Babak Baban, Olga Golubnitschaja
Flammer syndrome (FS) is a term to blanket a cluster of vascular and nonvascular signs and symptoms linked to primary vascular dysregulation (PVD), increased sensitivity to various stimuli (stress, drugs, etc.) and altered sense regulation such as pain, smell and thirst perception. On one hand, disruption of blood barrier and homeostasis of the body are the main targets of vascular irregularity. Inflammation and immune disorders including autoimmunity are considered as a consequence of the abnormal vascular regulation processes...

Breast adenoid cystic carcinoma (AdCC), a rare type of triple-negative breast cancer (TNBC), has been shown to be driven by MYB pathway activation, most often underpinned by the MYB-NFIB fusion gene. Alternative genetic mechanisms, such as MYBL1 rearrangements, have been reported in MYB-NFIB-negative salivary gland AdCCs. Here we report on the molecular characterization by massively parallel sequencing of four breast AdCCs lacking the MYB-NFIB fusion gene. In two cases, we identified MYBL1 rearrangements (MYBL1-ACTN1 and MYBL1-NFIB), which were associated with MYBL1 overexpression...

Salivary gland neoplasms are a morphologically heterogenous group of lesions that are often diagnostically challenging. In recent years, considerable progress in salivary gland taxonomy has been reached by the discovery of tumor type-specific fusion oncogenes generated by chromosome translocations. This review describes the clinicopathologic features of a selected group of salivary gland carcinomas with a focus on their distinctive genomic characteristics. Mammary analog secretory carcinoma is a recently described entity characterized by a t(12;15)(p13;q25) translocation resulting in an ETV6-NTRK3 fusion...

BACKGROUND: Lactoperoxidase (LPO) is an antimicrobial protein secreted from mammary, salivary and other mucosal glands. It is an important member of heme peroxidase enzymes and the primary peroxidase enzyme present in breast tissues. In addition to the antimicrobial properties, LPO has been shown to be associated with breast cancer etiology. Heterocyclic amines, an important class of environmental and dietary carcinogens, have been increasingly associated with breast cancer etiology. Heterocyclic amines undergo activation in breast tissue as a result of oxidation by LPO...

INTRODUCTION: Whole body PET CT is an important investigation tool in malignancy patients and helps in ascertaining the metabolic activity and exact stage of the disease. However, like any other investigation, false positive results do exist and certain diseases other than cancer may show increased uptake. Hence, a careful evaluation of PET CT and clinical correlation in malignancy patients is a must to accomplish the suitable treatment. METHODS: In this retrospective observational study, seven cases of cancer with concomitant tuberculosis were included...

Heparanase is an endoglucuronidase that uniquely cleaves the heparan sulfate side chains of heparan sulfate proteoglycans. This activity ultimately alters the structural integrity of the ECM and basement membrane that becomes more prone to cellular invasion by metastatic cancer cells and cells of the immune system. In addition, enzymatically inactive heparanase was found to facilitate the proliferation and survival of cancer cells by activation of signaling molecules such as Akt, Src, signal transducer and activation of transcription (Stat), and epidermal growth factor receptor...

Triple-negative breast cancer is viewed clinically as an aggressive subgroup of breast cancer. In fact, most triple-negative breast cancers are poor-prognosis tumors with a complex genomic landscape. However, triple-negative disease is vastly heterogeneous, encompassing multiple entities with marked genetic, transcriptional, histologic, and clinical differences, with neoplasms in this group ranging from low to high grade. Among the less common low-grade triple-negative lesions, two large subgroups, both with a rather indolent behavior, can be distinguished: a low-grade triple-negative breast neoplasia family, which includes nonobligate precursors of triple-negative breast cancer, and, despite being low-grade, harbors the complex genomic landscape of usual triple-negative breast cancer, and the salivary gland-like tumors of the breast, lacking all the cardinal molecular features of conventional triple-negative breast cancer and underpinned by specific fusion genes or hotspot mutations, which may be of diagnostic and possibly therapeutic utility...

Secretory carcinomas of the breast are rare tumors with distinct histologic features, recurrent t(12;15)(p13;q25) translocation resulting in ETV6-NTRK3 gene fusion and indolent clinical behavior. Mammary analog secretory carcinomas arising in other sites are histopathologically similar to the breast tumors and also harbor ETV6-NTRK3 fusions. Breast secretory carcinomas are often triple (estrogen and progesterone receptor, HER2) negative with a basal-like immunophenotype. However, genomic studies are lacking, and whether these tumors share genetic features with other basal and/or triple negative breast cancers is unknown...

Salivary gland carcinomas are rare tumours and therapy strategies are less standardized than in lung, gastric or breast cancer. Therapy is based on surgery, but not all carcinomas are completely resectable, e.g. because carcinomas often show infiltration of nerves. For further therapy decision pathology is recommended, but evaluation of potential targets for personalized therapy is not part of the routine panel. Many salivary gland carcinomas can be resistant to radio- and/or chemotherapy, which limits therapeutic options...

More than 15 years ago, seminal studies by Dr. E. Leon Barnes and colleagues transformed our understanding of salivary duct carcinoma (SDC) and, in doing so, paved the way for contemporary diagnostic and therapeutic approaches to this aggressive salivary adenocarcinoma. In particular, attention to the apocrine phenotype of SDC and expression of androgen receptor (AR) by immunohistochemistry has improved the diagnostic accuracy and showed how SDC can be reliably distinguished from its morphologic mimics (i.e...

Salivary gland cancers comprise a small subset of human malignancies, and are classified into multiple subtypes that exhibit diverse histology, molecular biology and clinical presentation. Local disease is potentially curable with surgery, which may be combined with adjuvant radiotherapy. However, metastatic or unresectable tumors rarely respond to chemotherapy and carry a poorer prognosis. Recent molecular studies have shown evidence of androgen receptor signaling in several types of salivary gland cancer, mainly salivary duct carcinoma...

The natural resources of iodine are seawater, seaweeds and saltpeter-nitrate deposits in Chile. Over 1/3 of the global population is exposed to iodine deficiency, especially in the mountains. Iodine is a component of the thyroid hormones and a strong antioxidant with electric potential of -0.54 V. Iodine as iodide is taken up by the thyroid gland, gastric mucosa, salivary glands and mammary glands in pregnant and breast-feeding women. The transport of iodine to the thyroid gland is regulated by specific enzymes: Natrium-Iodine Symporter, Na+/K+ATP-ase, Pendrin and Apical Iodine Transporter...

A 71-year-old woman, previously treated for malignant lymphoma, was admitted to our hospital with a tumor in the right breast. The tumor size was 2.0 cm in diameter, and the borderline was unclear. The core needle biopsy material revealed an invasive adenocarcinoma with metaplastic change. Right mastectomy and sentinel lymph node biopsy was performed. Histologically, the tumor was composed of mucus-secreting, epidermoid, and intermediate cells. These findings confirmed the diagnosis as mucoepidermoid carcinoma (MEC) of the breast...

BACKGROUND: Secondary malignancies of salivary glands (SMSGs) are among the most common malignant neoplasms to involve the salivary glands. Fine-needle aspiration biopsy (FNAB) of SMSG can present diagnostic challenges. The current report presents the largest such FNAB series to date. METHODS: A search of the pathology database from 6 academic institutions identified 184 FNAB cases of nonlymphomatous SMSG. RESULTS: Of the 184 cases, 171 were of the parotid glands, and 13 were of the submandibular glands; 130 patients were men, and 54 were women, and the mean patient age at diagnosis was 68 years...
