A systematic analysis of commonly used antibodies in cancer diagnostics.

Aims: Immunohistochemistry plays a pivotal role in cancer differential diagnostics. To identify the primary tumour from a metastasis specimen remains a significant challenge, despite the availability of an increasing number of antibodies. The aim of the present study was to provide evidence-based data on the diagnostic power of antibodies used frequently for clinical differential diagnostics.

Spectrum of non-infectious erythematous, papular and squamous lesions of the skin.

Background: Dermatopathologists base their diagnostic approach on the tissue reaction pattern. This study mainly includes the interpretation of two major tissue reaction patterns, the psoriasiform and the lichenoid reactions, with clinicopathological correlation.

Aims: To analyze the spectrum of non-infectious erythematous papular and squamous lesions of the skin at our institute, study the age, sex and anatomic distribution pattern and classify the lesions into major categories; determine the incidence of each subcategory.
