We report 3 patients with granulomatous cutaneous T-cell lymphoma (CTCL) who showed necrobiosis histologically with palisading granulomas. Although granulomatous change may be present in up to 4% of cases of CTCL, necrobiosis is rare. Misdiagnosis may occur if epidermotropism is minimal or if atypical cells are masked by the granulomatous infiltrate. T-cell receptor gene analysis confirmed the presence of clonal T-cell populations in lesional skin from all 3 cases.

Background: Psoriasiform dermatitis can be defined both clinically and histologically, but is not a traditionally recognized clinical or histologic diagnosis.
Objective: Analyze the final clinical diagnosis, demographics and clinical characteristics in patients with histologic psoriasiform dermatitis.
Methods: Retrospective cross-sectional analysis of patients with histologic psoriasiform dermatitis 2004-2017.

Purpose Low-dose total skin electron beam therapy (LD-TSEBT) has recently gained popularity in treating mycosis fungoides (MF) due to its reduced toxicity and favorable response rates. Combining accelerated LD-TSEBT with the modified Stanford technique (mST), a condensed cycling approach, offers a promising and convenient option. However, in vivo dosimetry data confirming the effectiveness of this approach is limited.

Purpose: Brentuximab vedotin (BV) is hypothesized to selectively deplete T regulatory cells (Tregs) that express CD30 and re-sensitize tumors to anti-(PD-1) therapy. This study evaluated responses to BV+pembrolizumab post PD-1 and explored corresponding biomarkers.
Methods: 55 patients with metastatic non-small cell lung cancer (NSCLC) and 58 with metastatic cutaneous melanoma received ≥1 dose of BV+pembrolizumab.

CD4+ T cells contribute to antitumor immunity and are implicated in the efficacy of cancer immunotherapies. In particular, CD4+ T helper 2 (Th2) cells were recently found to block spontaneous breast carcinogenesis. However, the antitumor potential of Th2 cells in targeting established breast cancer remains uncertain.

We report the case of a 69-year-old male with moderate-to-severe ulcerative colitis who developed SDRIFE following the seventh intravenous administration of infliximab. The patient presented with symmetrical, pruritic erythema in the cubital and popliteal fossae, groins, gluteal and retroauricular regions without systemic involvement.
