Sphynx cats have abnormal hair follicles and keratinization affecting their skin.
research A case of localized follicular hamartoma: an ultrastructural and immunohistochemical study
The hamartoma is an abnormal hair growth with limited development in the upper hair follicle.
research Tight junctions form a barrier in porcine hair follicles
Tight junctions create a barrier in pig hair follicles that controls what can enter the skin.
research The evolution of healthy skin to acne lesions: a longitudinal, in vivo evaluation with reflectance confocal microscopy and optical coherence tomography
Acne lesions start with changes in hair follicles and increase in inflammation, suggesting a cycle that could affect treatment strategies.
research Chloracne: histopathologic findings in one case
Tiny infundibular cysts are the main lesions in chloracne, not comedones.
research Increasing the percutaneous absorption and follicular penetration of retinal by topical application of proretinal nanoparticles
Proretinal nanoparticles improve skin absorption and reduce irritation of topical retinoids.

The 14-3-3σ gene is essential for preventing hair loss.
research Preliminary findings suggest hidradenitis suppurativa may be due to defective follicular support
Hidradenitis suppurativa is likely caused by blocked hair follicles, not apocrine glands.
research Controversial Concepts
The author now believes tricholemmal carcinoma is a rare type of infundibular squamous cell carcinoma and more research is needed on these tumors.
research Pathologic Quiz Case: An 84-Year-Old Woman With a Skin Cyst Containing Ziehl-Neelsen–Positive Structures
Basal cell carcinoma may originate from vellus hair cysts.

LC-OCT is an effective new method for diagnosing classic lichen planopilaris.
research Perifollicular inflammation and follicular spongiosis in androgenetic alopecia
Hair loss in both Androgenetic Alopecia and Alopecia Areata is often accompanied by inflammation around hair follicles, but the location and severity of this inflammation varies.
research Histopathologic Criteria for Follicular Differentiation
The document outlines criteria to identify and differentiate neoplasms based on follicular characteristics.
research Viewpoint 4
