  1. Cutaneous Manifestations of Internal Disease Ronald Buckley, D.O. Dermatology Department Lakeview Medical Center Suffolk,Virginia April 02 2011

  2. Course Objectives: • Cutaneous findings may provide valuable clues to the diagnosis of underlying internal disease. • During this presentation, a limited number of internal diseases manifestations on the skin will be reviewed.

  3. Course Objectives • At the conclusion of this talk, the audience will recognize the cutaneous manifestations of internal diseases involving: integument disorders, blistering diseases, internal cancers, cardiovascular disease, pulmonary disease, rheumatic disease, gastrointestinal, and metabolic disease. • Goals • Help the primary care physician to establish the proper diagnosis and management. • Determine the need for referral to the appropriate specialist.

  27. Erythema Nodousm

  28. Erythema Nodosum

  29. Common Benign Cutaneous Disorders • Erythema nodosum • Differential diagnosis: nodular vasculitis and other panniculitis. • Treatment: elimination of known triggers, bed rest, NSAIDs, colchicine, and supersaturated iodide.

  30. Life Threatening Cutaneous Disorder • Exfoliative Dermatitis (Erythroderma) • Potentially a life-threatening reaction pattern involving the skin. • Location: generalized . • Clinical appearance: generalized and confluent redness and scaling of the skin with associated systemic “toxicity”, generalized lymphadenopathy, pruritus, malaise, chills, and fever. • Causes: most commonly are preexisting skin diseases: • Psoriasis, atopic dermatitis and drug hypersensitivity.

  33. Life Threatening Cutaneous Disorder • Exfoliative Dermatitis (Erythroderma) • Internal Association: Cutaneous T Cell Lymphoma (less commonly), leukemia and pityriasis rubra pilaris. • Differential diagnosis: lichen planus, pemphigus foliaceus, ichthyosiform erythroderma, acute graft-versus-host disease. • Treatment: hospitalized in single room with attention to the patient need for temperature control. Water baths with bath oils followed by application of bland emollients.
