A tracheal tumor is a tumor primarily presenting in the trachea. It may be benign or malignant. [1] 80% of all tracheal tumors are malignant. Among these, the most common are the squamous-cell carcinoma and the adenoid cystic carcinoma.
This classification, based on clinical features, natural history and cellular characteristics, divides vascular anomalies into two groups: vascular tumors and vascular malformations. [5] Although vascular tumors and vascular malformations can resemble each other, there are important differences between both.
A vascular tumor is a vascular anomaly where a tumor forms from cells that make blood or lymph vessels; a soft tissue growth that can be either benign or malignant. [1] Examples of vascular tumors include hemangiomas, hemangioendotheliomas, Kaposi's sarcomas, angiosarcomas, and hemangioblastomas. An angioma refers to any type of benign vascular ...
Laryngotracheal stenosis (Laryngo-: Glottic Stenosis; Subglottic Stenosis; Tracheal: narrowings at different levels of the windpipe) is a more accurate description for this condition when compared, for example to subglottic stenosis which technically only refers to narrowing just below vocal folds or tracheal stenosis.
A common symptom of laryngeal papillomatosis is a change in voice quality. More specifically, hoarseness is observed. [4] [5] As a consequence of the narrowing of the laryngeal or tracheal parts of the airway, shortness of breath, chronic cough and stridor (i.e. noisy breathing which can sound like a whistle or a snore), can be present.
Most initial symptoms of leukemia are related to problems with the bone-marrow function. There are a variety of symptoms that children may experience. The symptoms tend to appear quickly in acute leukemia and slowly over time in chronic leukemia. [1] Symptoms in the different types of childhood leukemia include: feelings of fatigue or weakness
Image shows early occurrence of tracheal deviation. Tracheal deviation is a clinical sign that results from unequal intrathoracic pressure within the chest cavity.It is most commonly associated with traumatic pneumothorax, but can be caused by a number of both acute and chronic health issues, such as pneumonectomy, atelectasis, pleural effusion, fibrothorax (pleural fibrosis), or some cancers ...
A pyogenic granuloma or lobular capillary hemangioma [3] is a vascular tumor that occurs on both mucosa and skin, and appears as an overgrowth of tissue due to irritation, physical trauma, or hormonal factors. [4] [5] It is often found to involve the gums, skin, or nasal septum, and has also been found far from the head, such as in the thigh. [6]
