　We encountered two rare cases of soft tissue tumor arising in the deep neck. The first case was a 29-year-old woman diagnosed as having pseudomalignant osseous tumor. At surgery, a circumscribed, hard mass was found in the deep portion and adhered to the cervical vertebra. The mass was extirpated together with a layer of the surrounding macroscopically intact tissue. The post-operative course was uneventful. The second case was a 59-year-old man diagnosed as having epithelioid sarcoma. At surgery, a circumscribed, invasive mass was found in the deep portion and adhered to the cervical vertebra. The mass was excised together with adjacent muscle tissue and fat tissue. The post-operative course was uneventful. Immunohistochemical evidence in these cases are also presented.

Key words :soft tissue tumor, deep neck, pseudomalignant osseous tumor, epithelioid sarcoma
