Reducing workload in malignant melanoma sentinel node examination: a national study of pathology reports from 507 melanoma patients.

Aims: Even though extensive melanoma sentinel node (SN) pathology protocols increase metastasis detection, there is a need for balancing high detection rates with reasonable workload. A newly tested Danish protocol recommended examining nodes at six levels 150 µm apart (six-level model) and using SOX10 and Melan-A immunohistochemistry (IHC). We explored if a protocol examining 3 levels 300 µm apart (three-level model) combined with IHC would compromise metastasis detection.

Elastosis perforans serpiginosa related to vascular Ehlers-Danlos syndrome.

Elastosis perforans serpiginosa (EPS) is a rare skin disease with elimination of connective tissue fibers from dermis to epidermis. The typical presentation shows hyperkeratotic red or skin-colored papules arranged in a circinate pattern. We present a 26-year-old woman with EPS known to have vascular Ehlers-Danlos syndrome.

[Sweet syndrome manifestations].

Sweet syndrome (SS) exists as classical, malignancy-associated, drug-induced and as the new variants: giant cellulitis-like SS and neutrophilic dermatosis of the hands. SS exhibits different morphologies. Skin manifestations are usually accompanied by fever and neutrocytosis.

Henoch-Schönlein Purpura: A Literature Review.

Henoch-Schönlein purpura is the most common childhood vasculitis, but may also affect adults. This article reviews the literature since 2011 on advances in diagnosis, clinical disease manifestations, pathophysiology and treatment of Henoch-Schönlein purpura. The clinical manifestations are thought to arise from IgA depositions in blood vessel walls in the affected organs, mostly skin, gastrointestinal tract, joints and kidneys.

Two cases of erythema induratum of Bazin--a rare cutaneous manifestation of tuberculosis.

Tuberculosis remains a global disease burden, counting more than 9 million new cases per year. Tuberculosis is caused by infection with Mycobacterium tuberculosis-complex. Though most commonly affecting the lungs, any organ can become a site of tuberculous infection.

Can EGFR mutation status be reliably determined in pre-operative needle biopsies from adenocarcinomas of the lung?

The identification of EGFR mutations in non-small-cell lung cancer is important for selecting patients, who may benefit from treatment with EGFR tyrosine kinase inhibitors. The analysis is usually performed on cytological aspirates and/or histological needle biopsies, representing a small fraction of the tumour volume. The aim of the present investigation was to evaluate the diagnostic performance of this molecular test.
