Livedo vasculitis: vasculitis or thrombotic vasculopathy?

Elevated fibrinopeptide A levels, suggestive of a thrombogenic state, were observed in six patients with livedo vasculitis. Serological studies demonstrated normal complement levels, and circulating immune complexes were not identified by standard assays. Morphological studies showed no evidence of immune complex deposition or a neutrophilic vascular reaction. These results support classification of this disorder as a thrombogenic vasculopathy rather than as a small vessel vasculitis. Further investigations into the thrombotic abnormalities underlying this entity are warranted.

Vulvar pyoderma gangrenosum.

Pyoderma gangrenosum is an idiopathic dermatologic disease manifested by painful cutaneous ulceration. The ulcers are characterized by their undermined, violaceous borders and necrotic tissue at the ulcer base. The lesions may have an unusual response to physical manipulation known as pathergy, a phenomenon that is manifested by rapid progression following debridement. Pyoderma gangrenosum is frequently associated with systemic diseases such as inflammatory bowel disease, rheumatoid arthritis, chronic active hepatitis and hematologic malignancies. Conservative wound care and systemic corticosteroids are usually effective therapy. We report the second case in the gynecologic literature of a patient with vulvar pyoderma gangrenosum.

Giant fibromyxoid tumors of the adventitial dermis. Forme fruste of trichodiscoma?

A 36-year-old paraplegic man developed multiple giant fibromyxoid tumors surrounding a meningomyelocele scar that we believe are forme fruste of trichodiscomas. Histologic examination showed a papillated, slightly hyperplastic epidermis surrounding a delicate fibrovascular proliferation set in a stroma of loose fibrillar connective tissue and stellate fibroblasts. A melanocytic nevus was incorporated into one of the lesions. We believe that these giant lesions are connective tissue nevi of the adventitial dermis that comprise a new clinical variant of trichodiscoma. The potential significance of the relationship between these abortive trichodiscomas and abnormalities of the neural crest is discussed.
