Hydatid cyst of the foot: a case report

BACKGROUND: Hydatid cyst is rarely located in soft tissues. This case of a hydatid cyst over the plantar surface of our patient's foot is one of the rarest presentations. CASE PRESENTATION: This is a case report of a 22-year-old Somali who presented with a lump over the plantar surface of his foot of 1-year duration. The diagnosis of hydatid cyst was made intraoperatively from the typical appearance of a hydatid cyst. The cyst was completely excised. No local recurrence has been detected to date. CONCLUSIONS: The rare location and uncommon incidence made the initial diagnosis of hydatid cyst of the foot difficult. Detection of the typical germinal membrane can guide the diagnosis of hydatid cyst in rare locations that are found incidentally.
