Low-grade fibromyxoid sarcoma (LGFMS) is a rare soft tissue tumor. There have been only a few prior fine-needle aspiration (FNA) cytological reports. Recognition of this tumor is important because of its potential for metastasis despite its indolent nature and its deceptively bland cytologic appearance. A 60-year-old male presented with a slowly growing mass in the left calf detected 10 years ago. The patient underwent surgical excision. FNA cytology was performed directly on the mass. The smears showed low cellularity composed of hypercellular tissue fragments, hypocellular loose aggregates, and stripped nuclei. The cytoplasm was seen as either collagenous material or very thin fibrillary collagen strands. Tumor cells had spindle, ovoid, or irregular nuclei, fine chromatin, and small nucleoli. Focally slight degree of nuclear pleomorphism is noted. There were no mitotic figures. Blood vessels were frequently seen. Immunocytochemically, tumor cells were negative for S-100 protein, desmin, smooth muscle actin, and CD34. The diagnosis of LGFMS is rarely possible by cytology alone; however, LGFMS should be included in the differential diagnosis of spindle-cell tumors consisting of hypercellular and hypocellular components with some capillary-sized vessels arising in the deep soft tissue of the lower extremities, particularly the thigh. The immunocytochemical findings are of help in the differential diagnosis.

Context: Patients diagnosed with a cancer have a life time risk of developing another de novo malignancy depending on various inherited, environmental and iatrogenic risk factors. Of late the detection of new primary has increased mainly due to refinement in both diagnostic and treatment modalities. Cancer victims are surviving longer and thus are more likely to develop a new metachronous malignancy. Aims: To report our observed trend of increase in prevalence of both synchronous and metachronous second malignant neoplasms among cancer victims and to review the relevant literature. Settings and Design: A hospital based retrospective collection of prospective data of patients diagnosed with second denovo malignancy. Materials and Method: The study was conducted over a 5 year period from July 2008 to June 2012. All patients diagnosed with a histologically proven second malignancy as per Warren Gate's criteria were included. Various details regarding sex, age at presentation, synchronous or metachronous, treatment and outcome were recorded. Conclusions: The occurrence of multiple primary malignancies is not rare. Awareness of the possibility alerts the clinician in evaluation of patients with a known malignancy presenting with unusual sites of metastasis. Individualizing the treatment according to the stages of the primaries will result in durable cancer control particularly in synchronous double malignancy.

Synovial sarcoma us a rare malignant neoplasm of the soft tissue arising in the lower extremity, inguinal area, and upper arm. The majority occurs in patients between the age of 15 and 40 years. The histologic diagnosis is based on the classical biphasic type with the distinct epithelial and spindle cell components. We have recently encountered a case of metastatic synovial sarcoma of the lung diagnosed by fine needle aspiration cytology. A 34-year-old man was admitted because of a palpable mass on the antero-lateral side of the right tibia for 3 years. On admission, a well demarcated metastatic pulmonary nodule, measuring 5 cm in diameter, was also identified in the simple chest X-ray. Resection of the lower leg mass revealed typical histologic features of biphasic synovial sarcoma. Aspiration cytology of the pulmonary nodule revealed numerous clusters of spindle cells admixed with groups of epithelial cells. The epithelial cells had moderate-sized, round to oval shaped, and hyperchromatic nuclei. The cytoplasm was clear, but not distinctive. Interspersed tell elements were fibroblast-like spindle cells having elongated hyperchromatic nuclei.

Renal cell carcinoma (RCC) represents 2% to 3% of human cancers and is aggressive, with metastatic capability. The frequent metastatic sites are lung, bone, and liver. Reports of RCC metastatic to skin, and especially scalp are rare. Here we present an 83-year-old woman who was diagnosed with RCC 19 years prior and had a metastatic scalp lesion. An 83-year-old woman presented with a red-to-purple, protruding lesion at the right parietotemporal area. Twenty-three years ago, a right renal mass was incidentally discovered on ultrasound through a routine medical examination. She underwent right nephrectomy for RCC 4 years later. Five months after nephrectomy, new lung nodules were observed. Fifteen years after nephrectomy, metastatic lesions were found in the pelvic bone. She visited dermatology department for evaluation of the new scalp lesion, a year before she first visited our department. Despite chemotherapy, the mass was gradually enlarged. She consulted the plastic surgery department for management of the metastatic RCC was successfully treated with total excision including a 1-cm safety margin, local flap, and STSG coverage. Complete healing was observed, without evidence of recurrence during a 7-month followup. Metastases to the skin are rare, but must be kept in mind because of its high metastatic ability and poor prognosis.

Polymorphous low-grade adenocarcinoma (PLGA) is a neoplasm that is regarded as the second most common malignant salivary gland tumor after mucoepidermoid carcinoma. After the diagnosis of PLGA it is important to make a treatment decision and consider the prognosis. A histopathologic examination is necessary for diagnosis. Treatment is primarily surgical excision and long-term follow up is essential to evaluate local recurrences. This report describes 2 cases of PLGA located in the soft palate without any evidence of metastasis. The first case was PLGA with bony infiltration and an irregular margin lesion. The second case was PLGA localized in palatal soft tissue. We present diagnoses, histopathologic features, treatments and prognosis of PLGA.

The prevalence of breast cancer is very high in Korea. Although the patients receive standard treatments, such as surgery, chemotherapy, or radiotherapy, they frequently experience recurrence or metastasis of their tumors. In addition, many patients with breast cancer also suffer from side effect symptoms induced by these standard treatments. Therefore, increasing numbers of patients now want to undergo treatment with traditional Korean medicine (TKM) in addition to conventional treatment. We present a case of 46-year-old female with recurred breast cancer. She first received two kinds of chemotherapy and then underwent surgery. She then also received 4 cycles of adjuvant chemotherapy. At a follow-up examination, she was informed of recurrent lesions on the right anterior chest wall. She started to receive TKM treatments together with a new chemotherapy. After about one month, the size of the recurred tumor in right chest wall had decreased. Her symptoms, such as shoulder pain, chest pain, and nausea induced by conventional therapy, were also improved. We suggest that a combination of TKM and chemotherapy is a promising treatment for breast cancer.

A 39-year-old male was admitted to Dept. of Thoracic Cardiovasc. Surgery, Korea University Hospital with the chief complaints of progressively enlarged mass on right upper lung which revealed on routine chest P-A since 4 Years ago. Chest PA and tomography revealed well circumscribed huge mass of 7cm. in diameter without invasion on bronchus. so, right upper lobectomy was performed under impression of lung cancer. Postoperative pathologic examination revealed pulmonary blastoma. Pulmonary blastoma is accepted as a distinctive neoplasm recently. One case of typical pulmonary blastoma is reported, and the previous literature is reviewed. There are no specific clinical or radiologic feature of pulmonary blastoma. The presentation is can be that of any other pulmonary tumor although a peripheral situation is usual and a large size is often attained before detection. Pulmonary blastoma is a mixed tumor with malignant epithelial and connective tissue components with a distinctive resemblance to fetal lung. The treatment of choice is surgical excision but the overall prognosis is poor. There is no evidence of recurrence or metastasis on follow-up study during 6 months period after right upper lobectomy.

Inflammatory myofibrolastic tumor (IMT) is a rare borderline neoplasm. It frequently occurs in the lung but occasionally occurs in extrapulmonary sites such as the genitourinary tract, gastrointestinal tract, breast, salivary glands, sinonasal tract, orbit, and the central nervous system. Laryngeal involvement of IMT is very rare. A 61-year-old woman who complained of hoarseness persisting for 3 months visited our hospital. Laryngoscopy showed an elevated lesion in the right true vocal cord. Incisional biopsy was confirmed as larygeal inflammatory myofibrolastic tumor. We performed a transoral excision with CO₂ LASER under suspension examination. Regional recurrence or distant metastasis was not observed after 9 months of follow-up. Herein we report a case of larygeal inflammatory myofibrolastic tumor that was treated with surgery alone, with a literature review.

Purpose: We did a retrospective study to understand the prognostic effects of preoperative blood transfusions in stomach cancer surgery. Materials and Methods: Data for 1,360 patients who underwent gastrectomy for stomach cancer between 2001 and 2009 were retrospectively reviewed. We analyzed factors that affect preoperative transfusion and clinicopathologic features. We also analyzed 5-year and overall survival rates of the transfusion and non transfusion subgroups. Results: Sixty patients (4.4%) required blood transfusion within the preoperative period. The transfused group included patients who took aspirin or clopidogrel (P<0.001), with more advanced T stages (P<0.001), with more advanced nodal metastasis (P=0.00), and with more advanced stages (P=0.00) than the non transfusion group. On multivariate analysis, preoperative transfusion was a statistically significant negative influence on 5-year survival and overall survival rates (58.2% vs 79.9% (P=0.00), 58.2% vs 76.8% (P=0.00)). Applying Cox-regression analyses, blood transfusion did appear to have an effect on prognosis and on 5-year and overall survival rates. Conclusions: We found a direct negative relation between preoperative transfusion and long term prognosis in patients receiving gastric cancer surgery.
