When these are likely to result from a too rapid closure of the edges of the scrotal envelope, the premature union may be readily prevented, as we have before stated, by the careful introduction of the finger into the wound while it is still suppurating. But notwithstanding this precaution they will sometimes occur as the result of the infiltration and accumulation of the suppurative matter. A free incision and proper attention to the cavity of the abscess, is all that this accident requires. A careful examination of the parts will, however, reveal another cause for the formation of these abscesses. It is then against these causes that the therapeutic treatment must be directed. We refer now to the complication known as the formation of a CHAMPIGNON. This name is applied to an indurated condition of the end of the cord, or in its thickness, of a tumefied character, varying in size and extent, and slow in its growth. It results from an excess of inflammatory action, attributable to the manipulations which become necessary during the performance of the operation. The name “champignon” (or mushroom) is applied to it by the French, on account of the pedunculated appearance which it sometimes assumes, and which causes it to greatly resemble that fungus in its outward figure. It is also known as schirrous or indurated cord. The tumor is sometimes situated on the outside of the envelopes, when it is known as _extra-scrotal_, but more commonly it is found covered by the skin, in which case it is better known as _intra-scrotal_. In this latter condition it may be merely a growth at the end of the cord, becoming, as determined by its location, of an _extra-inguinal_ character, or if the diseased process extends as far as the upper inguinal opening, or beyond it, it becomes, and is so denominated, _intra-abdominal_. There is also an _extra-intra-scrotal_ growth, when it is partly within and partly external to the scrotum. This tumor will vary greatly in size, being sometimes very small in dimensions, and at others having those of a man’s fist. We have ourselves observed it equalling a child’s head in size.
