Extranodal presentation, especially in breast parenchymal tissue, is rare. A 54-year-old woman presented with a painful and palpable lump in the right breast. Ultrasonography revealed an irregular, indistinct, hypoechoic mass with a hyperechoic halo. Pathological analysi…
  • [Clinical analysis of head and neck neurogenic tumor in childhood]. [Journal Article]
    Lin Chung Er Bi Yan Hou Tou Jing Wai Ke Za Zhi 2019; 33(10):983-986Li YZ, Liu YW, … Ni X
  • CONCLUSIONS: Neuroblastoma is the most common neurogenic tumor in the head and neck of children. Most neurogenic tumors have their corresponding characteristics on imaging and should be differentiated. Schwannoma has clear boundary and intact capsule, so it is easier to complete resection. The neurofibroma is commonly difficult to remove with safety margin because of its unclear boundaries. Neuroblastoma should be treated according to the lesion range and stage. Most of the lesions are difficult to remove completely due to the wide range, peripheral blood vessels and important nerves. So preoperative chemotherapy is generally required.
  • Atypical Presentation of a Medullary Thyroid Carcinoma Producing Acth and Serotonin. [Case Reports]
    Case Rep Oncol 2019 Sep-Dec; 12(3):742-748Ferreira M, Leal CTS, … Costa MB
  • Medullary carcinoma accounts for about 5% of all thyroid malignancies. The tumor may produce other hormones in addition to calcitonin that typically occurs in the presence of distant metastases. The aim of this report is to present a case of invasive medullary thyroid carcinoma producing ACTH and serotonin. A male patient sought medical attention due to facial plethora and distal paresthesia. On …
  • Adenoid Cystic Carcinoma of the Breast: A Case Report. [Case Reports]
    Case Rep Oncol 2019 Sep-Dec; 12(3):698-703Kashiwagi S, Asano Y, … Ohira M
  • Adenoid cystic carcinomas (ACCs) are malignant tumors that most often occur in the salivary glands and bronchi, with occurrence in the breast being rare. ACCs of the breast reportedly give rise to few lymph node metastases or distant metastases and have a favorable prognosis. A 56-year-old woman with a left breast mass identified by mammographic screening was examined at our institute. Breast ult…
  • Occult breast cancer in a female with benign lesions. [Letter]
    J Cancer Res Ther 2019 Jul-Sep; 15(5):1170-1172Di Chio F, Santangelo G, … Guglielmi G
  • Occult breast cancer is a carcinoma discovered by the presence of axillary lymph node metastases without the detection of the primary breast tumor. The incidence of this very rare pathology is 0.3%-1.0%. The limited number of these cases does not allow for the precise management of this rare pathology and often, the breast cancer manifestation can take many years to become obvious. We report the …

  • Glomus tumor (GT) is one of the rarest gastrointestinal soft tissue neoplasms. GT in the esophagus has been scarcely reported, and only less than ten cases have been reported. Herein, we report another case of asymptomatic esophageal GT. A 30-year-old male patient was admitted due to incidental finding of esophageal mass on gastroscopy examination. Gastroscopy examination revealed an esophageal m…

  • A 14-year-old cat was presented with a 2-week history of ataxia, seizure-like episodes, vomiting and weight loss. Serum biochemistry revealed severe hypoglycaemia, associated with low serum fructosamine and high insulin concentrations. On abdominal ultrasound, a focal hypoechoic well-defined mass in the left limb of the pancreas was identified and the presence of an additional smaller nodule was …

  • A Caucasian man 64 years old was admitted to our department for fever, strangury, frequency and pain in the perineum secondary to the relapse of Cowper's gland abscess previously treated by antibiotic therapy and trans-perineal ultrasound-guided aspiration. At admission, the clinical parameters were suggestive of sepsis; moreover, the trans-perineal ultrasound detected an hypoechoic mass suspicio…
