흉막에 발생한 고릴성 섬유종은 비교적 회귀한 질환으로 알려져 있으며, 대부분 장측 흉막에서 발생하고 벽측 홍막에서 발생되는 경우는 매우 드물다. 저자들은 48세 여자환자에서 우흉곽내 벽측 흉막에서 발생한 거대 고립성 섬유종 1례를 수술 치험하였다. 환자는 10개월전 부터 발생한 호흡곤란이 주증상이었고, 술전 흉부전산화 단층될영상 우측 폐실질을 주변으로 밀어내는 이종의 종괴형태를 보였다. 수술 소견상 종괴는 피낭에 싸여 있었고, 벽측 흉막에서 기 시하였다. 절제된 종괴의 크기는 20cmX15cmX11cm였고, 무게는 2200gm에 이르렀다. 환자는 합병증없이 퇴원하였으며 술후 6개월 간 추적 관찰하였으나 재발의 소견없이 양호한 상태를 보이고 있다.

Oncocytic neoplasm of the head and neck region accounts for approximately 1% of all salivary gland tumors, but only 5% of oncocytic neoplasm is malignant. Oncocytic carcinoma arising in the submandibular gland is exceedingly rare. We encountered a sixty seven-year-old male patient who presented with multiple mass in the right neck. Fine needle aspiration biopsy revealed a salivary gland tumor of predominantly oncocytic form, and a differential diagnosis included oncocytic adenoma or mucoepidermoid carcinoma. A right submandibular gland resection and modified radical neck dissection were performed. Histologically, the tumor cells showed nuclear pleomorphism, and stromal invasion, which were compatible with oncocytic carcinoma. After surgery, the entire neck region was irradiated. Seventeen months after the initial surgery, multiple metastases to the bone and lung were detected from the incidental pathologic bone fracture of the right humerus; palliative chemotherapy was performed to resolve this. We report a case of oncocytic carcinoma in the submandibular gland with a review of literature.

A 52-year-old man was referred to our clinic for an 11.3 mm nodule in the left lower lobe that was discovered on a chest computed tomography (CT) scan. Eleven small nodules were subsequently found in both lungs. Initially, we performed a transthoracic needle aspiration using CT scan guidance. The pathologic report showed a few clusters of atypical cells that were suspicious for malignancy. The positron emission tomography images revealed multiple lung nodules scattered throughout both lungs. The largest nodule (11.3 mm) in the left lower lobe did not have any discernible fludeoxyglucose uptake. For pathologic confirmation, we consulted a thoracic surgeon to perform the video-assisted thoracoscopic surgery. The final diagnosis was minute pulmonary meningothelial-like nodules (MPMNs). MPMNs are benign in nature, and only a few cases require treatment. However, when clinicians are suspicious of potential malignancy, a pathological correlation is essential, even if the final diagnosis is MPMNs.

Slowly growing lung cancers are quite rare and the leading cause of length time bias and over-diagnosis bias in lung cancer screening. We report 6 cases of slowly growing lung cancer in a tertiary hospital between January 1999 and December 2008. The clinical characteristics of these 6 cases with slowly growing lung cancer were examined. The median age at diagnosis was 68 years (range, 49~72), and 5 patients (83%) were female. The most common histology type was adenocarcinoma (83%). After excluding two patients who showed no change in the tumor size, the median tumor doubling time was 189 months (range, 86~387). The proportion of patients with slowly growing lung cancer appears to be particularly large in women, especially among patients with adenocarcinoma. Our experience shows that slowly growly lung cancers are more heterogeneous and diverse.

Background: Lung cancer is a fatal malignancy with high mortality and short survival time. The aim of this study was to estimate survival rates of Iranian patients with lung cancer and its associate predictive factors. Materials and Methods: The study was conducted on 355 patients admitted to hospitals of West Azerbaijan in the year 2007. The patients were followed up by phone calls until the end of June 2014. The survival rate was estimated using the Kaplan-Meier method and log-rank test for comparison. The Cox's proportional hazard model was used to investigate the effect of various variables on patient survival time, including age, sex, Eastern Cooperative Oncology Group (ECOG) performance, smoking status, tumor type, tumor stage, treatment, metastasis, and blood hemoglobin concentration. Results: Of the 355 patients under study, 240 died and 115 were censored. The mean and median survival time of patients was 13 and 4.8 months, respectively. According to the results of Kaplan-Meier method, 1, 2, and 3 years survival rates were 39%, 18%, and 0.07%, respectively. Based on Cox regression analysis, the risk of death was associated with ECOG group V (1.83, 95% CI: 1 Conclusions: The survival time of the patients with lung cancer is very short. While early diagnosis may improve the life expectancy effective treatment is not available.

Background: Upfront surgery followed by systemic treatment is recommended to treat clinical stage I-IIA small cell lung cancer (SCLC), but data on the clinical outcomes are sparse. Thus, this study evaluated the stage migration and long-term prognosis of surgically treated clinical stage I-IIA SCLC. Methods: We retrospectively reviewed 49 patients with clinical stage I-IIA SCLC who underwent upfront surgery between 2000 and 2020. Additionally, we re-evaluated the TNM (tumor-node-metastasis) staging according to the eighth edition of the American Joint Committee on Cancer staging system for lung cancer. Results: The clinical stages of SCLC were cIA in 75.5%, cIB in 18.4%, and cIIA in 6.1% of patients. A preoperative histologic diagnosis was made in 65.3% of patients. Lobectomy and systematic lymph node dissection were performed in 77.6% and 83.7% of patients, respectively. The pathological stages were pI in 67.3%, pII in 24.5%, pIII in 4.1%, and pIV in 4.1% of patients. The concordance rate between clinical and pathological stages was 44.9%, and the upstaging rate was 49.0%. The 5-year overall survival (OS) rate was 67.8%. No significant difference in OS was found between stages pI and pII. However, the OS for stages pIII/IV was significantly worse than for stages pI/II (p<0.001). Conclusion: In clinical stage I-IIA SCLC, approximately half of the patients were pathologically upstaged, and OS was favorable after upfront surgery, particularly in pI/II patients. The poor prognosis of pIII/IV patients indicates the necessity of intensive preoperative pathologic mediastinal staging.

In Nepal, while no population based cancer registry program exists to assess the incidence, prevalence, morbidity and mortality of cancer, at the national level a number of hospital based cancer registries are cooperating to provide relevant data. Seven major cancer diagnosis and treatment hospitals are involved, including the BP Koirala Memorial Cancer hospital, supported by WHO-Nepal since 2003. The present retrospective analysis of cancer patients of all age groups was conducted to assess the frequencies of different types of cancer presenting from January 1st to December 31st 2012. A total of 7,212 cancer cases were registered, the mean age of the patients being 51.9 years. The most prevalent age group in males was 60-64 yrs (13.6%), while in females it was 50-54 yrs (12.8%). The commonest forms of cancer in males were bronchus and lung (17.6%) followed by stomach (7.3%), larynx (5.2%) and non Hodgkins lymphoma (4.5%). In females, cervix uteri (19.1%) and breast (16.3%), were the top ranking cancer sites followed by bronchus and lung (10.2%), ovary (6.1%) and stomach (3.8%). The present data provide an update of the cancer burden in Nepal and highlight the relatively young age of breast and cervical cancer patients.

Primary malignant lymphoma of the lung is a very rare disease, which consists of 0.34% of entire malignant lymphoma. The majority are low-grade B-cell tumors, and because of their morphological peculiarities and overall excellent prognosis, many cases, like many other extranodal lymphomas, have been mislabelled as "pseudolymphomas" in the past. For these reasons their true incidence is difficult to estimate. An incidentally discovered mass in the right middle lobe of a 36-year-old woman was operated on November 9, 2001 at Hanyang University Hospital. A right upper lobectomy was done and the pathologic diagnosis of extranodal marginal zone B-cell lymphoma of MALT type was made.

A chest x-ray of 68 year old male showed pneumonic consolidation of right lower lung field with blunting of right cardiac border. Computerized tomography of chest revealed infiltrative mass with V-shaped calcification just below right main bronchus. This finding has to be made into differential diagnosis of numerous pulmonary diseases including, mycobacterial disease, neoplasm, lymphadenopathies, and foreign bodies. Initial bronchoscopic findings suggest endobronchial mass lesion on right intermediate bronchus but endobronchial biopsy fail to prove malignant cell or underlying illness. But repeated endobronchial biopsy shows metallic material in the right Intermediate bronchus and we remove it with alligator jaws forcep under bronchoscopy. He was well after discharge.
