Two cases of primary intraosseous squamous carcinoma (PIOSC) are reported. One PIOSC is in the mandible of a 24-year-old man and appears to be a keratinizing PIOSC arising de novo. The other PIOSC presented in the edentulous maxilla of a 56-year-old man and was diagnosed as a PIOSC arising from an odontogenic cyst. The 2nd tumor subsequently metastasized to a cervical lymph node. Previous reports have noted a favorable prognosis for PIOC arising in odontogenic cysts, and only 3 other instances of metastases of a PIOSC in an odontogenic cyst have been documented.
报告了两例原发性骨内鳞状细胞癌（PIOSC）。一例PIOSC发生于一名24岁男性的下颌骨，似乎是一例原发性角化性PIOSC。另一例PIOSC发生于一名56岁男性的无牙上颌骨，被诊断为由牙源性囊肿发生的PIOSC。第二例肿瘤随后转移至颈部淋巴结。既往报道指出，起源于牙源性囊肿的PIOC预后良好，且仅有另外3例牙源性囊肿内PIOSC转移的病例被记录。
