Severe case of pustular psoriasis during pregnancy.

Pustular psoriasis of pregnancy (PPP) is a rare variant of generalised pustular psoriasis occurring during or after pregnancy. PPP can have significant maternal and fetal morbidity if left untreated. In this case report, we present a pregnant woman with this rare cutaneous disorder and how it was treated.

[Atypical presentation of male breast cancer].

Background: Approximately 1% of all breast cancers occur in men. With an annual incidence of 130 cases in the Netherlands, the occurrence of male breast cancer is rare.

Case Description: We report the case of a 72-year-old male who was referred to a breast outpatient clinic for the evaluation of a multinodular skin lesion of the nipple.

Suprainguinal Re-Resection of the Lateral Femoral Cutaneous Nerve in Persistence or Recurrence of Meralgia Paresthetica After Previous Transection: Results of a Case Series.

Objective: Suprainguinal re-resection of the proximal nerve stump can be performed in case of persistent or recurrent symptoms of meralgia paresthetica after previous transection of the lateral femoral cutaneous nerve (LFCN). Currently, no long-term results for this procedure have been reported in the literature.

Methods: In this study, 20 consecutive patients with persistent (13 cases) or recurrent (7 cases) symptoms of meralgia paresthetica were reoperated at a mean interval of 16 months after the first transection of the LFCN.

Optimizing Mutation and Fusion Detection in NSCLC by Sequential DNA and RNA Sequencing.

Introduction: Frequently, patients with locally advanced or metastatic NSCLC are screened for mutations and fusions. In most laboratories, molecular workup includes a multitude of tests: immunohistochemistry (ALK, ROS1, and programmed death-ligand 1 testing), DNA sequencing, in situ hybridization for fusion, and amplification detection. With the fast-emerging new drugs targeting specific fusions and exon-skipping events, this procedure harbors a growing risk of tissue exhaustion.

Deep learning assisted mitotic counting for breast cancer.

As part of routine histological grading, for every invasive breast cancer the mitotic count is assessed by counting mitoses in the (visually selected) region with the highest proliferative activity. Because this procedure is prone to subjectivity, the present study compares visual mitotic counting with deep learning based automated mitotic counting and fully automated hotspot selection. Two cohorts were used in this study.
