Erythroderma: A clinicopathological study of 47 cases from 2018 to 2020.

Dermatol Ther 2020 11 10;33(6):e14342. Epub 2020 Oct 10.

Department of Dermatology and Venereology, Cerrahpaşa Medical Faculty, Istanbul University-Cerrahpasa, Istanbul, Turkey.

Erythroderma, or exfoliative dermatitis, is an inflammatory disorder characterized by erythema and scaling, affecting most of the skin surface. It may be a result of many different causes such as previous dermatoses (psoriasis, eczema, atopic dermatitis [AD], pityriasis rubra pilaris, and pemphigus foliaceous), drug reactions, malignancies (mycosis fungoides [MF], Sézary syndrome, adult T cell leukemia/lymphoma), infections, and idiopathic disorders. Regardless of the etiology, the clinical appearance of erythroderma is similar in all patients. Read More

Phototherapy in the Evaluation and Management of Photodermatoses.

Dermatol Clin 2020 Jan 18;38(1):71-77. Epub 2019 Oct 18.

Department of Dermatology, Henry Ford Health System, 3031 West Grand Boulevard, Suite 800, Detroit, MI 48202, USA. Electronic address:

Ultraviolet light (UV) and visible light are important components in the diagnosis of photodermatoses, and UV has the unique ability to also be used to manage photodermatoses. Phototesting, provocative light testing, and photopatch testing can provide important information in diagnosing patients with photodermatoses; phototesting can be used to determine the starting dose for phototherapy in these patients. Once photosensitivity is established, narrowband UVB and UVA1 therapy have helped to improve the quality of life of photosensitive patients, such as those with polymorphous light eruption, chronic actinic dermatitis, and solar urticaria.

Do We Utilize Our Knowledge of the Skin Protective Effects of Carotenoids Enough?

Antioxidants (Basel) 2019 Jul 31;8(8). Epub 2019 Jul 31.

School of Medicine, University of Zagreb, Šalata 3, 10 000 Zagreb, Croatia.

Due to their potential health-promoting effects, carotenoids have drawn both scientific and public attention in recent years. The primary source of carotenoids in the human skin is diet, mainly fruits, vegetables, and marine product, but they may originate from supplementation and topical application, too. In the skin, they accumulate mostly in the epidermis and act as a protective barrier to various environmental influences. Read More

Photodermatoses in the Pigmented Skin.

Adv Exp Med Biol 2017 ;996:111-122

Department of Dermatology and Venereology, All India Institute of Medical Sciences, Ansari Nagar, New Delhi, 110029, India.

Skin colour (specifically in relation to its melanin content and composition) has a marked influence on its interaction with ultraviolet light. Eumelanin has mainly photoprotective properties while pheomelanin has the ability to cause formation of reactive oxygen species. This difference is responsible for the difference in incidence and presentation of various idiopathic photodermatoses in dark skinned patients compared to those with lighter skin types. Read More

Narrowband UVB-induced iatrogenic polymorphous light eruption: a case and suggestions to overcome this rare complication.

Dermatol Online J 2016 Jun 15;22(6). Epub 2016 Jun 15.

UCSF Psoriasis and Skin Treatment Center.

Polymorphous light eruption (PMLE) is the most common photodermatosis characterized by pruritic papules and papulovesicles, which appear hours to days following ultraviolet (UV) exposure. Herein, the authors report successful treatment of generalized plaque psoriasis with Goeckerman regimen in a patient despite new onset iatrogenic PMLE following narrowband (NB) UVB therapy. Although further studies are necessary, this case suggests that the co-existence of psoriasis and PMLE should not prevent the use of phototherapy; phototherapy, especially as part of the Goeckerman regimen, remains a valuable treatment option for psoriasis in patients with PMLE.

Unilateral unique Lupus tumidus: pathogenetic mystery and diagnostic problem.

Wien Med Wochenschr 2016 May 13;166(7-8):250-3. Epub 2016 Jan 13.

Policlinic for Dermatology and Venereology, University Hospital Lozenetz, Koziak street 1, 1407, Sofia, Bulgaria.

Lupus tumidus is a rare immunological disorder whose pathogenesis is not fully understood. Although on the one hand there are some differences in (1) the clinical morphology of lesions, (2) the histopathology picture, as well as in (3) serological profile of lupus tumidus patients at the current moment, the disease is regarded as a subform of chronic cutaneous lupus erythematosus. Differential diagnosis requires the exclusion of many diseases such as Jessner Kanoff lymphocytic infiltration, polymorphous light eruption, and reticular erythematous mucinosis. Read More
