    by granulation cells, in diffused instead of nodular masses, slightly elevated as a rule, with sharply denned borders, and flattish sur- face When of inflammatory origin, the colour is usually red, or brownish red, but small tumours may be of any colour. Their size, shape, colour, consistency and course, are the points to be specially noticed. Tumores. Synonyms.—Tumours; Fr., Tumeurs ; Gen, Knollen. Definition.-^ growths of all kinds, from a pea and upwards in size. There is no limit to the size of tumours in an upward direction. The shape also is equally variable, though, unless compound, they are generally roundish. They are generally, but not always, well defined ; may be sessile or pedunculated, with broad or narrow attachments. They are raised to a very variable extent, with superficial or deep attachments, movable with the skin, or fixed to deeper parts ; and may, or may not, be attended with itching, tenderness, or pain. _ _ Their causes are very various. As they may take their origin from any part of the skin, its vessels or appendages, the colour of the skin may or may not be altered. The chief points to be observed are, the size, shape, colour, elevation, vascularity, mode and depth of attachment, movability, subjective symptoms, and, where possible, the part of the skin in which they originate. Vesiculae. Synonyms.—Vesicles ; Fr., Vesicules ; Ger., Blaschen. Definition.—Vesicles are elevations above the surface of the skin, from a pin's head to a hemp seed in size, with free contents of serous fluid. Vesicles are produced by elevations of the upper layers of the epidermis by fluid, which may be forced upwards from below, either by mechanical or inflammatory pressure. They may arise directly on the surface, as in miliaria ; or on the top of an inflam- matory base, diffuse or papular, as in eczema. Their contents may be clear, turbid, or more or less blood-stained. They are generally tense, but the large ones may be flaccid; most of them rupture, as in eczema, but in many the contents are either absorbed or dry up without rupturing, as in sudamina or herpes.
