Recurrent maxillary sinus cancer with only adrenal metastasis

Abstract

Abstract. Maxillary sinus cancer is rare, and often presents as a locally advanced disease. Recurrence commonly occurs locoregionally, while fewer patients present with distant metastasis; the most common sites involved are the lung and bone. This report discusses the case of a 64-year-old male who presented with a mass in the left submandibular area. Biopsy was performed and histological analysis identified a poorly differentiated squamous cell carcinoma. After staging work up, it was concluded the patient had a maxillary sinus squamous cell carcinoma at clinical stage IVA. The patient received a left partial maxillectomy and left radical neck dissection followed by postoperative chemoradiotherapy. After three months of CRT, the patient developed a left adrenal gland metastasis without locoregional failure. The patient subsequently received a laparoscopic left adrenalectomy and the results of histological analysis revealed a poorly-differentiated squamous cell carcinoma. Within one month of surgery, the patient had developed multiple metastases at the left adrenalectomy site and succumbed to the disease four months later.
