Case 193. Cysticercosis of skin (42 y-o F)
Excised subcutaneous cystic nodule in the hip
Key words : Cysticercus cellulosae, Taenia solium, cysticercosis
A solitary cystic lesion with white-colored, solid mural nodules is presented (gross findings). The human can be not only the final host of Taenia solium but also the paratenic host of Cysticercus cellulosae (the name of the second stage larva).   Gross appearance of the cyst-lining component of Cysticercus cellulosae in the subcutis. The patient has eaten a cysticercus in the pig meat. Compare with multifocal neurocysticercosis (case 130), in which vegetable (Korean kimchi) contaminated with fertile ova was ingested by the patient.
Histologically, the body wall consists of microvillous tegument and myxoid matrix, in which vesicles and calcified bodies are observed (HE).   In the largest white mural nodule, a protoscolex with paired suckers is identified (HE). Hooklets are not seen in this section. This makes the differential point from Sparganum mansoni.
