Guided microscopy

The lichenoid reaction pattern

Dr Blake O'Brien presents a guided microscopy session exploring the histological features of the lichenoid reaction pattern including the changes that occur associated with keratinocyte apoptosis. The demonstration includes examples of neoplastic and inflammatory conditions including benign lichenoid keratosis and lupus.

 

Is it really an SCC? How to spot a Keratoacanthoma  

Dr Angus Collins guides the viewer through how to identify a keratoacanthoma under the microscope and how to distinguish this lesion from a well differentiated squamous cell carcinoma (SCC). Examples include both active and regressed keratoacanthomas as well as SCCs.

 

Normal Skin

Dr Angus Collins describes the microscopic features of normal skin, including its layers and structures.

 

Spongiotic dermatitis

Synonymous terms used by clinicians include dermatitis and eczematous dermatitis to describe spongiotic dermatitis. However, Dr Blake O'Brien, dermatopathologist at SNP, will talk about the histologic features that define dermatitis as spongiotic and discus some of the common causes.

 

Squamous cell carcinoma

Squamous cell carcinomas (SCCs) are the second most frequently diagnosed carcinoma, behind BCCs. Dr Fiona Lehane reviews cases to provide details of various SCC features and explores the use of ancillary stains used to assist in the diagnosis of differentiated, moderately differentiated and poorly differentiated tumours.

 

Leukocytoclastic vasculitis

Two cases of leukocytoclastic vasculitis, also known as hypersensitivity vasculitis are presented by Dr Jill Magee. Inflammatory changes are described and the myriad of causes are considered.

 

Basal cell carcinoma - Non-aggressive types

Dr Jason Gluch, dermatopathologist, gives an introduction into the most common skin tumour, Basal Cell Carcinoma (BCC), in particular the non-aggressive types. 

 

Erythema nodosum

Dr Jill Magee, dermatopathologist, presents a guided microscopy case on Erythema nodosum, a type of panniculitis that presents with red bumps, usually on the lower extremities of young patients (10-30 years old).
