A case report of tongue metastasis from lung squamous cell carcinoma and literature review

Unusual tongue metastasis from lung adenocarcinoma in a cat with feline lung-digit syndrome

This report describes the pathological findings in a 15-year-old spayed female Domestic Shorthaired cat with a pulmonary adenocarcinoma characterized by feline lung-digit syndrome (FLDS) and unusual tongue metastasis. Felis catus papillomavirus type 3 (FcaPV-3) DNA was amplified from the lingual sample but not from samples of the pulmonary mass or digital or splenic metastatic lesions, indicating the presence of FcaPV-3 in the oral cavity but not suggesting a role for FcaPVs in tumour pathogenesis. FLDS is a clinical entity in which primary lung tumours present because of metastatic digital lesions. In humans, tongue metastasis may be a rare initial presentation of lung cancer, whereas, to the best of our knowledge, tongue metastasis of feline tumours has not been reported. Although lingual metastases are rare, the present findings serve to remind clinicians that metastatic manifestations of primary lung tumours in cats may involve multiple extrapulmonary sites, including the tongue.

Tongue metastasis originated from esophageal squamous cell carcinoma: A case report

The tongue is a rare site for metastasis. In this report, we present a woman with a history of esophageal squamous cell carcinoma who suffered from two metastatic masses on the left side of her tongue 2 years after completion of definitive chemoradiation. The patient underwent chemotherapy and left hemi‐glossectomy.

Tongue swelling as a manifestation of tongue metastasis from pulmonary sarcomatoid carcinoma: A case report

BACKGROUND

Sarcomatoid carcinoma is a rare subtype of non-small-cell lung cancer, commonly associated with locally advanced disease, early metastasis, and poor prognosis. Tongue metastasis from lung cancer is a rare condition that may occur in advanced stage of the disease.

CASE SUMMARY

The patient was a 70-year-old female with a history of resected pulmonary sarcomatoid carcinoma (PSC) who presented with subacute tongue swelling, imparting the clinical impression of a lingual abscess. However, histologic examination of the partial glossectomy revealed a high-grade, poorly differentiated spindle and epithelioid carcinoma consistent with metastatic PSC.

CONCLUSION

Although uncommon, clinicians should be cognizant of the possibility of a metastatic process to the tongue mimicking a benign or inflammatory process. A high index of suspicion for metastatic disease should be maintained when tongue swelling is observed in patients with a known history of PSC.
