    3 SECTION V—DISEASES OF THE FRONTAL SINUSES. 141 | I is so small that it is hardly possible to draw conclusions of pathological interest from them, but they serve to show that the frontal sinuses may be the starting points of true bony growths, and that in other cases the growths may commence in the ; diploe of the frontal bone, and invade the sinuses afterwards in l the progress of their growth. I Case,—J. Arnold reports in Virchow's Archiv, vol. Ivii, two ! bony tumours of the anterior region of the skull, which are remarkable examples of what has been called by Virchow I enostosis, or osteoma developed from the diploe. Both tumours \ agreed almost entirely in their situation and mode of development, j but differed in the rate of growth, in that one only of them j represented an advanced stage. Both had their origin at the ' posterior and lower part of the wall of the frontal sinus, where the ; ethmoid bone approaches the part (here alone was there a close j connection between the tumours and the wall of the sinuses), and thence grew into and distended the sinuses. One of them broke ■ through the wall at separate points above, below, and in front; . j the large projections of the other pressed on the orbits, nasal cavities, and skull, destroying the anterior lamellse of the frontal ! bone, so that the only guide to its origin in the frontal sinus was i the presence on it of some mucous membrane with ciliated epithelium. ' ; Both tumours had a thin layer of connective tissue on their outer ] surface. The smaller one consisted entirely of ivory-like masses, while the larger one had this structure on the outside only, the interior being formed of a spongy tissue. Arnold believes that I in these two cases, and in twelve others of which he has been able i to find records, the tumours must have either been developed from the endosteum by the direct formation of bone-substance, ! or by bony transformation of enchondromata which themselves i had their origin from the endosteum or from the remains of cartilage. In one of Arnold's cases, the patient was only twenty- three years of age ; and Yirchow has already observed that the ]. occurrence of the disease in early life points to its origin, in ; many cases, in disturbance of the formation of bone.—Extract | from the British Medical Journal, Feb. 14, 1874. j
