횡문근육종은 영아에서 발생하는 가장 흔한 심장 내 양성종양으로 많은 수에서 그 크기가 감소하여 자연 소멸되는 것으로 알려져 있다. 하지만 일부 환자에서는 성장의 기능적 문제를 야기하여 수술적 치료를 필요로 하기도 한다. 환아는 산전 초음파에서 심실 내 다발성 종양이 발견되었으며 출생 직후부터 심한 좌심실 유출로 폐쇄로 인한 심장기능부전이 발생하였다. 생후 1일째 응급으로 수술을 시행하였으며 대동맥 절개를 통한 경판막 접근법으로 유출로를 막고 있는 종양의 일부분만을 절제하였다. 수술 후 시행한 초음파에서 유출로 폐쇄가 완전히 없어진 것을 확인할 수 있었으며, 3년간 정기적으로 경과 관찰한 결과 남아있는 종양은 그 크기가 점차 줄어드는 것을 확인할 수 있었다.

We report the case of a 68-year-old man with a stromal tumor of uncertain malignant potential (STUMP), which had metastasized to the lung. The patient complained of an enlarged mass in the anterior chest. Chest computed tomography (CT) showed a sternal abscess with multiple nodules in both lungs. A thoracoscopic lung biopsy of the nodules and incision/drainage of the sternal mass were performed simultaneously. CT of the pelvis revealed an enlarged prostate with irregular cystic lesions in the pelvis. Prostate biopsy was done and demonstrated hypercellular stroma with minimal cytological atypia, a distinct pattern of STUMP. The sternal abscess proved to be tuberculosis and the lung lesion was consistent with STUMP, which had spread from the prostate. However, to our knowledge, the tuberculous abscess might not be assoicated with STUMP in the lung. The patient refused surgical prostatectomy and was discharged with anti-tuberculosis medication. On one-year follow up, the patient had no evidence of disease progression.

폐에 발생하는 간엽 낭성 과오종(mesenchymal cystic hamartoma: MCH)은 매우 드문 종양으로 1986년에 처음으로 발표되었고 아직까지 유병율은 밝혀지지 않았다. 방사선 사진과 조직 검사에서 특징적으로 양측 폐에 다발성의 결절과 크기가 다양한 낭포들이 보인다. 결절들은 미성숙 간엽 세포들의 증식으로 이루어지고 결절의 크기가 점차 커지면서 낭포를 형성하게 되는데 낭포의 내경은 정상적 또는 화성 호흡 상피 세포로 이루어지고, 그 벽의 중간층은 방추형의 간엽세포충으로 되어 있다. 주증상은 객혈과 재발되는 기흉, 그리고 혈흉이다. 비교적 양성종으로 알려져 있지만 악성 변화의 가능성이 있다. 폐기포 절제술 시 폐 전체 표면에 다양한 크기의 낭포성 병소와 결절들이 육안적으로 관찰되었고, 조직 검사상 낭포의 내경은 호흡 상피로 둘러져 있었고, 그 벽의 중간층은 원시 간엽 세포층로 이뤄져있었다. 육안적 소견과 광학현미경하 소견이 간엽 낭성 과오종에 적합한 소견이었다.. 저자들은 자주 재발되는 기흉과 객혈이 있었던 27세의 여자에서 간엽 낭성 과오종을 경험하였기에 보고하는 바이다.

Objectives: Head and neck squamous cell carcinoma (HNSCC) is the most common head and neck malignant tumor. The molecular genetic changes involving both oncogenes and tumor suppressor genes are known to be involved in head and neck squamous cell carcinogenesis, but the roles of the known tumor suppressor genes in carcinogenesis are not fully elucidated. The objectives of this study are to demonstrate the genetic alterations including the loss of heterozygosity (LOH) , amplification, and microsatellite instability of known tumor suppressor genes in HNSCC and to evaluate the relationship between genetic alterations of tumor suppressor genes and clinicopathologic features. Materials and Methods: Genetic alterations of 10 micro satellite markers of the 6 known tumor suppressor genes (APC, EXT1, DPC4, p16, FHIT, and PTEN) were analysed by DNA-PCR in paraffin-embedded histologically confirmed HNSCC specimens. Results: The genetic alterations of tumor suppressor genes were found frequently. Among the genetic alterations, LOH was most frequently found one. LOH was found frequently in APC (45.4%), EXT1 (36.4%), DPC4 (54.5%), and p16 (50%), but not found in FHIT. Also, the author found that abnormalities of APC gene was related to cervical lymph node metastasis and recurrence and that abnormalities of EXT1 gene were coexisted with those of APC gene or DPC4 gene. But these coexistences had no correlation with clinical features. Conclusion: These results suggested that APC, EXT1, p16, and DPC4 genes might play important roles and multiple tumor suppressor genes may participate dependently or independently in the carcinogenesis of HNSCC. These results also suggested that APC gene might relate to prognosis.

Background: The aim of this study was to investigate Iranian cancer patient perceptions of their prognosis, factors that influence perceptions of prognosis and the effect this has on patient level of hope. Materials and Methods: Iranian cancer patients (n=200) completed self-report measures of their perceptions of their prognosis and level of hope, in order to assess the relationship between the two and identify factors predictive of perceptions by multiple linear regression analysis. Results: Cancer patients perceived of their prognosis positively (mean 11.4 out of 15), believed their disease to be curable, and reported high levels of hope (mean 40.4 out of 48.0). Multiple linear regression analyses demonstrated that participants who were younger, perceived they had greater family support, and had higher levels of hope reported more positive perceptions of their cancer prognosis. Conclusions: Positive perceptions of prognosis and its positive correlation with hope in Iranian cancer patients highlights the importance of cultural issues in the disclosure of cancer related information.

Bronchial carcinoid tumors are uncommon, constituting approximately 3-5% of all primary lung cancers. Classification of these tumors has evolved substantially as our understanding of the cellular, biologic, and clinical aspects of these neoplasms has improved. Initially, bronchial carcinoids were thought to be benign and therefore were classified as bronchial adenomas. Currently, however, they are well recognized as having the potential for both local invasion and distant metastatic involvement. Consequently, carcinoid tumors are frankly malignant. Thus bronchial adenoma is a misnomer that should no longer be used for bronchial carcinoids. Most investigators currently favor classifying carcinoid tumors as a type of neuroendocrine neoplasm because of their potential to secrete a variety of chemical substances found in both the central nervous system and the epithelial cells of numerous organs. Bronchial carcinoids are usually characterized by a slow growth pattern and a low incidence of metastasis, and histologically conformed by the azurophil staining and the presence of the characteristic neurosecretary granule on electron microscopy. Atypical carcinoid tumor was first defined by Arrigoni et al, who proposed the following criteria for separation of atypical carcinoid from typical carcinoid tumor : 1) increased mitotic activity with 1 mitotic figure per 1-2 high power fields(or 5-10 mitoses /10 HPF), 2) nuclear pleomorphism, hyperchromatism, and an abnormal nuclear-cytoplasmic ratio, 3) areas of increased cellularity with disorganization of the architecture, and 4) tumor necrosis. In contrast, typical carcinoid tumor may have focal cytologic pleomorphism, but necrosis is absent and mitotic figures are rare. Recently we experienced a case of atypical bronchial carcinoid with multiple distant metastasis, so we report this case with a review of the literature.

Pulmonary siderosis is a pneumoconiosis caused by chronic iron inhalation. A diagnosis of pulmonary siderosis is based on a patient history of iron inhalation, on chest radiographic findings, and on accumulation of iron oxide in macrophages within the lung. A typical radiographic finding of pulmonary siderosis includes ill-defined micronodules that are diffusely distributed in the lung. We experienced a 52-year-woman with a $1.3{\times}1.5$-cm mass in the left upper lobe with multiple nodules in both lungs. Because the radiographic findings were atypical, we conducted a video-assisted thorascopic lung biopsy procedure to exclude the diagnosis of metastatic lung cancer. After confirming iron deposition in the lung tissue and knowing the patient's occupational history of welding iron, we concluded that this was a case of pulmonary siderosis.

Chondroid synringoma (CS), pleomorphic adenoma of skin, is a benign tumor found in the head and neck region. CS was first reported in 1859 by Billorth for the salivary gland tumor. The usual presentation is an slowly growing, asymptomatic mass. A 53-year-old female with a history of chondroid synringoma had presented with multiple firm, nodular masses found in the left nostril area. The lesion had been excised 8 years prior and was diagnosed histopathologically, but had gradually recurred. Excision of the mass located in subcutaneous layer revealed four whitish, firm tumors surrounded with capsular tissue. Neither recurrence nor complications occurred during the 18 months follow-up period. In the head and neck region, chondroid syringoma should always be considered in differential diagnosis of soft tissue masses despite its rare incidence. For that reason, excisional biopsy with clear margin is the optimal diagnostic as well as therapeutic choice. We report a case of recurred chondroid syringoma on the nose in female patient.

Miliary brain metastasis from the lung is uncommon and has a poor therapeutic response. We report a case of pulmonary adenocarcinoma combined with multiple brain cystic lesions that were initially misdiagnosed as neurocysticercosis. A 53-year-old male who never smoked was admitted to our hospital with complaints of agitation and cognitive impairment. Brain magnetic resonance imaging showed innumerable, small nodular lesions with a central, low signal intensity in whole brain parenchyma. His symptoms were not improved by the empirical praziquantel medication for disseminated neurocysticercosis. After a transbronchial biopsy from the right middle lobe, we could diagnose the primary lung adenocarcinoma with a single nucleotide polymorphism in the epidermal growth factor receptor exon 20 at codon 787 (Q787Q). His neurologic symptoms and imaging findings have been gradually improving with a first-line Gefitinib treatment for five months. We recommend a more active diagnostic approach including biopsy in case of atypical imaging findings.
