Cervical Schwannoma A Rare Cause of Tracheal Stenosis Misdiagnosed as Asthma

Cervical Schwannoma: A Rare Cause of Tracheal Stenosis Misdiagnosed as Asthma Layman Abstract : A rare condition called upper tracheal stenosis (narrowing of the windpipe) can sometimes be caused by a type of nerve tumor called a cervical schwannoma. However, because this is so uncommon, there is no standard treatment. In fact, no previous surgical cases have been reported in medical literature. This report describes a 48-year-old woman who was mistakenly treated for asthma for four years before doctors discovered that she actually had a tumor compressing her windpipe. A CT scan revealed the narrowing just below her vocal cords, and a biopsy confirmed it was a schwannoma, a usually non-cancerous tumor. Doctors considered surgery but decided on a conservative approach because the tumor had remained stable for seven years without growing or worsening the patient’s condition. She continues to be monitored annually to ensure the tumor does not increase in size. This case highlights the importance of correctly diagnosing breathing difficulties and suggests that careful monitoring, rather than immediate surgery, may be a safe treatment option for similar cases. _________ Original Abstract : Cases of upper tracheal stenosis due to cervical schwannoma are fairly rare, therefore, no treatment has been determined. Additionally, No surgical cases of upper tracheal stenosis caused by cervical schwannoma have been reported in the literature. This is a report of a case of cervical schwannoma with severe upper tracheal stenosis. In this case, a 48-year-old woman was treated with asthma for 4 years at another hospital, however, the patient was admitted to our hospital because of breathing difficulty. CT showed a tracheal stenosis lesion just below the vocal cords, and a biopsy revealed schwannoma. The tumour consisted of spindle-shaped cells, accompanied by collagen fibres, and no mitotic figures or atypia was observed; immunostaining revealed CD34 (-), S100 (+) and β-catenin (-), leading to the diagnosis of low-grade schwannoma. Regarding the treatment, conservative therapy is desired rather than tumor resection of the tumor by surgery, but the size of the tumor on the image and the patient’s condition have not been changed for 7 years. Once a year, conservative treatment is considered an option if the extratracheal tumor has not regrown.
