RESUMEN
INTRODUCTION: Metastases to the oral cavity are uncommon, accounting for only 1% of all oral malignant tumors. When they occur they mostly originate from primary tumors of the lungs, kidney, breast and prostate. Oral metastases from the primary colorectal carcinoma are much more infrequent. CASE OUTLINE: We present an unusual case of a 78-year-old man with a soft tissue oral metastasis originating from the primary colorectal carcinoma.The patient was referred to the Department of Otorhinolaryngology, Head and Neck Surgery with an intraoral mass on the right side of the maxilla. The diagnosis was confirmed by histopathologic examination and immunohistochemical analysis. CONCLUSION: Oral metastases occur rarely and often can mimic much more common benign lesions, therefore they should be considered as a possibility in a differential diagnosis.

Necrotizing fasciitis (NF) is an unusual, life threatening, rapidly advancing infection characterized by widespread fascial and subcutaneous tissue necrosis and gangrene of the skin. It most commonly affects the extremities, abdominal wall and perineum, whereas cervical NF is rare. NF of the head and neck is often caused by both aerobic and anaerobic microorganisms found in the upper aerodigestive tract. Usually, cervical NF originates from odontogenic, tonsillar and pharyngeal infection, and it is very rarely a complication of surgical procedure. Without immediate surgical treatment, cervical NF leads to mediastinitis and fatal sepsis. There is only one case of cervical NF after total laryngectomy described in the literature. We report two cases of cervical NF after total laryngectomy, selective neck dissection and primary vocal prosthesis insertion. In both cases, the infection spreads to thoracic region and in one of them NF was associated with Lemierre's syndrome, i.e., thrombosis of the internal jugular vein. In both patients, vocal prosthesis was inserted during the infection and did not influence the healing process.

The success of a frontal sinus endoscopic or external operation depends on the postoperative stenosis of the frontal sinus ostium. Formation of a stenosis can be prevented by placing a stent in the frontal sinus ostium. The period optimal for leaving the stent in the sinus ostium is yet to be established, but experts recommend a maximum six months period. This case report presents a female patient who underwent an endoscopic bilateral frontal sinus operation in 2005. Postoperatively, she developed a stenosis of the right frontal sinus recess which resulted in a series of reoperations. At the end of 2009, a Medtronix Xomed Incl Parell T-Frontal Stent was inserted by external approach. At the 21-month followup, the patient was still free from discomfort with the stent normally placed. Proper hygiene, regular monitoring and endoscopic cleansing of the patient's stent resulted in the sinus orderly functioning with the stent placed within its ostium, without incrustation or breathing difficulties and headaches as a consequence.

Eosinophilic granuloma is a rare, benign, lesion characterized by uncontrolled proliferation of Langerhan's cells. It is commonly found in a bone and has been described in almost every bone in the body. It usually affects children and is seldom found in adults. A case of 60-year-old adult male with an eosinophilic granuloma of the right temporal bone with infiltration of the temporal and infratemporal fossa and osteolysis of the squama of the temporal bone is presented. Diagnostic procedure and course of treatment are described. Controversies in the management and different approaches in therapy of such lesion are discussed because there is no agreed treatment protocol established.

Malignant tumours rarely metastasize to the oral cavity. When they do, such metastases may arise from various locations including the lung, breast, kidney, prostate and colon. Soft tissue oral metastasis from gastric adenocarcinoma is extremely rare, and limited information exists regarding the presentation and work-up of metastatic gastric carcinoma into the oral soft tissue. We present an unusual case of a 70-year-old man and review the records of 17 cases of soft tissue oral metastasis from gastric carcinoma in the English and Japanese literature. Metastatic lesions from all sources are typically diagnosed in patients in their fifth to seventh decade, with the most common sites of soft tissue metastasis being the gingiva and alveolar mucosa of the mandible. In almost one quarter of patients a metastatic lesion in the oral cavity is the first manifestation of an undiscovered primary malignancy. They grow rapidly and tend to bleed and ulcerate. Because of their rarity and clinical characteristics, gastric metastatic tumours in the oral cavity are challenging to diagnose. Inflammatory and reactive lesions are common in the oral cavity and they should be considered in the differential diagnosis. Careful examination with a high degree of clinical suspicion, as well as a multidisciplinary approach is suggested.
