The Case Report of the Pulmonary Larval Paragonimiasis with Simulating Cancer of the Lung

Larval Paragonimiasis is a parasitic disease caused by the larvae of the pulmonary fluke. In contrast to the classical Paragonimiasis, larval occurs with a large number of clinical manifestations. However, this fact only complicates the diagnosis of larval Paragonimiasis, as the abundance of clinical manifestations leads to false diagnosis of other diseases. Another distinguishing feature of this form of Paragonimiasis is the propensity to generalization and to imitation of a clinical picture of malignant neoplasms. A 66-year-old patient was infected with a larval form of Paragonimiasis, with invaded lung, pleura, heart, liver, right kidney, spleen, stomach and small omentum. Diagnostic measures performed could not give an accurate idea of ​​the nature of the disease, so a diagnostic thoracoscopy was performed and urgent biopsy from region of dissemination was taken, which showed a glandular cancer of the lower lobe of the lung. This circumstance became the reason for performing atypical resection of the affected part, which was done, but on the second day of the postoperative period the patient died as a result of Pulmonary Embolism (PE). The cause of the disease is chronic pulmonary generalized Paragonimiasis (cyst and pneumosclerotic stages) with neoplastic syndrome.
