AbstractA 28-year-old man presented with a clinical picture suggestive of complex regional pain syndrome type I following a blow to the thenar eminence and thumb. Symptoms, including swelling of the hand and distal forearm, progressed until an amputation was carried out to rid the patient of an unendurable painful and nonfunctioning wrist and hand. The histologic evaluation of the amputation specimen showed: 1) dermal edema, perivascular dermatitis, and epidermal hyperkeratosis; 2) subcutaneous chronic inflammation with subtotal replacement of the adipose lobules by fibrous tissue associated with thickening of the muscular fascia, implying the fasciitis-panniculitis reaction pattern; 3) atrophy, degeneration, necrosis, and focal calcifications of the skeletal muscles; 4) phlebosclerosis, phlebectasias and lymphocytic arteritis; and 5) increased cortical porosity of the bones. It seems that the pathogenetic process underlying the fasciitis-panniculitis syndrome may rarely manifest as a complex regional pain syndrome-like disorder.
