蒋示吉曰∶初生小儿头上胸乳间肿起，大如馒首，小似李梅，此乃胎中瘀血凝滞
而成。须候小儿盈月以外，方可用针刺破，内如赤豆汁乃安。内服五福化毒丹。（《说约》）
《心法》曰∶胎瘤乃胎前孕妇积热，以致胞热，更兼血瘀结滞而成。多生头上及
胸乳间，初如李核，渐大如馒，色紫微硬，漫肿不甚疼痛。如婴儿初生即有者，候过
盈月，熟透方可针之，放出赤豆汁或脓汁，其肿即消。若盈月后生者，必待脓鼓熟透
再针。
吴半千曰∶红丝瘤一名胎瘤，发无定处，由小渐大，婴儿落草，或一二岁之间
患之，瘤皮色红中含血丝，亦有自破者。治法虽同胎瘤，但此患由先天肾中伏火，精
有血丝，以气相传生子，故有此疾。终为火证，亦难收敛。
陈实功曰∶儿在胎中，母食五辛，喜飧炙 ，遗热与儿，生后头面遍身发为奶
癣，流脂成片，睡卧不安，搔痒不绝，治以文蛤散。（《正宗》）
吴半千曰∶小儿初生奶癣，类乎疥癞。初起手足，次延腹背，缠绵不已。用僵蚕
不拘多少，去嘴研末，煎汤浴之，或一日一次，毒必发生，然后用青黛散搓之。
《心法》曰∶此证初生头顶，或生眉端，痒起白屑，形如疥癣，由胎中血热，落草
受风缠绵，此即干 疮。有误用汤火洗皮肤起粟，搔痒无度，黄水津淫，延及遍身，
即成湿 疮。干用润肌膏，湿用黄柏头末，滑石和匀干掺，痒甚者用乌云膏。
蒋示吉说：新生儿头部、胸部和乳房之间肿起，大的像馒头，小的像李子或梅子，这是胎儿时期瘀血凝滞所形成的。必须等到婴儿满月以后，才可以用针刺破，如果流出像赤豆汁一样的液体，病情才会安定。内服五福化毒丹。（出自《医宗说约》）
《医宗心法》说：胎瘤是由于孕妇在怀孕期间积热，导致胞宫发热，再加上血液瘀结停滞而形成的。多生长在头部及胸乳之间，起初像李核，逐渐变大像馒头，颜色紫暗且微硬，漫肿但不太疼痛。如果是婴儿出生时就有的，要等过了满月，肿块熟透后方可针刺，放出赤豆汁或脓汁，肿胀就会消退。如果是满月后才生的，必须等待脓包鼓胀熟透后再针刺。
吴半千说：红丝瘤又名胎瘤，发作没有固定位置，由小逐渐变大，婴儿出生后，或者在一两岁之间患病，瘤体皮肤呈红色，里面含有血丝，也有自行破裂的。治疗方法虽然与胎瘤相同，但这种病是由先天肾中潜伏的火邪，精气中带有血丝，通过气息遗传给儿子，所以有此疾病。最终属于火证，也难以收敛愈合。
陈实功说：胎儿在母体内时，母亲食用五种辛辣食物（五辛），喜欢吃烧烤炙烤之物，将余热遗留给婴儿，出生后头面及全身发出奶癣，流脂成片，睡眠卧躺不安稳，瘙痒不止，用文蛤散治疗。（出自《外科正宗》）
吴半千说：小儿初生时的奶癣，类似于疥疮和癞疾。起初发于手足，随后蔓延至腹部和背部，缠绵难愈。使用僵蚕不拘数量，去掉嘴部后研成粉末，煎汤洗澡，或者一天洗一次，使毒素发散出来，然后用青黛散搓擦患处。
《医宗心法》说：此症初生时在头顶，或者生在眉毛边缘，瘙痒并起白屑，形状像疥癣，是由于胎中血热，出生后受风邪侵袭而缠绵不愈，这就是干性奶癣（干癣）。如果有误用热水或火烤清洗皮肤，导致皮肤起粟粒状疹子，瘙痒无度，黄水渗出浸淫，蔓延至全身，就变成湿性奶癣（湿癣）。干性的用润肌膏，湿性的用黄柏末、滑石粉混合均匀干撒，瘙痒严重的用乌云膏。
Jiang Shiji stated: Swellings arise on the head, chest, and breasts of newborn infants, large as steamed buns or small as plums and medlars. This is caused by the stagnation of fetal blood stasis (blood stasis formed during gestation). One must wait until the infant is past one month old before puncturing with a needle; if fluid resembling red bean juice is discharged, the condition will stabilize. Internally administer Wufu Huadu Dan (Five Blessings Toxin-Resolving Pill) [Source: *Yizong Yueyue*].
*Yizong Xinfa* states: Fetal tumors are caused by accumulated heat in the pregnant mother, leading to heat in the uterus (womb), compounded by blood stasis and stagnation. They mostly occur on the head and between the chest and breasts. Initially like a plum pit, they gradually enlarge to the size of a steamed bun, appearing purplish and slightly hard, with diffuse swelling but little pain. If present at birth, wait until after one month when the lesion is ripe before puncturing to discharge red bean-like fluid or pus, after which the swelling subsides. If arising after one month, one must wait for the abscess to become fully distended and ripe before puncturing.
Wu Bankian stated: Red-threaded tumors, also known as fetal tumors, have no fixed location and grow gradually from small to large. Infants may suffer from this shortly after birth or between one and two years of age. The tumor skin is red with visible blood threads inside, and some cases rupture spontaneously. Although the treatment method is similar to that for fetal tumors, this disease stems from latent fire in the congenital Kidney (Shen organ), where essence contains blood threads transmitted via Qi to the offspring, resulting in this ailment. Ultimately, it is a Fire syndrome and difficult to heal/converge.
Chen Shigong stated: While in the womb, if the mother consumes the "Five Pungents" (five pungent vegetables/herbs) and favors roasted/grilled foods, residual heat is passed to the infant. After birth, milk eczema appears all over the head, face, and body, oozing lipid in patches, causing restlessness during sleep and incessant itching. Treat with Wen Ge San [Source: *Waike Zhengzong*].
Wu Bankian stated: Milk eczema in newborns resembles scabies and leprosy. It begins on the hands and feet, then spreads to the abdomen and back, lingering persistently. Use Silkworm (Bombyx Batryticatus) in any quantity, remove the head, grind into powder, and decoct for bathing. Bathe once daily to allow toxins to emerge, then rub Qingdai San (Indigo Naturalis Powder) onto the affected area.
*Yizong Xinfa* states: This condition initially appears on the crown of the head or at the eyebrows, presenting with itching, white scales, and a shape resembling scabies or tinea. It is caused by fetal blood heat and wind invasion after birth, leading to chronic persistence; this is dry eczema (dry tinea). If mistakenly washed with hot water or exposed to fire, causing millet-like papules on the skin, extreme itching, and weeping yellow fluid spreading over the body, it becomes wet eczema (wet tinea). For dry types, apply Runji Gao (Moisturizing Muscle Ointment); for wet types, sprinkle a mixture of Huangbai End (Phellodendron Bark) and Talcum (Hua Shi) evenly; for severe itching, use Wuyun Gao (Dark Cloud Ointment).
