cytokeratin trichoblastic fibroma trichoepithelioma basal cell carcinoma CK7 immunostaining skin

Studysummary This study found that trichoblastic fibroma and basal cell carcinoma cannot be differentiated by cytokeratin expression patterns, while trichoepithelioma lacks CK7 expression, distinguishing it from the other two neoplasms.

8 / 8 results

research Immunohistochemical Localization of Cytokeratins and Involucrin in Calcifying Epithelioma: Comparative Studies with Normal Skin

49 citations , July 2006 in “British Journal of Dermatology”

This study observed that calcifying epithelioma of Malherbe is composed of tumor cells that differentiate into both hair cortex and outer root sheath, supporting its hair follicle origin.

research Keratinocyte Differentiation in Psoriatic Scalp: Morphology and Expression of Epithelial Keratins

63 citations , July 2006 in “British Journal of Dermatology”

This study found that keratin K17 is induced in the suprabasal layer of psoriatic scalp epidermis during epidermal hyperproliferation, suggesting it is not specific to hair follicles.

research Keratin Expression in Basal Cell Carcinomas

128 citations , February 1992 in “British Journal of Dermatology”

The researchers reported that basal cell carcinoma tumor cells strongly express keratins typical of basal keratinocytes and some hair follicle components but lack differentiation markers, suggesting a follicular or pluripotent stem cell origin.

research Immunohistochemical Demonstration of Keratins 8 and 14 in Benign Tumors of the Skin Appendage

38 citations , November 1991 in “Archiv für Pathologische Anatomie und Physiologie und für Klinische Medicin”

Keratins 8 and 14 can help identify and diagnose benign skin tumors.

research Keratin 19: Predicted Amino Acid Sequence and Broad Tissue Distribution Suggest It Evolved from Keratinocyte Keratins

research Keratins of the Human Hair Follicle: Hyperproliferative Keratins Consistently Expressed in Outer Root Sheath Cells In Vivo and In Vitro

135 citations , November 1987 in “Differentiation”

This study found that cultured outer root sheath cells from human hair follicles expressed a keratin profile similar to their in vivo environment, indicating environmental influence on keratin expression.

research Generalized Trichoepitheliomas With Alopecia and Myasthenia Gravis: Clinicopathologic and Immunohistochemical Study and Comparison With Classic and Desmoplastic Trichoepithelioma

54 citations , November 1986 in “Journal of the American Academy of Dermatology”

This case report identifies a potential new syndrome characterized by trichoepitheliomas and alopecia, which may be associated with myasthenia gravis.

research Different Keratin Polypeptides in Epidermis and Other Epithelia of Human Skin: A Specific Cytokeratin of Molecular Weight 46,000 in Epithelia of the Pilosebaceous Tract and Basal Cell Epitheliomas

277 citations , October 1982 in “The Journal of Cell Biology”

This study found that the cytokeratin patterns in skin epithelia can distinguish between different types, with basal-cell epitheliomas showing a striking similarity to the pilosebaceous tract.
