GlossaryMucin Deposition

accumulation of gel-like mucin within tissues

Mucin deposition refers to the accumulation of mucin, a gel-like substance produced by epithelial cells, within tissues. In the context of hair and skin, excessive mucin deposition can occur in conditions like alopecia mucinosa, where it disrupts normal hair follicle function and leads to hair loss. This process can be identified through histological examination, where mucin appears as a clear, amorphous material within the dermis.

community If You Have DUPA, PLEASE READ THIS: Everyone Should Be Scalp Biopsied

in Research 830 upvotes 1 year ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
