Punctate follicular porokeratosis is a skin condition with specific features seen in hair follicles.
research Trichofolliculoma in a Family – An Unusual Occurrence
A rare family case of multiple benign hair follicle tumors was identified, highlighting the need to distinguish them from similar conditions.
research Avaliação quantitativa em cortes histológicos transversais do couro cabeludo
The study found average numbers for different types of hair follicles in the scalp and observed differences between men and women, suggesting reasons for more common hair shedding in women.
research Immunohistochemical dissection of cystic panfolliculoma focusing on the expression of multiple hair follicle lineage markers with an insight into the pathogenesis
Cystic panfolliculoma resembles hair follicle tumors due to specific cell interactions.
research Dynamic ultrastructural changes of the connective tissue sheath of human hair follicles during hair cycle
The connective tissue around hair follicles changes structure throughout the hair cycle.
research The Arrector Pili Muscle and the Follicular Unit of the Scalp
Each group of hair follicles on the scalp shares one muscle that helps control hair movement.
research Hair sheath keratins in follicular tumors. (5). Identification of hair sheath keratins in keratoacanthoma; Histopathological hair sheath structures in the tumor and their significance as differential histopathological criteria from squamous cell carcinoma.
