It is the commonest chest emergency encountered by general surgeons. Sometimes, in acute situations, even physicians may be required to perform the procedure as a ‘life-saving’ measure. Hence, we feel that doctors in all specialties should be able to insert a chest tube safely.

ABSTRACT

Endobronchial fibroleiomyomatous hamartoma: a diagnostic pitfall

The Japanese Journal of Thoracic and Cardiovascular Surgery, Jul 1, 2010

Fiberoptic bronchoscope-guided biopsy of the mass on two occasions showed acute-on-chronic inflammation. The origin of the polyp was the right upper lobe bronchus; and upper lobectomy with adequate resection margin was done. Histopathology examination of the polyp showed features compatible with benign fibroleiomyomatous hamartoma. True fibroleiomyomatous hamartoma arising primarily in the lung is rare and presents as a pulmonary parenchymal lesion. the endobronchial variant of this tumor is extremely uncommon and not well documented in the literature. A preoperative diagnosis is difficult, and a high index of suspicion is required for diagnosing this benign neoplasm.

Such tumors usually present with signs and symptoms of bronchial obstruction. Histologically, they can be classified as high-grade or low-grade tumors. Experience of imaging these tumors with 18 fluorodeoxyglucose positron emission tomography-computed tomography ( 18 F-FDG PET-CT) is limited. We present three cases of this rare tumor, describe the functional imaging results, and review the available literature. Case presentation: Three Caucasian patients, two men (21 and 24 years of age) and one woman (14 years of age), with bronchial masses were evaluated by us. All three patients were symptomatic, and underwent a thorough clinical examination, bronchoscopy and biopsy, plain computed tomography, 18 F-FDG PET-CT and 68 Gallium 1,4,7,10-Tetraazacyclododecane-N I ,N II ,N III ,N IIII ,-tetra acetic acid (D) -Phel 1 -Tyr 3 -octreotide positron emission tomography-computed tomography ( 68 Ga-DOTATOC PET-CT). 18 F-FDG PET-CT revealed mild uptake in all three patients, whereas 68 Ga-DOTATOC PET-CT revealed no significant uptake in any patient, making carcinoid tumor unlikely. Results of histopathological examination were consistent with low-grade mucoepidermoid carcinoma in all patients.

A separate tumour in the posterior mediastinum was also detected. Both the tumours were immunohistochemically and histomorphologically compatible with benign schwannoma. Oesophageal schwannoma is extremely rare and its association with a concurrent schwannoma in posterior mediastinum is not reported earlier in the literature.

Thirty-five patients with mediastinal lymphadenopathies without primary neoplastic or infective lung pathologies were included in the study. The lymph nodes were detected on contrast-enhanced CT scan of the chest. All patients underwent (18)F-FDG PET-CT scan for evaluation of mediastinal lymph nodes. Results of PET-CT were compared with histopathology of the lymph nodes and sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated. The data were collected prospectively and analyzed using (SPSS Inc., Chicago, IL) 11.5 software. Histopathology results in 35 patients revealed tuberculosis in 12, sarcoidosis in 8, and lymphoma in 15. Maximum standardized uptake value (SUVmax) of the benign lymph nodes ranged from 2.3 to 11.8 with a mean±standard deviation (SD) of 5.02±3.26. SUVmax of the malignant lymph nodes ranged from 2.4 to 34 with a mean±SD of 10.8±8.12. There was a statistically significant difference between benign and malignant pathology (P&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.0059). (18)F-FDG PET-CT has sensitivity of 93% and specificity of 40% with SUVmax 2.5 as the cutoff. We found the optimal SUVmax cutoff to be 6.2 as determined by the receiver-operator characteristic curve. With 6.2 as cutoff, the sensitivity, specificity, and accuracy were 87%, 70%, and 77%, respectively. In countries where tuberculosis and other granulomatous diseases are endemic, SUVmax cutoff value of 2.5 has low specificity. Increasing the cutoff value can improve the specificity, while maintaining an acceptable sensitivity.

We report one such case in a 44-year-old male patient with invasion into the upper 2/3rd of the sternum but no endocrinopathy. Complete enbloc resection of the tumor with adherent pericardium, upper 2/3rd of the sternum and mediastinal lymphadenectomy was performed. The chest wall was reconstructed with polypropylene mesh and bilateral pectoralis major muscle advancement flap cover. A search of PubMed database with user query words 'neuroendocrine carcinoma, thymus gland, sternal invasion' revealed no case report in the literature of thymic neuroendocrine carcinoma with invasion of the sternum.

Direct laryngoscopy and flexible endoscopy confirmed the origin from pharyngo-oesophageal junction. Lateral cervical oesophagotomy and excision of a polypoidal mass of 15x6.5x3 cm size was done. Histopathology revealed fibrovascular polyp (FVP) arising from submucosa of oesophagus. FVP is a benign tumour-like condition which can attain an enormous size inside the lumen of the oesophagus. It predisposes the patient to aspiration due to incomplete vocal cord adduction and asphyxia due to possible laryngeal inlet block and thus, threatening life. Complete surgical excision through lateral oesophagotomy is the standard treatment and provides cure in the majority of cases.

Although carcinoid tumors usually have good prognosis, early and specific diagnosis is important.... more Although carcinoid tumors usually have good prognosis, early and specific diagnosis is important. Computed tomography and magnetic resonance imaging do not provide findings that are specific for carcinoids, and somatostatin receptor scintigraphy suffers from low spatial resolution. 18-Fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) has limited sensitivity for carcinoids due to low uptake of the marker. A PET/CT system that uses the somatostatin receptor-based PET tracer 1,4,7,10-tetraazacyclododecane-N(I),N(II),N(III),N(IIII)-tetraacetic acid (D)-Phe(1)-thy(3)-octreotide ((68)Ga-DOTATOC) has also been used in the evaluation of carcinoids, although information regarding its use for the detection of primary pulmonary carcinoids is limited. Thus, we investigated the value of (68)Ga-DOTATOC PET/CT for the diagnosis of primary pulmonary carcinoid tumors. This was a retrospective analysis of patients with primary pulmonary tumors who underwent (68)Ga...
