Authors present a case of epithelioid haemangiosarcoma of the thyroid gland in a 54-year-old female with a history of eufunctional nodular goitre. The patient was treated by total thyroidectomy with extirpation of cervical lymph nodes and by subsequent chemotherapy. The tumour behaved highly aggressively with early generalization and unusual way of metastatic spread into the wall of the stomach and duodenum. The patient died 3 months after the surgery due to therapeutically unmanageable bleeding into the GIT. The clinico-pathological aspects of the case are discussed.
