Tailgut cysts are uncommon developmental cysts that form in the presacral space. Complications of tailgut cysts include benign reactive lesions associated with infection and inflammation, and malignant transformation. Six cases of carcinoid tumor arising in tailgut cysts have been reported in the medical literature to date. Here we report another case of carcinoid tumor arising in a tailgut cys...

BACKGROUND Carcinoid heart disease is a frequent complication of carcinoid syndrome. It is related to the release by the carcinoid tumor and/or its metastases of bioactive substances such as serotonin. It is characterized by right-sided valvular involvement and can lead to right-sided heart failure. It is a prognostic factor of carcinoid syndrome. CASE PRESENTATION We report the case of a 53-...

BACKGROUND Lung carcinoid tumor and low grade glioma are two uncommon malignancies. PATIENTS AND METHODS We report the case of 24-year-old man who presented with respiratory disease. Imaging investigations showed a right lung tumor and histological analysis confirmed a typical carcinoid tumor. As part of initial staging, brain MRI revealed an asymptomatic right frontal lesion. First, a right ...

Salivary gland tumors account for 3 to 6% of all head and neck neoplasms in adults. Some 70 to 85% of these lesions are found in the parotid. Carcinoid tumors, which represent a distinct and relatively uncommon subset of neuroendocrine tumors, are most commonly found in the gastrointestinal tract, although in rare cases they are known to occur in extragastrointestinal locations, including the l...

Carcinoid tumors of the lung are rare neuroendocrine tumors that make up approximately 1 to 2% of all lung neoplasms. These tumors overexpress somatostatin receptors, and somatostatin analog therapy has become standard in the treatment of carcinoid tumors. In addition, radiolabeled somatostatin analogs have been used to diagnose and treat these lesions. We describe the case of a patient with a ...

An anterior mediastinal tumor was detected in a 45-year-old female during a medical checkup. Chest computed tomography (CT) showed the anterior mediastinal tumor and a pulmonary tumor in the right lower lobe. Furthermore, tumors of the parathyroid gland, pancreas, and pituitary gland were also detected. She was clinically diagnosed with multiple endocrine neoplasia type1 (MEN1). The patient und...

BACKGROUND Metastatic breast carcinoids are rare neoplasms. They can be mistaken for primary breast carcinoma both clinically and radiologically, even with known history of carcinoid tumor elsewhere in the body. CASE PRESENTATION We report a case of unilateral breast metastasis from carcinoid tumor of the small intestine in a 52-year-old woman who was successfully treated by lumpectomy and ra...

Rheumatoid arthritis (RA) is a chronic, autoimmune disease of unknown etiology, characterized by symmetrical polyarthritis resulting in damage to cartilage and bone. It is estimated to have a worldwide prevalence of 1%, with a 2to 3-fold excess in females and a peak in prevalence between the ages of 45 and 54 years (1). Several studies have described an increased risk of malignancy in subjects ...
