    are soft, others firm: in their form they may be broad and pointed: sometimes they are attached by a pedicle, and very often their extremities resemble a mulberry, a cauliflower, or a cock's comb. They are composed of an investing layer of epithelium and of newly formed cellular tissue ; and they originate in the corium, where their points, which, as is well known, are the more unmanageable part, take deep root (Simon). With these most probably we may connect those out-growing tumors which occur in the Pian of tropical climates, and have by many been regarded as syphiloid; as well as various affections that are met with on the coasts of Europe, for instance, the Radesyge, &c. b. Fatty tumors are usually congenital: sometimes only one exists; at other times there are several, which are situated at other parts of the body. They form rounded, globular excrescences, which are, for the most part, truncated and attached by a pedicle, and sometimes grow to a considerable size. They consist of a prolongation of cutis, and enclose some fatty tissue, which seems like a protruded lobule of subcutaneous fat; for at the base or neck of the excrescence it is continuous by a sort of pedicle with the general subcutaneous adipose stratum. The epider- mis covering them is sometimes dark-colored, and pigment (Nasvus lipo- matodes of Walther), and unnatural hair often grows upon them. When it is a congenital disease, it is often associated with naevus in other parts of the skin. In some few cases, these lipomatous growths are developed in later periods of life. c. Fibroid tissue occurs in skin thickened by repeated, or by chronic, attacks of erythema; in the Avheals and knolls of the skin in cases of elephantiasis, &c. It also constitutes cicatrix tissue. d. The growth which Alibert has denominated cheloid may probably be placed in connection with the last named; for it appears to consist of fibroid callus, and Avith that appearance its external cicatrix-like aspect corresponds. There are several varieties of cheloid; it may be a simple hardness or callosity of the skin, either flat, somewhat raised, or de- pressed, and white or pale rosy-colored; or it may be cord-like : in either case it frequently terminates in white or red elevated lines or processes (the spider-like pimple of Warren), and is of considerable extent. It occurs, for the most part, singly at the upper part of the trunk, on the extremities, or on the face ; in very few instances does any large number exist. It very rarely ulcerates ; when it does so, the sore may now and then have a malignant (bosartig) character. Some constitutional disorder lies at the root of every case, but the nature of it is unknown; that it is cancerous is altogether problematical. e. Anomalous bony substance is extremely rare in the skin. I once found, in the substance of a scar on the trunk, an oval, yellowish, hard, rugged, osteoid plate, about the size of a thaler.1 It corresponds pre- cisely with the calcareous growths occurring in fibroid exudations upon serous membranes. /. Teleangiectasis in skin is the well-known vascular nsevus; it is almost always congenital. Sometimes it forms deep-red, or bluish-red, stains of extremely various size and form (Feuermal,—moles), and sometimes red 1 [About the size of an English half crown.—Ed.]
