Upper Gastrointestinal Bleeding as a Manifestation of Metastasis from Laryngeal Cancer.

Upper gastrointestinal (GI) bleeding can be a rare manifestation of primary or metastatic tumor in the stomach. Tumors that commonly metastasize to stomach include breast, lung, and malignant melanoma. Laryngeal cancer usually metastasizes to the lung and cervical spine. We report the first case of upper GI bleed as a manifestation of laryngeal cancer in the stomach.

Introduction

Neoplasms of the upper gastrointestinal (GI) tract are an uncommon cause of upper GI bleed and account for less than 5% of all cases of severe upper GI bleeding.[1] There are many case reports of metastatic tumors in the stomach causing upper GI bleed as their initial presentation.[2,3] The tumors that metastasize in the stomach are most commonly lung, breast, and malignant melanoma.[4,5]

Case Report

A 75-year-old white man presented to the emergency room (ER) with complaints of nausea, vomiting, and lower back pain for 1 day. His past medical history included peptic ulcer disease, prostate cancer status post radical prostatectomy in 2007, recent abdominal aortic aneurysmal (AAA) repair, and stage IVa-Tx N2 M0 squamous cell laryngeal cancer diagnosed in July 2009 and treated with 3 failed rounds of combined chemoradiation. While in the ER, the patient developed bloody emesis and became lethargic. He was hypotensive, but otherwise normal on exam. Abdominal/pelvic computed tomography (CT) showed no leak or rupture of AAA, but showed an irregularly shaped 6.2 x 2.9-cm stomach mass along the left posterior wall of the gastric body, lesions in the splenic capsule, and a soft tissue mass posterior to the bladder and inferior to the rectum. Nasogastric tube aspirate was coffee ground in color. Laboratory tests showed hemoglobin 4.8 g/dL and white blood cell count 12.5 k/µL. Esophagogastroduodenoscopy confirmed a large friable mass in the gastric fundus (Figure 1). Biopsies revealed fragments of oxyntic-type gastric mucosa showing metastatic squamous carcinoma consistent with laryngeal cancer (Figure 2). The patient was resuscitated with 8 units of blood products and had no further bleeding, and was discharged with instructions to follow up for palliative radiotherapy.

Discussion

Typically, primary gastric cancers are adenocarcinoma, squamous cell carcinoma, lymphoma, or gastrointestinal stromal tumors. Adenocarcinoma is the most common type, constituting approximately 95% of all gastric cancers, followed by lymphomas (approximately 5%).[6,7] Primary squamous carcinoma of the stomach accounts for less than 0.7% of all primary gastric tumors, with a worldwide incidence of 0.04–0.07%.[8,9] Rarely, tumors in the stomach may be from distant metastases, most commonly from tumors of lung, breast, and malignant melanoma.[4,5] Typically, metastasis to the stomach presents as a solitary lesion, but can also present with multiple gastric lesions. These metastatic tumors can present with abdominal pain, nausea, vomiting, and bleeding.[5] Upper GI bleeding from stomach metastasis can present either as hematemesis or occult blood loss.[1,2] There are several case reports of hematemesis caused by stomach metastasis from renal cell cancer, lung cancer, and osteosarcoma.[2,10]

Laryngeal cancer usually presents as hoarseness, difficulty swallowing, or a lump in the neck. The most common site of metastasis in laryngeal squamous cell cancer is the lung, and cervical metastasis is most common in non-squamous cell laryngeal carcinoma.[11] There is only 1 case report in the literature in which metastasis from squamous cell laryngeal cancer was found in the stomach and presented as gastric perforation.[12] This is the first report of metastatic squamous cell laryngeal cancer to the stomach presenting as an upper GI bleed. This case is not only an unusual presentation of laryngeal cancer, but also highlights an exceedingly uncommon site for laryngeal metastasis and a rare cause of upper GI bleeding.
