[Pharynx perforation caused by fishbone--diagnostic problems].

The authors presented a case of perforation of the left side of pharynx by fishbone, treated successfully in spite of wrong primary diagnosis and treatment. The fishbone quickly penetrated the pharynx wall and evoked inflammatory process similar to thyroid gland tumor (size 50 x 70 mm). It was the cause of the wrong first diagnosis of thyroid gland tumor. Because of the diagnosis the patient was qualified to surgical intervention--the removal of thyroid tumor. However, the patient suspected the relationship between the tumor and choking with a foreign body. The patient was diagnosed again in another hospital where the proper diagnosis was made. The removal of fishbone from the left subclavian region was performed after 41 days from the day of choking.
