Metastasis to the finger of oral floor squamous cell carcinoma: A case report

When cetuximab is used, diagnosing finger metastasis can be difficult due to the side effects of paronychia and color changes of nails. Finger metastasis may be a marker of multiple metastasis; therefore, it can lead to a poor prognosis

A case of intraosseous spindle cell carcinoma of the mandible

Spindle cell carcinoma is a unique and rare biphasic tumor consisting of a squamous cell carcinoma component and a sarcomatoid component of spindle cells. We report a rare case of spindle cell carcinoma of the mandible that was considered an intraosseous carcinoma. The patient was a 67-year-old woman with a chief complaint of paresthesia of the left lower lip. There was no particular sign of the left mandibular gingiva. A panoramic radiograph showed a radiolucent area in the left premolar region of the mandible. Computed tomographic scans showed a ring-enhanced mass lesion in the same location. A biopsy was performed for a diagnosis of mandibular osteomyelitis. Because the diagnosis was granulation tissue, we performed curettage of the mandibular bone. However, the surgical specimen was histopathologically and immunohistochemically diagnosed as spindle cell carcinoma. We performed a segmental mandibulectomy with a safety margin. There has been no sign of local recurrence or metastasis during a follow-up period of 1 year 9 months.川嵜 康大, 松岡 裕大, 西野 仁, 平岡 慎一郎, 磯村 恵美子, 浜口 裕弘, 下顎に発生した顎骨中心性紡錘細胞癌の1例, 日本口腔外科学会雑誌, 2014, 60 巻, 3 号, p. 127-131, 公開日 2015/05/19, Online ISSN 2186-1579, Print ISSN 0021-5163, https://doi.org/10.5794/jjoms.60.127
