June 2009 in “Mammalian genome” This study describes a mouse model for Marie Unna Hereditary Hypotrichosis, identifying mutations in the hairless gene that result in sparse or absent hair and cyst-like hair follicles.
April 2024 in “bioRxiv (Cold Spring Harbor Laboratory)” In a keratinocyte-specific knockout mouse model, this study found that deleting GRK2 disrupted hair follicle homeostasis, causing cyst-like structures, abnormal growth patterns, and eventual hair loss, suggesting potential links to immune-mediated alopecias.
July 2025 in “JOURNAL OF CLINICAL AND DIAGNOSTIC RESEARCH” In this case report, a nine-year-old boy with an unusual scalp nodule was found to have trichofolliculoma, a rare skin tumor, emphasizing the importance of considering this diagnosis in children and using dermoscopy and histopathology for accurate identification and treatment.

September 2019 in “The journal of investigative dermatology/Journal of investigative dermatology” This study identified a distinct CD49fhigh mesenchymal stem cell subpopulation in the dermis that supports hair follicle development and maintenance via Notch signaling activation.
February 2022 in “Skin research and technology” This study found that skin computed tomography may effectively identify epidermoid cysts by revealing features consistent with histopathology, potentially serving as a non-invasive diagnostic alternative to biopsies.
