There is no single malady which causes supplementary psychic disturbance and more general insecurity and feeling of inferiority than acne vulgaris with post inflammatory acne pigmentation marks does. It is strongly associated with depression and anxiety. In addition to individuals with little objective evidence acne with post inflammatory acne hyperpigmentation marks may endure severe subjectiv...
Postinflammatory hyperpigmentation is a common sequelae of inflammatory dermatoses that tends to affect darker skinned patients with greater frequency and severity. Epidemiological studies show that dyschromias, including postinflammatory hyperpigmentation, are among the most common reasons darker racial/ethnic groups seek the care of a dermatologist. The treatment of postinflammatory hyperpigm...
Background. Patients on chronic minocycline suppression for orthopedic infections at a single institution were studied for development of minocycline-induced cutaneous hyperpigmentation and analysis of risk factors. Methods. This is a retrospective cohort study of Mayo Clinic patients with hardware or non-hardware associated chronic orthopedic infections treated with long termminocycline suppre...
Melanin is a pigment that contributes to our skin color. Hyperpigmentation where melanin is produced in excess quantity can cause significant esthetic problem. Facial aesthetics is affected by smile line. Gingiva is an integral component of facial esthetics. Hyperpigmentation in gingiva affects facial esthetics. Various surgical modalities have been employed to correct hyperpigmentation. But, r...
There are numerous common skin disorders involving hyperpigmentation, including solar lentigines, postinflammatory hyperpigmentation, melasma, freckles, and dyschromia from photoaging. While these conditions are of an aesthetic nature, there is great interest in newer, safer, and more effective treatment modalities. Topical hydroquinone (HQ) has been the gold standard of skin lighteners for man...

We previously reported that three point mutations in SASH1 and mutated SASH1 promote melanocyte migration in dyschromatosis universalis hereditaria (DUH) and a novel p53/POMC/Gαs/SASH1 autoregulatory positive feedback loop is regulated by SASH1 mutations to induce pathological hyperpigmentation phenotype. However, the underlying mechanism of molecular regulation to cause this hyperpigmentation ...
