Abstract
Solitary pulmonary plasmacytoma is extremely rare tumor therefore, we present clinical and surgical features of our case that is diagnosed postoperatively.
Fifty-year-old female patient was referred to our hospital for further examination since a lesionwas identified on chest radiograph during the preoperative investigations for gall bladder surgery. In radiological investigations, a homogeneous lesion, about 4cm diameter, contoured quite smooth, showing the central location was detected. There was not any intrabronchial pathology in performed fiberoptic bronchoscopy. Due to the localization of the lesion without the need for another diagnostic process, thoracotomy was performed for diagnosis and treatment. In exploration, a mass lesion with smooth margins, seated on major fissure that invades middle and lower lobe was detected. Frozen section of the mass was reported as a carcinoid tumor. Lower-middle bilobectomy and mediastinal lymph node dissection was performed since the tumor invades both lobes. It was reported that the tumor was Solitary Plasmacytoma and the lypmh nodes were reactive lymphadenitis in immunohistochemical studies on the pathological evaluation of tumor. The patient was discharged without any problem. Postoperative bone marrow biopsy was performed. The result was negative.
Solitary plasmacytoma manifesting as a solitary pulmonary tumor is very rare. For this reason, a full review is necessary to distinguish a systemic disease. In addition, over time, the majority of cases of pulmonary plasmacytoma can change into multiple myeloma must be considered and patients should be followed up closely.
