Epidermoid cyst of the spleen: a clinico-pathologic correlation.

A large epidermoid cyst of the spleen in a 39-year-old woman is reported. Diagnosis and treatment are discussed. Epidermoid cysts of the spleen occur in newborns, children and adults up to 50 years of age, with the peak incidence in the second and third decades. Abdominal mass, discomfort and non-specific gastrointestinal complaints are most common clinical presentations. Radionuclide imaging, computed tomography and sonography are the preferred preoperative noninvasive diagnostic methods.
