A case of pathologic fracture of a mandibular condyle due to a primary adenocarcinoma of the rectum is presented. This is the first reported case of a secondary adenocarcinoma from the rectum to this site. Secondary metastases to the condyles are extremely rare. Only twelve have been reported in the literature. The primary tumor was from an unknown site in three cases (anaplastic adenocarcinoma); from the breast in four; and from the lung, liver, prostate, uterus, and hallux (a malignant melonama) in the remainder. Only of these tumors presented as a condylar fracture, and that was from a primary breast adenocarcinoma.
本文报告一例因直肠原发性腺癌导致下颌骨髁突病理性骨折的病例。这是首例报道的从直肠转移至该部位的继发性腺癌。髁突继发性转移极为罕见。文献中仅报道过12例。其中3例原发肿瘤部位不明（间变性腺癌）；4例来自乳腺；其余分别来自肺、肝、前列腺、子宫和拇趾（恶性黑色素瘤）。这些肿瘤中只有一例表现为髁突骨折，且该例源自原发性乳腺腺癌。
