Alveolar soft part sarcoma(ASPS) is a rare malignant neoplasm with a distinct clinicopathologic entity of which fine needle aspiration(FNA) cytologic findings have been described in only a few reports. Although patients usually present with an isolated soft-tissue mass in the extremity, metastasis can occur in about 13 % of total cases and the most frequent metastatic site is the lung. We have recently experienced a FNA cytologic case of ASPS in the lung. A 23-year-old female patient was admitted to this hospital due to 2-month-history of cough She had been good in health before the visit. Chest computed tomography revealed multiple, variable sized, bilateral pulmonary nodules. Physical examination and other staging work up revealed no other lesions except for pulmonary nodules. A percutaneous transthoracic FNA was performed from the pulmonary nodules. The smear was cellular and most cells were arranged singly. In addition, a few clusters lined by thin-walled vasculature with a pseudoalveolar pattern were present. Some of the tumor cells were large and polygonal lo oval with abundant granular or vacuolated cytoplasm. Most cells were naked nuclei showing finely granular chromatin pattern with prominent central nucleoli.

The extranodal non-Hodgkin lymphoma is uncommonly occurred in larynx, accounting for less than 1% of all laryngeal neoplasm. In general, the laryngeal lymphoma is appeared as submucosal mass without mucosal ulceration and is most commonly found in supraglottis. The primary laryngeal lymphoma constitute a diagnostic challenge because they are characterized by absence of clinical and gross differential criteria, compared with squamous cell carcinoma (SCC). We encountered a 74-year-old man with hoarseness and lump sensation in the throat. On direct laryngoscope, multiple ulcerative and exudative mass in glottis and supraglottic areas were observed. The patient was finally diagnosed as large B-cell lymphoma through the laryngeal microsurgery. He received radiation therapy and there is no evidence of recurrence. Although the laryngeal mass has superficial mucosal change, primary laryngeal lymphoma must be included in the differential diagnosis.

Solitary plasmacytoma is a rare malignant neoplasm that originate in immunoglobulin-producing plasma cell. Solitary bone plasmacytoma can be found at any site throughout the skeleton and in most cases eventually progresses to multiple myeloma, of which it is thought to be an unusual presentation. On the other hand, extramedullary plasmacytoma has a tendency to occur in the head and neck region, mainly in association with the upper air passages. Incisional biopsy is the primary approach to make a definitive diagnosis, and immunohistochemical staining can be very helpful in understanding the nature of these tumors. We report a 66 years old patient with solitary bone plasmacytoma and a 36 years old patient with solitary extramedullary plasmacytoma with literatures review.

A solitary fibrous tumor (SFT) is a rare neoplasm originated from the pleura, but they can occur in a variety of extrathoracic regions. Although many cases of primary SFT have been reported, there are extremely rare repots to date of a malignant SFT in the spine or skull. A 54-year-woman visited our hospital due to low back pain and both leg radiating pain. Several imaging studies including magnetic resonance imaging and computed tomography revealed expansive enhanced lesions in the occipital bone, T8, S1-2, and ilium, with neural tissue compression. We performed surgical resection of the tumor in each site, and postoperative radiosurgery and chemotherapy were performed. However, after six months, tumors were recurred and metastasized in multiple regions including whole spine and lung. The authors report here the first case of patient with malignant SFT of tandem lesions in the various bony structures, including skull, thoracic spine, and sacral spine, with a rapid recurrence and metastasis. Although malignant SFT is extremely rare, it should be considered in the differential diagnosis and carful follow-up is needed.

Leiomyosarcoma (LMS) of the small intestine is a rare tumor, accounting for about 1% of all malignant mesenchymal lesions in the gastrointestinal tract. Since small bowel tumors are initially asymptomatic and nonspecific, delayed diagnosis and treatment are common. We found that a 44-year-old male patient who came in for lower abdominal pain had partial obstruction in the small bowel. Multiple ascites and ileal tumors involving peritoneal seeding were observed from his abdominal computed tomography. He was diagnosed as epithelioid LMS involving peritoneal transition after surgical resection, and the outpatient department has planned for a conservative therapy with observation. To the best of our knowledge, ileal epithelioid LMS accompanying a huge omental mass, with a size of 18 cm in dimension, and peritoneal seeding has not yet been reported in Korea. We report this rare case with literature review.

Purpose: The purpose of this study was to examine fatigue, sleep disturbances, and quality of life (QOL) among patients with breast cancer receiving radiotherapy. Methods: A cross-sectional, descriptive design was used. Data were collected through questionnaires distributed to 201 breast cancer patients in a hospital. The data were analyzed using SPSS 21.0. Results: The fatigue scores showed significant differences depending on exercise and duration since diagnosis. The sleep disturbance scores showed significant differences depending on duration since diagnosis. QOL scores showed significant differences depending on exercise, duration since diagnosis, and treatment site. Fatigue and sleep disturbances (r=.40, p<.001) showed statistically significant positive correlations, while fatigue and QOL (r=-.55, p<.001), and sleep disturbances and QOL (r=-.45, p<.001) showed statistically significant negative correlations. The multiple regression analysis, which was used to determine the variables influencing on QOL after radiotherapy, resulted in a significant regression model (F=23.88, p<.001), which accounted for approximately 45% of the explanatory power. Fatigue (${\beta}=-.39$, p<.001) and sleep disturbances (${\beta}=-.27$, p<.001) were revealed to adversely affect quality of life. Conclusion: The nursing intervention is necessary to reduce fatigue and sleep disturbance and to promote exercise in order to enhance QOL of patients with breast neoplasm while receiving radiotherapy.

Nausea and vomiting are common adverse events in chemotherapy. In spite of the serious effects on the quality of life and further treatment, they remain overlooked by physicians, and no standard treatment has been developed. Neurokinin-1 (NK-1) receptor antagonists and palonosetron are the major agents in the standard regimen for treating moderately and highly emetogenic chemotherapy-induced nausea and vomiting (CINV). However, NK-1 receptor antagonists first became commercially available at the end of 2013 and palonosetron has not been extensively applied in China. Olanzapine was recommended as a therapy for moderate and severe CINV in antiemesis-clinical practice guidelines in oncology in 2014 for the first time. It is an atypical antipsychotic agent, which can block multiple receptors on neurotransmitters. During more than 10 years, olanzapine has demonstrated significant effects in preventing CINV and treating breakthrough and refractor CINV, which was observed in case reports, precise retrospective studies, and phase I, II and III clinical trials, with no grade 3 to 4 adverse events. In particular, it is superior to aprepitant and dexamethasone in delayed nausea and vomiting. Therefore, this compound is worthy of further investigation.

Spinal schwannomas are usually extramedullary intradural tumors and their intramedullary localizations are thought to be extremely rare. A 60-year-old woman complaining spastic quadriparesis, voiding difficulty and dyspnea was admitted. Her cervical MRI revealed an intramedullary mass in the cervicomedullary junction with multiple cyst which extended from lower cervical to C3 spinal cord. The mass showed a low signal on T1WI, high signal on T2WI with an wall enhancement. The patient underwent a suboccipital craniectomy and C1-2 laminectomy and the cystic tumor was totally removed through a midline myelotomy. The tumor was proved as an intramedullary schwannoma by pathologic examination. The Intramedullary presence of a tumor arising from the cells of the nerve sheath is unusual, because the central nervous system fibers do not contain the Schwann cell. There have been several hypotheses, but none has been accepted universally. This rare tumor is considered as a curable benign neoplasm, and an accurate intraoperative diagnosis and surgically total removal are essential.

Cementoblastoma is a benign ectomesenchymal odontogenic neoplasm that forms a mass of cementum or cementum-like tissue continuous with the tooth root. Cementoblastoma represents 1% to 6.2% of all odontogenic tumors, and occurs more than 75% arise in the mandible, with most cases arising in the molar and premolar regions. About 75% arises before the age of 30. Radiographically, it appears as a radiopaque mass with a thin radiolucent rim attached to the roots of a tooth. The recurrence rate is 37% in the current study and cortical expansion and perforation of the cortex are common findings in lesions that subsequently recurred. It is apparent that recurrence rate depends largely on the completeness of removal than any other factor. Here we present a 20 year old, female case of an unusual multiple recurrent cementoblastoma around a previous lesion which had been surgically excised 2 years ago.

Distant metastasis from papillary thyroid carcinoma (PTC), particularly from papillary thyroid microcarcinoma, is rare. We present a case of perigastric lymph node metastasis from PTC in a patient with early gastric cancer and breast cancer. During post-surgical follow-up for breast cancer, a 56-year-old woman was diagnosed incidentally with early gastric cancer and synchronous left thyroid cancer. Therefore, laparoscopic distal gastrectomy with lymph node dissection and left thyroidectomy were performed. On the basis of the pathologic findings of the surgical specimens, the patient was diagnosed to have papillary thyroid microcarcinoma with perigastric lymph node metastasis and early gastric cancer with mucosal invasion. Finally, on the basis of immunohistochemical staining with galectin-3, the diagnosis of perigastric lymph node metastasis from PTC was made. When a patient has multiple primary malignancies with lymph node metastasis, careful pathologic examination of the surgical specimen is necessary; immunohistochemical staining may be helpful in determining the primary origin of lymph node metastasis.
