Teratoma with teeth. (A. Deblauwe)

If it weren't for the careful eyes of an excavator, working at an ancient
underground tomb in Egypt, archaeologists may never have found it: a lonely
tooth, nestled in the curve of a worn-down pelvis.

At first, site supervisor and archaeologist Melinda King Wetzel thought she
was looking at a fetus from the time of the Egyptian pharaohs.

But when she showed the grave to the bioarchaeological director of the site,
Gretchen Dabbs, the discovery turned out to be even rarer in nature.

Along with another site supervisor, Anna Stevens, Wetzel and Dabbs claim to
have found the oldest evidence of a mature ovarian teratoma, or germ cell
tumor.

Today, the mass looks like a calcified clump of disorganized and fully formed
tissues, like bone and teeth.

It measures roughly 3 by 2 centimeters (0.8 by 1.2 inches) in dimension and
dates back to the mid-14th century BCE.

如果不是挖土機在埃及一座古老的地下墓穴中工作時的細心觀察，考古學家可能永遠找不
到它：一顆孤獨的牙齒，坐落在磨損的骨盆的曲線中。

起初，現場主管兼考古學家梅琳達· 金· 韋策爾認為她看到的是埃及法老時代的胎兒。

但當她向該遺址的生物考古主任格雷琴· 達布斯(Gretchen Dabbs)展示這座墳墓時，發現
這項發現在自然界中更為罕見。

安娜· 史蒂文斯、韋策爾和達布斯與另一位現場主管一起聲稱發現了成熟卵巢畸胎瘤或生
殖細胞腫瘤的最古老證據。

如今，腫塊看起來像是一團鈣化的雜亂且完全形成的組織，如骨骼和牙齒。

它的尺寸約為 3 x 2 公分（0.8 x 1.2 英寸），其歷史可追溯至公元前 14 世紀中葉。

Researchers say it adds "considerable temporal and geographical depth to our
understanding of this condition in the past."

Wetzel, Dabbs, and Stevens, who all hail from different companies and
universities, have been working together at this archaeological site, on the
eastern banks of the Nile River, for years now, as part of the Amarna Project.

This is a long-term, ongoing dig that seeks to uncover the cemeteries of
normal folk buried near what was once the capital city of the Pharaoh
Akhenaten, established from 1345 BCE.

The young female skeleton with the ovarian tumor was found buried in a
multi-chambered tomb at Amarna's North Desert Cemetery and was probably 18 to
21 years of age when she died.

She was buried with her hands positioned over her pelvis and wrapped in a way
that was common for other non-elite Amarna cemeteries. That said, she had
more jewelry on her than other bodies nearby.

Within the ring of her pelvic bone, however, lay a different sort of jewel.

研究人員表示，它「大大增加了我們對過去這種情況的理解的時間和地理深度」。

韋策爾、達布斯和史蒂文斯來自不同的公司和大學，作為阿瑪納計畫的一部分，他們多年
來一直在尼羅河東岸的這個考古遺址一起工作。

這是一項長期持續的挖掘工作，旨在發掘埋藏在公元前 1345 年法老阿肯那頓首都附近的
普通民眾墓地。

這具患有卵巢腫瘤的年輕女性骨架被發現埋在阿瑪納北部沙漠公墓的一個多室墓穴中，她
去世時可能年齡在 18 至 21 歲之間。

她下葬時雙手放在骨盆上，並以其他非精英阿瑪納墓地常見的方式包裹。也就是說，她身
上的珠寶比附近其他屍體都多。

然而，在她的骨盆內，卻鑲嵌著一種不同類型的寶石。

pelvic bone. (M. Wetzel)

Teratomas are rare types of germ cell tumors that are usually benign,
although they can come with symptoms such as abdominal pain or infertility.

They are very rarely found in archaeology. In fact, this is only the fifth
case of its kind to be uncovered by archaeologists and the only one from
Egypt.

The tumor is several centuries older than the other ancient teratomas
previously discovered by archaeologists in Spain, France, Peru and Portugal.

Initially, when Wetzel saw the tooth, she thought it was alone. But upon
closer inspection, she and her colleagues noticed another empty slot on the
calcified mass.

Further excavations around the female skeleton revealed a second tooth near
the top of the leg bone, still within the pelvic cavity. It fit into the
empty slot nicely, which led archaeologists to conclude that this second
tooth used to be part of the tumor but had separated during decomposition.

畸胎瘤是罕見的生殖細胞腫瘤，通常是良性的，儘管它們可能會出現腹痛或不孕症等症狀
。

它們在考古學中很少見。事實上，這只是考古學家發現的第五起此類案件，也是埃及唯一
一起此類案件。

這種腫瘤比西班牙、法國、秘魯和葡萄牙考古學家先前發現的其他古代畸胎瘤早幾個世紀
。

最初，當韋策爾看到這顆牙齒時，她以為它是單獨的。但經過仔細檢查，她和她的同事發
現鈣化腫塊上還有另一個空槽。

Deblauwe)

Both teeth are covered in full, "if somewhat disfigured", enamel crowns,
according to the authors. They also show partially formed root structures at
their cemento-enamel base.

This is much too developed for an early stage fetus and it strongly suggests
the mass is not an unborn offspring but a tumor.

"Without the careful excavation and recording of the teratoma in situ,"
writes the team of archaeologists, "it is more than likely the isolated tooth
would have been, at least initially, identified as an intrusive element from
a different individual or possibly as evidence of an additional burial within
the tomb if the tooth was not able to be associated with the other
individuals buried in the same tomb."

This particular individual, the researchers say, had a gold ring on her left
hand that sat close to the tumor. It was illustrated with an image of Bes, an
ancient Egyptian deity associated with fertility and protection.

While just a hypothesis, the authors say it is conceivable that this ring
position was purposeful and that the Bes ring might have been used to address
the pain felt in this part of the body or "perceived issues of infertility".

The study was published in the International Journal of Paleopathology.

據作者稱，兩顆牙齒都被完整的牙釉質牙冠覆蓋，“雖然有些變形” 。它們在牙骨質琺
瑯質基底處也顯示出部分形成的根部結構。

對於早期胎兒來說，這太發達了，這強烈表明該腫塊不是未出生的後代，而是腫瘤。



研究人員說，這個人的左手上有一枚金戒指，靠近腫瘤。它的插圖是貝斯的圖像，貝斯是
古埃及與生育和保護有關的神。

雖然這只是一個假設，但作者表示，可以想像，這個環的位置是有目的的，並且 Bes 環
可能被用來解決身體這個部位感受到的疼痛或「感知到的不孕問題」。

這項研究發表在《國際古病理學雜誌》。
