The granulation tissue, which are found in nonspecific inflammation, occasionally seemed like round mass. We experienced and report four cases in which the granulation tissue presented as endobronchial mass on the bronchoscopy. The masses obstructing lobar or segmental bronchial oriface were round, smooth surfaced and pinkish except whitish one case. The granulation tissue caused by acute or chronic inflammations, should be considered to differentiate endobronchial mass.

Buckwheat belongs to the Polygonacea or buckwheat family and is not a true cereral since it does not belong to the Graminiae, or grain family. Its products have long been considered excellent foods for both human and animal consumption.

The earlist reference to case of buckwheat sensitivity was a report by Smith in 1909. He accurately described a case of angionerotic edema and urticaria in a young man upon ingestion accurately described a case of angionerotic edema and urticaria in a young man upon ingestion of small amounts of buckwheat, and violent asthma on the ingestion of moderate quantities of buckwheat.

The authors have experienced one case of buckwheat allergy. The chief complaints were wheezing and dyspnea for several years. The skin tests showed positive reaction to the extracts of buckwheat flour and buckwheat husk. The buckwheat allergy is considered to be the model of the typeIallergy(that is lgE dependent type) proposed by Cooms and Gell. The antigenicity of buckwheat is extremely string, so oral provocation test must not easily be applied for fear of severe and dangerous reaction.
