1/18. Paravertebral and diaphragmatic mass: an ectopic location of bronchogenic cyst.Bronchogenic cysts constitute one area of the broad spectrum of developmental anomalies of the primitive foregut. They arise from anomalous budding of the primitive tracheobronchial tube and are commonly located in the mediastinum or the lung parenchyma, closely related to the tracheobronchial tree. In rare cases, they can migrate to subpleural, pericardial, paravertebral and cervical locations, if embryological connections with their parent bronchus are lost. Plain chest radiography and computed tomography have been the primary imaging modalities used for diagnosis. Computed tomography is frequently associated with misleading information with respect to the cyst density. magnetic resonance imaging has been shown to be useful in the differential diagnosis of cystic mediastinal masses. We present a patient with two asymptomatic bronchogenic cysts found at a distance from the tracheobronchial tree.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
2/18. The multiple facets of pulmonary sequestration.PURPOSE: The goal of this study was to identify the proportion of sequestrations that were atypical or associated with other entities, such as congenital cystic adenomatoid malformations, communicating bronchopulmonary foregut malformations, bronchogenic cyst, and scimitar syndrome. methods: All charts of patients with pulmonary sequestration admitted at 2 children's hospitals from 1982 to July 1999 were reviewed retrospectively. The authors included all anomalies with a systemic arterial supply or without bronchial connection. RESULTS: Only 22 of the 39 patients (56%) had a classic isolated extralobar or intralobar sequestration, whereas the others presented with a spectrum of anomalies. Of the 13 cases diagnosed prenatally, 85% were asymptomatic at birth. In contrast, 26 cases diagnosed postnatally were all symptomatic, with those patients less than 2 weeks old presenting with various degrees of respiratory distress, and those older than 2 weeks old presenting with respiratory infections. The correct diagnosis was made preoperatively in 59% of cases. Only 4 patients did not undergo resection of their lesion, of which, 1 underwent interventional radiology with embolization of the anomalous arterial supply. Follow-up issues of importance included pneumonia, asthma, gastroesophageal reflux, and pectus excavatum. CONCLUSIONS: Sequestrations represent a spectrum of anomalies that overlap with other lung lesions. To facilitate management, they should be described according to their (1) connection to the tracheobronchial tree, (2) visceral pleura, (3) arterial supply, (4) venous drainage, (5) foregut communication, (6) histology, (7) mixed/multiple lesions, and (8) whether there are associated anomalies. Surgeons should be aware that approximately 50% of sequestrations could be atypical or associated with other anomalies. This should be kept in mind when weighing the benefits of resection versus conservative management of pulmonary sequestrations.- - - - - - - - - - ranking = 0.5keywords = tree (Clic here for more details about this article) |
3/18. Malignant melanoma arising from cutaneous bronchogenic cyst of the scapular area.bronchogenic cyst, an uncommon developmental anomaly that originates from the primitive tracheobronchial tree, is rare in the skin. The shoulder region is a particularly rare location. We report a 46-year-old Japanese man with recurrent malignant melanoma that arose from such a cutaneous bronchogenic cyst in the left scapular area. Despite wide local excision and subsequent chemotherapy, he died 18 months after surgery of the melanoma because of its lung metastasis. This is the first case of bronchogenic cyst in which malignant melanoma occurred.- - - - - - - - - - ranking = 0.5keywords = tree (Clic here for more details about this article) |
4/18. Cutaneous bronchogenic cyst of the abdominal wall.We report a case of the unusual location of a cutaneous bronchogenic cyst on the abdominal wall. The patient was a 9-month-old boy who had presented with a 1.5 cm-sized polypoid mass, present since birth. Pathological examination of the excised mass revealed multiple small cystic structures surrounded by the fibroadipose tissue. The lining epithelium consisted of either pseudostratified ciliated columnar epithelium with goblet cells or a single layer of ciliated or non-ciliated cuboidal to columnar cells. The cystic walls contained a well-developed smooth muscle bundle, mucous glands and hyaline cartilage plate. This lesion was adherent to the peritoneum, but there was no direct communication with the abdominal cavity. Cutaneous bronchogenic cyst located in the abdominal wall has not been described in the English literature. The present case suggests a possible origin from a downward migration, from the sequestered bud of a tracheobronchial tree primordium along the midline of the body surface, during embryonic development.- - - - - - - - - - ranking = 0.5keywords = tree (Clic here for more details about this article) |
5/18. A rare case of pulmonary bronchogenic cyst associated with bronchial atresia in the same lobe.A rare case of 49-year-old woman having pulmonary bronchogenic cyst associated with bronchial atresia in the same lobe was presented. The diagnosis was confirmed by aortography and operation specimen. Three-dimensional reconstructed images of computed tomography clearly demonstrated the defference between mucoid impaction of bronchial trees in the left S9 not communicating with hilar bronchus and the cyst in the left S10 oppressing surrounding vessels.- - - - - - - - - - ranking = 0.5keywords = tree (Clic here for more details about this article) |
6/18. A case of a bronchogenic cyst in a rare location.Bronchogenic cysts occur as a result of a developmental fault during the division and budding of the tracheobronchial tree in the embryonic period. They are usually located in the mediastinum and intrapulmonary regions. They may cause serious respiratory distress in childhood; they present less commonly in adults and often present with a variety of symptoms, including recurrent infections. We report the case of an adult female patient who presented with recurrent pulmonary infections and swelling of the neck because of a bronchogenic cyst that was unusually located in the cervical region.- - - - - - - - - - ranking = 0.5keywords = tree (Clic here for more details about this article) |
7/18. Cervical bronchogenic cysts: a consideration in the differential diagnosis of pediatric cervical cystic masses.OBJECTIVE: To discuss the clinical and histopathologic features of cervical bronchogenic cysts. methods: Retrospective case series. RESULTS: A 22-year pathology database search identified 24 patients 18 years of age and younger with bronchial/bronchogenic cysts, four of which presented in the cervical region. CONCLUSION: Cervical bronchogenic cysts are rare in the pediatric population but deserve inclusion in the differential diagnosis of cystic neck masses. Such cysts result from abnormal tracheobronchial tree development with characteristic pathology including respiratory-type epithelium, mural cartilage, smooth muscle, and seromucinous glands. Definitive treatment requires surgical excision.- - - - - - - - - - ranking = 0.5keywords = tree (Clic here for more details about this article) |
8/18. bronchogenic cyst of the gastric fundus presenting as a gastrointestinal stromal tumor.gastrointestinal stromal tumors (GIST) of the stomach are being recognized with increasing frequency. The diagnosis is usually made on the basis of appearance on computed tomography (CT) and excision is recommended for GIST larger than 5 cm. We report a 39-year-old woman referred for resection of a presumed GIST of the gastric fundus diagnosed by CT scan and upper gastrointestinal (UGI) series. A laparoscopic resection was performed, but upon pathologic examination the mass proved to be a bronchogenic duplication cyst of the stomach. Bronchogenic and esophageal duplication cysts usually arise in the chest or mediastinum. On rare occasions bronchogenic cysts may lose their connection to the tracheobronchial tree and migrate to a subcutaneous position in the neck or descend into the retroperitoneum. The importance of this case is that it demonstrates a rare yet essential component to the differential diagnosis of lesions of the stomach.- - - - - - - - - - ranking = 0.5keywords = tree (Clic here for more details about this article) |
9/18. Cervical bronchogenic cysts in head and neck region.Congenital cysts of the neck are not uncommon. Most of these are thyroglossal, branchial cleft and thymic cysts. Bronchogenic cysts are uncommon developmental anomalies of the tracheobronchial tree and rarely occur in the neck. More than 70 cases of bronchogenic cysts in the head and neck region have been reported in the literature. We report three cases presenting with neck swelling in the hyoid region that were diagnosed as bronchogenic cysts based on clinical and histopathological findings.- - - - - - - - - - ranking = 0.5keywords = tree (Clic here for more details about this article) |
10/18. Scapular bronchogenic cysts in children: case report and review of the literature.Cutaneous bronchogenic cysts (CBC) are rare solitary lesions which originate from primitive tracheobronchial tree. The periscapular location of these lesions is even a rare condition. The aim of this study is to evaluate this pathology after our case with literature review. An one-year-old girl was brought to our clinics with the complaint of a drainage at the back of her shoulder. In her physical examination, a hyperemic enduration with a sinus and purulent drainage was noted at the left scapular region. ultrasonography revealed a lesion of 15x11 mm2 in size with a thick wall and a hypoechoic center. The lumen of the cyst was demonstrated with fistulography. Surgical excision of the lesion was performed and pathological examination revealed a cutaneous bronchogenic cyst. CBC have been reported in 64 cases in the literature. They are often found in the lower neck, sternum and shoulders. They arise due to abnormal bronchial budding during the embryological period. Only in 12 of these patients, including our case, the lesion was located in the periscapular area. Its treatment is surgical because of malignant transformation and infection. The recognition of this entity may help the surgeon for early diagnosis.- - - - - - - - - - ranking = 0.5keywords = tree (Clic here for more details about this article) |
