Bilateral parotid gland metastasis as the initial presentation of a small cell lung carcinoma

Small cell (oat cell) lung carcinoma is a common neoplasm that represents 25% to 36% of all lung tumors. Metastatic extrathoracic sites are frequent, occurring in more than 95% of autopsy studies performed on patients succumbing to this disease. However, bilateral parotid metastases are rarely found. The following report describes such a case in which the diagnosis of lung carcinoma was made after recognition of the metastatic lesions.

Thyroid papillary carcinoma presenting as jaw and parotid gland metastases

A slowly progressing colloidal goiter of 20 years standing was excised in a 67-year old woman. Two years later, a metastatic tumor inducing facial swelling was diagnosed radiologically in the left parotid gland and left ascending mandibular ramus. The incisional biopsy confirmed papillary carcinoma of thyroid origin. The patient refused treatment. Six months later, she returned to the clinic and presented with advanced destructive changes of the involved structures. This rare case of unrestricted malignant growth may shed light upon the sequence and mode of metastatic invasion.
