Etiological factors, stages, and the role of the foreign body in foreign body tumorigenesis: a review.
Attempts were made to analyze the process of foreign body (FB) tumorigenesis and to identify etiologically significant factors by correlating information in the literature and recent experimental data from our labroatory. It appears that the process of FB tumorigenesis is dependent on sequence of specific conditions as expressed by the following criteria: (a) cellular proliferation and tissue infiltration during acute FB reaction; (b) fibrosis of the tissue capsule surrounding the FB; (c) quiescence of the tissue reaction, i. e., dormancy and phagocytic inactivity of FB-attached macrophages; and (d) availability of a FB surface for direct contact with clonal preneoplastic cells. There is no indication that the initial acquisition of neoplastic potential and the determination of specific tumor characteristics are based on direct physical or chemical reaction between cells and the FB. These etiological key events occur presumably in mesenchymal stem cells associated with the microvasculature no later than during the acute stage of FB reaction and certainly long before clonal descendants of these cells are first found in contact with the FB surface. In fact, there is no reason to assume that cells with neoplastic determination may be present in normal tissue prior to the introduction of a FB and that the FB would only create the conditions required for stepwise preneoplastic maturation.

Foreign bodies.
Foreign bodies are uncommon, but they are important and interesting. Foreign bodies may be ingested, inserted into a body cavity, or deposited into the body by a traumatic or iatrogenic injury. Most ingested foreign bodies pass through the gastrointestinal tract without a problem. Most foreign bodies inserted into a body cavity cause only minor mucosal injury. However, ingested or inserted foreign bodies may cause bowel obstruction or perforation; lead to severe hemorrhage, abscess formation, or septicemia; or undergo distant embolization. Motor vehicle accidents and bullet wounds are common causes of traumatic foreign bodies. Metallic objects, except aluminum, are opaque, and most animal bones and all glass foreign bodies are opaque on radiographs. Most plastic and wooden foreign bodies (cactus thorns, splinters) and most fish bones are not opaque on radiographs. All patients should be thoroughly screened for foreign bodies before undergoing a magnetic resonance imaging study.

Esophageal foreign bodies.
Foreign body ingestion is a common occurrence in children and in specific high-risk groups of adults such as those with underlying esophageal disease, prisoners, the mentally retarded, and those with psychiatric illnesses. Although most foreign bodies pass through the gastrointestinal tract without difficulty, sharp, pointed, and elongated foreign bodies are associated with a greater risk of perforation, vascular penetration, and other complications. Foreign body ingestion is usually diagnosed based on a history of ingestion given by the patient or an observer. However, children and impaired adults may be unable to give an accurate history, and a high index of suspicion must be maintained in these groups. Dysphagia and odynophagia are the usual symptoms of foreign body impaction in the esophagus. Respiratory symptoms due to compression of the adjacent trachea are also common in younger children and are occasionally the presenting symptom in adults. The preferred method of removal of esophageal foreign bodies is extraction with the flexible endoscope. This may be accomplished in both adults and children with the use of conscious sedation rather than general anesthesia. The availability of grasping instruments specifically designed for foreign body removal and snares greatly facilitates endoscopic extraction. An overtube conveys all of the advantages of the rigid esophagoscope to the flexible endoscope, enabling extraction of sharp and pointed foreign bodies while protecting the mucosa from injury. Adherence to the general principles of foreign body removal and proper preparation result in successful removal rates as high as 98%, with minimal or no complications. Nonendoscopic methods of removal are associated with increased risks of perforation and aspiration and generally should be avoided, with the exception of a trial of intravenous glucagon. Surgical removal is rarely indicated except in the event of perforation or other foreign body complications.

Management of subglottic foreign bodies.
Foreign body aspiration is not an infrequent encounter in the practice of otolaryngology and requires immediate attention. The vast majority of foreign body aspirations occur in children less than 3 years of age, and the actual event of aspiration is frequently not witnessed. Although inhaled foreign bodies most often lodge in the bronchi, laryngotracheal foreign bodies also occur and are potentially more dangerous. Specifically, subglottic foreign bodies present unique clinical challenges. The diagnosis of subglottic foreign bodies is often difficult and they are commonly confused with other causes of upper airway obstruction. We present our experience with the diagnosis and management of seven patients with subglottic foreign bodies, who presented with an abnormal airway and whose problems were initially misdiagnosed. The radiographic and clinical features are discussed with a review of our surgical management.

The role of CT imaging in the evaluation of cervical esophageal foreign bodies.
Foreign bodies in the hypopharynx and cervical esophagus, such as chicken and fish bones, occur frequently and usually need radiologic work-up in order to demonstrate the presence of the foreign body and its location. Plain antero-posterior and lateral X-ray views of the neck, and if needed, a barium swallow, are the standard. When these studies fail to show the foreign body, unenhanced CT may demonstrate these small calcified esophageal foreign bodies. We evaluated 13 patients with cervical esophageal foreign bodies by CT. It is readily available and rapid and exposes the patient to less radiation than a barium swallow. CT evaluation with soft tissue and bone windows may replace the barium swallow because of its better detection of thin, small, minimally calcified foreign bodies which are often obscured by overlying tissues in the usual X-ray studies.

Soft tissue foreign bodies.
Foreign bodies embedded in soft tissue can cause toxic and allergic reactions, inflammation, or infection, but the severity of these complications varies widely. Removal can be difficult and time consuming, and the potential damage to tissues caused by the procedure must be weighed against the risk posed by a particular foreign body. Plain and mammographic radiography, xeroradiography, computed tomography, and ultrasonography can be used to detect foreign bodies suspected during clinical evaluation. The exact position of an object buried in soft tissue is difficult to determine using two-dimensional imaging techniques. Surface markers, multiple-projection radiographs, wire grids, fluoroscopy, or stereotaxic devices may help to locate it. Not all foreign bodies are discovered during the initial patient encounter; several signs reveal the presence of a retained foreign body in a wound.

Hypopharyngeal and oesophageal foreign bodies.
Foreign bodies in the food passages are quite common in Jos Community. Majority of 119 cases seen over a period of four years were children 92.4% and a coin was the commonest foreign body (86.5%). The site of lodgement of the foreign body was hypopharynx and abdomen in 11 cases each while 97 were held in oesophagus, mainly in its upper part. Removal of the foreign body by oesophagoscopy was difficult in patients who presented late. The coins formed a pouch in posterior oesophageal wall in six cases while their anterior surfaces got discoloured in 14 cases causing difficulty in their identification. Besides coins in children and dentures in adults, nine patients accidently swallowed a wide variety of foreign objects of different shapes and sizes. Management of such cases has been discussed.

Rectovulvar fistula in a child secondary to an unusual foreign body.
Foreign bodies in the female genital tract are well recognized as a cause of pain, discharge, secretions, and infection. In the small child, the presence of a vaginal discharge is usually associated with either a common object which has been inserted or sexual abuse complicated by a sexually transmitted disease. A 3-year-old child presented with a recurrent labial secretion and drainage due to an unusual foreign body. It was only during a second operation that the possibility of a foreign body was entertained, and diagnostic testing was begun. A third operation permitted removal of the foreign body, a large bone probably of animal origin. The fistula tract was closed after a colostomy was performed. This represents the first reported case of a rectovulvar fistula not of a congenital nature.

Infected granuloma and inclusion cyst secondary to a retained foreign body.
Foreign body granuloma formation and epidermal inclusion cyst formation are a common result of retained foreign bodies. The subsequent rupture of an inclusion cyst will result in abscess formation along with ulceration. The following is a review of pathology involved in granuloma formation, as well as a presentation of an interesting case involving granuloma formation secondary to a retained foreign body.

Unusual complication of ingestion of a foreign body.
Foreign bodies of the upper aerodigestive tract are common problems dealt with by the otolaryngologist. Among all foreign bodies in the oesophagus, an open safety pin still presents a challenge for the ENT specialists because of its propensity to pierce the oesophagus and surrounding structures. We present an interesting case of a long-standing foreign body i.e. an open safety pin, which, after piercing the hypopharynx, caused fatal common carotid artery rupture.

Progressive ulnar neuropathy caused by delayed migration of a foreign body.
Foreign bodies in the hand can cause a variable degree of acute or delayed injuries to the important structures. We report a rare case of a progressive ulnar neuropathy caused by delayed migration of a foreign body in the forearm. Ultrasonographic localisation and surgical removal of the foreign body resulted in gradual recovery of neurological function.

The combined use of a Fogarty balloon with extraction forceps for the controlled retrieval of an endobronchial foreign body.
Foreign body aspiration is a common problem in children necessitating prompt recognition and early treatment to minimize the potentially serious and sometimes even fatal consequences. We report the case of a 7 year old girl with a peanut lodged in her right main bronchus. Bronchoscopy identified the foreign body which was then removed by the combined use of a Fogarty balloon catheter and extraction forceps. This case differs from previous reports, in that the foreign body and forceps were removed separately from the balloon catheter, which theoretically should minimize the risks associated with this procedure.

The two-headed stethoscope: its use for ruling out airway foreign bodies.
Foreign body aspiration is a common concern for physicians and surgeons who care for children. Evaluating infants and toddlers to rule out this possible diagnosis is often fraught with difficulties. Specifically, the standard stethoscope is of limited use unless unilateral asymmetry of breath sounds can be appreciated. Inspiratory and expiratory chest X-rays in children often appear to show a very similar diaphragmatic excursion and, unless the object is radiodense, the determination of foreign body aspiration is frequently not possible. Other procedures, such as flexible or rigid endoscopy, are more invasive and are reserved for children with positive findings or a less acute but more perplexing scenario. We present the use of the two-headed stethoscope as an option for evaluation of children to rule out foreign body aspiration. Our experience with this instrument over the past 10 years has consistently allowed us to non-invasively differentiate the presence or absence of objects in the airway.

Ingestion and aspiration of foreign bodies.
Foreign bodies may be swallowed as well as aspirated, but patients and their relatives may not understand the distinction. Fortunately, swallowing occurs more often than aspiration. Dental prostheses present specific problems in this regard. Their configuration impedes easy gliding through the esophagus and makes their extraction difficult. Swallowing of foreign bodies in elder patients is often explained by a decrease in psychological or neurological function, which undoubtedly may occur. The loss of tactile sense of the hard and soft palate as a result of complete denture use is another reason for frequent occurrence of this problem in elder patients.
