Cutaneous Gnathostomiasis: A Case Report from Thailand
Abstract
Gnathostomiasis is transmitted to humans via ingestion of third-stage larva of genus Gnathostoma. Thailand is considered an endemic area for the disease. We reported a 65-year-old Thai male patient with clinical presentation of a small number of nodular migratory swellings on the face and neck. The histopathology of skin biopsy revealed parasitic material surrounded by eosinophil infiltration and fibrosis in deep dermis. Therefore, we were able to confirm diagnosis of cutaneous gnathostomiasis. After treatment with ivermectin followed by albendazole, the lesions still persisted; thus, surgical excision of lesions may be the necessary curative treatment.
