Abstract:
The behavior of the pathological subtypes of tracheal glomus tumor (benign, uncertain malignant potential UMP, malignant) is vague. In a 51-year-old gentleman, suffering from cough for 4 months, computed tomography scan showed a mass at lower third of the trachea and the bronchoscope revealed exophytic mass at the tracheal lumen. Segmental tracheal resection was done using special modified endotracheal tube for the distal lung ventilation. The tracheal glomus tumor was also diagnosed based on the immunohistochemical staining. The tumor was 2 cm in diameter, deeply located, mitotic phase was difficult to identify, and a diagnosis of UMP subtype was made. There was no recurrence after 2 years follow-up. This is the first reported case of UMP subtype in lower trachea and we studied the treatment options with the clinic-pathological behavior of this tumor and its sequel by regular follow-up.

Adrenergic Receptors: ɑ Subtype
Adrenaline ≥ Noradrenaline >> Isoprenaline
α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase...
Adrenergic Receptors: β Subtype
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.
