Parathyroid cancer is a rare endocrine malignancy, representing less than 1 % of all cases of primary hyperparathyroidism. The exact etiology of the disease remains unknown. Known risk factors include neck irradiation, end stage renal failure, genetic factors, particularly the the HPRT2/CDCT73 gene mutation. The clinical picture is often indolent, yet progressive with a trend of local invasion and metastasis formation in advanced disease. The clinical picture includes symptoms of severe and resistant hypercalcemia, requiring intensive therapy often with the need of dialysis...

Because there is no screening test for ovarian cancer, effective prevention strategies may be the best way to reduce the mortality of this most lethal gynecologic malignancy. Increasing evidence supports the hypothesis that the fallopian tube is the site of origin for the vast majority of high-grade serous carcinomas. Our growing understanding of the pathogenesis of this disease offers a rare opportunity to explore new preventive measures, such as bilateral salpingectomy, which may provide great benefit without compromising ovarian function...

Regeneration in mammals is restricted to distinct tissues and occurs mainly by expansion and maturation of resident stem cells. During regeneration, even subtle mutations in the proliferating cells may cause a detrimental effect by eliciting abnormal differentiation or malignant transformation. Indeed, cancer in mammals has been shown to arise through deregulation of stem cells maturation, which often leads to a differentiation block and cell transformation. In contrast, lower organisms such as amphibians retain a remarkable regenerative capacity in various organs, which occurs via de- and re-differentiation of mature cells...

Patients with inflammatory bowel disease (IBD) may develop, similarly to individuals from general population, rare cases of HPV-related anal canal squamous cell carcinoma (SCC) and their intra-epithelial precursor lesions, as well as very rare cases of anal canal adenocarcinoma. Patients with chronic perianal Crohn's disease (CD) are at substantial risk of developing SCC or adenocarcinoma from the fistula-lining epithelium, as well as SCC or adenocarcinoma arising from chronic anorectal ulcerations or strictures...

Circulating tumour cells (CTCs) are rare tumour cells found in the circulatory system of certain cancer patients. The clinical and functional significance of CTCs is still under investigation. Protein profiling of CTCs would complement the recent advances in enumeration, transcriptomic and genomic characterization of these rare cells and help define their characteristics. Here we describe a microfluidic western blot for an eight-plex protein panel for individual CTCs derived from estrogen receptor-positive (ER+) breast cancer patients...

As a medical student, I have now almost 6 years of academic studies and clinical interaction with numerous patients, though sometimes brief and superficial. I have found that sometimes it is truly hard to grasp how humane a person is behind their sickness. Fortunately, I have been hitherto able to avoid the almost natural desensitization our degree imposes upon us, either through my own process of thought or through a kind warning of some of "my" patients. Having been particularly thrown aback by the keen eye of a patient I had the opportunity to meet in an Oncology ward, I realized that I had much more to consider when studying a clinical case and that rarely a cancer (or a disease whatever it may be) is but a cancer...

INTRODUCTION: Port site metastasis after laparoscopic surgery for cervical cancer is a rare phenomenon. METHODS: We present a case report of isolated port site recurrence 4 years following laparoscopic surgery in a patient with node-negative, clinical stage IB1 cervical adenocarcinoma. RESULTS: A 44 year-old woman presented with a necrotic cervical lesion. A biopsy of the mass revealed invasive endocervical adenocarcinoma. She underwent a robotic-assisted radical hysterectomy, bilateral salpingectomy, and pelvic lymph node dissection with bilateral oophoropexy...

External jugular vein thrombosis is a rare vascular event which may lead fatal complication such as sepsis and pulmonary embolism. Its relation to the visceral solid tumor as an etiologic factor has been established well. Although external jugular vein thrombosis may be seen in malignancy, it is unusual to see as a sign of breast cancer. Most of the external jugular vein thrombosis occurs secondary to compression of the vein. Vascular thrombosis due to hypercoagulability is known as Trousseau syndrome. Herein, we present a case of metastatic breast cancer which presented with external jugular vein thrombosis; Trousseau syndrome...

One of the rare but most challenging issues in the management of the locally-advanced breast cancer (LABC) is life-threatening bleeding from the fungating and/or ulcerating focus (foci) of these tumors. Breast surgeons may need the assistance of interventional radiologists to solve this urgent condition if surgery cannot provide sufficient benefit. Herein, we report a case of recurrent locally-advanced breast cancer that presented with sudden severe bleeding, which was stopped by an interventional radiologist via transcatheter arterial embolization (TAE)...

A woman aged 50 years was diagnosed as having an invasive ductal carcinoma in the right breast and ductal carcinoma in situ in the left breast and underwent bilateral mastectomy eight years ago. A mass was identified during follow-up in positron-emission tomography (PET) image in the left infraclavicular region, indicating metastasis. Histopathologic examination showed a mass of 1.9 × 1 × 0.7 cm in dimensions characterized by spindle or round nuclei cells that formed island or cords in hyaline and myxoid ground and intracytoplasmic vacuoles containing erythrocytes...

We report a case of adenocarcinoma affecting the chin of a 48-year-old man. The tumor showed signs of apocrine differentiation and had infiltrated the muscle. The patient had no history or clinical evidence of breast cancer. We made a diagnosis of cutaneous apocrine adenocarcinoma. Apocrine adenocarcinoma rarely arises in areas with scarce apocrine glands. We reviewed the literature on apocrine adenocarcinoma of the face in areas other than the eyelids and auditory canal, where specialized apocrine glands are present...

Primary breast lymphoma is a rare disease and accounts for 0.5% of cases of breast cancer. Most primary breast lymphomas develop from B cells, and the involvement of T cells is rare. Anaplastic large cell lymphoma (ALCL) is a recently discovered T-cell lymphoma associated with breast implants. Only a few cases have been reported to date. It is believed that the incidence of ALCL is increasing because of the increasing number of breast implants. The clinical presentation is variable and can manifest as a palpable mass in the breast or armpit, breast pain, or capsular contracture...

Anaplastic large-cell lymphoma (ALCL) is a rare type of highly malignant, non-Hodgkin lymphoma (NHL). Currently, only studies on the chimeric oncogene NPM-ALK have reported a link to ALCL progression. However, the specific molecular mechanisms underlying the invasion of ALCL are still unclear. Here, we sought to investigate differentially expressed, long non-coding RNAs (lncRNAs) in ALCL and their potential biological function. Our microarray analyses revealed that LINC01013, a novel non-coding RNA gene, was highly expressed in clinical specimens of ALCL and was significantly upregulated in invasive ALCL cell lines...

The management of soft tissue sarcoma is challenging and varied. Centralisation of management in high volume specialist centres has revolutionised outcomes. Surgery remains the mainstay of treatment and is currently the only potentially curative therapy. Retroperitoneal soft tissue sarcoma presents a particular challenge to the surgical oncologist and the concept of extended resection to include surrounding expendable organs taken en bloc with the tumour has now largely been adopted. The use of neoadjuvant and adjuvant therapies for retroperitoneal soft tissue sarcoma is still to be established, although they are employed on a case-specific basis...

In this case report we present a 14-year-old boy with two testicles in the right hemiscrotum - a case of polyorchidism. He did not have surgery for his condition, and his condition was followed according to the guidelines. In a study, 6.4% of cases with polyorchidism were found to contain neoplasms of which the most were malignant. If the supernumerary testicle is not contributing to the spermatogenesis, it is therefore recommended to remove the testicle. Otherwise, recommendations are a yearly follow-up by Doppler ultrasound, including a physical examination to discover development of cancer...

BACKGROUND: Accurate measurement of tumor burden in breast cancer disease is essential to improve the clinical management of patients. In this study, we evaluate whether the fluctuations in the fraction of PIK3CA mutant allele correlates with tumor response according to RECIST criteria and tumor markers quantification. METHODS: Eighty six plasma samples were analyzed by digital PCR using Rare Mutation Assays for E542K, E545K and H1047R. Mutant cfDNA and tumor markers CA15-3 and CEA were compared with radiographic imaging...
