A Case of Lichen Planus Pigmentosus with Facial Dyspigmentation Responsive to Combination Therapy with Chemical Peels and Topical Retinoids.

J Clin Aesthet Dermatol 2016 Nov 1;9(11):44-50. Epub 2016 Nov 1.

Residency Program Director, New York College of Osteopathic Medicine of New York Institute of Technology, Department of Dermatology, St. Barnabas Hospital, Bronx, New York.

Lichen planus pigmentosus is a photodistributed dyschromia of unknown etiology described clinically as hyperpigmented gray-blue or brown-black macules or patches in a photodistributed pattern. Although there has been some debate, lichen planus pigmentosus is considered by many to be a separate diagnostic entity from ashy dermatosis or erythema dyschromicum perstans, which shares similar characteristics. Various treatment strategies have been applied to help resolve or improve the appearance of lichen planus pigmentosus lesions; however, an optimal treatment method is yet to be elucidated. Read More

Bullous lesions in a patient with systemic lupus erythematosus.

J Clin Aesthet Dermatol 2014 Sep;7(9):44-9

Saratoga Dermatology, Saratoga Springs, New York.

Bullous eruptions in patients with lupus erythematosus can be difficult to diagnose as bullous lesions can develop in lupus-specific lesions, and primary blistering disorders can also occur. Additionally, these patients tend to have multiple co-morbidities making them more likely to be on many medications that can lead to bullous drug reactions. A thorough history, the clinical presentation, and histopathological findings along with direct immunofluorescence can be helpful in diagnosing most cases. Read More

Idiopathic eruptive macular pigmentation: report on two cases.

Indian J Dermatol 2010 Jul-Sep;55(3):277-8

Department of Dermatology, Armed Forces Medical College, Pune, Maharashtra, India.

Idiopathic eruptive macular pigmentation (IEMP) is a rather under-reported condition of unknown etiology. Clinically consisting of benign hyperpigmented macules, the condition is characterized histopathologically by dermal melanization. It must be differentiated from lichen planus pigmentosus, erythema dyschromicum perstans, fixed drug eruption and mastocytosis. Read More

Ann Dermatol 2008 Jun 30;20(2):98-101. Epub 2008 Jun 30.

Department of Dermatology, Ajou University School of Medicine, Suwon, Korea.

Idiopathic eruptive macular pigmentation is a rare condition characterized by asymptomatic pigmented macules involving the neck, trunk, and proximal portions of the extremities. On histopathologic examination, there was increased pigmentation of the basal layer in otherwise normal epidermis and scattered melanophages in the papillary dermis. We report a case of a 26-year-old woman with idiopathic eruptive macular pigmentation involving only the flexural areas of the body. Read More

HLA-DR association with the genetic susceptibility to develop ashy dermatosis in Mexican Mestizo patients.

J Am Acad Dermatol 2007 Apr 20;56(4):617-20. Epub 2006 Nov 20.

Department of Dermatology, Hospital General Manuel Gea Gonzalez, Tlalpan, Mexico.

Background: Ashy dermatosis, also known as erythema dyschromicum perstans, is an acquired benign disease, characterized by blue-gray pigment patches with erythematous borders. The cause is still unclear, but probably has an immunologic basis.

Objective: The aim of this study was to determine gene frequencies of the HLA-DR alleles in Mexican patients with ashy dermatosis and compare them with ethnically matched healthy control subjects to reveal the genetic susceptibility to develop ashy dermatosis. Read More
