緒言
眞性の皮角(Cornu cutaneum)は皮膚科疾患の中でも極めて少なく,その報告例としては頭部,顔面,稀に四肢,躯幹,男性外陰部の皮膚に発生するものが挙げられる.粘膜にくるものとしては更に少なく,口唇,頬部粘膜又は結膜の皮膚との移行部に発生するととが知られている.
私は最近これが一側声帶に原発している例に遭遇し,文献史上教室先輩川野の欧文報告を除いて未だその例に接しないので,その臨床例を述べることにする.
Muta presents a case of cornu cutaneum of larynx, an affection exceedingly rare in occurrence. Thus far only two cases of this nature has been reported in the literature of this country including the present one.
A man, 65 years old Buddhist Priest, reported to complain that he felt as though a foreign body is lodged in his throat ; his voice had been hoarse for the past 4 months. Indirect larygeal examination revealed a tumor which occupied the anterior half of the right vocal cord, the color of which was whitish and hard in appearance. The mass after being removed weighed slightly less than 0.1 gm. with external measurements, 0.7×0.3×0.2 cm. Microscopic diagnosis of the growth was established as cornu cutaneum. No congenital cause was recognizable in connection with its etiology but, it may have been possibly brought on by presence of postnasal discharge from which the patient suffered as result of his chronic paranasal sinusitis and which acted as a source of incessant stimulation upon the vocal cord by dropping down from the naso-pharynx above. As to paucity of records of this affection in the literature the author questions whether it is not due to the fact that the disease had been overlooked because of insufficient interest in the examination of patients.
