Pilomatricoma can develop into various hair-related structures.
research Clinicopathologic and molecular characterization of a series of sporadic trichoblastic neoplasms
Sporadic trichoblastic neoplasms generally don't recur or spread, with one case showing a specific genetic fusion.
research Eccrine angiomatous hamartoma
The girl's skin condition is benign but challenging to treat due to its size and location.
research Monilethrix: Mutational Hotspot in the Helix Termination Motif of the Human Hair Basic Keratin 6
Monilethrix severity varies and may be influenced by other genetic or environmental factors.
research Insertional mutation of the hairless locus on mouse Chromosome 14
A gene mutation in mice causes permanent hair loss and skin issues.
research Keratin gene mutations in disorders of human skin and its appendages
