Blog Article

Human pulmonary dirofilariasis (HPD) is a rare zoonotic infection caused by Dirofilaria immitis.Dogs are the definite hosts and humans are infected occasionally via a vector, generally a mosquito.Most thoracic neurilemmoma arise in the mediastinum and fewer tumors originate peripherally from the intercostal nerves.Most patients with HPD or thoracic neurilemmoma are asymptomatic and these diseases nutrafin betta enviro-clean how to use are often discovered incidentally.We present a 53-year-old female who was found to have a pulmonary nodule and a chest wall nodule during a routine health examination.

She underwent a video-assisted thoracoscopic surgery (VATS) with partial lung resection and local excision of the chest wall.The pathological examination revealed a coiled, degenerating Dirofilariasis immitis worm tenga air-tech regular surrounded by granulomatous inflammation with caseous necrosis and a neurilemmoma composed of S-100 protein immunoreactive but smooth muscle actin negative spindle cells.Because these diseases are self-limiting and make further treatment unnecessary, video-assisted thoracoscopic surgery (VATS) is considered preferable and less invasive for definitive diagnosis and management.
