A woman's small ovarian tumor causing high androgen levels was missed by several scans but found during surgery.
research Effect of beta--catenin on regulating hair follicle cells' proliferation
Beta-catenin boosts hair follicle cell growth by increasing c-myc expression.

Trichogerminoma is a rare, benign skin tumor from hair cells, with a small risk of becoming cancerous.
research Cornification in reptilian epidermis occurs through the deposition of keratin‐associated beta‐proteins (beta‐keratins) onto a scaffold of intermediate filament keratins
Reptile skin hardens by layering beta-proteins on keratin.
research Niosomal versus cubosomal gels of cetirizine hydrochloride: Cost-effective permeation enhancement for potential transdermal application

research Rippled‐pattern trichomatricoma
A unique hair tumor with a rippled pattern was identified, showing incomplete differentiation and unusual cell arrangements.
research Ductal breast cancer in a male patient
An 86-year-old man with prostate cancer was diagnosed with a rare, low-grade breast cancer and underwent surgery but declined additional hormone therapy.
research Sebocytes are the Key Regulators of Androgen Homeostasis in Human Skin
Sebocytes play a key role in controlling androgen levels in human skin.
