British Society for Dermatopathology 2011 Findings

The document from 2011 presents findings from several dermatological studies and case reports. One study (DP-17) compared the quality of clinical information on pathology requisition forms submitted by dermatologists, GPs, and surgeons, finding that dermatologists provided more complete and differential diagnoses. Another study (DP-18) involving 61 patients with cutaneous vasculitis identified hypersensitivity vasculitis and Henoch-Schönlein purpura as the most common forms, with 60% of cases being idiopathic. A case report (DP-20) detailed a misdiagnosis of pyoderma gangrenosum in a 43-year-old patient, which was later correctly identified as a Staphylococcus aureus skin infection. Additionally, a study (DP-21) on papillary dermal elastolysis with 203 specimens suggested that loss of elastin in the papillary dermis is common in lichenoid conditions. The document also includes a case of granulomatous rosacea diagnosed as FMF stage 1A, treated successfully without systemic treatment, and a unique case of unilateral plaque morphoea coexisting with linear lichen sclerosus, which may be due to X-chromosome lyonization.
