Development of folliculitis and pyoderma gangrenosum in association with abdominal pain in a patient following treatment with isotretinoin.

A 19-year-old man with severe acne developed extensive scalp folliculitis and later superficial pyoderma gangrenosum following treatment with isotretinoin. A cyclical neutropenia was noted and bone marrow findings suggested myelodysplasia. We believe that isotretinoin was implicated in the development of overt symptoms in this patient whose haematological condition was previously asymptomatic.

Pyoderma gangrenosum complicating Crohn's disease.

Of the many acknowledged systemic complications of inflammatory bowel disease, arthritis, iritis and erythema nodosum are observed most commonly and considered parts of the natural history. Pyoderma gangrenosum is a more ominous, less common but similarly associated complication that classically occurs in the course of ulcerative colitis. Its rarity in Crohn's disease stimulated the following report.

Recalcitrant pyoderma gangrenosum--two cases successfully treated with cyclosporin A.

The successful use of cyclosporin A (CSA) in organ transplantation is now well established. In recent years its usefulness has extended to the treatment of cutaneous autoimmune disorders, including pyoderma gangrenosum (P.G.). We report two further cases of recalcitrant P.G., both associated with rheumatoid arthritis (R.A.) which responded to low dose CSA.

Sulfapyridine and sulfones decrease glycosaminoglycans viscosity in dermatitis herpetiformis, ulcerative colitis, and pyoderma gangrenosum.

Shortly after the introduction of sulfa drugs, sulfapyridine was found to have unique therapeutic properties, unrelated to antibacterial activity. Later, sulfones were found to share the same properties. The disorders initially improved were dermatitis herpetiformis, pyoderma gangrenosum, subcorneal pustular dermatosis, acrodermatitis continua, impetigo herpetiformis and ulcerative colitis. They were also sometimes helpful in many other disorders. They are effective in select disorders characterized by edema followed by granulocytic inflammation or edema followed by vesicle or bullae formation. The sulfones work in low doses in leprosy and their mode of action is not fully understood. Several pieces of experimental information are available. It is proposed that these drugs are entering or influencing the protein moiety of glycosaminoglycans and decreasing tissue viscosity. This decreased tissue viscosity prevents edema and dilution of tissue fluid and decreases acute inflammation and vesicle and bullae formation.

Pyoderma gangrenosum and hairy cell leukemia.

Hairy cell leukemia (HCL) is an uncommon hematologic malignancy in which simultaneous cutaneous disturbances of various types have been reported. We report a case of a 62-year-old man with HCL who developed pyoderma gangrenosum (PG) at the site of incision for splenectomy. PG has been reported previously in a patient with HCL. Since splenectomy is important in the treatment of HCL, it is important for the clinician to know that surgical wound dehiscence may not be due to poor technique nor infection, but rather to pathergy.

Cutaneous vasculitis, hypersensitivity vasculitis, erythema nodosum, and pyoderma gangrenosum.

Cutaneous vasculitis encompasses a highly heterogeneous group of disorders of diverse etiology, pathogenesis, and clinical features. Recent reexamination of clinical pathologic features have yielded no insights assisting our understanding of current clinical classification schemes and strengthening our clinical approach. Erythema nodosum is a common cutaneous disorder for which new etiologies continue to be described. Pyoderma gangrenosum is an uncommon ulcerative cutaneous condition that remains a therapeutic problem.

Squamous syringometaplasia in lobular panniculitis and pyoderma gangrenosum.

Squamous metaplasia of eccrine sweat glands has been most frequently described in chronic cutaneous ulcerations with associated epidermal hyperplasia. We found examples of the process in skin biopsy specimens from five patients: three had associated lobular panniculitis and two had lesions of pyoderma gangrenosum. The metaplasia was located in the mid-to-deep reticular dermis in all five patients and extended into the superficial subcutis in one. Immunohistochemical stains for CEA and S-100 protein were used to accentuate the relationship of the metaplastic islands with eccrine ducts. It is postulated that necrosis of a portion of the eccrine duct is the stimulus for this process.

[Post-traumatic pyoderma gangrenosum: combination therapy with intravenous immunoglobulins and systemic corticosteroids].

Pyoderma gangraenosum is a rare, chronic type of skin ulceration of unknown aetiology. It occasionally appears following trauma. There are no set standards for the treatment of pyoderma gangraenosum. It is essential to consider acuteness of progression as well as underlying systemic diseases and possible drug side effects before initiating a therapy. Immunosuppressive as well as immunomodulating agents are most often used with varying degrees of success. We report a 45-year-old patient who suffered from an extensive posttraumatic pyoderma gangraenosum after cardiac bypass operation. With short-term combination therapy consisting of high dose intravenous immunoglobulins and systemic corticosteroids, the progression of the disease could be stopped within a few days.

Pyoderma gangrenosum associated with regional enteritis. Improvement in defective granulocyte function and healing of skin lesions during administration of clofazimine.

A defective uptake of oxygen by peripheral blood granulocytes during phagocytosis, indicating a subnormal phagocytic capacity, has been found in a patient with regional enteritis complicated by pyoderma gangrenosum (PG). During administration of clofazimine and granulocyte function normalized and the skin lesions healed. It is possible that a defective granulocyte function may sometimes be involved in the pathogenesis of PG and that a clofazimine-induced improvement in the function will favour healing of the lesions. The result of treatment in our patient and in other cases recently published indicates that the drug may be worth trying in PG.

Clinical course and evolution of erythema nodosum and pyoderma gangrenosum in chronic ulcerative colitis: a study of 42 patients.

The authors examined 1132 patients with chronic ulcerative colitis (CUC) seen at the Cleveland Clinic to clarify the relationship between the clinical features of colitis and the incidence and severity of erythema nodosum (EN) and pyoderma gangrenosum (PG). There were 21 patients (2%) with EN and 21 (2%) with PG, both of which affected those with active and extensive colitis. CUC was inactive in only 10% of the EN group and 20% of the PG group; it was left-sided in 20% of the EN group and 15% of the PG group. The mean duration of CUC before the appearance of EN and PG was 5 and 10 years, respectively. Three patients had consulted a dermatologist for PG before a clinical diagnosis of CUC was made. EN and PG recurred in 20 and 33% of cases, respectively. EN appeared almost exclusively on the legs, while PG appeared on various areas of the skin, including the site of ileostomy in one patient. EN was controlled with adequate medical or surgical treatment of CUC, but PG was relatively refractory, requiring specific treatment of its own in 30% of patients. In one case each, EN and PG recurred after subtotal colectomy but had resolved completely after proctectomy. In one patient, PG developed for the first time 1 year after total colectomy. Less than half of EN patients and two-thirds of PG patients ultimately had to undergo colectomy because of bowel disease. No patient required colectomy because of skin lesions.

Pyoderma gangrenosum in association with erythema elevatum diutinum: report of two cases.

We report on the appearance of centrifugally spreading ulcers with undermined borders in two patients with chronic recurrent erythema elevatum diutinum controlled with dapsone. The ulcerated lesions were consistent on clinical and pathologic examination with the diagnosis of pyoderma gangrenosum. They eventually responded to treatment with oral corticosteroids. The addition of cyclosporine was required in one case. No associated disease was found in any of the patients. The possible pathophysiological mechanisms of this uncommon association are reviewed.

Post-surgical pyoderma gangrenosum of the vaginal vault associated with ulcerative colitis and Behçet's disease; a case report.

A case is described in which a patient with ulcerative colitis developed chronic vaginal ulceration around the incision lines after cone biopsy. The ulcers persisted at the vaginal vault after abdominal hysterectomy and removal of a cuff of vagina. Non-specific histological features compatible with pyoderma gangrenosum were found on biopsy. The auto-immune nature of this chronic ulcer is further supported by its rapid response to steroid therapy and the subsequent development of Behçet's syndrome.

Pseudoepitheliomatous hyperplasia and pyoderma gangrenosum after a brown recluse spider bite.

Brown recluse spider bites may result in extensive soft tissue injury, causing months of disability. We have described a patient who had a series of extensive surgical debridements after envenomation. Despite skin grafting, persistent cutaneous lesions and extensive satellitosis progressed to involve the entire lower extremity. A recent biopsy showed pseudoepitheliomatous hyperplasia and pyoderma gangrenosum complicating the original injury. Although the role of early surgical excision and newer forms of medical treatment including dapsone and antivenom are still in evolution, recent reports suggest that the majority of patients will respond to medical therapy and may not require any surgical intervention.

Bullous pyoderma gangrenosum after granulocyte colony-stimulating factor treatment.

The hematopoietic growth factors are under investigation for the treatment of patients with chemotherapy-induced bone marrow suppression. One such trial at the University of California, Los Angeles involves chemotherapy with or without granulocyte colony-stimulating factor (G-CSF) in patients with small cell lung cancer. The authors report a case of a patient who had bullous pyoderma gangrenosum at the site of previous eczema during treatment with G-CSF. The lesions resolved promptly when the drug was discontinued. Other investigators have recently reported inflammatory complications of G-CSF and granulocyte-macrophage colony-stimulating factor (GM-CSF) but this is the first case report of biopsy-proven neutrophilic dermatosis associated with administration of a hematopoietic growth factor. Patients should be monitored for development of inflammatory processes during G-CSF therapy and this therapy should be given with caution to those patients with existing inflammatory conditions.

Pyoderma gangrenosum involving the eyelid.

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.

Juvenile gangrenous vasculitis of the scrotum: Is it a variant of pyoderma gangrenosum?

Juvenile gangrenous vasculitis of the scrotum was described by Piñol et al in 1974 as a unique variant of scrotal gangrene of unknown origin, occurring exclusively in young individuals. It was characterized by an acute onset of skin ulcers undergoing complete resolution after appropriate therapy, with no relapses. We present a typical case of this extremely rare disease affecting a 16-year-old boy in whom the scrotal ulcerations were preceded by an episode of pharyngitis with fever. The condition promptly regressed after administration of intramuscular betamethasone in combination with oral ciprofloxacin. According to Piñol et al, juvenile gangrenous vasculitis of the scrotum, although poorly known to dermatologists, should be regarded as a distinctive entity within the wide group of scrotal gangrenes. On the other hand, the hypothesis that this condition may well represent a variant of pyoderma gangrenosum is discussed.
