung-tang (SPT) has been traditionally used in the treatment of acute stroke in Oriental Medicine. Pro-inflammatory cytokines play a critical role in the onset of post-ischemic inflammatory cascades. The present study was designed to investigate the effects of SPT on pro-inflammatory cytokine production in a photothrombotic ischemia mouse model. Methods : After SPT oral administration to the mice for five days, with using Rose Bengal and cold light, photothrombotic ischemia lesion was induced in stereotactically held male BALB/c mice. Also, results including, gross finding lesion size, histopathological finding changes, and inflammatory cytokine expression changes from the photothrombotic ischemia mouse model were observed. Results : The photothrombotic ischemia lesion was decreased by the oral injection of SPT. Also, SPT inhibited the expression of TNF-$\alpha$, IL-$1{\beta}$, IL-6, the active form of caspase-3 protease, and transglutaminase-2 in the photothrombotic ischemia lesion. Conclusions : These results suggest that SPT protects the ischemic death of brain cells through suppression of the production of anti-inflammatory cytokines and catalytic activation of caspase-3 protease in the photothrombotic ischemia mouse model.

A cyst is a pathologic lesion characterized by a cavity filled with fluid, celluar products, air, or a combination of these. Dentigerous cysts were formed around the crown of unerupted teeth. The reduced enamel epithelium persists around the crown after it has formed. Proliferation of the epithelium in a fluid-filled sac may be induced by osmotic pressure. In the first decade the most frequent location is the premolar site. In each subsequent decade the largest number of cysts are in the mandibular third molar site, with the second most frequent site being the maxillary canine. The treatment of odontogenic cyst can be mostly classified into three types of cyst enucleation, marsupialization and decompression. We should consider age of patient, anatomic structure, location and size for choosing a treatment method. Advantage of cyst enucleation is fast healing, but a injury of a surrounding structure is highly. Marsupialization is conservative treatment that can reduce the damage of a adjacent structure, but it is only limited at superficial lesion. Decompression also is conservative treatment, but it has the difficulty of the oral hygiene and the troublesome of the lavage. We present the possibility that reduces the defect of decompression and cures the lesion efficiently. We report a male patient with the dentigerous cyst developed at left mandibular third molar in this study. We used the decompression for a treatment and created special appliance to treat the lesion efficiently. We report a case of the cyst treatment that is association with efficiency of decompression appliance.

A giant cell granuloma and a cementifying fibroma occurring in the same lesion of right mandibular body in a 10 year old boy is presented with a 12 month follow up without recurrence or any other complications after operation. The relatively small lesion of cementifying fibroma was well delineated from the larger lesion of central giant cell granuloma, and as their origins are different each other(odontogenic or connective tissue origin), we have considered that both lesions had developed independently. Clinically, the evidencesa of aggressiveness of giant cell granuloma were also found, that is, large size, earlier age of 10, root resorption of lower right 1st annd 2nd molars and cortical perforation. With curettage and electric cauterization, we have treated both lesions satisfactorily.

A growing number of people are enjoying sports activity with a rise in national income. In this current, many patients complain of traumatic shoulder dislocation and chronic instability with bony Bankart lesion. Computed tomography arthrography is good diagnostic modality for bony Bankart lesion. It is important to consider the patients' factors such as occupation, sports activity, size of preoperative glenoid bone loss before decision of treatment. As development of arthroscopic treatment, there is no significant difference in the result of bony Bankart repair between arthroscopic surgery and open surgery. However, open surgery should be considered for patients with preoperative glenoid bone loss more than 25% or in need of collision sports activity.
