yperpigmentation disorders usually become from increase

of the production of melanin or from increase of the density

of the melanocyte dyschromicum erythema perstans, or ashy

dermatosis, is a rare chronic acquired skin disease characterized

by gray hyperpigmented patches with erythematous borders.

Its etiology is unknown and there is no specific treatment for

the condition. Drug induced hyperpigmentation is caused

by several substances: chemotherapeutic agents, metals,

amiodarone, clofazimine, hydroquinone,minocycline, psoralens

and others. In most of cases, the pigmentation is solved

discontinuing the drug. Post inflammatory hyperpigmentation

appears after a cutaneous injury. UV radiation can make the

lesion worse. In flagellate dermatitis, we can observe linear

macules hyperpigmented on chest and back, mainly and

it appears after using bleomycin; reversible discontinuing

the drug. Vitiligo is an idiopathic disorder characterized by

dyspigmented stains and available melanocytes are not found

in the skin. Many treatments are reported as UVB narrow band,

PUVA, corticosteroids, topical immunosuppressants, surgical

therapies, micropigmentation and lasers. Macular Progressive

Hypomelanosis is very common, mainly in young woman.

It’s characterized by hypopigmented macules on chest and

abdomen, rounded, assintomatica. Prurido is not observed, as

well desquamation. This can be treated with benzoyl peroxide

5% and UVA radiation. Pityriasis versicolor is an infectious

disorder caused by Malassezia sp, a round hypomelanotic

macule appears with desquamation, usually bilateral, on chest

and shoulders or sometimes on abdomen. Hypomelanotic

mycosis fungoides isanearlystageof thedisease.Morecommon

in higher phototypes, 30-40 years old, the lesions occur in torso

and extremities and can be itchy. Hypomelanotic macules can

be found in leprosy and they use to be small, multiples and

not clearly. The lesions are common on face, extremities and

gluteal region. Hyposensitivity and anhidrosis is possible. Halo

nevus is frequent in child and young people. It’s characterized

by a central pigmented nevus and a round amelanotic macule.

Asymptomatic, more common on back.
