Of some Extraordinary Tumors on the Head of a Labouring Man in St Bartholomew's Hospital. By James Parsons, M. D., F. R. S. p. 350. This poor man, whose name was John Tomlinson, gave this account of himself: that he was about 25 years of age: that when he was a boy of 4 or 5 years old at play with other children, he received a blow from one of them on the top of his head, and believes that hurt he then received was the beginning of the tumours. The tumour on the top of his head however grew first, and after having spread all over the vertex, extended gradually downwards over his right shoulder, and forwards over the os frontis, on the same side, till it stretched downwards into a lax flabby substance all over the right side of his face and shoulder: then the upper of three anterior tumours arose from the large one; the middle one from the ala nasi, pulling it down by its weight: and the lower one was pendulous from the inside of the great tumour by a narrow neck. These were the appearances which presented themselves at first sight; but those under the great tumour were no less extraordinary; for on lifting up the great tumour, and looking up under it, his right eye came in sight, with which he saw very well, and the eye was clear and sound; but the under lid was pulled down and stretched to 6 or 7 inches long, to which a tumour hung also, as large as that anterior one at the chin, the lowest of the three; besides several flaps and rugæ of skin and smaller tumours. The hairy scalp was so stretched by the vertical tumour, that the hairs were driven asunder; so that the tumour was in some places bald, and the whole was rugged and uneven. At its basis all round, till arriving at the extended part that went away to the right shoulder, a bony edge might be distinctly felt, as if the skull was depressed at the top: and yet probably there was no depression of the arch of the inner table, because the man was from his childhood ever very healthy; being never troubled with those symptoms which usually attend a depression of the cranium. From this seeming edge the os frontis shot out a great way over the ossa nasi, perhaps to 2 or 3 inches beyond the frontal sinuses; and was the basis from which the great pendulous tumour hung downwards and forwards. From the root of the nose under the upper of the 3 smaller tumours arose a large trunk of a vein, which ramified up to the vertical tumour, and to the right over the upper part of the great pendulous one: these were very conspicuous, and served to bring back the residual blood from the tumours: nor was it unlikely that the arteries bore a proportion with these veins in their size, in order ta supply the tumours with the matter which had given them their great increase; but these lying concealed, could not be spoken to with any certainty. |
