Knit Me a Teratoma

Call me an old-fashioned granny, but I do love knitting. I’m not very good (getting better), and what I can knit is limited to hats, mittens, scarves, and the obligatory pot holder. So I think that knitting this complicated and grotesque teratoma is still a bit beyond my skill level……wait!?! A teratoma…..knitted?! Yes, its true, and if you start now, it may be finished by Halloween.


Is that a teratoma or are you just happy to see me?

The word teratoma roughly means “monstrous tumor,” and is a germ cell tumor which has some mature differentiated tissue types which are usually very out-of-place, and occasionally teeth, jaws, eyeballs and hands. They are an interesting and rare medical oddity. I won’t include any pictures (they’re a bit gross), but you can do an image search on ‘teratoma’ if you’d like to learn more about them.

    Wow, so a teratoma is a kind of hideous pinata. Who knew?

    Don’t worry – there’s nothing wrong with being old-fashioned.

    P.S. Are you ever going to link to my new blog?

    Hello Shelley,

    Maybe you can write on the cognitive neuroscience of knitting…there must be a reason why so many adult women (plus you) get hooked to it!

    Best argument in favor of taking up knitting I’ve ever heard.

    Wow…that is the most awesome thing ever! I’ve had a teratoma myself (very large ovarian cysts, had surgery to remove them,lost an ovary in the process, they discovered one of the cysts was a teratoma) …didn’t know they were that rare. I might just have to make this to commemorate the occasion. 😛
