Many of these genetic immunodeficiency diseases may be associated with a variety of cutaneous abnormalities, and recognition of these clinical features may allow an early diagnosis of primary immunodeficiency. Cutaneous abnormalities may include cutaneous infections, atopic- or seborrheic-like dermatitis, macular erythemas, alopecia, poor wound healing, purpura, petechiae, telangiectasias, pigmentary dilution, cutaneous granulomas, extensive warts, angioedema, and lupus-like changes (Table 143-1). Other clinical features often include failure to thrive, visceral infection, autoimmune disorders, connective tissue/rheumatologic diseases, allergic reactions, and neoplasias.
