Palpable axilla mass in woman is relatively rare. Almost all palpable lumps in axilla are axillarys accessory breasts without mass lesion. All diseases develop in breast can also develop in axillarys accessory breasts and other soft tissue mass can occur in axilla. Malignant fibrous histiocytoma (MFH) is the most common malignant soft tissue tumor, but axillarys MFH is extremely rare. We report our experience with a 75-year-old woman with MFH in axilla, treated with wide excision.

We report the case of a giant cell tumor with diffuse interstitial hemorrhaging and unusually prominent cystic components in the soft tissue of the thigh which has not been reported previously. Magnetic resonance image (MRI), showed signal intensity typical of a giant cell tumor. However, because of its conspicuous large well-circumscribed cystic components, the differential diagnoses, based on the image findings from an ultrasonography (US) and MRI, were complicated epidermoid cyst, cystic change of a neurogenic tumor, and a parasitic cyst.
