Abstract:
The progression of vitiligo and postinflammatory hyperpigmentation simultaneously in a patient with AIDS led to the appearance of a blue color on much of the patient's skin. The blue coloration subsequently resolved with follicular repigmentation typical of resolving vitiligo. We believe this is the first reported case of "blue vitiligo."Keywords:

Hyperpigmentation is a common dermatologic condition that is seen in all skin types but is most prominent in skin of color. In skin of color, any inflammation or injury to skin can almost immediately be accompanied by alterations in pigmentation, either hyperpigmentation or hypopigmentation. Post-inflammatory hyperpigmentation can be observed in many skin conditions including acne, eczema, and contact dermatitis and treatment can be challenging. The goal is to reduce the hyperpigmentation without causing undesirable hypopigmentation or irritation in the surrounding area. This review will discuss current research on treatments for hyperpigmentation and approaches to treating this condition.

Vitiligo is an acquired pigmentary disorder, clinically characterized by depigmented macules caused by destruction of melanocytes in the affected skin. Half of all patients develop the disease in childhood and adolescence before the age of 20 years, making vitiligo an important skin disease of childhood. There are numerous studies in the literature that suggest the efficacy of topical tacrolimus in vitiligo, without serious adverse effects. We describe a case of vitiligo in a pediatric patient who developed hyperpigmentation in the periorbital lesions of vitiligo with the use of topical tacrolimus. To the best of our knowledge, this is only the second such reported occurrence in a patient with vitiligo.

Skin pigmentation disorder is one of the common skin diseases. In general, skin gets its color from melanin pigment, which is produced by melanocytes in the skin. When these cells are damaged, they can negatively affect melanin production. Pigmentation disorders in the skin are classified as hyperpigmentation and hypopigmentation. Hyperpigmentation appears due to increased melanin in the skin. Typical hyperpigmentation disorders include post-inflammatory hyperpigmentation, melasma, solar lentigines, freckles, and café au lait macules. These conditions are generally benign but can be distressing to patients. Addison's disease and some other endocrine disorders may cause diffuse hyperpigmentation. Hypopigmentation is caused by a decrease in melanin production in the skin. Examples of hypopigmentation include vitiligo, albinism, fungal infections, and post-inflammatory hypopigmentation, for example after burns or psoriasis. The nine chapters in this book discuss the latest clinical and therapeutic findings on the most common skin pigmentation disorders and their effect on patients' quality of life.

Demodex-induced facial hyperpigmentation or pigmented demodicosis is the term given to a type of hyperpigmentation on the face with specific clinicopathological and dermoscopic findings that responds to antidemodectic treatment. We report the case of a patient with facial hyperpigmentation caused by Demodex.
