A 13-year-old, female, Shih-tzu and a 10-year-old, female, Yorkshire terrier were presented with ulcerative keratitis caused by corneal endothelial degeneration. Generalized corneal edema, conjunctival hyperemia, focal corneal pigmentation, corneal neovascularization, sub-epithelial bullae, and positive fluorescein staining were observed during ophthalmic examinations. Thermokeratoplasty was performed on the overall edematous corneas. Healing of the cornea was completed within 25 days and corneal ulceration has not recurred after healing of the cornea in both cases. Other ocular complications were not observed except for a slight increase in corneal pigmentation. According to this study, thermokeratoplasty could be an effective treatment for corneal ulceration secondary to corneal endothelial diseases in dogs.

This study was performed to investigate the toxicity of DA-125 in beagle dogs, an anthracycline antitumor antibiotic. The dogs were administered DA-125 i.v. at 0.0023, 0.0375, 0.15 and 0.6 mg/kg/day, 6 days/week for 26 weeks. At 0.6 mg/kg, all male and female dogs were either sacrificed moribundly or dead during the 26-week treatment. The dogs revealed inactivity, salivation, dark bloody discharge, swelling of the subcutaneous injection site, abscess, and ulceration in the abdominal wall and legs. At 0.15 mg/kg, anorexia, salivation, and swelling of the injection site were observed. The food consumption was decreased with a statistical significance at 6 and 12 weeks treatment in males of 7.6 mg/kg. At 0.0375, 0.15 and 0.6 mg/kg, body weights were decreased significantly in a dose-related fashion after 17 weeks treatment. Total white blood cell counts for male dogs at 0.6 mg/kg were lower than those of control dogs after 13 weeks treatment, which appeared mainly due to decreased neutrophils. At 0.15 mg/kg, testicular atrophy was found in all males by gross pathology and the testicular weights were significantly decreased when compared to those of control males. Microscopically, the testis showed moderate atrophy of the seminiferous tubules and marked decrease in number of spermatozoa in the epididymal tubules. At 0.6 mg/kg, petechia or echymotic hemorrhage was observed in gastrointestinal tract, heart, lungs, and other organs at the necropsy, Marked atrophy of thymus were observed in both males and females. In addition, severe testicular atrophy was noted in all males. Microscopically, gastrointestinal tract showed hemorrhage, epithelial denudation, hypermucus secretion, and atrophy of intestinal villi. Seminiferous tubules of the atrophic testis were lined with Sertoli cells only and devoid of germ cells. Severe oligospermia or aspermia was present in the epididymal tubules. Bone marrow showed marked depletion of hemopoietic cells. In addition, marked atrophy was found in the lymphoid tissue of gastrointestinal tract, various Iymph nodes, and thymus. Injection sites showed marked inflammatory response with necrosis, necrotizing vasculitis, thrombus formation, and ulceration in the skin. According to the present results, no observed effect level appeared to be 0.0375 mg/kg. At 0.15 mg/kg, testis was a target organ, while at 0.6 mg/kg hemopoietic tissue, gastrointestinal tract, and testis were considered to be target organs. At 0.6 mg/kg the test compound seems to inflict a damage on the blood vessels causing hemorrhage in the various organs and tissues.

Pemphigus vulgaris is a rin, chronic intraepidermal bullous disease with potentially fatal outcome. Oral lesions precede skin lesions in at least $70\%$ of cases, and in cutaneous disease, concomitant oral lesions are encountered in $90\%$ of patients. This disorder involve the skin and mucous membranes, especially the oral and pharyngeal mucosa, but may also involve the nasal, oropharyngeal, laryngeal and esophageal mucosa. Oral lesions are initially vesicobullous but rapidly rupture, leaving a painful erosion that shows little tendency to heal. Pemphigus vulgaris affecting the oral mucosa is still diagnosed only after considerable delay, because oral ulceration in common, and clinicians believed the lesions to be caused by more common conditions such as recurrent aphthous stomatitis rather than a rare disorder such as pemphigus vulgaris. The definitive diagnosis of pemphigus vulgaris should be undertaken as early as possible, so that treatment can be started at an earl·y stage. Because of the presence of nonspecific oral ulcer, high degree of suspicion is often required to ultimately make the diagnosis of pemphigus vulgaris and then we report a case of pemphigus vulgaris with a literature review.

Mycosis fungoides is an uncommon, chronic fatal disease of lymphoreticular system associated with primary ski3 involvement for many years and terminating as a malignant lymphoma with involvement of lymph nodes and viscerae. On occasion it simulates numerous other nonspecific benign skin lesions, thus it may be impossible to decide whether the infiltrate represents early mycosis fungoides or nonspecific on the histopathologic ground alone. A case of mycosis fungoides was confirmed by electron microscopy and reported here. The patient was 69-years-old male who had suffered from erythematous scaly eruption on the whole body since 10 years. Skin biopsies of 4 times showed focal ulceration with chronic nonspecific inflammation and polymorphic cell infiltration in lower dermis, thus possibility of mycosis fungoides could not be completely ruled out. Electron microscopically several atypical lymphoid cells, which had a large cerebriform nucleus with peripheral condensation of dense chromatin and scant cytoplasm, were noted in the upper dermis. Intraepidermal infiltration of these atypical cells was also seen. It was thought that the electron microscopic study may be very helpful to differentiate equivocal mycosis fungoides from the nonspecific dermatosis.

Natural Killer/T-cell(NK/TC) lymphoma is a rare disease of oral and maxillofacial region with an aggressive clinical course, showed unusual clinical manifestations. Prognosis is generally poor and the disease is invariably fatal after systemic dissemination. A case of nasal NK/TC non-Hodgkin's lymphoma in the left maxilla that showed unusual clinical manifestations and a fulminant course of disease, are described with literature reviews. A 81-year-old female patient presented with rapidly growing ulceration and general malaise after extraction of right upper second premolar NK/TC lymphoma was subsequently detected by biopsy. rapid and wide invasion from maxilla to mandible developed within 10 days and multiple metastasis to whole body was after a few weeks. Although the time relationship is not clear, local invasion and multiple metastasis could be dissemination from localized disease of NK/TC. As seen in my case, the course can be excessively aggressive and fulminant even though it first appeared as a localized ulceractive lesion. She is expired 2 months after biopsy. Positivity of immunohistochemical stain (CD56, LCA, UCHL-1, CD3), which is a specific characteristic of NK/TC, may serve as a factor showing a poor prognosis of a malignant lymphoma

The detection of foreign bodies in the upper-aerodigestive tract is a fairly frequent event and can occur in various areas and for various reasons. In rare cases, foreign bodies can simulate a neoplasia. We evaluated similar cases during emergency regimen with an oral cavity mucosal lesion, causing lockjaw, sore throat, dysphagia, and swelling of the submandibular and laterocervical region. Physical examination revealed an extensive mucosal ulceration in the floor of the mouth and the lateral surface of the tongue, comparable to oral cancer. During a second, more accurate assessment, a partially deteriorated iron supplement tablet was found embedded in a mucosal pocket. After removing the tablet, gradual normalization of the tissue was observed without any sequelae. This is one of the many reasons why it is advisable and useful in cases of oral lesions to collect a detailed medical history and to perform an accurate clinical evaluation, including inspection and palpation of the lesion, before proceeding to further diagnostic assessments, especially in elderly patients taking many medications. However unlikely, it is possible that difficulty in swallowing pills or tablets could generate tumorlike lesions.

As an epidemiological survey, mortality of marbled rockfish, Sebastiscus tertius observed from a fish farm in Gyeongnam province of South Korea. The major macroscopic sign of the diseased fish was severe multifocal dermal ulceration. Histological observation revealed inflammation, necrosis and colonization of bacteria in various tissues (gill, liver, spleen and kidney). Bacteria was isolated from spleen and kidney in moribund and mortality fish. Seven bacterial isolates from the diseased fish were identified as Aeromonas salmonicida subsp. salmonicida using API 20E and 20NE, API 50CH API ZYM system. Under light microscopy, infected marbled rockfish showed the lifting of the lamella epidermal layer, edematous changes and hypertrophy of epithelial cell in the gill filament. The atrophy of the mucosal fold, erythema in the intestine, and the necrosis of hematopoietic tissue and renal tubule cells with karyolysis were observed in the kidney. In this study was demonstrated the histological reaction of red marbled rockfish infected by Aeromonas salmonicida. Furthermore, this is the first account of extensive dermatitis in Sebastiscus tertius due to atypical A. salmonicida infection, which has high potential in aquaculture among native fish species.

The Neurofibroma is a benign neoplasm originating from neural tissue such as Schwann cell, fibroblast and peripheral fibroblast, which rarely converts to malignancy. About 25-45% of neurofibroma are located in head and neck, and the most common sites are lateral cervical region and mouth. Because of its high vascularity and invasion to the adjacent organs, surgical resection may be confronted and limited, moreover large neurofibroma can cause large defect that needs various kinds of flap. The factors related to clinically suspected malignancy are painlessness, abrupt increase in size, firm fixation, and central ulceration, although the malignancy rate of neurofibroma is low. The complete resection was failed several times at local clinic, the patient was transferred to our hospital. We have successfully removed the retroauricular neurofibroma using transposition flap & free skin graft on its large defects.

Purpose: We reviewed the clinical finding of malignant melanoma of the foot in korean because it's advanced stage and extended lesion at diagnosis. Materials and Methods: Retrospective study was enforced about the 11 cases who has diagnosed to malignant melanoma of the foot from February 1995 to March 2004. The mean follow up period was 61 months. In this study we used age, sex, site, depth, histology, clinical stage, precursor lesion, misdiagnosis, interval to diagnosis, survival time, survival. Results: Average age was 58 years and number of female was six. Common site of involvement were heel of plantar surface (6 cases) and subungual area (2 cases). Depths of involvement were 0.3 to 10 mm, most common histological type was acral lentiginous melanoma (7 cases), stage 5 according to classification of Clark were 5 cases and stage 2 or more according to clinical staging were 8 cases. precursor lesion were benign melanocytic nevi (2 cases) and ill defined (9 cases). Chief complaint were increasing of size, color change, pain and ulceration. Conclusion: Malignant melanoma of the foot usually arise at nonvisible area and is easy to be misdiagnosed or delayed treatment. So it is hard to early diagnosis and have poor prognosis. So we need education and effort to early detection and diagnosis.
