If the diagnosis of lichen simplex chronicus is rendered, the clinician can more properly treat and counsel the patient in order to break the itch-scratch cycle that perpetuates the disease. Microscopically, it is similar to granuloma annulare in that it is composed of palisading granulomas, but the granulomas are centered on elastotic collagen fibers without true necrobiosis (Fig. Rheumatoid nodule with well demarcated palisading granuloma.

This is an organization composed of individuals with a professional interest in the microscopic interpretation of skin diseases. Microscopically, granuloma annulare is composed of histiocytes, lymphocytes, and some fibroblasts surrounding a zone of altered collagen with increased mucin deposition between the altered collagen bundles (Fig. Dodiuk-Gad RP, Chung WH, Valeyrie-Allanore L, Shear NH. Cutaneous manifestations are the most common presenting sign.

Acute GVHD is currently defined as having characteristic skin findings, gastrointestinal tract or liver abnormalities, and the absence of features of chronic GVHD irrespective of the timing of the stem cell transplantation. The aims and objectives of the ISDP are to increase knowledge of the structure and function of the skin and of diseases of the skin by microscopy. Not surprisingly, with that level of exposure, many pathologists feel uncomfortable with dermatopathology, especially inflammatory dermatoses. March 6-7, 2024.

Calciphylaxis is associated with mortality in up to 60% of patients, so accurate diagnosis is paramount [72]. In fact, I typically state that establishing the diagnosis of pyoderma gangrenosum is largely based on clinicopathologic correlation. Registration - DIAD-DIAL According to a recently published consensus statement, a biopsy of the wound edge demonstrating a neutrophilic infiltrate is the single major criterion to help establish the diagnosis [71].
