Clinical and Pathological Spectrum of Prurigo Pigmentosa in Central European Individuals.

Importance: Based on early studies, prurigo pigmentosa (PP) was considered a rare inflammatory dermatosis affecting primarily Asian individuals. However, several case reports subsequently showed that the disease is not restricted to those of Asian origin. Large studies on PP in central European individuals, on the other hand, are missing.

Essential thrombocythemia manifesting as livedoid and purpuric skin lesions: Report of two cases and literature review.

Essential thrombocythemia is a chronic myeloproliferative syndrome which usually runs its course as an asymptomatic elevated platelet count. Cutaneous manifestations secondary to microcirculation abnormalities are rare but can represent a helpful diagnostic clue in order to prevent major thromboembolic events. We report two cases of heterogeneous livedoid and "net-like" skin lesions in the context of essential thrombocythemia with identical histopathologic findings (medium-sized blood vessels with luminal obliteration by eosinophilic material, mostly positive for the platelet marker CD61, without vasculitis).

Blocking STAT3/5 through direct or upstream kinase targeting in leukemic cutaneous T-cell lymphoma.

Leukemic cutaneous T-cell lymphomas (L-CTCL) are lymphoproliferative disorders of skin-homing mature T-cells causing severe symptoms and high mortality through chronic inflammation, tissue destruction, and serious infections. Despite numerous genomic sequencing efforts, recurrent driver mutations have not been identified, but chromosomal losses and gains are frequent and dominant. We integrated genomic landscape analyses with innovative pharmacologic interference studies to identify key vulnerable nodes in L-CTCL.

[Orchiectomy due to early syphilis].

Granulomatous and abscessing testicular inflammations are important differential diagnoses of testicular tumors. Infectious orchitis should always be considered in unclear testicular masses with negative tumor markers. We report the case of a 45-year-old man with abscessing orchitis due to early syphilis diagnosed after orchiectomy with the suspicion of a seminoma.

Quality of Life, Anxiety, and Depression in Patients With Early-Stage Mycosis Fungoides and the Effect of Oral Psoralen Plus UV-A (PUVA) Photochemotherapy on it.

Little is known about psychological discomfort and quality of life (QoL) in early stage mycosis fungoides (MF) and the effect of psoralen plus UV-A (PUVA) on it. To evaluate QoL, anxiety, and depression with validated instruments in early stage MF patients and whether PUVA treatment improves it. Patients with stage IA to IIA MF were treated with PUVA twice weekly for 12-24 weeks, followed by maintenance treatment or not, in a prospective randomized clinical trial.

The importance of total-body photography and sequential digital dermatoscopy for monitoring patients at increased melanoma risk.

Background And Objectives: The incidence of melanoma is rising and prevention plays an important role. Multiple nevi as well as a medical history of melanoma are important risk factors. In affected patients, a two-step algorithm consisting of total-body photography (TBP) and sequential digital dermatoscopy (SDD) is a helpful diagnostic tool.

Papular Mycosis Fungoides Is a Distinctive Variant of Early-stage Mycosis Fungoides: Extended Retrospective Study With Long-term Follow-up.

Papular mycosis fungoides (PMF) is a rare variant of mycosis fungoides (MF). The exact nosology and prognosis of PMF are still unclear. We retrospectively identified cases of PMF from the files of the Department of Dermatology of the Medical University of Graz, Austria, and checked the follow-up data.

Evaluation of Low-Dose, Low-Frequency Oral Psoralen-UV-A Treatment With or Without Maintenance on Early-Stage Mycosis Fungoides: A Randomized Clinical Trial.

Importance: Psoralen-UV-A (PUVA) photochemotherapy is standard first-line treatment for skin-limited, early-stage mycosis fungoides capable of producing high initial complete response (CR) rates. However, much remains unknown about PUVA's therapeutic mechanisms, optimal duration and frequency of treatment, dose escalation, or use as maintenance therapy.

Objectives: To evaluate low-dose, low-frequency PUVA, and whether maintenance treatment extends disease-free remission in patients with mycosis fungoides.
