negative. He stated that at an early age he received a
stroke of lightning, which rendered him unconscious for some time. He
knows of nothing else that could be in possible relation with his
present condition. Nine months after this accident there was noticed
an enlargement of the middle joint of the little finger, and about the
same time an enlargement on the middle finger. Gradually all the joints
of the right hand became involved. The enlargement increased so that at
the age of twelve they were of the size of walnuts, and at this time
the patient began to notice the same process developing in the left
hand. The growths continued to develop, new nodules appearing, until
the fingers presented the appearance of nodulated potatoes.

One of the most frequent of the fibro-cartilaginous tumors is the
"mixed cartilaginous" tumor of Paget, which grows in the interstitial
tissues of the parotid gland, and sometimes attains enormous size.
Matas presented the photograph of a negress having an enormous fibroma
growing from the left parotid region; and there is a photograph of a
similar case in the Mutter Museum of the College of Physicians,
Philadelphia.

The hyaline enchondroma is of slow growth, but may at times assume
immense proportions, as is shown in the accompanying illustration,
given by Warren, of a patient in whom the growth was in the scapula.

In 1824 there is quoted the description of a peculiar growth which,
though not definitely described, may be spoken of here. It was an
enormous encysted tumor, springing from the clavicle of a Veronese
nobleman. Contrary to general expectations it was successfully removed
by Portalupi, a surgeon of Venice. It weighed 57 pounds, being 20 1/2
inches long and 30 inches in circumference. It is said this tumor
followed the reception of a wound.

Among the benign bone tumors are exostoses--homologous outgrowths
differing from hypertrophies, as they only involve a limited part of
the circumference. When developmental, originating in childhood, the
outgrowths may be found on any part of the skeleton, and upon many and
generally symmetric parts at the same time, as is shown in Figure 248.

Barwell had a case of a girl with 38 exostoses. Erichsen mentions a
young man of twenty-one with 15 groups of symmetric exostoses in
various portions of the body; they were spongy or cancellous in nature.

Hartmann shows two cases of multiple exostoses, both in males, and
universally distributed
