Abstract:
Ectopic paragonimiasis is found in many organs, such as the mesentery, liver, spleen, peritoneum, omentum and central nervous system. However, thyroid gland involvement is quite rare. A 55 year old woman was admitted to our hospital on account of a painless anterior neck mass. A ultrasonographic examination showed ill-defined, hypoechoic nodule with calcification in the right lobe of the thyroid gland. A right lobectomy was performed after a fine needle aspiration biopsy showed there were no malignant cells histologically. The histological diagnosis was a foreign body granuloma with multiple ova of Paragonimus in the thyroid gland. Postoperatively, the immunoserologic test for Paragonimus westermani was positive it. A diagnosis of this rare clinical entity before a surgical excision and histopathology examination is unlikely. Therefore an ectopic paragonimiasis of the thyoid gland should be considered when making a differential diagnosis of thyroid masses. We present a case of ectopic paragonimiasis, which presented as a thyroid nodule with a review of the relevant literatures.
