The diagnostic conundrum of Riehl melanosis and other facial pigmentary disorders: a case report with overlapping clinical, dermoscopic, and histopathological features.

Acta Dermatovenerol Alp Pannonica Adriat 2020 Jun;29(2):81-83

Department of Dermatology and Venereology, Faculty of Medicine, Universitas Indonesia, Dr. Cipto Mangunkusumo Hospital, Jakarta, Indonesia.

Riehl melanosis (RM) is a form of pigmented contact dermatitis that often poses a diagnostic challenge due to overlaps in its clinical, dermoscopic, and histopathological features with other pigmentary disorders. This report highlights significant findings and the proper approach for diagnosis. We present the case of a 47-year-old female with progressive facial hyperpigmentation (irregular, blotchy, grayish patches on the forehead, cheeks, and around the mouth) that acknowledged applying a lightening product before her complaint.

Histopathological Features of Riehl Melanosis.

Am J Dermatopathol 2020 Feb;42(2):117-121

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

Histological features of Riehl melanosis have rarely been compared between lesional and perilesional normal skin and have not been precisely described using quantitative or immunohistochemical analysis or electron microscopic findings. To investigate the histopathological and immunohistochemical features of lesional and perilesional normal skin of patients with Riehl melanosis, we retrospectively evaluated the electronic medical records and skin biopsy specimens of 48 patients with Riehl melanosis. In addition, electron microscopy was performed on 1 case. Read More

Successful Treatment of Riehl's Melanosis With Mid-Fluence Q-Switched Nd:YAG 1064-nm Laser.

Lasers Surg Med 2020 Jan 17. Epub 2020 Jan 17.

Department of Dermatology, Gangnam Severance Hospital, Cutaneous Biology Research Institute, Yonsei University College of Medicine, 211 Eonjuro, Gangnam-gu, Seoul, 06273, Korea.

Background And Objectives: Riehl's melanosis is a chronic acquired hyperpigmentation disorder that causes significant cosmetic problems for patients with this condition. Several treatment options, including low-fluence Q-switched Nd:YAG (QSNY) 1064-nm laser treatment, have been attempted with inconsistent results. We aimed to investigate the beneficial effect of mid-fluence QSNY 1064-nm laser in the treatment of Riehl's melanosis. Read More

Confocal laser scanning microscopy, a diagnostic alternative for five pigmented lesions on the face: An observational study.

Skin Res Technol 2019 Nov 24;25(6):871-876. Epub 2019 Jul 24.

Department of Dermatology, Affiliated Hospital of Xuzhou Medical University, Xuzhou, China.

Objective: To describe the confocal laser scanning microscopy (CLSM) features of five different facial hyperpigmentation diseases and to highlight the features that can be used to differentiate between the diseases.

Acquired diffuse slate-grey facial dyspigmentation due to henna: an unrecognized cause of pigment contact dermatitis in Korean patients.

Eur J Dermatol 2018 Oct;28(5):644-648

Department of Dermatology, Yeouido St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Korea.

Henna is a vegetable hair dye that can be used by individuals who are sensitized to oxidative dyes due to low allergenicity. The reported incidence of slate-grey facial dyspigmentation following the use of henna hair dye is extremely rare. This study aimed to identify the clinical, dermoscopic, and histopathological features of slate-grey facial dyspigmentation following the use of henna hair dye in Korean patients. Read More

Three cases of pigmented cosmetic dermatitis-like eruptions associated with primary Sjögren's syndrome or anti-SSA antibody.

J Dermatol 2016 Aug 19;43(8):947-50. Epub 2016 Feb 19.

Department of Dermatology, Oita University, Kyoto, Japan.

Pigmented cosmetic dermatitis-like (Riehl's melanosis-like) pigmentation was reported in three of 27 patients with primary Sjögren's syndrome. But case reports of such eruptions are rare. We describe three cases of such eruptions associated with primary Sjögren's syndrome or anti-SSA antibody and possible associations with specific types of human leukocyte antigen (HLA) and infiltrating lymphocytes.

Low-pulse energy Q-switched Nd:YAG laser treatment for hair-dye-induced Riehl's melanosis.

J Cosmet Laser Ther 2015 Jun 20;17(3):135-8. Epub 2015 Feb 20.

Department of Dermatology, Cutaneous Biology Research Institute, Gangnam Severance Hospital, Yonsei University College of Medicine , Seoul , Korea.

Riehl's melanosis, a form of dermatitis characterized by reticulate pigmentation, typically presents as a gray-brown to black hyperpigmentation on the face and neck. Among the various etiologic factors suggested, photoallergic reaction and pigmented contact dermatitis resulting from exposure to drugs, coal tar dyes, optical whitener, or other ingredients found in cosmetics are believed to be the major contributing factors in this disease. The histopathological features of Riehl's melanosis mainly consist of pigmentary incontinence along with infiltration of numerous dermal melanophages and lymphohistiocytes. Read More

A pilot study of a novel dual--pulsed 1064 nm Q-switched Nd: YAG laser to treat Riehl's melanosis.

J Cosmet Laser Ther 2014 Dec 13;16(6):290-2. Epub 2014 Aug 13.

Department of Dermatology, Asan Medical Center, University of Ulsan College of Medicine , Seoul , Republic of Korea.

The treatment of Riehl's melanosis is difficult and challenging. Recently, a low-fluence 1064-nm quality (Q)-switched neodymium: yttrium-aluminum-garnet (Nd: YAG) laser method, referred to as 'laser toning', has been used in the treatment of melasma in Asian countries. We present here a series of cases of Riehl's melanosis that were treated effectively with a novel Q-switched Nd: YAG laser that was operated as a dual-pulse at half-fluence and 140-μs intervals.

Riehl melanosis treated successfully with Q-switch Nd:YAG laser.

J Drugs Dermatol 2014 Mar;13(3):356-8

Riehl melanosis is a rare cause of skin hyperpigmentation that typically occurs on the face and neck and is characterized by the rapid onset of gray-brown reticular pigmentation. It is theorized to be a pigmented contact dermatitis or a lichenoid immune reaction that may be caused by intrinsic as well as extrinsic factors. Treatment is challenging; laser and intense pulsed light (IPL) therapy is a common treatment for other pigmented skin conditions. Read More

[Molecular basis of pigmentation disorders in skin diseases].

Przegl Lek 2009 ;66(3):145-9

Pracownia Inzynierii Komórkowej i Tkankowej Zakładu Biologii Komórki, Wydział Biochemii, Biofizyki i Biotechnologii, Uniwersytet Jagielloński, Kraków.

Skin disorders connected with pigmentation disturbances are most frequent dermatological problems. Different mechanisms are involved in these changes, mainly those which regulate melanocyte function. In this work we focused on molecular basis of pigmentation disorders in dermatological diseases that present clinically with hyperpigmentation (lentigo senilis, Riehl melanosis, seborrhoic keratosis, fibroma, café-au-lait patches melasma, atopic dermatitis) or hypopigmentation (vitiligo, albinism).

Riehl's melanosis.

Authors:
H rorsman

Int J Dermatol 1982 Mar;21(2):75-8

In Riehl's melanosis, first observed in 1917, facial hyperpigmentation, most pronounced on the forehead and in the zygomatic and/or temporal regions is the dominant symptom. Riehl could find no explanation for the condition, but suggested that certain foods used during the war could be responsible. Riehl's melanosis has later been observed in dark-complexioned people in whom hyperpigmentation with pigment incontinence may be the main sign of contact dermatitis caused by certain allergens.
