Specialty. Oncology. Squamous-cell carcinoma ( SCC) of the lung is a histologic type of non-small-cell lung carcinoma (NSCLC). It is the second most prevalent type of lung cancer after lung adenocarcinoma and it originates in the bronchi. Its tumor cells are characterized by a squamous appearance, similar to the one observed in epidermal cells.
The International Classification of Diseases for Oncology ( ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries . It is currently in its third revision (ICD-O-3).
The International Classification of Childhood Cancer (ICCC) is a standardized method for categorizing childhood malignancies set forth by the World Health Organization (WHO). This system bases malignancy classification on the histological traits of the tumor (type of tissue). This is opposed to the classification of adult malignancies, which ...
Cervical intraepithelial neoplasia. Cervical intraepithelial neoplasia ( CIN ), also known as cervical dysplasia, is the abnormal growth of cells on the surface of the cervix that could potentially lead to cervical cancer. [ 1] More specifically, CIN refers to the potentially precancerous transformation of cells of the cervix.
An odontogenic keratocyst is a rare and benign but locally aggressive developmental cyst. It most often affects the posterior mandible and most commonly presents in the third decade of life. [ 1] Odontogenic keratocysts make up around 19% of jaw cysts. [ 2] Despite its more common appearance in the bone region, it can affect soft tissue.
1.8 million (2020) [ 3] Lung cancer, also known as lung carcinoma, is a malignant tumor that begins in the lung. Lung cancer is caused by genetic damage to the DNA of cells in the airways, often caused by cigarette smoking or inhaling damaging chemicals. Damaged airway cells gain the ability to multiply unchecked, causing the growth of a tumor.
In 1994, the Revised European-American Lymphoma (REAL) classification applied immunophenotypic and genetic features in identifying distinct clinicopathologic entities among all the lymphomas except Hodgkin lymphoma. [41] For coding purposes, the ICD-O (codes 9590–9999) [42] and ICD-10 (codes C81-C96) [43] are available.
Mycoplasma is a genus of bacteria that, like the other members of the class Mollicutes, lack a cell wall, and its peptidoglycan, around their cell membrane. [ 1] The absence of peptidoglycan makes them naturally resistant to antibiotics such as the beta-lactam antibiotics that target cell wall synthesis. They can be parasitic or saprotrophic.
