Superficial soft-tissue masses are among the most common indications for imaging of the extremities. A broad array of benign and malignant processes may be manifested in palpable cutaneous or subcutaneous masses or nodules. Because the imaging characteristics of many benign soft-tissue lesions overlap with those of malignant ones, knowledge of the patient’s clinical history (including any laboratory test results) and direct visual examination of the lesion often are important for differentiation. Histopathological analysis may be necessary to achieve a definitive diagnosis.
A 82 years old male was referred for investigation to our department of radiology with the complaints of superficial soft tissue mass in right scapular and shoulder region for past 8years. The patient underwent ultrasonogram , CT scan and MRI to assess the nature of the swelling and was diagnosed as myxoid variant of liposarcoma radiologically. The excision biopsy was reported as Epithelioid hemangioendothelioma, a rare superficial soft tissue vascular neoplasm. No previous reports of Epithelioid hemangioendothelioma occurring in right scapular and shoulder region superficially as soft tissue mass have been recorded in the literature so far.
