Case 1 A 64-year-old man visited our clinic complaining of an asymptomatic nodule on his right thigh, detected 10 days previously. Physical examination revealed a solitary subcutaneous nodule, 1.5 cm in diameter on his right thigh. Twenty years previously the patient had undergone surgery to remove a "worm" from his leg. The patient stated that he enjoyed eating raw snakes. On performing excisional biopsy of the lesion, the white, flat, shiny sparganum was detected and removed (Fig. la). The histopathological study of the biopsy specimen showed several encapsulated, mummified sparganum pieces and dense lymphohistiocytic infiltration along with neutrophils and eosinophils (Fig. lb). Case 2 A 53-year-old woman was noted to have an asymptomatic nodule on her inguinal area for over 3 years. Although the lesion was asymptomatic the patient dubiously described the lesion as creeping upward in a linear pattern at negligible speed. The patient denied ingesting snakes or any kind of exotic food, yet admitted to drinking from springs occasionally as she climbed mountains. On physical examination, a relatively ill-defined soft nodule was detected on her left inguinal area. While performing excisional biopsy of the lesion, an 8 cm sized white, flat sparganum was noticed and removed (Fig, 2). The histopathological study revealed a panniculitis infiltrated with eosinophil and lymphohistiocytes. Case 3 A 41-year-old man presented with an asymptomatic nodule on his right thigh detected 3 years previously. The patient had eaten raw snakes about 10 years earlier. The clinical feature of the lesion was a solitary pea-sized nodule without any change in color on overlying skin, The biopsy from the lesion disclosed fragments of a larval cestode with morphologic features of sparganum (Fig. 3).
