A 62-year-old man was seen with an ulcer of the left upper eyelid of two weeks' duration. Over the previous 40 years, similar ulcers had intermittently developed elsewhere on his skin and spontaneously resolved over several months leaving atrophic scars. A biopsy specimen of the eyelid lesion showed epidermal ulceration with acute inflammation and liquefactive necrosis of the underlying dermis. Microorganisms and vasculitis were not present. On the basis of the clinical history and a compatible biopsy specimen, the diagnosis of pyoderma gangrenosum was made. This is an uncommon, idiopathic, ulcerating skin disease that may also have ocular manifestations. Eyelid ulcers have not previously been reported, to our knowledge. The diagnosis is established by clinical history and exclusion of other causes of ulceration.

Crohn's disease is a chronic inflammatory bowel disease which may have distinctive mucocutaneous manifestations. Included in this group are perianal, peristomal, and perifistular ulceration, as well as granulomatous cutaneous inflammation separate from gastrointestinal tract openings (metastatic Crohn's disease). In the oral cavity, both ulcerations and granulomatous nodules may occur. Malabsorption of nutrients may lead to several changes, including an acrodermatitis enteropathica-like syndrome secondary to zinc deficiency. Patients with Crohn's disease may also have pyoderma gangrenosum, erythema nodosum, cutaneous vasculitis, and other less specific changes.

Pyoderma gangrenosum is a destructive cutaneous disorder characterized by painful, rapidly enlarging ulcers with under-mined bluish and purplish red margins. This disease is most frequently found in association with ulcerative colitis. However, in the last three years, four cases of pyoderma gangrenosum precipitated by surgical procedures have occurred, and only one of these patients had ulcerative colitis. All four patients responded to steroid therapy and local wound care. Pyoderma gangrenosum can first be suspected by recognition of the previously described classic lesion. In addition, the absence of significant microbial growth and the lack of a specific etiology ascertained on routine and special staining of biopsy material is suggestive of the diagnosis. Histologic characteristics are entirely nonspecific but can be helpful in ruling out other specific entities. The progressively destructive nature of this process in the face of what would seem to be appropriate therapy for bacterial wound infection requires that pyoderma gangrenosum, as well as other aspects of the differential diagnosis of a persistent ulcerative lesion, such as fungal infection, factitious ulcer, or vasculitis, be considered.

A case of Crohn's colitis is described in a patient who demonstrated multiple extraintestinal complications, including erythema nodosum, pyoderma gangrenosum, and aphthous oral ulcerations. Our patient simultaneously developed an unusual vasculitis in muscle. Small vessels were affected by necrosis, and polymorphonuclear leukocyte infiltration was appreciated. Leukocytoclastic was suggested by these features and the additional finding of small amounts of nuclear debris. A strong immunofluorescence to antihuman C3 was demonstrated in the affected vessel walls. We did not find circulating IgG immune complexes in serum with the Raji cell assay. The implication of the finding of leukocytoclastic vasculitis in muscle, associated with Crohn's colitis, is discussed.

Spontaneous avulsion of both quadriceps tendons occurred in a young woman who had been treated with corticosteroids for progressive severely deforming seronegative arthritis and recurring skin lesions clinically and histologically suggestive of cutaneous vasculitis and pyoderma gangrenosum. We postulate that recurrent minor trauma to tendons previously damaged by vasculitis and inhibition of tendon repair by oral corticosteroids were predisposing factors to the bilateral tendon avulsions.

After a short exposition of the meaning and the technique for determination of immune complexes in circulating blood (after Hashkova, with polyethylene glycol) our first experience with phlebological patients is exposed. Positive reactions in a variety of cases (N = 122) includes atypical ulcus cruris, ulcerated vasculitis, Pyoderma gangrenosum, discoid lupus erythematodes, chronic rheumatoid polyarthritis (with, or without ulcus cruris), monoarthritis of the knee, pernicious anemia, chronic lymphedema (elephantiasis), some cases of sclerosis multiplex. In such positive cases the sedimentation rate of citrate blood may, or may not be elevated. Negative or uncertain reactions (below 10) were seen in 141 cases, in common's ulcus cruris cases, in vasculite nodulaire, in discopathy and most spondylarthroses and other arthrosis cases, in vasculite nodulaire, in discopathy and most spondylarthroses and other arthrosis cases, in various patients with rheumatoid complaints in coxarthrosis, osteoporosis and in a group of healthy young persons. Negative reactions were the rule in atherosclerotic and diabetic old persons with claudication or gangrene, in most dermatological cases, in necrobiosis lipoidica, in psoriasis, in postthrombotic phlebitis and in chronic rheumatism in a quiet stage. In vasculitis cases the reaction is often only slightly positive (between 10 and 20) but should be repeated as the values may vary. The determination of circulating immune complexes with polyethylenglycol is a useful screening method in the policlinic. Treatment is often directed in the right way sometimes prednisone, more often nivaquin (chloroquin) or other anti-inflammatory drugs and in pernicious anemia hepatotherapy can be of great help in the healing of complicated phlebological cases.

Globular deposits of immunoglobulins in the papillary dermis have been reported to occur in certain dermatoses, particularly in lichen planus. The clinical correlation of these deposits in 52 skin biopsy specimens reviewed by light and fluorescent microscopy was studied. These cases included five of lichen planus, 24 of lupus erythematosus or related diseases, four of dermatitis herpetiformis, three of drug eruption; two each of bullous pemphigoid, erythema nodosum, porphyria cutanea tarda; one each of vitiligo, pyoderma gangrenosum, neurodermatitis, erythema multiforme, granuloma annulare, vasculitis, epidermolysis bullosa simplex, Rothmund-Thompson syndrome, and four of unspecified dermatoses. Using an arbitrary scale of 1-4 based on the frequency of deposits, 3+ and 4+ deposits were identified in all five cases of lichen planus, as well as in six cases of lupus erythematosus, one of drug eruption, one of bullous pemphigoid, one of erythema nodosum, the vitiligo, vasculitis, and Rothmund-Thompson syndrome cases, and two cases of unspecified dermatoses; other cases showed only 1+ and 2+ deposits. In all five cases of lichen planus, the deposits contained IgM and C3, and in addition, IgA was present in four, IgG and fibrinogen in three. Among non-lichen planus cases, C3 was detected in 11 of 49, and fibrinogen in only four of 49. These findings indicate that globular deposits of Ig in the dermis, though suggestive, are not pathognomonic of lichen planus.

Leg ulcers are a significant medical problem in the United States. The number of affected patients at any given time is staggering. Treatment modalities have widely varied and are often unsuccessful. We evaluated the effectiveness of cultured epithelial autografts in the treatment of leg ulcers due to various etiologies that had failed other standard therapy. Eighty-six ulcers in 36 patients were treated with cultured epithelial autografts after full evaluation of their ulcers. The ulcers were grouped by etiology and healing was assessed by time to healing, number of ulcers healed and mean number of graft applications. The results achieved in the past five years have shown that cultured epithelial autografts are highly effective in treating chronic leg ulcers. Eighty percent of venous insufficiency ulcers healed in 5.7 weeks. Similar results were seen with ulcers of other etiologies including arterial insufficiency, pyoderma gangrenosum, scleroderma, and vasculitis. Positive results were seen in cases where other treatment methods had failed and seems independent of systemic corticosteroids.

Pyoderma gangrenosum is a rare condition which is sometimes associated with ulcerative colitis and Crohn's disease. The pathological basis is not completely understood but it may be caused by vasculitis. The lesions are typically said to have purple overhanging edges and a necrotic base. The condition may also occur with rheumatoid arthritis, multiple myeloma and leukaemia. The treatment of choice is systemic steroids but it may also respond to azathioprine, minocycline or clofazimine.

Treatment of any wound begins with the correct diagnosis. The vast majority of chronic wounds can be classified as pressure ulcers, venous ulcers, insensate ulcers, or arterial insufficiency ulcers. This article focuses on wounds of unusual origin that must be considered in evaluation. All of these wounds are difficult to treat, are more likely to occur in specialized clinical settings, may provide clues to underlying systemic illnesses, and can be life-threatening. Unusual wounds discussed include atrophe blanche, calciphylaxis, leukocytoclastic vasculitis, necrobosis lipoidica, necrotizing fasciitis, and pyoderma gangrenosum.
