January 2011 in “American Journal of Dermatopathology” This study investigated pilomatrixoma, a benign skin tumor, and found that irregular expression of β-catenin and Lef-1 in transitional cells may contribute to amorphous debris and cyst formation.

May 2001 in “British Journal of Dermatology” This study suggests that pilomatrixomas' maturation towards areas of shadow cells is linked to a gradual loss of differentiation-specific hair keratins, supporting a hair matrix origin for the tumor.

,
December 2005 in “Journal of Cutaneous Pathology” This study found that while malignant pilomatricomas maintain some keratin expression patterns seen in benign counterparts, they notably express additional epithelial keratins, potentially influencing tumor calcification.
54 citations
,
September 1999 in “PubMed” This study suggests that immunostaining for Keratin 15 may be a useful tool for differentiating between basal cell carcinoma and trichoepithelioma.

,
December 2015 in “International Journal of Dermatology” This study suggests that basal cell carcinoma and trichoblastoma may share differentiation toward the hair follicle, as indicated by strong positivity in CK 15, follistatin, and Bmi‐1 markers.

March 2009 in “Experimental Dermatology” This study suggests that pilomatricoma can differentiate towards various hair follicle structures, including hair matrix, hair cortex, follicular infundibulum, outer root sheath, and hair bulge.
