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 Loss of Gata6 causes dilation of the hair follicle canal and sebaceous duct
Removing Gata6 causes hair follicle and sebaceous duct enlargement.

Proretinal nanoparticles improve skin absorption and reduce irritation of topical retinoids.
research Eruptive Vellus Hair Cysts: Report of a New Case with Immunohistochemical Study and Literature Review
Eruptive vellus hair cysts are rare, benign skin lesions that are hard to treat.
research Cutaneous Adnexal Cysts Revisited: What We Know and What We Think We Know

research 14-3-3σ Is Required for Club Hair Retention
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 Preparing the hair follicle canal for hair shaft emergence
A specific type of skin cell creates an opening for hair to grow out, and problems with this process can lead to skin conditions.
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.
research D2-40 Expression in Primary Scarring and Nonscarring Alopecia
Most people with scarring and nonscarring hair loss show similar D2-40 levels, but some with scarring hair loss have higher levels.
research Line‐field confocal optical coherence tomography: A new diagnostic method of lichen planopilaris
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 Cutaneous Hybrid Cyst in a Sprague-Dawley Rat
A rat had a cyst similar to a hair follicle structure.
