Clinicians should looking for techniques that helps to early diagnosis of cancer, because early cancer detection is critical to increase survival and cost effectiveness of treatment, and as a result decrease mortality rate. Medical images are the most important tools to provide assistance. However, medical images have some limitations for optimal detection of some neoplasias, originating either from the imaging techniques themselves, or from human visual or intellectual capacity. Image processing techniques are allowing earlier detection of abnormalities and treatment monitoring. Because the time is a very important factor in cancer treatment, especially in cancers such as the lung and breast, imaging techniques are used to accelerate diagnosis more than with other cancers. In this paper, we outline experience in use of image processing techniques for lung and breast cancer diagnosis. Looking at the experience gained will help specialists to choose the appropriate technique for optimization of diagnosis through medical imaging.

A rotator cuff tear causes shoulder pain and limits movement of the shoulder joint. A chronic degenerative change or impingement is the reason for a rotator cuff tear. Diagnosis is made based on medical history and, physical and radiological examinations. Other causes of shoulder pain include calcific tendinitis, degenerative arthropathy, joint dislocation, fracture, and primary or metastatic neoplasm. However, metastatic cancer in the shoulder joint is difficult to diagnosis. We experienced a case in which a 46-year-old female patient complained of left shoulder pain and limited joint mobility, and these symptoms were due to metastatic breast cancer in the shoulder.

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.

Metastasis from primary cancer to the thyroid is uncommon in breast cancer. Here we present a case of lobular breast carcinoma that metastasized to the thyroid. A 54-year-old woman without symptoms was admitted to our institution for staging of the lymph node above the left clavicle. An $^{18}F$-fluoro-deoxy-D-glucose positron emission tomography scan was performed for staging, and low uptakes were observed in the left supraclavicular and cervical lymph nodes. High uptake was seen in the posterior and lower left lobe of the thyroid. Histologic findings indicated lobular breast carcinoma (positive GATA3, loss of E-cadherin expression) metastatic to the thyroid with a luminal profile. Immunohistochemical analysis was negative for primary thyroid or parathyroid carcinoma. To our knowledge, this is the first report of a patient presenting a metastatic invasive lobular carcinoma in the thyroid and lymph nodes without a prior diagnosis of breast cancer.

Cystic hypersecretory carcinoma of the breast is a rare variant of ductal carcinoma of breast, first described in 1984 by Rosen and Scott. Histologically, it is characterized by the formation of dilated ducts and cysts containing an eosinophilic secretory product resembling thyroid colloid. Cytologic findings show a few clusters of atypical ductal epithelial cells in amorphous proteinaceous material with clacking artifact. Differential diagnosis include mucinous carcinoma and benign mucocele-like tumor. We present two cases of fine needle aspiration cytology of cystic hypersecretory intraductal carcinoma of the breast with a review of the literature.

Tumors that metastasize to the pituitary gland are unusual, and are typically seen in elderly patients with diffuse malignant disease. The most common metastases to the pituitary are from primary breast and lung cancers. We report a 65-year-old woman with pituitary metastasis from breast cancer who presented with recent-onset left progressive deterioration of visual acuity and visual field. The clinical diagnosis was made after brain and sellar magnetic resonance imaging showed a large sellar mass compressing the optic chiasm and invading the pituitary stalk. An otorhinolaryngology and neurosurgery team removed the tumor via a transsphenoidal approach, and this procedure obtained symptomatic relief. Postoperatively, metastasis from breast invasive ductal adenocarcinoma was confirmed histologically. We report this unusual case with a review of the relevant literature.

A 43-year-old woman with breast cancer who was on neoadjuvant chemotherapy presented with cough, sputum and mild fever. High-resolution computed tomography showed diffuse ground glass opacities in bilateral lungs and subpleural patchy consolidations. Initially, she was thought to have pneumonia or interstitial lung diseases such as drug-induced pneumonitis and treated with antibiotics and steroids. She subsequently got breast cancer surgery because of disease progression, and concurrent thoracoscopic lung biopsy revealed metastatic carcinoma of the lung from breast cancer. The diagnosis of suspected interstitial lung disease can be made without lung biopsy, but malignancy should always be considered and lung biopsy should be performed in the absence of a definitive clinical diagnosis.

신경내분비 유방암은 드물게 발생하며 고유한 특징을 가진 원발성 유방암의 아형으로서, 정확한 진단을 위해서는 면역조직화학염색법이 필요하다. 현재까지는 이 질환의 임상적 특징이나 예후, 올바른 치료에 대한 정확한 이해가 부족한 상태이며, 원발성 신경내분비 유방암의 영상의학적 소견은 소수의 증례에서만 보고되었다. 본 증례에서는 국소적 진행과 전이를 보인 원발성 신경내분비 유방암의 영상 소견을 보고하고자 한다.

유방을 침범하는 혈액종양은 굉장히 드물게 보고되었다. 우리는 유방의 다발성 결절로써 재발한 급성 골수성 백혈병의 증례를 보고하고자 한다. 77세 여자 환자가 양측 유방의 촉지되는 다발성 결절로 외래를 내원하였다. 환자는 급성 골수성 백혈병(acute myeloid leukemia; 이하 AML)으로 진단받고 9차례의 항암치료 이후 완전 관해가 된 병력이 있었다. 유방 촬영과 유방 초음파에서 환자의 촉지성 병변이 영상의학적으로 확인되었으며 액와부 림프절 종대도 동반되었다. 총생검으로 얻은 검체는 면역화학염색을 통해 AML과 blastic plasmacytoid dendritic cell neoplasm의 형태를 보였으며 추후 진행한 골수 생검에서 AML로 확인되었다. 이렇듯 굉장히 드물지만, 혈액암의 병력을 가진 환자가 유방의 촉지성 종괴로 내원하였다면 담당의는 적절한 조직검사 및 면역화학검사로 정확한 진단을 하여 환자가 적절한 치료를 받도록 해야 한다.

목적 : 유방암을 진단 받은 환자의 자기공명영상에서 추가적으로 발견된 유두상 병변의 자기공명영상 소견과 수술적 절제 후 상향화 비율을 알아보고자 한다. 대상 및 방법 : 본원에서 유방암 진단된 환자의 수술 전 자기공명영상 1729건에서 지표 종양 외에 악성 의심 조영증강을 보인 병변 중 초음파 유도하 핵생검에서 유두 종양으로 진단된 21명의 환자의 22개 병변을 대상으로 하였다. 이 중 수술적 절제를 시행한 병변은 핵생검 결과와 절제 생검 결과를 비교하였다. 또한 이 병변들의 자기공명영상 소견을 BI-RADS MRI lexicon에 따라 후향적으로 분석하여 특징을 알아보았다. 결과 : 자기공명영상에서는 종괴 8예, 비종괴 7예, 초점 7예로 관찰되었고 초점으로 나타난 병변은 병리 조직에서 모두 (100%) 양성 병변으로 진단되었고, 역동적 조영증강 검사에서 고원형과 세척형 양상을 보였다. 양성 유두종 1예 (11.1%), 비정형요소를 가진 유두 종양 3예 (100%), 유두 종양 3예 (60%)가 수술적 절제 후 관상피내암, 침윤성 관상피암, 침윤성 소엽암 등으로 상향화되었다. 결론 : 초음파 유도하 핵생검에서 유두상 병변으로 진단된 병변들의 자기공명영상 소견은 양성과 악성을 예측하기에 특징적인 차이점을 보이지 않아 영상소견만으로 양성과 악성을 구분할 수 없으며 다수에서 수술적 절제 후 조직학적 상향화를 보여 (41.2%, 7/17) 반드시 수술적 절제를 통한 확진이 필요할 것이다.
