Purpose: Tumors arising in the foot and ankle are uncommon and the malignant tumors are known to be rare compared with those of the other sites. We analyzed the clinical data of patients who have been diagnosed as having a tumor of the foot and ankle. Materials and Methods: From 1989 to 2006, we analyzed 185 patients who have been treated surgically and were pathologically confirmed of having tumors of the foot and ankle. Their clinical characteristics were reviewed retrospectively. Results: One hundred and fifty-seven cases were benign (84.9%) and 28 cases (15.1%) were malignant. 108 cases (58.4%) were benign soft tissue tumors and 49 cases (26.5%) were benign bone tumors. Malignant tumors included 17 cases (9.2%) of soft tissue tumors, 8 cases (4.3%) of primary bone tumors and 3 cases (1.6%) of metastatic bone tumors. The most common benign soft tissue tumor was ganglion (23 cases). Enchondroma (9 cases) was the most common among the benign bone tumors. Malignant peripheral nerve sheath tumor was the most common malignant tumor (4 cases). The predilection site for benign tumors was at the forefoot around toes while for the malignant tumor was around the ankle. 4.6% of benign soft tissue tumors and 8.2% of benign bone tumors had locally recurred and 14 cases (50%) of malignant tumor were confirmed as having distant metastasis. Conclusion: The ratio of malignant tumor and its metastasis rate was high. Therefore, the histopathologic confirmation is essential when treating tumors of the foot and ankle.

Background: Colorectal cancer (CRC) is a major cause of morbidity and mortality in the western world and also ranks as the fifth-leading malignancy and death in Thailand. This study aimed to provide a present outlook of colorectal diseases among Thai patients with special emphasis on CRC in Hatyai, Songkhla, southern Thailand. Materials and Methods: This retrospective study covered ten year data of CRC, benign colorectal tumors and non-colorectal tumors from the Department of Pathology in Hatyai Hospital, Songkhla, Thailand, between years 2003-2012. Incidence rates based on age, gender, ten year incidence trends, and distribution of histopathological characteristics of patients were calculated and demonstrated. Results: Out of 730 biopsies, 100 cases were benign colorectal tumors, 336 were CRC and 294 were non-colorectal tumors. Colorectal tumors (both benign and CRC) (60.1%) were more common than non-colorectal tumors (39.9%). CRC (77.1%) were more common than benign colorectal tumors (32.9%). Colorectal tumors were mainly found in patients aged over sixty whereas non-colorectal and benign colorectal tumors were found in those under sixty (P=0.01). sAmong CRC, adenocarcinoma contributed about 97.3% of all cases with well differentiated tumors being the most frequent (56.9%). Both benign colorectal tumors and CRC were more commonly found in males (63%) than females (37%). The incidence trend of CRC demonstrated increase from 2003-2012. Conclusions: The incidence of CRC increased in Hatyai from 2003-2012. CRC tends to be more common in people older than sixty, thus, screening programs, cost-effective analysis of treatment modalities, and treatment protocols for the elderly should be examined. Proper implementation of preventive measures such as changing lifestyle factors might enhance control of colorectal disease.

A retrospective study of 21 cases of chest wall tumors, 12 benign and 9 malignant, was carried out to review their clinical radiological and pathological features. On age distribution, most cases [80.9%] were found in 4th to 6th decades. The sex ration [M:F] was represented as 2.5:1. Of the 21 lesions, there were 8 cases of soft tissue tumors, 4 cases of bone and cartilage origined tumors and 9 malignant tumors which included 3 metastatic tumors. The overall mortality was 22.2% and all of the deaths were found in the malignant tumors. All of the patients with benign tumors were treated by excision without recurrence. Distinction between benign and malignant chest wall tumors was not possible using radiographic criteria unless cortical destruction and involvement of soft tissue were visualized. On the basis of our analysis, we believe that all tumors of chest wall should be considered malignant until proven otherwise and that wide excision should be carried out. This is necessary not only to obtain as adequate diagnosis but also to provide the best chance for cure in both benign and malignant lesions.

Breast ultrasonic reading is critical as a primary screening test for the early diagnosis of breast cancer. However, breast ultrasound examinations show significant differences in diagnosis based on the difference in image quality according to the ultrasonic equipment, experience, and proficiency of the examiner. Accordingly, studies are being actively conducted to analyze the texture characteristics of normal breast tissue, positive tumors, and malignant tumors using breast ultrasonography and to use them for computer-assisted diagnosis. In this study, breast ultrasonography was conducted to select 247 ultrasound images of 71 normal breast tissues, 87 fibroadenomas among benign tumors, and 89 malignant tumors. The selected images were calculated using a statistical method with 21 feature parameters extracted using the gray level co-occurrence matrix algorithm, and classified as normal breast tissue, benign tumor, and malignancy. In addition, we proposed five feature parameters that are available for computer-aided diagnosis of breast cancer classification. The average classification rate for normal breast tissue, benign tumors, and malignant tumors, using this feature parameter, was 82.8%.

Purpose: Tumors of the foot and ankle account for approximately 3%~5% of all musculoskeletal tumors, and accurate diagnosis is often delayed due to their rare prevalence. Therefore, the authors aimed to analyze the incidence, treatment methods, and prognostic factors of foot and ankle tumors treated at the authors' hospital. Materials and Methods: A retrospective single-center study examined 342 patients treated for foot and ankle tumors at the authors' hospital from January 2011 to February 2022. Data were collected from the electronic medical records (EMR) and picture archiving and communication systems (PACS). The information analyzed included gender, age, follow-up period, diagnosis, tumor occurrence and recurrence, treatment, and clinical outcomes. Results: Most cases (93.3%) were benign, but 6.7% were malignant. The main treatment for malignant tumors was surgical resection (91.3%). Approximately 53.1% of benign tumors and 91.3% of malignant tumors were treated with surgery, and two of the malignant tumors that did not undergo surgery had metastatic cancer. After surgery, 8.2% of benign lesions and 19.0% of malignant lesions recurred, and 9.5% of the patients with malignant tumors died after surgery. Conclusion: Most foot and ankle tumors are benign tumors, and the prognosis is not poor if treated properly, but most malignant tumors often require amputation. In some cases, however, amputation can be avoided with a combination of chemotherapy and radiation therapy.

The author reviewed 10 patients of chest wall tumors which were operated during 7 years, from 1970 to 1976, in Department of Thoracic and Cardiovascular Surgery in Chonnam University Hospital. Benign tumors were 6 patients, malignant tumors were 2 patients and metastatic tumors were 2 patients. Benign tumors were more than malignant tumors, but total cases were small, so, statistical analysis was not enough. Specific symptoms of chest wall tumor were swelling due to mass and pain. All cases had swelling due to mass and 4 cases [40%] had pain. Dyspnea was noted in metastatic tumors. The review of the literatures was also done.

Background: Diffusion-weighted magnetic resonance imaging (DWI) makes it possible to detect malignant tumors based on the diffusion of water molecules. It is uncertain whether DWI is more useful than positron emission tomography-computed tomography (PET-CT) for distinguishing benign from malignant mediastinal tumors and mass lesions. Materials and Methods: Sixteen malignant mediastinal tumors (thymomas 7, thymic cancers 3, malignant lymphomas 3, malignant germ cell tumors 2, and thymic carcinoid 1) and 12 benign mediastinal tumors or mass lesions were assessed in this study. DWI and PET-CT were performed before biopsy or surgery. Results: The apparent diffusion coefficient (ADC) value ($1.51{\pm}0.46{\times}10^{-3}mm^2/sec$) of malignant mediastinal tumors was significantly lower than that ($2.96{\pm}0.86{\times}10^{-3}mm^2/sec$) of benign mediastinal tumors and mass lesions (P<0.0001). Maximum standardized uptake value (SUVmax) ($11.30{\pm}11.22$) of malignant mediastinal tumors was significantly higher than that ($2.53{\pm}3.92$) of benign mediastinal tumors and mass lesions (P=0.0159). Using the optimal cutoff value (OCV) $2.21{\times}10^{-3}mm^2/sec$ for ADC and 2.93 for SUVmax, the sensitivity (100%) by DWI was not significantly higher than that (93.8%) by PET-CT for malignant mediastinal tumors. The specificity (83.3%) by DWI was not significantly higher than that (66.7%) for benign mediastinal tumors and mass lesions. The accuracy (92.9%) by DWI was not significantly higher than that (82.1%) by PET-CT for mediastinal tumors and mass lesions. Conclusions: There was no significant difference between diagnostic capability of DWI and that of PET-CT for distinguishing mediastinal tumors and mass lesions. DWI is useful in distinguishing benign from malignant mediastinal tumors and mass lesions.

Benign papillary tumors commonly arise in the upper respiratory tract but are rare in the lower respiratory tract, especially in the bronchi. Solitary benign papillary tumors arising at the bronchi,covered with stratified squamous epithelium and associated with little or no inflammatory cell response,seem to be rarest of all types of benign bronchial tumors. Only six cases of such tumors had been reported in the medical literature over the past 74 years until 1968. The following is a case report of solitary benign papilloma arising at the opening of the left main bronchus which was treated with bronchoscopic removal at Chest Surgery Depariment, N.M.C. on Sept.

Benign salivary gland tumors have relatively lower incidence, but it have various histopathologic diagnosis and biological behavior. Authors analyzed retrospectively 77 patients with benign salivary gland tumor who were treated surgically and had the following results. The most frequent age group was 5th decade, and sex distribution was not specific. The most common location was parotid gland(75.3%) and submandibular gland(20.8%) was next. Histopathologically, the most common salivary gland tumor was pleomorphic adenoma(82.7%) and Warthin's tumor(8.6%) was next. An asymptomatic mass was the most common presentation. Duration of symptoms and signs were mostly under the 5years(90.9%). Diameter of tumors was mostly under 4cm(76.7%). Parotid gland tumors were treated mostly with superficial parotidectomy and submandibular gland tumors were treated mostly with submandibular gland resection. The most common complication was facial nerve palsy(9 cases).
