Atypical Pulmonary Carcinoid Tumor
Atypical pulmonary carcinoid tumour is a subtype of pulmonary carcinoid tumor Pulmonary carcinoid tumour is a neuroendocrine tumour of the lung. There are two types: * Typical pulmonary carcinoid tumour * Atypical pulmonary carcinoid tumour Atypical pulmonary carcinoid tumour is a subtype of pulmonary carcinoid tumor. .... It is an uncommon low-grade malignant lung mass that is most often in the central airways of the lung. It is also known as "atypical lung carcinoid tumour", " atypical lung carcinoid" or "moderately differentiated neuroendocrine carcinoma". It is a more aggressive than typical carcinoid tumors: nodal metastases in 70% vs. 5%. The 5 year survival is 49-69%. Atypical carcinoid tumors have increased mitotic activity (2-10 per 10 HPF), nuclear pleomorphism or foci of necrosis. __TOC__ Morphological differential diagnosis * Typical pulmonary carcinoid tumor ** Typical pulmonary carcinoid lacks comedo-like necrosis, and has < 0.2 mitotic figures/HPF.

High Power Field
A high-power field (HPF), when used in relation to microscopy, references the field of view under the maximum magnification power of the objective being used. Often, this represents a 400-fold magnification when referenced in scientific papers. Area Area per high-power field for some microscope types: *Olympus BX50, BX40 or BH2 or AO: 0.096 mm2 *AO with 10x eyepiece: 0.12 mm2 *Olympus with 10x eyepiece: 0.16 mm2 *Nikon Eclipse E400 with 10x eyepiece and 40x objective: 0.25mm2 *Leitz Ortholux: 0.27 mm2 *Leitz Diaplan: 0.31 mm2 Examples of usage The area provides a reference unit, for example in reference ranges for urine tests.Normal Reference Range Table from the |

Typical Pulmonary Carcinoid Tumor
Typical pulmonary carcinoid tumour is a subtype of pulmonary carcinoid tumour. It is an uncommon low-grade malignant lung mass that is most often in the central airways of the lung. Signs and symptoms Lung carcinoids typically present with a cough or hemoptysis. Findings may closely mimic malignant tumours of the lung, i.e. lung cancer. Diagnosis The definitive diagnosis is rendered by a microscopic examination, after excision. Typical carcinoids have cells with stippled chromatin and a moderate quantity of cytoplasm. They typically have few mitoses and lack necrosis. By definition, they are greater than 4 mm in largest dimension; smaller lesions are referred to as ''pulmonary carcinoid tumourlets''. The differential diagnosis of typical pulmonary carcinoid tumour includes: ''atypical pulmonary carcinoid tumour'', ''pulmonary carcinoid tumourlet'' and ''lung adenocarcinoma''.

Lung Disorders
Respiratory diseases, or lung diseases, are pathological conditions affecting the organs and tissues that make gas exchange difficult in air-breathing animals. They include conditions of the respiratory tract including the trachea, bronchi, bronchioles, alveoli, pleurae, pleural cavity, the nerves and muscles of respiration. Respiratory diseases range from mild and self-limiting, such as the common cold, influenza, and pharyngitis to life-threatening diseases such as bacterial pneumonia, pulmonary embolism, tuberculosis, acute asthma, lung cancer, and severe acute respiratory syndromes, such as COVID-19. Respiratory diseases can be classified in many different ways, including by the organ or tissue involved, by the type and pattern of associated signs and symptoms, or by the cause of the disease. The study of respiratory disease is known as pulmonology. A physician who specializes in respiratory disease is known as a pulmonologist, a chest medicine specialist, a respiratory ...
