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.

Lipomatosis is a condition containing multiple lipomatous masses.Lipoma is a benign neoplasm composed of adult adipose tissue, and occur most often in the fifth or sixth decade and rarely in the pleura. Pleural lipomas are usually asymptomatic and revealed as an incidental roentgenographic findings. The patient was 59 year-old male and admitted because of dyspnea-on-exertion for 30 years. Chest CT revealed right pleural mass abutting on the chest wall, measuring minus 80 hounsfield units. The mass was resected with calcified pleural plaque and confirmed to be lipomatosis with collagenous fibrosis arising from viserai pleura.

Basal cell carcinoma is a malignant epithelial neoplasm of the skin and the most common human skin cancer. It is generally associated with a good prognosis. In this case report, a giant basal cell carcinoma of the nodulo-ulcerative type showing wide ulceration with marginal multiple small nodules, is presented. It was trapezoidal in shape, having dimensions of 7 cm at the greatest basal width, 6 cm vertically with different anterior and posterior margin dimensions, and 5 cm horizontally at the top margin. After wide excision of the lesion including 5-10 mm safety margins, the wound was reconstructed with a local skin flap and split-thickness skin graft. The reconstructed wound healed well without recurrence for 1 year.

Tumor of follicular infundibulum (TFI) is a rare benign cutaneous appendage tumor that does not have characteristic clinical features. It is mainly present in the head, neck, and trunk as a solitary lesion. In particular, TFI typically manifests as a plate-like proliferation with multiple thin epidermal connections comprise of monomorphic cells. TFI do not represent cutaneous characteristics, but have clinical significance because TFI is associated with basal cell carcinoma and Cowden's syndrome. We report a case of TFI in parietal scalp with a review of literatures.

지방종은 성숙한 지방세포로 이루어진 흔한 연조직 양성 종양이다. 그러나, 구강에서는 드물게 발생하며, 일반적으로 단독으로 발생하기 때문에 구강내에서 다발성으로 발생한 지방종을 경험하기는 매우 어렵다. 이에 저자는 아주 드물게 발생하는 혀의 다발성 지방종을 경험하여서 이를 보고하며 구강 지방종에 대해 고찰하고자 한다.

H$\"{u}$rthle cell neoplasm of the thyroid gland is an uncommon, but potentially malignant lesion. However, in many instances, the malignant potential of the H$\"{u}$rthle cell neoplasm is very difficult to judge histologically. For this reason, the biologic behavior of this tumor and its optimal treatment have come under considerable debate in recent years. In order to review the clinicopathologic features of the H$\"{u}$rthle cell neoplasm and to determine its optimal treatment modalities, we studied 26 patients with path logical proof of H$\"{u}$rthle cell tumor from January 1987 to September 1997. We also performed an immunohistochemical study using the monoclonal antibodies against antigen CD34 for the angiogenic activity of this tumor and evaluated the differences of microvessel density(MVD) between benign and malignant tumors. The age of the patients ranged from 1 to 71 years with a mean of 44.2 years. There were 6 males and 20 females(M : F= 1 : 3.3). The accuracies of fine needle aspiration biopsy and frozen section were very low; 6.3% and 34.8%, respectively. There were 20 benign tumors and 6 malignant tumors(23.1%). All the malignant tumors were microinvasive(intermediate) type which had minimal capsular invasion and most of them(5 cases) were diagnosed postoperatively. Any specific clinicopathologic differences were not seen between benign and intermediate groups. Most of the cases had conservative surgeries(15 ipsilateral lobectomy-isthmusectomy, 7 subtotal thyroidectomy) while total thyroidectomy was performed in 4 cases. Of the cases with malignant tumor, 2 had ipsilateral lobectomy-isthmusectomy, 3 had subtotal thyroidectomy and the remaining 1 had total thyroidectomy. Mean size of the tumors was 3.0 cm(0.1- 8.5 cm) in the greatest diameter and multiple tumors were seen in 6 cases(23.1 %). During the follow-up period, only one recurrence(3.8%) of benign tumor occurred but distant metastasis or cause-specific death was seen in the benign or intermediate groups. Mean MVDs of the benign(n=13) and intermediate(n=6) groups were $121.7{\pm}35.3$ and $114.3{\pm}31.7$, respectively and there was no statistical significance between them. In conclusion, because of the low accuracies of fine needle aspiration biopsy and frozen section for the H$\"{u}$rthle cell neoplasm, the extent of surgery could be individualized based on permanent pathologic examination; Conservative surgery would be adequate for patients with benign or intermediate H$\"{u}$rthle cell neoplasm and total or near-total thyroidectomy for those with definite malignancy.

Low-grade endometrial stromal sarcoma (ESS) is an uncommon gynecologic malignancy of mesodermal origin. Pulmonary metastasis of low-grade ESS can occur years and decades after the treatment of the primary disease. Low-grade ESS is frequently mistaken as benign uterine neoplasm like uterine leiomyoma, which can potentially lead to a misdiagnosis. We present a case of a 42-year-old woman with low-grade ESS, that initially presented as an incidental lung mass with multiple pulmonary nodules, seven years after an uterine myomectomy. A $6.9{\times}5.8cm-sized$ intrapelvic mass suspected of uterine origin was discovered while searching for potential extrathoracic primary origin. A pelviscopy and simultaneous thoracoscopic lung biopsy were conducted for pathologic diagnosis. Finally, the diagnosis was confirmed as low-grade ESS with lung metastasis based on the histopathologic examination with immunohistochemical stain, which was showed positive for CD10 and hormone receptor markers (estrogen and progesterone receptors) in both pelvic and lung specimens.

유방을 침범하는 혈액종양은 굉장히 드물게 보고되었다. 우리는 유방의 다발성 결절로써 재발한 급성 골수성 백혈병의 증례를 보고하고자 한다. 77세 여자 환자가 양측 유방의 촉지되는 다발성 결절로 외래를 내원하였다. 환자는 급성 골수성 백혈병(acute myeloid leukemia; 이하 AML)으로 진단받고 9차례의 항암치료 이후 완전 관해가 된 병력이 있었다. 유방 촬영과 유방 초음파에서 환자의 촉지성 병변이 영상의학적으로 확인되었으며 액와부 림프절 종대도 동반되었다. 총생검으로 얻은 검체는 면역화학염색을 통해 AML과 blastic plasmacytoid dendritic cell neoplasm의 형태를 보였으며 추후 진행한 골수 생검에서 AML로 확인되었다. 이렇듯 굉장히 드물지만, 혈액암의 병력을 가진 환자가 유방의 촉지성 종괴로 내원하였다면 담당의는 적절한 조직검사 및 면역화학검사로 정확한 진단을 하여 환자가 적절한 치료를 받도록 해야 한다.

Multiple myeloma is malignant neoplasm of plasma cells. Mandible lesions are rarely the first symptoms of multiple myeloma. While sensory dysfunction and pain are the main symptoms of traumatic trigeminal neuropathy, the same oral symptoms can appear in cases of multiple myeloma with developed mandible lesions. In addition, if the radiological osteoporosis or lytic lesion is seen in older patients, further examination is required to find the cause of the symptoms. In this paper, we present a case that was tentatively diagnosed as traumatic trigeminal neuropathy after left third molar extraction, but later confirmed as multiple myeloma.
