A special kind is the _cancer colis_ (eating ulcer of the member), probably the same as the νομὴ (spreading ulcer) of the Greeks, which Aëtius[382] delineates as a spreading, flaccid ulcer, which on pressure emits a thin bloody discharge, that subsequently becomes feculent. Hemorrhage is apt to supervene according to Celsus on the shedding of a cicatrix artificially produced by operation or the cauterizing iron. Another species of _cancer_ is the φαγέδαινα (phagedenic, eating ulcer) of the Greeks, which extends rapidly and penetrates to the bladder. It appears to be identical with ἄνθραξ (malignant pustule), though Celsus mentions the _carbunculus colis_ (carbuncle of the member) in a special category; for the description he gives, bk. V. ch. 28., of carbuncle is equally applicable to the phagedaena.[383] Ἄνθραξ (malignant pustule) begins with itching, later on a pustule, or else a number of little bladders or blebs resembling millet-seeds appear, which burst in much the same way as a blister due to burning does, leaving behind an _ulcus crustaceum_ (scab-encrusted ulcer), resembling the cicatrix of a burn; this is firmly adherent and black in colour. The surrounding tissue is likewise black and violently inflamed, the inflammation not unfrequently having an erysipelas-like character. _Galen_[384] designates the process ἀνθράκωσις, and declares that buboes are an accompanying feature. He holds the ulcers of the genitals occurring under the special climatic conditions laid down by Hippocrates above to have been partly ἄνθραξ,[385] the disease to which Hero succumbed. Another kind of ulcer affecting the male genitals is mentioned by _Pollux_[386] under the name of θηρίωμα (malignant sore), which _Celsus_ (V. 28.) likewise speaks of, but without particularizing its situation. The same fact applies to ulcers of the glans penis as to those of the prepuce, viz. that many forms of morbid outgrowths arise from them; in other instances callosities on the edges of the ulcers are built up, leaving behind a callous protuberance, which the Greeks appear to have called ἥλος (a nail), the Romans _clavus_ (a nail).[387] The proper treatment to be followed in each of these special cases is given by Celsus and the Writers he cites.
