The general name θύμος (_thymus_,—warty excrescence), or according to Celsus perhaps more correctly θύμιον (small warty excrescence), appears to have been used by the Greeks to designate all morbid outgrowths, and particularly those of the genitals and fundament, while they appropriated the expressions σῦκος, ἀκροχορδὸν, and μυρμήκια (fig or figlike excrescence, wart with a neck, wart growing directly on the skin) to signify the different subordinate species. The θύμιον, which _Celsus_[430] is the first Writer to delineate in detail, is a warty, reddish,—according to Paulus Aegineta white too in some cases, and as a rule painless,—fleshy outgrowth, slender at the base, broader above, rather hard and rough at the top. Thus it bears a certain resemblance to the flower of the thyme, from which circumstance comes the name. The upper part is easily split, and then bleeds,—more than might be expected Aëtius says from its size; the same also sometimes happens spontaneously. Usually it has the size of an Egyptian bean, though occasionally it is quite small. Sometimes one such growth appears, at others several are found together, now on the palms of the hands, now on the soles of the feet; but the worst are always those on the genital organs. According to _Aëtius_, who calls the larger sorts σῦκος (fig), _thymus_ is also found on the fundament and on the face, in women on the _labia_, in the entrance to the vagina and in the vagina itself, spreading thence to the fundament and even over the thighs. This is confirmed by _Oribasius_, who as well as Paulus Aegineta and perhaps Celsus, distinguishes a _malignant_ and a _non-malignant_ form. The non-malignant growths generally disappear of themselves; but if they are amputated, there remains behind, so says Celsus, a circular root which penetrates deep into the flesh; and not only do they grow again, but further take the character of the malignant form, become painful and filled with a bloody ichor. The malignant show themselves both with and without ulceration, as well as after the disappearance of the non-malignant growth; they are harder, rougher and larger, have a dirty livid hue, and are painful, particularly on being touched. Thymus on the glans penis is more dangerous than when affecting the prepuce,[431] more especially if it assume a carcinomatous character. If of the non-malignant type it should be lightly scarified with the point of a scalpel, then some mild escharotic employed, for which the Writer just named gives several prescriptions. If of the malignant type, it is according to Paulus Aegineta either tied with a horse-hair and then removed by knife or cautery, or according to what Oribasius says the latter is at once resorted to. But seeing thymus on the prepuce is often found affecting the inner and outer surfaces simultaneously, cautery must not be employed on both at once, for in that way the foreskin would be destroyed altogether. The better plan is to begin
