  • This study was performed to elucidate the histopathologic distribution of immunoglobulins, particularly IgA, IgG and IgM in the periapical lesions, including 22 periapical granulomas and 18 periapical cysts. The immunoperoxidase staining method using reagents manufactured and supplied by Danish DAKO company was employed in this study. In comparison with the immunohistochemical methods, this method was proved to be reliable and convinient one to detect immunoglobulins in the tissue. The following results were obtained: 1. In the 22 periapical granulomas, IgG was found in 20 cases (90.9%), IgA in 16 cases (72.7%) and IgM in 19 cases (86.3%). 2. In the 18 periapical cysts, IgG was found in 16 cases (88.8%), IgA in 13 cases (72.2%) and IgM in 15 cases (83.3%). 3. The distribution of immunoglobulins both in periapical granulomas and periapical cysts was in great diversity according to the lesion and area. 4. More immunoglobulins were found in the exudative area with moderate or severe infiltrations of plasma cells and lymphocytes and less concentration of immunoglobulins were seen in the area with leukocytes infiltration and tissue destruction. 5. The area with collagenolysis and reparative activity contained more abundant IgG and IgM than IgA in periapical granulomas. 6. IgG was dominant in the granulomatous connective tissue and immunoglobulins were not easily found in the fibrous capsule in periapical cysts.

  • Chronic eosinophilic pneumonia is a very rare disorder of unknown etiology characterized by striking systemic and pulmonary manifestations such as fever, weight loss, dyspnea, blood eosinophilia, and fluffy peripheral opacities on chest radiograph. A number of these patients developed asthma before or with the onset of illness. The roentgenographic lesion rapidly resoluted with corticosteroid and recurrence was occasionally occured in the same location. Histopathologic features of chronic eosinophilic pneumonia include dense aggregates of eosinophils, histiocytes, and multinucleated giant cells within alveolar spaces, interstitium, and bronchioles associated with scattered lymphocytes and plasma cells. We report a case of chronic eosinophilic pneumonia diagnosed by clinical, radiographic, and histologic findings with review of the literature.

  • An 8-year-old, female Pointer dog was presented with weight loss, hematochezia, and dyschezia. For the diagnosis, physical examination, complete blood counts, serum chemistry, radiography, ultrasonography, computed tomography, colonoscopy, cytology and histopathological examination were performed. The complete blood counts and serum biochemistry results were within the reference range. Ultrasonographic findings were presented with the thickened wall of the colon and rectum. Colonoscopy revealed irregular and ulcerated mucosal surface, mass and luminal narrowing of colorectal lesions. There were thickened wall and contrast enhancement of the lesion in colorectal region on the computed tomography. The cytologic examination suggested the adenocarcinoma. Postmortem histopathologic examination revealed adenocarcinoma. Based on these findings, the dog was diagnosed with annular colorectal adenocarcinoma.

  • Inflammatory pseudotumor was originally described in the lung, but recently has been recognized to occur in various sites. A 56-year-old female was referred to our department with a painless swelling of the right midfacial area since 3 months ago. Clinical examination showed non-specific intraoral findings, but asymmetric facial appearance and numbness of the right midfacial area. Plain radiographs and CT images showed aggressive destruction and irregular thickening of the right maxillary sinus wall, increased antral opacification, and destruction of the zygomatic arch. A relatively well-defined soft tissue mass occupied the right maxillary sinus, nasal cavity, zygoma, and infraorbital region. The soft tissue mass showed mild enhancement on CT. Radiographically, this lesion presented a rapidly enlarging mass demonstrating aggressive behavior, mimicking a malignant tumor. Histopathologic examinations showed plasma cells and inflammatory cells in variable fibrotic tissues and demonstrated positive reactivity for vimentin. No malignent changes could be found.

  • Sentinel lymphnode biopsy is widely performed in the management of malignant melanoma and breast cancer. The sentinel lymphnode is the prime site of draining from the malignant lesion and of metastasis. The aim of this study was to evaluate a usefulness of lymphoscintigraphy in conjunction with a removal of sentinel lymphnodes of skin and soft tissue malignancy. We studied 11 patients selected between January, 2003 and November, 2004. Clinically sentinel lymphnodes free of metastasis were examined with lymphoscintigraphy, gamma detection probe and vital dye staining, and we reviewed histopathologic findings and inert status of the nodes and the results fo treatment. Nine cases were malignant melanoma, one was squamous cell carcinoma on the left hand and another one leiomyosarcoma. Sentinel lymphnodes were identified in all cases. Three cases of malignant melanoma had positive sentinel lymphnodes on histological examination. All patients with positive sentinel lymphnodes were treated with therapeutic regional lymphadectomy, chemotherapy and adjuvant regimen. Four patients underwent PET scanning and followed sentinel lymphnode biopsy. Two had no metastasis signs on PET scanning. Therapeutic lymphnode dissection was carried out upon the patients whose sentinel lymphnode was positive on PET scanning. We contend that lymphoscintigraphy and sentinel lymphnode biopsy are reliable to confirm regional lymphnode metastasis of the skin and soft tissue malignancy, and blind extensive lymphnode dissection can be spared.

  • Purpose: Basosquamous carcinoma is a rare malignancy, with features of both basal cell carcinoma and squamous cell carcinoma. It is considered as aggressive tumor with a high risk of recurrence and metastases. Authors report a case of basosquamous cell carcinoma. Methods: A 72 year-old man, who had an erythematous ulcer on his left auricle, described a slow growing lesion, starting at the posterior surface of the superior helix with a steady increase in size during the past 10 years. At operation, auricular cartilage was grossly invaded by the tumor and was, therefore, amputated with tumor-free margins. Results: Histopathologic examination was revealed a basosquamous cell carcinoma. On positron emission tomography/computed tomography (PET/CT) and neck CT were negative for signs of further nodal involvement or metastases to other organs. At follow-up 6 months later, his wounds were noted to be well healed, with no evidence of local recurrence or identifiable metastases. Conclusion: Because basosquamous cell carcinoma has a significant potential to recur and metastasize, surgical excision for this type of carcinoma should be more extensive than that performed for conventional basal cell carcinoma or squamous cell carcinoma. In addition, regional lymph nodes should be monitored and close follow-up should be carried out.

  • Alimentary lymphoma accounts for approximately 5% of neoplasm and diffuse lesion is more common than solitary nodular form in dogs. An eleven year-old male Yorkshire terrier was examined because of nonspecific gastrointestinal symptoms such as anorexia and vomiting for 10 days. An abdominal mass was palpated, which was originated from small intestinal wall in abdominal ultrasonography. Small intestine was obstructed by hypoechoic mass and lost normal layering and measured 24.5m. After fine-needle aspiration, septic peritonitis due to intestinal rupture occurred and emergency surgery was performed. Solitary mass was found in small intestine and diagnosed as alimentary lymphoma through histopathologic examination. Conclusively, abdominal ultrasonouaphy could verify the thickened bowel, loss of wall layering and decrease of motility and percutaneous ultrasound-guided fine-needle aspiration is considered as useful diagnostic technique, especially in nodular form of alimentary lymphoma.

  • Childhood intestinal tuberculosis is difficult to diagnose for its protean clinical manifestations, especially in cases without pulmonary involvement. Differential diagnosis with Crohn's disease, inflammatory bowel disease and other malignancy is also important. Surgery has often been required for pathologic confirmation or therapy. Colonoscopy may be performed safely under consciousness sedation in children for bacteriologic and histopathologic confirmation of the biopsy specimen in addition to gross appearance of the lesion. We have experienced a case of intestinal tuberculosis presenting with chronic abdominal pain, diarrhea, weight loss and anemia in a 9 year old girl who was diagnosed by a colonoscopic examination and culture of the biopsy specimen from the ascending colon. The patient was managed with antituberculous drugs and recovered uneventfully.

  • A case of sporotrichosis misdiagnosed as lupus vulgaris was presented. A 56-year-old woman had bean to pea sized, nontender pustules and a hypertrophic-sear-like nodule on the right thigh. She denied any trauma before the lesions developed. Histopathologic findings from the lesion showed tuberculosis-like granulomatous changes. And she was diagnosed as lupus vuagaris. She also had pulmonary tuberculosis and had been treated with antituberculous drugs for 1 year. But skin lesions was not cleared. We suspected the lesions as one of deep mycoses and could confirm sporotrichosis by mycologic studies. They showed characteristic gross colonies and microscopic findings of Sporothrix schenckii.

  • Bordetella bronchiseptica and Pasteurella multocida are two main pathogens responsible for atrophic rhinitis (AR), which causes considerable economic losses in swine industry worldwide. Commercial vaccine has been widely used to prevent the damage from AR in Korea. Adverse effects of vaccination at the injection site have been reported, which results in the numerous complaint from farms. However, data on about local reaction at the injection site remains limited. In this study, we compared the local adverse effects of three commercial vaccines following intramuscular injection. The results showed that no gross lesion was founded at the injection sites of all three vaccines. In histopathologic examination, a various level of lesions was identified. Especially, the local reaction of vaccine including saponin as an adjuvant showed the lowest level of histopathological lesions, when compared to those of oil-based and vitamin E-based vaccines. Therefore, this study would provide the information about the extent of local reaction at the injection site and help the farmer to select AR vaccine in order to avoid adverse reaction due to vaccination.
