    • Abstract

    Background
    Although primary neurogenic tumors of the lung are very rare, cellular schwannoma is a subtype of the classical schwannoma, which is a tumor of nerve sheath. Despite of pseudosarcomatous appearance, histopathologically, cellular schwannoma is considered as a benign tumor. However, it may carry atypical characteristics and risk of malign degeneration. We are presenting a case of primary pulmonary cellular schwannoma for discussing its clinical presentation and the prognosis.

    Methods
    A 65 years old male patient applied with the symptoms of cough and sputum production and found to have a 3x2.5 cm mass in the upper lobe of the right lung. At that time, retrospective examination of his available chest radiographs suggested a slowly growing lesion during a 4 years period. The mass was removed by extirpation and the histopathological diagnosis was cellular schwannoma. After surgical treatment no residuel lesion was detectable and he was doing well clinically.

    Results
    He had been followed up yearly for 5 years. Eight years after the operation a 3x3x4 cm mass was seen at the same site of the previous lesion but the patient refused any surgical or diagnostic intervention. During follow up the lesion was found to be 6x6x5 cm in diameters 12 years after the operation.

    Conclusion
    In cellular schwannoma the treatment of choice is surgical removal of the mass and the relapse of the disease is very rare. However, in this case the lesion seems to be the relapse of the previous disease. We suggest that in some cases extirpation of the mass may not suffice and surrounding tissue of close contact should also be removed to avoid relapses.
