Increased or decreased pigmentation may occur in the skin and its appendages. It may be due to many factors, including inflammation, or may accompany or follow certain skin diseases, such as hchen planus and leprosy. These pigmentary changes may be localized or generalized, and their degree is considerably dependent on racial factors. Drugs may also cause changes in pigmentation, most commonly an increase. It may be difficult to deflne whether the drugs, or the conditions for which they are… 
CUTANEOUS HYPERPIGMENTATION CAUSED BY SYSTEMIC DRUGS
TLDR
This work presents clinical and histologic information about systernic drugs that cause hyperpigmentation and classified the various drugs into the following groups: antimalarials and related drugs, tetracyclines, heavy metals, cancer chemotherapeutic agents, hormones, nitro compounds, carotenoids, phenothiazines and relateddrugs, and miscellaneous.
Drug- and heavy metal--induced hyperpigmentation.
Minocycline-Induced Scleral and Dermal Hyperpigmentation.
TLDR
Long-term minocycline use may induce scleral, dermal, and organ hyperpigmentation, typically blue or black in coloration, and the pigmentation may reverse with discontinuation of the medication, but can also be permanent.
Human skin pigmentation: melanocytes modulate skin color in response to stress

TLDR
This review provides an updated overview of important physiological and biological factors that increase pigmentation and the mechanisms by which they do so and considers endo‐crine factors that induce temporary or permanent changes in skin color.
Oral pigmentation

  • Medicine
    Journal of the European Academy of Dermatology and Venereology : JEADV
  • 2000
TLDR
Evaluation of a patient with oral pigmentation requires a systematic approach with resource to appropriate investigations in certain circumstances, and special attention is given to newly appearing lesions, or those that have changed significantly in appearance.
Chemical Leukoderma.
TLDR
The presence of numerous acquired confetti- or pea-sized macules is clinically characteristic of chemical leukoderma, albeit not diagnostic, and a history of repeated exposure to a known or suspected depigmenting agent at the sites of onset and a macules distribution corresponding to sites of chemical exposure are relevant.
Drug‐induced hair colour changes
TLDR
Of the drugs reported, chloroquine and cancer chemotherapeutic agents have the best evidence to support an association, and other drugs, such as p‐aminobenzoic acid, calcium pantothenate, anthralin, chinoform, mephenesin, minoxidil, propofol, valproic acid and verapamil await confirmatory data.
Two Cases of Pigmented Bowen's Disease
TLDR
The clinical presentation of the previously reported PBD cases were similar to the classic BD except for variable degrees of pigmentation, however, even PBD rarely shows severe pigmentation and should be differentiated from melanoma.

THERAPY OF CHLORPROMAZINE MELANOSIS: A PRELIMINARY REPORT.
TLDR
A method of blocking melanin synthesis by depressing tyrosinase activity was devised and an alternative method of treatment designed to stimulate melatonin production by the pineal gland was employed.
PIGMENT DEPOSITION IN VISCERA ASSOCIATED WITH PROLONGED CHLORPROMAZINE THERAPY.
TLDR
The belief is expressed that the increased melanin production is due, at least partly, to the effect of chlorpromazine on the autonomic nervous system, blocking the production of pigment-lightening factors, of which melatonin is the most important.

TLDR
The present study is based on 350 deeply pigmented patients suffering from fixed eruptions seen during the past 10 years, and provides data that may shed some light on the continuing problem of the localization of the eruptive elements.
