Abstract

Background
In malignancies‘ detection of metastatic foci is of value in making therapeutic plans for treatment of disease and prevention of life-threatening complications. Common sites for metastasis of bronchogenic cancer include lymph nodes, li ver, brain, adrenals and bone. Skull, vertebrae, ribs and long bones are common sites for bone metastasis. But in epidermoid carcinoma, the incidence of bone metastasis is relativel y low and especially to the distal phalangeal bone is rare
Methods
We experienced a case of epidermoid carcinoma with the first distant metastasis to the fifth distal phalangeal bone, right toe
Results
The initial stage in the diagnosis of epidermoid carcinoma was T4N3MO. During the third round of anticancer chemotherapy, we recognized the distant metastasis to the fifth distal phalangeal bone for the first time. Localized abnormal findings were noted by bone X-ray and scanning. By a histopathologic examination of the amputated t oe, we confirmed the metastasis of epidrmoid bronchogenic carcinoma
Conclusion
If localized abnormal finding is discovered at an unusual site for metastasis, we recommend physicians to consider the possibility of metastasis even though it is very low.
