Tooth related factors such as palatoradicular groove can be one of the causes for localized periodontal destruction. Such pathological process may result in apicomarginal defect along with inflammation of pulp. This creates challenging situation which clinician must be capable of performing advanced periodontal regenerative procedures for the successful management. This case report discusses clinical management of apicomarginal defect associated with extensive periradicular destruction in a maxillary lateral incisor, along with histopathologic aspect of the lesion.

A supeficial parotidectomy was performed under impression of benign or congenital lesion. Histopathologic diagnosis of intraductal papilloma was made on the surgical specimen. Authors report a intraductal papilloma arising from the parotid gland in childhood.

Primary cyst of the diaphragm is a rather uncommon disease. This is a report of a case of diaphragmatic cyst, located in the tendinous portion of the right diaphragm. The patient had no specific symptoms in the respiratory systems, but suffered from gastrointestinal symptoms [indigestion, epigastralgia, and loss of appetite etc.] for 2 months. Accidentally, on a simple chest x-ray examination, a round homogenous mass density was discovered. Tomography showed a well circumscribed parenchymatous mass. So a coin lesion in the medial segment of the right lower lobe was suspected. A thoracotomy was performed. There were no pathological findings in the lung and pleura. A ping-pong ball sized round mass, which was soft, elastic and fluctuated,was noted in the tendinous portion of the diaphragm. It was enucleated completely without diaphragmatic rupture, and diagnosed as a primary diaphragmatic cyst [fibrous-walled] by the histopathologic examination. Postoperative course was uneventful.

Lichenoid dysplasia is a lichenoid features with epithelial dysplasia clinically and histopathologically similar to oral lichen planus. It can be clinically mistaken for oral lichen planus, but has histopathologic features of dysplasia and a true malignant predisposition. The clinician should be able to differentiate between oral lichen planus and lichenoid dysplasia for the proper management. We experienced a 75-year-old man with erosive, erythematous lesion on the left buccal mucosa previously diagnosed as oral lichen planus. He underwent surgical excision and the final histopathological result confirmed it to be lichenoid dysplasia with massive candidal infection. We report this case with a review of the related literature.

Common radiographic appearances of ossifying fibroma (OF) are well demarcated margin, radiolucent or mixed lesion. Lesions for the radiographic differential diagnosis with OF include fibrous dysplasia, focal cemento-osseous dysplasia. Other confusing lesions might be the mixed lesions such as calcifying odontogenic cyst, adenomatoid odontogenic tumor, calcifying epithelial odontogenic tumor, and benign cementoblastoma. We reported three cases of OF in posterior mandible. These cases showed a little distinguished radiographic features of OF and diagnosed from a combination of clinical, radiographic, and histopathologic information. We need to further refine radiographic and histopathological features of OF and other confusing lesions with literatures review because some cases of these lesions are not easily differentiated radiographically and histopathologically.

Clear cell acanthoma (CCA) is an asymptomatic benign lesion of unknown origin that typically appears as a brownish, dome-shaped papule on the leg. It has an unusual clinical feature in that it appears as chronic eczema, Bowen disease, or Paget disease on the areola. Its histopathologic findings are well-demarcated psoriasiform acanthosis with pale keratinocytes (clear cells) that are rich in intracellular glycogen, which stain positively with Periodic acid-Shiff. We report herein on a young female patient with CCA on the areolar areas.

We report a case of 29-year-old man diagnosed as a primary eosinophilic granuloma (EG) lesion of the seventh cervical vertebra. He had paresthesia on both arms, and grasping weakness for 10 days. Cervical magnetic resonance image (MRI) showed an enhancing mass with ventral epidural bulging and cord compression on the seventh cervical vertebra. Additionally, we performed spine series MRI, bone scan and positive emission tomography for confirmation of other bone lesions. These studies showed no other pathological lesions. He underwent anterior cervical corpectomy of the seventh cervical vertebra and plate fixation with iliac bone graft. After surgical management, neurological symptoms were much improved. Histopathologic evaluation confirmed the diagnosis of EG. There was no evidence of tumor recurrence at 12 months postoperative cervical MRI follow-up. We reported symptomatic primary EG of cervical spine successfully treated with surgical resection.

We experienced 53 cases of tuberculous peripleural abscess, which had been proved by histopathological study, from Jan. 1980 to Dec. 1988. In 53 cases of abscesses, mean age was 25 years which was ranged from 1 year and 3 months old boy to 61 years old female [Male: Female=1.4: 1]. The location of the lesion was mainly right-sided [62%] and lateral predilection [53%]. In most of cases [85%], there was history of pulmonary tuberculosis and pleural thickening, but negative mycobacterial culture in the pus. Rib involved cases, confirmed by histopathologic examination, were 38.9% of all cases, which were all removed during operation. Combined pathologic lesions were all cleared at the same time, principally. There were 8 cases of recurred, of which at the same sided, 7 cases and contralateral sided, 1 case.

흉벽의 탄성섬유종은 피막을 형성하지 않는 양성질환으로 탄성섬유를 내포하는 섬유조직의 증식을 특징으로 하고 있으며, 나이 많은 여자의 견갑골 직하부에 가장 많이 발생한다. 비교적 천천히 자라며 악성으로 전환은 하지 않는 것으로 알려져 있다. 동통이나 통증, 운동장애와 같은 증상이 드물어 쉽게 지나치는 경우가 많다. 탄성섬유종의 진단은 특징적인 조직학적 소견으로 이루어지며 방사선학적인 검사로 예측이 가능하다. 48세의 여성에서 흉벽에 발생한 탄성섬유종을 경험하였기에 문헌고찰과 함께 보고하는 바이다.

A 39-year-old man presented to the department of emergency medicine in Seoul National University Hospital complaining of chest pain, heart palpitation, and headache. Upon arrival, a computed tomography scan showed a 7.0 cm×6.2 cm lesion with the typical features of a paraganglioma. The patient was treated with an alpha-blocker and a beta-blocker prior to surgical intervention. We removed the tumor successfully, and histopathologic findings indicated that the tumor was indeed a paraganglioma. Since intracardiac paraganglioma is a rare disease, we present this case together with a literature review.
