Erythematous papule over a tattoo.

A 38-year-old man presented with an erythematous papule over a longstanding back tattoo. Dermoscopic examination revealed a polymorphous vascular pattern with serpentine and dotted vessels, and shiny white-blueish lines indicating a fibrous stroma mixed with tattoo pigment. Histopathological analysis confirmed fibroepithelioma of Pinkus (FeP).

Malignant pleural mesothelioma: clinical experience and prognostic value of derived neutrophil-to-lymphocyte ratio and PD-L1 expression.

Background: Malignant pleural mesothelioma (MPM) is a rare and aggressive tumor, with a poor prognosis. MPM needs to find prognostic factors of survival. We provided the management of patients with MPM and sought to determine whether pre-treatment levels of derived neutrophil-to-lymphocyte ratio (dNLR) as well as PD-L1 expression were reliable prognostic factors of survival.
