Metastatic tumor is one of several etiologies of space-occupying masses in the orbit that accounts for 1-13% of all orbital masses. In the adult patient population, breast cancer is the most common tumor to metastasize to the orbit, followed by metastasis from the lung, prostate, and gastrointestinal tract. Carcinoid tumors are rare neuroendocrine neoplasms derived from enterochromaffin cells, which are found primarily in the gastrointestinal tract and bronchial tree. Liver metastases are the classic presentation of distant disease...

Purpose Childhood cancer survivors (CCSs) are at increased risk for subsequent malignant neoplasms (SMNs). We evaluated the long-term risk of SMNs in a well-characterized cohort of 5-year CCSs, with a particular focus on individual chemotherapeutic agents and solid cancer risk. Methods The Dutch Childhood Cancer Oncology Group-Long-Term Effects After Childhood Cancer cohort includes 6,165 5-year CCSs diagnosed between 1963 and 2001 in the Netherlands. SMNs were identified by linkages with the Netherlands Cancer Registry, the Dutch Pathology Registry, and medical chart review...

We present a case of cutaneous apocrine carcinoma arising in the axilla of a 71-year-old man. The tumor had a significant component of histiocytoid and signet-ring cells as well as in situ carcinoma within the apocrine glands. The cells expressed GATA3, gross cystic disease fluid protein 15, androgen receptor, and E-cadherin. Estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 were negative. Clinical correlation was required to rule out a metastasis from the breast or the gastrointestinal tract...

Papillary and pseudopapillary features are histopathologic findings typically associated with carcinomas (thyroid, pancreas, breast, prostate, bladder, kidney, or ovary) or mesothelioma. Melanoma is typically composed of nested and variably pigmented atypical cells. Here, we report a case of in-transit metastasis of melanoma presenting with prominent papillary features, and we discuss the differential diagnoses of neoplasms with papillary features. This case report suggests that the spectrum of neoplasms with papillary features should be expanded to include melanoma, a pattern that, to the best of our knowledge, is uncommon...

Myofibroblast differentiation plays an important role in the malignant progression of phyllodes tumor (PT), a fast-growing neoplasm derived from periductal stromal cells of the breast. Macrophages are frequently found in close proximity with myofibroblasts, but it is uncertain whether they are involved in the myofibroblast differentiation during PT progression. Here we show that increased density of tumor associated macrophage (TAM) correlates with malignant progression of PT. We found that TAM stimulated myofibroblast differentiation and promoted the proliferation and invasion of PT cells...

PURPOSE: The development of improved diagnostic techniques, increased survival, and life expectancy of cancer patients have all contributed to the higher frequency of multiple primary malignant neoplasms (MPMN). MPMN can be divided into two main categories: Synchronous MPMN (sMPMN) and metachronous MPMN (mMPMN). MATERIALS AND METHODS: 122 patients with MPMN analyzed retrospectively who were admitted to the Radiation Oncology Department of Eskisehir Osmangazi University Medical Faculty from January 2004 to December 2013...

PURPOSE: Li-Fraumeni syndrome (LFS) is a rare genetic disease with strong predispositions to multiple early-onset neoplasms, mostly sarcomas, breast cancers, brain tumors and adrenocortical carcinomas (LFS core cancers). In most LFS families the germline mutations of TP53 tumor suppressor gene were found. Lung cancer does not belong to the core cancers of LFS, however its higher incidence is observed in families with TP53 mutations. Our aim was to search for TP53 mutations in female lung cancer patients whose clinico-demographic characteristics suggested a probable genetic predisposition to the disease...

Polarizable calcium oxalate (CaOx) crystals have been well documented in breast biopsies, generally associated with benign apocrine metaplasia. In contrast, polarizable crystals are only rarely reported in skin adnexal neoplasms. We report three different cases of sweat gland tumors with polarizable crystals morphologically suggestive of CaOx: 1 apocrine hidrocystoma and 2 tubular apocrine adenomas. The histologic features were examined in 3 cases. Clinical presentation summary included 2 males and 1 female, ages 53 to 74, with lesions located on the left cheek, inferior vertex scalp and the left eyebrow...

Lung carcinoid tumors account for approximately 2% of lung cancers, with 10% of the tumors represented by the atypical type. While atypical carcinoids are metastatic to intrathoracic lymph nodes in approximately half of the cases on the initial presentation, distant metastases are seen in only 20% of the patients and are found most frequently in bones, liver, adrenal glands, and brain. We present a case of an unusual metastatic disease to the breast in 51-year-old female who developed a new breast mass 2 years after left lower lobectomy due to atypical carcinoid tumor...

Breast metastases from extramammary cancers are rare and usually related to poor prognosis. The extramammary tumors most frequently exhibiting breast metastases are melanoma, lymphomas, ovarian cancer, lung, neuroendocrine tumors, and sarcomas. Due to the lack of reliable and specific clinical or radiological signs for the diagnosis of breast metastases, a combination of techniques is needed to differentiate these lesions from primary breast carcinoma or even benign breast lesions. Multiple imaging methods may be used to evaluate these patients, including mammography, ultrasound, magnetic resonance imaging (MRI), computed tomography (CT) and positron emission tomography (PET/CT)...

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer tumors. Comparisons between TNBC and non-triple negative breast cancer (nTNBC) may help to differentiate key components involved in TNBC neoplasms. The purpose of the study was to analyze the expression profile of TNBC versus nTNBC tumors in a homogeneous population from northeastern Mexico. A prospective study of 50 patients was conducted (25 TNBC and 25 nTNBC). Clinic parameters were equally distributed for TNBC and nTNBC: age at diagnosis (51 vs 47 years, p=0...

BACKGROUND: Heat shock protein (HSP90) is a molecular chaperone involved in maintaining protein homeostasis by modulating stability of de novo synthesized proteins. Neoplastic cells with high metabolic rate have higher expression of HSP90 and develop so called "chaperone addiction". Specific inhibition of HSP90 has been therefore discussed as a viable therapeutic strategy and several inhibitors of HSP90 have already entered clinical trials. Recently, a novel role for HSP90 was found on plasma membrane of cancer cells...

In recent years, more and more studies have indicated that microRNAs (miRNAs) play critical roles in various complex human diseases and could be regarded as important biomarkers for cancer detection in early stages. Developing computational models to predict potential miRNA-disease associations has become a research hotspot for significant reduction of experimental time and cost. Considering the various disadvantages of previous computational models, we proposed a novel computational model based on super-disease and miRNA for potential miRNA-disease association prediction (SDMMDA) to predict potential miRNA-disease associations by integrating known associations, disease semantic similarity, miRNA functional similarity, and Gaussian interaction profile kernel similarity for diseases and miRNAs...

Giant phyllodes tumors (PT) are an uncommon fibroepithelial neoplasm and especially rare in adolescent girls. Diagnosis is difficult not only due to the rarity of PT, but also owing to the resemblance of its clinical and imaging features with fibroadenoma. The author reports a case of a giant PT in a 14-year-old girl. Clinical examination showed a large painful mass in the left breast, and an abscess was initially suspected. But magnetic resonance imaging (MRI) displayed features characteristic of PT. Following complete surgical excision of the mass, histopathology confirmed the diagnosis of a benign PT with diffuse myxoid changes, consistent with the MRI findings...

Synchronous bilateral breast cancer is rare, and oncocytic carcinoma is an even rarer breast cancer histological subtype. In general, oncocytic tumors are defined as neoplasms with eosinophilic granular cytoplasm and have been reported in various organs. Oncocytic carcinoma of the breast was first documented by Gădăleanu and Craciun in 1987, and 48 cases have since been reported. The present study reports a case of synchronous bilateral breast oncocytic carcinoma. The patient was a 78-year-old woman. Although she exhibited no symptoms, chest computed tomography revealed three multinodular breast tumors: Two in the right breast and one in the left...

Breast metastases of solid extramammary tumors are very rare in comparison to primary malignancies of the breast and account for only 0.33-6.3% of all malignant neoplasms of the breast. The most common primary tumors are malignant melanoma, distant sarcomas, lung cancer, ovarian cancer, renal cell cancer and thyroid cancer in decreasing order of frequency. This review article summarizes the clinical features and the different imaging findings of breast metastases from different extramammary solid tumors. Breast metastases are often incidental findings in computed tomography (CT) or positron emission tomography CT (PET-CT) imaging...

Granular cell tumor (GCT) is a rare neoplasm of the soft tissues, and <1% of all GCTs are malignant. It usually appears in the tongue and sometimes may affect the female breast. Initially, GCT was considered to be a myogenic lesion affecting female breast (myoblastoma). Actually, it is assumed as a tumor originating from perineural or putative Schwann cells of peripheral nerves or their precursors that grows in the lobular breast tissue, due to the immunohistochemical features. Here, we review the importance of differentiating between this tumor and malignant breast carcinoma...

Dermatofibrosarcoma protuberans (DFSP) is an uncommon slow growing neoplasm of the dermis with tendency to invade the subcutaneous tissues. It presents during the third to fourth decade of life and is commonly seen over the trunk, extremities and head and neck. DFSP presenting as a breast lump is rare but few cases have been reported in the literature. Pre-operative diagnosis with mammography, ultrasonography and FNAC is challenging. We report a case of a DFSP of the right breast in a middle aged lady with history of recurrent breast lumps excised and diagnosed in the past as benign...
