A resected case of malignant fibrous histiocytoma of the chest wall

We report a 74-year-old woman with malignant fibrous histiocytoma (MFH), treated successfully by radiation and followed with chest wall resection and reconstruction. The patient suffered from right back pain and her chest X-ray showed a clear round shadow in the middle field of the right lung. Chest computed tomography (CT) showed a 5 x 5 cm tumor in diameter, involving the right 8 rib with destructive changes. After radiation therapy of total 30 Gy to the tumor to obtain the safety surgical margin, we widely resected 10 x 9 cm chest wall with 3 ribs in area under thoracoscopy and performed reconstruction using GORE-TEX Soft Tissue Patch. The pathological and immuno-histochemical diagnosis showed pleomorphic type of MFH. Final result of the tumor negative in surgical margin manifested that our technique of chest wall resection and reconstruction using thoracoscope after the irradiation to the tumor was very safe and useful.     

Multiple myeloma presenting as a solitary tumor of the rib; report of a case

A 78-year-old man complained of right lateral chest pain. Chest X-ray showed an abnormal shadow in the right upper lung field and chest computed tomography (CT) scan showed a lateral chest wall tumor sorrouding the right 4th rib. Bone scintigraphy revealed only one lesion in the right 4th rib. Chest wall tumor resection was done. Histological analysis of the tumor specimen showed plasmacytoma. After the operation, the diagnosis of multiple myeloma was established by demonstration of myeloma by a bone marrow biopsy. Multiple myeloma should be taken into account as one of causes of a chest wall tumor even if it is a solitary tumor of the rib.     

Chondrosarcoma of the ribs: report of two cases

Chondrosarcoma of rib origin is relatively rare in Japan. Two patients with chondrosarcoma of rib origin were treated surgically. Case 1: A 79-year-old male, 4 years ago, he noticed a tumor in the left anteroinferior part of the chest. The histological examination of the specimen obtained by incisional biopsy showed osteochondroma in another hospital and he had been under observation. Since the tumor has recently increased in size, he was referred to our department. Radical resection of the chest wall was performed. As expected, the tumor was found to be a secondary chondrosarcoma by postoperative histological examination. Case 2: A 49-year-old female. In the follow up studies after radical nephrectomy, Tc-MDP scintigram revealed an accumulation in the left second rib. Under the diagnosis of rib metastasis, radical resection was performed. The histological examination showed chondrosarcoma of rib origin postoperatively. This lesion was a primary central type, and is considered to have been resected in the earliest stage of all cases we have found in the Japanese literature.     

Mesenchymoma of the chest wall in children

Benign chest wall mesenchymoma in children is an extremely rare disease. Only 20 patients have been reported in the world literature. We report a chest wall mesenchymoma in a 2-year-old boy who was admitted to the hospital after a routine chest roentgenogram showed a mass in the right upper chest wall. The patient was asymptomatic. Clinical examination was negative, but chest roentgenograms and computed tomography showed a mass in the right upper chest wall involving the third rib. A 2 x 2 x 1.5-cm tumor was excised totally with partial resection of the third rib. The histology of the lesion corresponded to a mesenchymoma (hamartoma) of the chest wall. Our patient has been followed up for 8 years without recurrence.     

Resection of chondrosarcoma of anterior chest wall with pleural dissemination

A 52-year-old woman admitted with difficulty of breathing and had an anterior chest wall tumor. Primary lesion of the chest wall tumor invading the inferior one third of sternum, right third to sixth ribs, a part of the right middle lobe, the pericardium and a part of the diaphragma and small nodules on the parietal pleura were resected, and a diagnosis of chondrosarcoma of the right fifth or sixth rib and pleural dissemination of the tumor was established. The defect of pericardium was repaired with artificial dura mater and the defect of bony chest wall was repaired with a double layer of Marlex mesh. Although the resection was palliative because of pleural dissemination, she is now working as a housewife without difficulty of breathing.     

Malignant fibrous histiocytoma of the rib: a case report of repetitive extensive resections and reconstruction of the chest wall

A forty-seven-year-old woman visited our hospital in March 1987 suffering from the local recurrence of the tumor. Her right 7th and 8th rib had been resected 2 years and 11 months before because of the malignant fibrous histiocytoma (MFH) originated from the right 7th rib. In May 1987, wide resection of the right lateral chest wall and partial resection of the right diaphragm were done. Dacron meshed silicon plate (Silastic) and musculocutaneous flap of the right latissimus dorsi were used to reconstruct the chest wall. Seven months after the second operation, local recurrence occurred again on the anterior chest wall, involving the right diaphragm and right lower lobe of the lung. In March 1988, extensive resection of the anterior chest wall with partial resection of the right diaphragm and the right lower lobe was followed by reconstruction of the chest wall by Silastic. The patient recovered uneventfully without any respiratory disturbances after both operations which included wide resection of the chest wall. Multiple pulmonary metastases were found 4 months after the operation, and she died of respiratory failure 7 months after the final operation. Although MFH was one of the most common sarcomas of the soft tissues, only one case of the MFH originated from the rib had been reported previously in this country. Silastic was proved to be a useful prosthesis for the reconstruction of widely resected chest wall.     

Second chondrosarcoma of the rib four years after the initial operation; report of a case

Chondrosarcoma of rib origin is rare accounting for about 2% of all chondrosarcomas. A 63-year-old female with an anterior chest wall tumor was referred to our institution for surgical treatment of a 2nd chondrosarcoma in the right 2nd rib 4 years after the initial surgery for its primary lesion. Computed tomography (CT) showed a low density mass, 36 mm in diameter, arising from the 2nd rib. An extended excision of the chest wall including the tumor was performed followed by the reconstruction of the chest wall with double Marlex Mesh. As she had already undergone the reconstruction of the chest wall for its primary lesion, this reconstruction was her 2nd one. Nevertheless, her respiratory condition was well preserved with no significant chest deformity. Wide excision and reconstruction could be performed for the 2nd arising chondrosarcoma of the rib even after the initial lesion was already widely removed and reconstructed.     

Giant cell tumor expanded into the thoracic cavity with spinal involvement

This article describes a case of a giant cell tumor that expanded into the thoracic cavity and through the spinal canal into the vertebrae. A 36-year-old man presented with a 6-month history of back pain and dyspnea. Plain chest radiographs showed a huge mass accompanied by right pleural effusion. The mass involved the 12th thoracic spine, and the spinal cord was severely compressed. The tumor was resected with a 2-stage procedure. As a first stage to separate the tumor from the anterior vital structures under direct vision, thoracic surgeons performed a right thoracotomy with chest wall reconstruction from the 8th to 11th ribs. The right lung and inferior vena cava were gently retracted, and the tumor was carefully detached from these structures. We were not able to separate the tumor from the right diaphragm due to severe invasion; therefore, we performed partial resection of the right diaphragm with the tumor. After excision of the anterior part of the tumor, the thoracic wall was reconstructed with the right eighth rib and Marlex mesh. When the patient's general condition improved 2 weeks later, spondylectomy by posterior approach was performed. We achieved excision of a giant cell tumor that had expanded into the thoracic cavity and through the spinal canal into the vertebrae. The patient had achieved full rehabilitation with no neurological or respiratory abnormalities at 7 years postoperatively.     

Aneurysmal bone cyst arising in the rib; report of a case

We experienced with a relatively rare case of an aneurysmal bone cyst (ABC) arising in the left rib. A 34-year-old female, had experienced chest discomfort on the left anterior side and pain for 1 year. A chest X-ray suggested a left chest wall tumor involving the ribs. Computed tomography (CT), magnetic resonance imaging (MRI) and a bone scintigram revealed an expansive tumor of the anterior portion of the left 4th rib involving the 3rd and 5th rib with "blow out appearance" and "fluid-fluid level". Wide excision of the tumor and adjacent muscle tissue was performed with an antero-axillary incision. Chest wall reconstruction was performed with prolene mesh (140 x 90 mm). The resected specimen showed an encapsulated bony mass (75 x 60 x 35 mm) with multiple blood-filled spaces. Histopathological diagnosis was an ABC originating in the left 4th rib. She has been doing well with no evidence of recurrence 12 months postoperatively.     

A case of giant cell tumor originating from the rib

We have experienced a case of giant cell tumor originating from the rib. A 45-year-old male was admitted to our hospital because of a mass in the left chest wall. A tumor shadow was observed in the left side of chest X ray. Chest CT, bone scintigram showed tumor originating from the left 4th rib. The tumor was suspected giant cell tumor of bone by needle biopsy examination. The tumor was completely resected with chest wall surrounding the tumor. The defect of chest wall was reconstructed with Marlex mesh and the Latissimus dorsi muscle flap. The pathological diagnosis was a giant cell tumor of bone. The patient has been well for two years and one month since surgery, with no signs of recurrence.     

Thymic carcinoma with combined resection of the hemisternum

We report a case of partial resection of the hemisternum of a thymic carcinoma invading the right anterior chest wall. A computed tomographic scan of the chest and positron emission tomography showed a mass invading the right anterior chest wall in the anterior mediastinum with high 18F-fluorodeoxyglucose accumulation. An operation was performed to obtain a definitive diagnosis and achieve complete resection. First, we assessed the boundaries of gross disease using left-sided video-assisted thoracoscopy. After delineating the margins of the lesion invading the anterior chest wall, a median sternotomy was added and the tumor was resected with the right half of the sternum, parts of the right third and fourth costal cartilages, part of the right upper lung lobe, and pericardium. Histopathological evaluation revealed a squamous cell carcinoma of the thymus with direct invasion to the right lung, pericardium, and the right third costal cartilages.     

Hepatocellular carcinoma associated with hemorrhaging from iatrogenic rupture of a rib metastasis

Detecting a rib metastasis as a first manifestation before identifying hepatocellular carcinoma (HCC) is rare. We report an HCC with massive bleeding from the biopsied rib tumor. A 68-year-old man was referred for right chest pain. Computed tomography showed a mass in the rib and two small masses in the liver. The biopsied rib continued to bleed, so we removed the entire tumor, including the rib. We histologically confirmed the diagnosis as rib metastasis from the HCC. The patient died 3 months after the onset. We caution against performing an incisional biopsy without due consideration.     

Hemangioma of the rib

An asymptomatic 48-year-old woman presented to our hospital with a tumor of the rib incidentally diagnosed on a chest roentgenogram. The patient was investigated and underwent tumor resection of the chest wall. The pathologic study revealed that it was cavernous hemangioma. This tumor of the bone is a distinctly uncommon benign vascular tumor, generally occurring in the spine or skull. Hemangiomas involving the rib are even more rare, with only 22 cases described in the literature. However, we suggest that this tumor of the rib should be considered in the differential diagnosis, principally in asymptomatic patients.     

Primary hemangiopericytoma of the chest wall--a case report]

An extremely rare case of a primary hemangiopericytoma of the chest wall was reported. A 40-year-old female without any complaints was detected to have an abnormal shadow in the right chest wall on a chest X-ray film. The tumor was 2.6 x 2.2 x 2.0 cm in size and was resected together with the 8th rib which adhered to the tumor. Postoperative pathohistological examination led to the diagnosis of hemangiopericytoma. Postoperative course was uneventful, and the patient is now doing well and has had no recurrence for 11 months since the operation. A brief review was made on 9 cases collected from the literature.     

A case of chest wall reconstruction with scapular flap and rib autotransplantation for recurrent esophageal cancer

Subtotal esophagectomy was carried out for esophageal cancer in a 64-year-old male patient. The postoperative stage was a1, n2, stage III. From around 10 months after surgery, a recurrent tumor of first size was recognized at the right anterior lateral thoracic wall, corresponding to the site of the thoracotomy wound, and the tumor involved the right 4th 5th ribs and the subcutaneous soft tissue including the pectoralis major and latissimus dorsi muscles. Total layer chest wall resection including 3rd to 6th ribs, with the tumor was performed. In order to reconstruct the cutaneous soft tissue, a scapular skin flap with vascular pedicle of the circumflex scapular artery and vein was made. Moreover, for the purpose of reinforcing the osseous thoracic wall, a free autogenous rib was transplanted; namely, the 7th rib was cut in half lengthwise and then fixed like a bridge at the center of the defective site of the thoracic wall. Finally, the region was covered with the scapular skin flap for the chest wall reconstruction. After the surgery, supplemental ventilation was not necessary. Although fracture of the transplanted rib was recognized at month 2, the thorax was stable, even immediately after the surgery. Therefore, this method is considered to be useful for reconstruction after total layer chest wall resection.     

Temporary claviculectomy approach for plexiform neurofibroma of the first intercostal nerve

Plexiform neurofibroma at the thoracic inlet has rarely been reported and to our knowledge, the use of a temporary middle claviculectomy approach for thoracic inlet tumors has never been reported. We report a case of plexiform neurofibroma of the first intercostal nerve resected using a temporary claviculectomy approach. An abnormal shadow detected radiographically in a 16-year-old boy led to a diagnosis of neurofibromatosis 1 (NF-1) with a chest wall tumor at the thoracic inlet. The patient underwent resection of the tumor with the right first rib. The resected clavicle was reapproximated with a plate and postoperative shoulder function was satisfactory. The tumor was diagnosed pathologically as a plexiform neurofibroma and the patient’s postoperative course was uneventful. The temporary middle claviculectomy approach provides excellent exposure of the subclavian vessels and brachial plexus before resection of the tumor. We recommend this approach for tumors of the anterior thoracic inlet.     

Solitary plasmacytoma of the rib

Solitary plasmacytoma of the bone, and especially of a single rib, is a rare disease. Here we report a 73-year old male patient complaining of continuous chest wall pain around the right 5th rib shaft who underwent a wide excision of the rib tumor with surrounding connective tissue. He was diagnosed with solitary plasmacytoma and will undergo radiation therapy. We report this case with a review of the literature.     

Chondrosarcoma of rib origin; report of a case

Chondrosarcoma of rib origin is rare. A 50-year-old man without symptom was pointed out an abnormal shadow on chest X-ray. Computed tomography (CT) showed a low density mass arising from the right chest wall, and a CT-guided needle aspiration biopsy disclosed the tumor consisted of cartilage matrix with a partial necrosis. We suspected the tumor to be a chondrosarcoma of rib origin and performed a wide resection with the right 3rd and 4th ribs. The defect of the chest wall was repaired with double prolene mesh. Histological examination revealed grade 2 chondrosarcoma. Postoperative course has been uneventful for 25 months.     

Seat belt-related chondrosternal disruption with lung herniation

A case of blunt chest trauma resulting in anterior chondrosternal separation with right lung herniation and hemothorax is presented. The injury is related to the use of a seat belt restraint. The patient underwent surgical repair with polytetrafluoroethylene chest wall reconstruction. Postoperative recovery was complicated by respiratory insufficiency due to underlying pulmonary contusion and multiple rib fractures.     

Symptomatic anterior sternoclavicular joint secondary to a bicipital rib

This case report details the diagnosis and treatment of a previously unreported complication of a congenital chest wall anomaly. Our patient presented with a painful anterior sternoclavicular joint subluxation secondary to a bicipital rib. Thoracic magnetic resonance and computed tomographic imaging provided the diagnosis. Complete resolution of symptoms was achieved after resection of the bicipital rib.
