research 311 Single-cell transcriptomics reveals distinct molecular programs in folliculotropic mycosis fungoides
Folliculotropic mycosis fungoides has unique molecular features and cell interactions that could guide targeted therapy.
research Studies on equine eosinophilic granuloma and mast cell tumour
Equine eosinophilic granuloma is the most common skin disease in horses, while mast cell tumors are less common and differ in their cellular makeup.
research Urticaria Neonatorum: Accumulation of tryptase‐expressing mast cells in the skin lesions of newborns with Erythema Toxicum
Newborns with the common rash Erythema Toxicum have many active mast cells in their skin, but these cells don't produce the LL-37 peptide.
research Acneiform follicular mucinosis
Acneiform follicular mucinosis can be controlled with systemic corticosteroids.
research Panfolliculoma: report of two cases
Panfolliculoma is a rare, non-cancerous growth related to hair follicles.
research Compound Follicles in Folliculitis Decalvans Do Not Contain Vellus and Retained Telogen Follicles—A Pilot Histopathologic Series on Polytrichia
Compound follicles in folliculitis decalvans mainly have active hair follicles.
research Eosinophils in fibrous tracts and near hair bulbs: A helpful diagnostic feature of alopecia areata
Eosinophils are not a reliable marker for diagnosing alopecia areata.
research Stress-induced chemokine production by hair follicles recruits dendritic cells to sites of minor trauma
Hair follicles help attract immune cells to minor skin injuries.

Lipid-antigen stimulation may play a role in folliculotropic mycosis fungoides.
research Mucin‐poor follicular mycosis fungoides
The patient's symptoms improved with treatment but recurred when the steroid dose was reduced, requiring ongoing therapy.
research Cystic panfolliculoma of the conchal bowl
Cystic panfolliculoma is a rare, harmless tumor that can be confused with other skin tumors.
research Ultrastructure of Follicular Mucinosis
Follicular mucinosis causes significant damage to hair follicle cells.
research 85 Primary cutaneous follicle center lymphoma spans yet unrecognised subtypes including polyclonal reactions
PCFCL may have unrecognized subtypes and needs more research.
research Follicular mycosis fungoides mimicking a cutaneous B‐cell lymphoproliferative disorder
Follicular mycosis fungoides can look like a B-cell lymphoma, making diagnosis difficult.
research Differential expression of stem cell markers in human follicular bulge and interfollicular epidermal compartments
Different markers are found in stem cells of the scalp's hair follicle bulge and the surrounding skin.
research 1323 Human dermal fibroblasts and mast cell populations are altered in hidradenitis suppurativa, with epithelial-mesenchymal-transition signals ameliorated by spleen tyrosine kinase antagonism.
Skin cells and immune cells change in a skin condition called hidradenitis suppurativa, and a certain treatment can improve these changes.
research 036 Expanded T cells under lymphopenic condition exhibit memory phenotype and infiltrate around hair follicle
T cells with memory features grow in number and gather around hair follicles when there are not enough immune cells.
research Expression of melanocortin receptors on cutaneous fibroblastic cells – collagen and beyond
MC-1R in skin cells may influence inflammation and collagen production.
research The clinical features and histopathologic patterns of folliculotropic mycosis fungoides in a series of 38 cases
Recognizing diverse presentations of folliculotropic mycosis fungoides is crucial to avoid diagnostic errors.
research Hair Matrix Cyst
Hair matrix cysts are rare skin nodules with unique features, often needing surgical removal.
research The Arrector Pili Muscle and the Follicular Unit of the Scalp: A Microscopic Anatomy Study
The study found that hair follicles are above muscle connections in the scalp, which may help protect stem cell areas.
research Tufted hair folliculitis developing in a recalcitrant lesion of pemphigus vulgaris
Scalp inflammation can cause multiple hairs to grow from one follicle.
research Clinicopathologic study of 90 cases of trichofolliculoma
Trichofolliculoma is a unique benign tumor mainly affecting middle-aged adults' faces, often misdiagnosed without histopathology.
research Differential diagnoses of pseudolymphomatous folliculitis: considerations as regards one case
