Skin color has always been important and interest to people in all cultures. Disorders of skin color, either hyperor hypopigmentation are cosmetically vexing and can be signs of systemic disease. For many centuries physicians have tried to treat such disorders. We review some of the history of treatments for hyperpigmentation and the development of hydroquinone, currently the medication of choi...

Chemical Leukoderma is a rare phenomenon in our local Singapore population. The simultaneous occurrence of both hypopigmentation and hyperpigmentation in our patient, which represents development of Chemical Leukoderma (melanocytic inhibitory reaction) and postinflammatory hyperpigmentation (melanocytic stimulatory reaction) respectively, is presumptively even rarer. Plausible underlying pathop...

Background.  The objectives of this study were to estimate the incidence and evaluate risk factors for development of minocycline-induced cutaneous hyperpigmentation in patients with orthopedic infections. Methods.  Patients with orthopedic infections evaluated at Mayo Clinic (Rochester, MN) and treated with minocycline from 1 January 2002 to 31 December 2011 were retrospectively identified. Lo...

PURPOSE To correlate fundus autofluorescence (FAF) patterns in choroidal melanocytic lesions with changes present on the surface of such lesions, including lipofuscin, hyperpigmentation, drusen, and fibrous metaplasia, and to describe the effect of treatment on FAF. METHODS Retrospective chart review of 23 consecutive patients with choroidal nevi and melanoma who underwent FAF photography. Th...

BACKGROUND Immunosuppressive medications typically used to treat the immunobullous disorders pemphigus vulgaris, pemphigus foliaceous, and bullous pemphigoid can have serious adverse effects. The tetracycline family of antibiotic drugs has been shown to be effective in the treatment of these conditions with a more favorable side effect profile. Minocycline hydrochloride use has been associated ...

Tegafur is a prodrug of 5-fluorouracil (5-FU) with a similar spectrum of antitumor activity. It is used in the treatment of advanced gastrointestinal neoplasms. Over 5-FU, tegafur has the advantage of oral administration and less hematologic toxicity. Gastrointestinal toxicity is its main dose-limiting factor. The cutaneous adverse effects of tegafur include mucositis, photosensitivity, diffuse...

Serpentine supravenous hyperpigmentation is a peculiar cutaneous eruption that follows the path of vein after intravenous injection of the chemotherapeutic agent. The lesions gradually resolve spontaneously if administration of the offending agent is stopped through the affected limb. Drugs such as 5-fluorouracil, docetaxel, vinorelbine, hydroxychloroquine, fotemustine, and minocycline are impl...

A 27-year old male with Hodgkin's lymphoma was treated with combined chemotherapy that included bleomycin. He presented with pruritic erythematous, edematous linear lesions and was diagnosed to have flagellate hyperpigmentation, a rare side effect of bleomycin chemotherapy.

A 62-year-old male with a long history of rosacea, which was well controlled on minocycline, presented to his primary care physician for routine examination. Physical examination was noted for non-palpable, non-pruritic blue patches of hyperpigmentation on the medial aspects of his lower extremities bilaterally. Recognition and management of the findings are discussed.

In literature there are conflicting data on the true incidence of this complication. In some studies the incidence is estimated in 30% of patients treated with sodium tetradecyl s...
