“…Several studies have recommended palliative treatment (e.g., surgical treatment, chemotherapy, and radiotherapy) to improve the quality of life (QOL) and to maintain the patient's comfort 7,8 . We found 54 cases of oral metastasis of PCs that were reported from 1991 to 2021 in PubMed and Google scholar 9–45 and reviewed these cases, including our case. Kaplan‐Meier survival analyses were performed to determine whether palliative treatment affected overall survival.…”

Background: Metastases of pulmonary adenocarcinomas (pADCs) into the oral cavity are rare and sometimes misdiagnosed because of clinical findings that are similar to benign or inflammatory lesions.Case presentation: A 79-year-old man had a soft elastic mass in the oral cavity.Cytological and histological examinations revealed a metastasis of a pADC that was vimentin-positive. Conclusion:Oral cytology may be valuable for the detection of metastatic lesions in the oral cavity. Palliative surgery for maintaining the oral function may be beneficial to improve quality of life, and it did not affect survival time in Kaplan-Meier analysis from the literature review.

“…3-5 Among the metastatic tumors in the gingiva, gastric cancer as a primary source was exceedingly rare, amounting to only a few sporadic case reports in the English and Japanese literature (Table 1). [6][7][8][9][10][11][12][13][14] From another point of view, gastric cancer quite rarely metastasizes to the oral region. Abrams et al 17 reviewed 119 autopsy cases of gastric cancer and demonstrated that the liver, lung and peritoneum were frequent distant metastatic sites.…”

“…A subsequent recent review of 547 metastatic malignancies in the oral region has also confirmed the order of frequencies of primary sources, in which gastric cancer was found in only 10 cases 5 . Furthermore, metastasis to the oral soft tissue is less common than that to osseus tissue; thus, incidences of gastric cancer metastasizing to the oral soft tissue were far rarer, with only a few sporadic cases reported in the literature 6–15 . The rarity of gastric cancer involving the oral region, the osseus and soft tissue, becomes particularly apparent when the small number of reported cases of such metastasis are compared with the thousands of reports of metastases to other parts of the body such as the liver, lung and peritoneum.…”

The present case report describes a gastric cancer which showed unusual metastasis in the oral region. A 56-year-old male patient underwent total gastrectomy and splenectomy due to advanced gastric cancer in the upper third of the stomach. Fifteen months later, he presented with anorexia and gingival swelling of durations of approximately 3 and 1 month, respectively. The gastric tumor was histologically a signet ring cell and a poorly differentiated cancer with a moderate degree of vascular invasion. Biopsy specimens from the gingival tumor revealed a signet ring cell cancer. Other metastatic sites were the brain, limb bones and abdominal lymph nodes. A bone scintigram revealed an abnormal uptake in the limb bones, while it did not exhibit any abnormality in the oral region. Correlation between the histology of the gingival tumor with that of the gastric cancer, as well as the absence of a gingival tumor at the time of prior gastrectomy, led to a diagnosis that the gingival tumor was a metastasis from gastric cancer. Gastric cancer metastasizing to the oral region, either the osseus or the oral soft tissue, is very rare. Although it cannot be proved without an autopsy, negative findings in the mandible by bone scanning in the present case suggest that direct gingival metastasis can be considered, rather than mandibular metastasis involving the gingiva. Hematogenous spread could be a mechanism of metastasis for this unusual tumor.
