Anterior tongue metastasis from lung cancer

Squamous cell lung carcinoma with gastrointestinal metastasis: a case report and review of literature

Squamous cell lung carcinoma (LUSC) originates from squamous cells and has a high rate of metastasis and recurrence. The lack of effective genetic targets and specific therapies has resulted in a poor prognosis for patients with LUSC. Gastrointestinal metastasis of LUSC is a rare occurrence in clinical practice. Patients with gastrointestinal metastasis usually have worse overall survival and the process of diagnosis is more complicated than those with metastasis elsewhere. What's more, there are no helpful guidelines for treating patients with a clinically confirmed diagnosis of gastrointestinal metastasis, which means the treatment method is limited. Here, we review the clinical features, diagnosis, and treatment of LUSC patients with gastrointestinal metastasis and report a rare case of LUSC accompanied by gastrointestinal metastasis. The patient was admitted to the hospital with coughing and hemoptysis. A tumor was found in his lung, and lesions were initially controlled with standard treatment. The patient's tumor re-occurred again shortly for which treatment was lacking. Without effective treatment methods, the disease was difficult to control. Our learnings from the case demonstrate that LUSC metastasizes to secondary lymphoid organs of the gastrointestinal tract, usually with a poor prognosis.

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.

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

RATIONALE

Tongue metastasis from lung cancer is extremely rare, and the prognosis of these patients is rather poor.

PATIENT CONCERS

A 56-year-old man was found a 4-cm cavity lesion in the left upper lobe, which was initially misdiagnosed as tuberculosis.

DIAGNOSES

A case of lung squamous cell carcinoma that metastasized to the base of a patient's tongue.

INTERVATIONS

We send the biopsy of the lung and the tongue lesions for gene sequencing.

OUTCOMES

He received systemic chemotherapy, but continued to have pain at the base of his tongue and died 7 months later.

LESSONS

From sequencing data, mutations in KRAS proto-oncogene, GTPase (KRAS), phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA), and tumor protein p53 (TP53) were found in the tumor biopsy of the patient. All of these were indicators of poor prognosis.

Primary colonic-type adenocarcinoma of the base of the tongue: a previously unreported phenotype

Primary lingual adenocarcinomas are rare and typically of salivary or seromucinous glands origin. Similarly, metastatic adenocarcinoma from distant primary sites to the tongue is an uncommon event, with only 3 cases from a colonic primary site reported. We present, for the first time, 2 primary colonic-type adenocarcinomas of the base of the tongue and discuss their putative origin and the clinicopathologic characteristics.
