Primary Pleural Schwannoma as Incidental Findings: An Unusual Case Report

Abstract

Schwannomas are neurogenic, benign, slow growing tumours that originate in Schwann's intersecting fascicles of the peripheral nerves. This article reports the case of a previously healthy 51-year-old male, where a 9.0x6.5 cm (3.5x2.5 in) sized pleural mass was found after the patient presented a haemoglobin level of 3.2 g/dL in a blood smear at a routine check-up. The patient had no relevant medical, family, or psychosocial history and presented no relevant symptoms. After diagnosing and treating a chronic haemorrhoidal disease, the tumour was removed and studied. Demonstrating histopathological and immunohistochemical features of schwannoma, its uniqueness and rarity after successful management of the disease contributes to the medical literature as a histopathologic diagnostic standard and a therapeutic option for future cases of pleural schwannoma. Sharing the histopathologic features of schwannoma is not common, usually, the available case reports are lacking. The patient was able to recover fully and had no significant or severe complications associated with medical care.
