Pathological Remarks on the Kind of Palpebral Tumour Usually Called, in England, Tarsal Tumour

Abstract

THE subject of tuinours of the ocular appendages is obscurely treated of by writers, more, I believe indeed, than any in the whole range of ophthalmological literature. The several stages of the same affection are described as different diseases, and the same diseases are dissimilarly delineated. A Greek and a Latin word bearing the same signification,-Chalazion and Grando, are applied to different morbid states. The disease I now propose to treat of is involved in similar perplexity; for I find it spoken of as "fibrinous tumour," "tarsal tumour not encysted," "albuminous tumour," and by other terms equally erroneous. There is also disagreement concerning its connection, whether moveable or not, and even as to consistence, whether hard or soft. I propose, therefore, in order to be understood respecting the tumour I mean, to describe the most palpable objective characteristics, before I point out what appears to be its pathological condition, and which has not, so far as I am aware, ever been demonstrated. Commencing, then, with the external characters, I would speak of it as a hard, spherical, well-defined tumour, in size
