Disseminated Langerhan's cell histiocytosis: a case report and review of the literature.

Langerhan's cell histiocytosis is characterized by the presence of large mononucleated cells associated with inflammatory cells. We describe the clinical presentation, histopathology and some immunohistochemistry findings, in an eight-year-old female patient.

Human dicrocoeliasis presenting as a subcutaneous mass.

Human infection by Dicrocoelium dendriticum, a zoonotic liver fluke, is uncommon and soft tissue manifestation is extremely rare. The infection has no specific clinical signs or symptoms and diagnosis may be missed completely, thus treatment may be delayed. Diagnosis in humans is by identification of the eggs in the stool, while a living or dead fluke is rarely seen.
