Perivascular epithelioid cell tumour
In oncology, PEComa, also PEC tumour and perivascular epithelioid cell tumour, is a family of mesenchymal tumours consisting of perivascular epithelioid cells (PECs). These are rare tumours that can occur in any part of the human body.
The cell type from which these tumours originate remains unknown. Normally, no perivascular epitheloid cells exist; the name refers to the characteristics of the tumour when examined under the microscope.
Establishing the malignant potential of these tumours remains challenging although criteria have been suggested; some PEComas display malignant features whereas others can cautiously be labeled as having 'uncertain malignant potential'. The most common tumours in the PEComa family are renal angiomyolipoma and pulmonary lymphangioleiomyomatosis, both of which are more common in patients with tuberous sclerosis complex. The genes responsible for this multi-system genetic disease have also been implicated in other PEComas.
Many PEComa types shows a female predominance in the sex ratio.

Become You
by: Indigo GirlsI heard you sing a rebel song,
sung it loud and all alone.
We can't afford the things you save,
we can't afford the warranty.
I see you walking in the glare
down the county road we share.
Our southern blood, my heresy,
damn that ol' confederacy.
It took a long time to
become the thing I am to you.
And you won't tear it apart
without a fight, without a heart.
I'm sorry for what you have learned,
when you feel the tables turn.
To run so hard in your race,
now you find who set the pace.
The landed aristocracy
exploiting all your enmity.
All your daddies fought in vain,
leave you with the mark of Cain.
It took a long time to
become the thing I am to you.
And you won't tear it apart
without a fight, without a heart.
It took a long time to
become you, become you.
The center holds, so they say.
It never held too well for me.
I won't stop short for common ground
that vilifies the trodden down.
The center held the bonded slave
for the sake of industry.
The center held the bloody hand
of the executioner man.
It took a long time to
become the thing I am to you.
And you won't tear it apart
without a fight, without a heart.
It took a long time to
