So-called carcinosarcoma of the esophagus is rare malignant tumors composed of carcinoma and sarcomataous components. We described a case of so-called carcinosarcoma and reviewed some literature. A 67-year-old man visited our hospital because of difficulty in swallowing, general fatigue, and
sore throat
. Barium swallow esophagogram showed a large polypoid lesion in the middle, lower thoracic esophagus. Endoscopy also demonstrated a pedunculated polypoid tumor. Histological examination of the biopsy specimen revealed malignant findings.
Thoracic
esophagectomy with cervical, thoracic, abdominal dissection was performed. A polypoid tumor, 10.5 x 5.2 x 3.5 cm in size, was removed. In the polypoid lesion, spindle-shaped cells made interlacing bundles similar to sarcoma and surrounded nests of squamous cell carcinoma. Near the pedicle, squamous cell carcinoma invaded muscularis mocosae. And lymph node metastasis was detected. Epitherial membrane antigen (EMA) was detected in some parts of the polypoid lesion. So according to Guide Lines for Clinical and Pathological Studies on Carcinoma of the Esophagus, this case was diagnosed as so called carcinosarcoma.

The impact of bioaerosols in municipal solid waste management is nowadays identified as a growing health concern worldwide. In this study, exposure to endotoxin in composting facilities and its association with lung function and clinical symptoms was investigated in Tehran municipal solid waste management complex (Aradkooh) as one of the largest solid waste management facilities in the Middle East. Airborne endotoxins were collected between June and July 2019 and the concentrations were determined by Limulus Amebocyte Lysate (LAL) method. Healthy workers with no history of respiratory disease were recruited and data on clinical symptoms (cough, phlegm, wheezing, dyspnea, fatigue, headache, eye irritation, runny nose, runny eyes, and
sore throat
) was obtained by the modified American
Thoracic
Society questionnaire, and spirometric measurement was performed by an expert. The binary logistic regression test was used and adjusted for confounding variables. The results didn't show any difference in lung function parameters (FEV

, FVC, FEV

/FVC, PEF, FEF
25-75%
), and most of the respiratory symptoms despite a relatively high difference in the concentration of endotoxin observed in air samples of different locations. Only the increased risk of cough (OR 10.5, 95% CI: 2.4 to 44.8 in the moderately exposed group and 7.8, 95% CI: 1.6 to 39.1 in highly exposed ones), fatigue (OR 3.7, 95% CI: 1.2 to 11.7), and headache (OR 6.02, 95% CI: 1.4 to 24.5) were found in the exposed groups compared to controls after adjusting for age, active and passive smoking. However, findings of the study might be underestimated due to some issues including healthy worker effect, intra and intersubject variability, and self-reporting bias, thereby the results should be interpreted with caution. Although we did not find any relationship, due to the high concentrations of endotoxins observed in some sites, it is recommended to consider some possible prevention measures such as using personal protective equipment to reduce the exposure of workers at an acceptable level.
