Cystic lymphangioma: report of two atypical cases

Erkan Yildirim; Koray Dural; Tevfik Kaplan; Unal Sakinci

Cystic lymphangioma is an uncommon congenital benign neoplasm, which frequently occurs to children and young adults and acquired form may be detected in middle-aged adults. Cystic lymphangioma usually appears in the neck, the axillary region, and the mediastinum. In the first case, cystic lymphangioma located in the posterior mediastinum extending over the vertebral column to the both hemi thoraces. In the second one, it was palpated on the posterior chest wall at the level of T6-8 vertebrae. In the view of literature, these cystic lymphangioma are accepted to be atypical because of their locations.

OBJECTIVES Elastofibroma dorsi (ED) is a rare, benign lesion arising from connective tissue, usually found at the inferior pole of the scapula. To date, only a few small series have been reported in the English literature and there are few data about the long-term outcomes after surgery. Our goal is to contribute a better understanding of this tumour and to determine the long-term outcomes after surgery. METHODS Sixteen patients with a diagnosis of ED were identified from the units database. The clinical presentation, diagnosis, pathological evidences and long-term outcomes were evaluated. RESULTS There were 11 females and 5 males with a mean age of 61.1 years (range 38-78 years). The tumour was located on the right in 5 (31.2%) patients, on the left in 6 (37.5%) patients and bilaterally in 5 (31.2%). Six patients had painful scapular swelling resulting in restriction of movement of the shoulder whereas 10 reported only painful scapular mass. All 16 patients underwent complete resections. The tumour size ranged from 3 to 15 cm. The mean hospital stay was 3.1 ± 1.4 days with a morbidity of 18.75% (seroma observed in 3 patients). The mean follow-up was 58.4 ± 29.5 months (range 11-92 months). In 2 patients (12.5%) a new occurrence on the contralateral side was observed at the follow-up. CONCLUSIONS Elastofibroma dorsi is a rare, ill-defined, pseudotumoural lesion of the soft tissues. Surgical treatment can be proposed if the lesion is symptomatic. Furthermore, at the follow-up, the possibility of new occurrences on the contralateral side should be kept in mind.

Unusual location of arteriovenous malformation; posterior mediastinum

Tevfik Kaplan; Bayram Altuntaş; Sami Ceran; Güven Sadi Sunam

An arteriovenous malformation is an anomaly of capillary development that results in a direct connection between branches of an artery and veins, with no intervening capillary network. Vascular malformations of the mediastinum presenting as mediastinal masses are very rare. We report a histologically proven case of a posterior mediastinal arteriovenous malformation in a 42-year-old man that was incidentally detected by chest radiography during a routine health check. We discuss arteriovenous malformation and review the literature findings.

BACKGROUND The aim of this study was to evaluate the pulmonary reserve of the patients via preoperative quantitative computerized tomography (CT) and to determine if these preoperative quantitative measurements could predict the postoperative pulmonary morbidity. METHODS Fifty patients with lung cancer who underwent lobectomy/segmentectomy were included in the study. Preoperative quantitative CT scans and pulmonary function tests data were evaluated retrospectively. We compare these measurements with postoperative morbidity. RESULTS There were 32 males and 18 females with a mean age of 54.4±13.9 years. Mean total density was -790.6±73.4 HU. The volume of emphysematous lung was (<-900 HU) 885.2±1,378.4 cm(3). Forced expiratory volume in one second (FEV1) (r=-0.494, P=0.02) and diffusion capacity of carbon monoxide (DLCO) (r=-0.643, P<0.001) were found to be correlate with the volume of emphysematous lung. Furthermore FEV1 (r=0.59, P<0.001) and DLCO (r=0.48, P<0.001) were also found to be correlate with mean lung density. Postoperative pulmonary morbidity was significantly higher in patients with lower lung density (P<0.001), larger volume of emphysema (P<0.001) and lower DLCO (P=0.039). A cut-off point of -787.5 HU for lung density showed 86.96% sensitivity and 81.48% specificity for predicting the pulmonary morbidity (kappa =-0.68, P<0.001). Additionally a cut-off point of 5.41% for emphysematous volume showed 84.00% sensitivity and 80.00% specificity for predicting the pulmonary morbidity (kappa =0.64, P<0.001). According to logistic regression analyses emphysematous volume >5.41% (P=0.014) and lung density <-787.5 HU (P=0.009) were independent prognostic factors associated with postoperative pulmonary morbidity. CONCLUSIONS In this study, the patients with a lower lung density than -787.5 HU and a higher volume of emphysema than 5.41% were found to be at increased risk for developing postoperative pulmonary morbidity. More stringent precautions should be taken in those patients that were found to be at high risk to avoid pulmonary complications.

We present a rare case of intercostal lung herniation due to blunt trauma. A 40-year-old man was admitted to our hospital with lung herniation due to falling off a donkey. Computed tomography demonstrated a fracture of the 8th left rib, a comminuted fracture of the 9th rib, and lung herniation into the 8th intercostal space. The herniation was repaired using a titanium prosthetic rib, a rib plate, and Prolene mesh via a thoracotomy.

An Unexpected Complication of Titanium Rib Clips

Tevfik Kaplan; Gultekin Gulbahar; Ahmet Gokhan Gundogdu; Serdar Han

Surgical stabilization of the rib fractures has been successfully performed for the management of pain in multiple rib fractures, fixation of chronically painful nonunion, reduction of overriding ribs, and flail chest cases. Herein we report a patient who was treated with titanium rib clips after a motor vehicle accident leading to pulmonary parenchymal laceration and multiple painful rib fractures. Three of the rib clips were broken 4 months after the operation. The patient underwent the second operation for restabilization of the broken ribs. We review the relevant literature, with particular emphasis on the management of this complication.

Thymoma type B1 arising in a giant supradiaphragmatic thymolipoma.

Tevfik Kaplan; Serdar Han; Unsal Han; Gokce Kaan Atac; Serdar Yanik

Thymolipomas are uncommon tumors of the anterior mediastinum. They may extend into, but rarely stem from, the chest cavity. Furthermore, thymoma arising in a thymolipoma is extremely rare. We report a unique case of thymoma type B1 that originated form a giant thymolipoma located in the chest cavity, which was resected by a lateral thoracotomy in a 23-year-old woman. To our knowledge, this is the first reported case of thymoma type B1 arising within a giant thymolipoma.

Traumatic pulmonary pseudocyst due to thoracic trauma

Gultekin Gulbahar; Ahmet Gokhan Gundogdu; Tevfik Kaplan; Bulent Kocer

Traumatic pulmonary pseudocyst is uncommon and usually regresses spontaneously with conservative treatment. In rare cases, surgical intervention may be necessary. A pseudocyst may be treated surgically to prevent potential complications if the patient undergoes a thoracotomy for another reason. We present a patient with hemopneumothorax and traumatic pulmonary pseudocyst after a motor vehicle accident, who was operated on electively due to massive air leak.

Tevfik Kaplan; Nesimi Günal; Gultekin Gulbahar; Bulent Kocer; Serdar Han; Mehmet Ali Eryazgan; Arzu Ozsoy; Seniha Naldoken; Aslıhan Alhan; Unal Sakinci

BACKGROUND  Tietze syndrome (TS) is an inflammatory condition characterized by chest pain and swelling of costochondral junction. Primary chest wall tumors may mimic TS. In this article, we report our experience of approximately 121 patients initially diagnosed as TS and determined chest wall tumor in some cases at the follow-up. METHODS  This is a retrospective review of patients diagnosed as TS by clinical examination, chest X-ray, electrocardiogram, routine laboratory tests, and computed tomography (CT) of chest: all treated and followed up between March 2001 and July 2012. There were 121 cases (41 males and 80 females; mean age, 39.6 ± 3.2 years) of TS. RESULTS In 27 patients with initial normal radiological findings, the size of swellings had doubled during the follow-up period (mean, 8.51 ± 2.15 months). These patients were reevaluated with chest CT and bone scintigraphy and then early diagnostic biopsy was performed. Pathologic examination revealed primary chest wall tumor in 13 patients (5 malignant, 8 benign). CT had a sensitivity of 92.3% and a specificity of 64.2% in detection of tumors (kappa: 0.56, p = 0.002), whereas the sensitivity and the specificity of bone scan were 84.6 and 35.7%, respectively (kappa: 0.199, p = 0.385). CONCLUSION  Primary chest wall tumors could mimic TS. Bone scintigraphy or CT is not specific enough to determine malignant and other benign disorders of costochondral junction. Therefore, clinicians should follow TS patients more closely, and in case of increasing size of swelling, early diagnostic biopsy should be considered.

A Rare Entity: Bilateral First Rib Fractures Accompanying Bilateral Scapular Fractures

Gultekin Gulbahar; Tevfik Kaplan; Hasan Bozkurt Turker; Ahmet Gokhan Gundogdu; Serdar Han

First rib fractures are scarce due to their well-protected anatomic locations. Bilateral first rib fractures accompanying bilateral scapular fractures are very rare, although they may be together with scapular and clavicular fractures. According to our knowledge, no case of bilateral first rib fractures accompanying bilateral scapular fractures has been reported, so we herein discussed the diagnosis, treatment, and complications of bone fractures due to thoracic trauma in bias of this rare entity.
