Dramatic response to brentuximab vedotin in a refractory non-transformed CD30-negative mycosis fungoides allowing allogeneic stem cells transplantation and long-term complete remission.

Br J Dermatol 2018 Sep 30. Epub 2018 Sep 30.

Dermatology Department, AP-HP Hôpital Saint-Louis, Paris.

The erythrodermic ulcerated form of mycosis fungoides (MF) is exceptional, and treatment of refractory cases is therefore very challenging. Brentuximab Vedotin (BV) is a monoclonal antibody combined with monomethyl auristatin E, recently approved for the treatment of refractory cutaneous T-cell lymphoma with CD30 expression. We report in this article a case of refractory MF in a 56 year-old man with a long story of large plaque parapsoriasis, as revealed by a psoriasiform erythroderma, treated initially with CHOP (cyclophosphamide, doxorubicine, vincristine and prednisone) polychemotherapy inducing a two year complete response.

Photodermatol Photoimmunol Photomed 2018 Sep 29. Epub 2018 Sep 29.

Research Unit for Photodermatology, Department of Dermatology, Medical University of Graz, Graz, Austria.

Background: Medical phototherapy can lead to the manifestation of polymorphic light eruption (PLE), though little is known about the frequency of such events.

Aims: The aim of this Austrian single center study was to retrospectively investigate over a 4-year time period the frequency of PLE in patients prone to the condition and patients with other diseases under phototherapy (mainly narrow-band and broad-band UVB).

Materials And Methods: The data for analysis were obtained from the electronic health and patient record database and patient files of the Photodermatology Unit, Department of Dermatology, Medical University of Graz, Austria. Read More

Varicella zoster virus as a possible trigger for the development of pityriasis lichenoides et varioliformis acuta: retrospective analysis of our institutional cases.

Clin Exp Dermatol 2018 Aug 23;43(6):703-707. Epub 2018 May 23.

Department of Dermatology, Kyorin University School of Medicine, Tokyo, Japan.

Although numerous infective agents, including varicella zoster virus (VZV), have been described in association with pityriasis lichenoides et varioliformis acuta (PLEVA) and pityriasis lichenoides chronica (PLC), none has been identified consistently in these lesions. We sought to immunohistochemically identify VZV glycoprotein (g)E antigens in the vascular endothelium in PLEVA and PLC lesions, based on our previous observation that gE was detected in the vascular endothelium and eccrine unit up until 2 months and 2.5, respectively, years after herpes zoster (HZ) infection.

Department of Dermatology, Huashan Hospital, Fudan University, 12 Middle Wulumuqi Rd., Jing'an District, Shanghai, China.

Psoriasis and parapsoriasis en plaques are chronic inflammatory skin diseases, both representing therapeutic challenge in daily practice and adversely affecting the quality of life. Reactive oxygen species (ROS) has been evidenced to be involved in the pathogenesis of the chronic inflammatory diseases. We now report that hydrogen water, an effective ROS scavenger, has significant and rapid improvement in disease severity and quality of life for patients with psoriasis and parapsoriasis en plaques.

Possible role of plasmacytoid dendritic cells in pityriasis lichenoides.

Clin Exp Dermatol 2018 Jun 19;43(4):404-409. Epub 2018 Jan 19.

Department of Dermatology, American University of Beirut Medical Center, Beirut, Lebanon.

Background: Plasmacytoid dendritic cells (pDCs) and their product, type I interferons (IFNs), have been implicated in the pathogenesis of several skin disorders characterized by an interface dermatitis (ID) pattern, such as lichen planus (LP). A type I IFN signature has previously been documented in pityriasis lichenoides (PL). Although pDCs are known to be the main source and most potent producers of local type I IFNs, their role in PL has not been investigated. Read More

Severe Mucha-Habermann-Like Ulceronecrotic Skin Disease in T-Cell Acute Lymphoblastic Leukemia Responsive to Basiliximab and Stem Cell Transplant.

Pediatr Dermatol 2017 Sep;34(5):e265-e270

Division of Oncology, Children's Hospital of Philadelphia, Philadelphia, Pennsylvania.

A 5-year-old girl with T-cell acute lymphoblastic leukemia (T-ALL) developed a progressive eruption of crusted papules and ulcerative plaques involving 80% of her body surface area with histopathology consistent with febrile ulceronecrotic Mucha-Habermann disease (FUMHD), although multiple specimens also contained clonal leukemic cells. Her skin disease was refractory to many classic treatments for FUMHD, including methotrexate, and became so severe that concern about superinfection prevented intensification of chemotherapy for her malignancy. The addition of basiliximab promoted gradual improvement of the skin, allowing for chemotherapy intensification and subsequent bone marrow transplantation, after which the eruption resolved completely.

Primary cutaneous lymphomas represent a broad group of diseases with different clinical, histopathological, phenotypic, molecular, and prognostic features. All cutaneous lymphomas share the same tropism of neoplastic lymphocytes for the skin, but precise classification is paramount for proper management of the patients. Primary cutaneous lymphomas are classified according to the schemes proposed by the European Organization for Research and Treatment of Cancer (EORTC)-Cutaneous Lymphomas Task Force together with the World Health Organization (WHO) in 2005, and the WHO classification of 2008 with the 2016 update.

Phototherapy can be a safe and effective treatment for various skin diseases in children. Special considerations governing the use of this treatment modality in pediatric populations include patient, family, and facility-based factors that are oriented around heightened concerns with regard to safety and tolerability of treatment. Although phototherapy has been found to be effective in a wide range of dermatologic conditions affecting pediatric populations, including psoriasis, atopic dermatitis, pityriasis lichenoides, cutaneous T-cell lymphoma, and vitiligo, there is need for additional research on other conditions in which phototherapy has shown promise.

Granulomatous slack skin - seven years follow-up of a case with features of "parapsoriasis en plaques", muscle involvement, granulomatous vasculitis, and necrobiotic changes.

Rom J Morphol Embryol 2016 ;57(2):539-46

Department of Dermatology, "Carol Davila" Central University Emergency Military Hospital, Bucharest, Romania;

Granulomatous slack skin (GSS) represents an extremely rare variant of mycosis fungoides with only 70 cases reported in the literature to date. It is characterized clinically by the occurrence of bulky, pendulous skinfolds, usually located in flexural areas and histologically by an infiltrate composed of small neoplastic T-lymphocytes joined by granulomatous inflammation with scattered multinucleated giant cells containing nuclei arranged in a wreath-like fashion. Since its first description, very rare cases of GSS with muscle involvement, large vessels involvement, or necrobiotic changes have been reported. Read More

Introduction: Paraviral exanthems are skin diseases suspected to be caused by viruses, with a single virus-exanthem relationship not universally accepted. Although most paraviral exanthems are self-remitting, accurate diagnoses are important as some patients might develop complications. Some of the differential diagnoses might cause serious complications, and some paraviral exanthems might lead to complications for at-risk groups such as pregnant women. Read More

Tailor systemic therapy to the patient with severe psoriasis.

Practitioner 2016 Feb;260(1790):23-6, 3

There is no standard definition regarding the severity of psoriasis, and a number of factors should be considered, including the extent and stability of skin disease, involvement of joints, response to treatment, and impact on quality of life. Erythrodermic psoriasis and pustular psoriasis are severe conditions and the patient may be systemically unwell and febrile. NICE recommends that four key areas should be evaluated and recorded when assessing patients: severity, using the static Physician's Global Assessment (sPGA); disease impact on physical, psychological and social wellbeing using the Dermatology Life Quality Index (DLQI); the presence of psoriatic arthritis; and comorbidities.

Lymphomatoid contact dermatitis (LCD) is a rare variant of noneczematous allergic contact dermatitis, which can mimick parapsoriasis or early-stage mycosis fungoides with its atypical clinical and histopathological manifestation. Many different haptens have been reported to be associated with this reaction.
