Abstract: Six cases of pyoderma gangrenosum encountered with in a period of 2 years are described here with their clinical presentations and associations. Three patients were cases of superficial granulomatous pyoderma and three were of ulcerative type. Rheumatoid arthritis was found to be the associated disease in one of the cases of ulcerative type. Response to therapy was satisfactory in all of them expect in one case of ulcerative pyoderma gangrenosum who was resistant to most of the available therapeutic modalities.

Indian Journal of Dermatology, Venereology and Leprology , 2004,
Abstract: Pyoderma gangrenosum is a neutrophilic dermatosis with distinctive clinical manifestations. It is frequently associated with systemic diseases like inflammatory bowel disease, rheumatoid arthritis and myeloproliferative diseases. The etiopathogenesis of pyoderma gangrenosum is still not well understood. Clinically it is classified into ulcerative, pustular, bullous and vegetative types. The diagnosis mainly depends on the recognition of evolving clinical features as there are no specific investigations for the diagnosis. It is essential to exclude other infectious diseases before therapy is initiated as corticosteroids and immunosuppressant therapy are the mainstays in the treatment of this disease. Recently, drugs like tacrolimus, mycophenolate mofetil and infliximab have shown promising results in this condition. Recent concepts regarding the various types of pyoderma gangrenosum and its management are reviewed.

Marcos Martins Curi, Camila Lopes Cardoso, Daniel Henrique Koga, Cristina Zardetto, Sérgio Rocha Araújo
Open Journal of Stomatology (OJST) , 2013, DOI: 10.4236/ojst.2013.32026
Abstract:

Pyoderma gangrenosum is a rare ulcerative cutaneous disorder commonly associated with systemic diseases such as inflammatory bowel diseases. This paper reports a case of pyoderma gangrenosum affecting the mouth and the skin associated with ulcerative colitis. A Medline search in English literature from 1961 to 2012 revealed only 11 documented cases of pyoderma gangrenosum with oral involvement. Previous reported cases of oral cavity involvement have shown that the most common sites of manifestation are the tongue, palate, and tonsillar fauces. This case emphasizes the importance of including inflammatory bowel diseases and their manifestations in the differential diagnosis of ulcerative lesions in the oral cavity.

Abstract: pyoderma gangrenosum is a rare inflammatory skin condition, characterized by progressive and recurrent skin ulceration. there may be rapidly enlarging, painful ulcers with undermined edges and a necrotic, hemorrhagic base. disorders classically associated with pyoderma gangrenosum include rheumatoid arthritis, inflammatory bowel disease, paraproteinemia and myeloproliferative disorders. there have been some reports of the occurrence of pyoderma gangrenosum in africa, and in nigeria, but only one specifically reported pyoderma gangrenosum in association with ulcerative colitis. we report on a 45-year-old man who presented with pyoderma gangrenosum associated with ulcerative colitis; the second report in nigeria. the skin lesions were managed with daily honey wound dressings. oral dapsone and prednisolone were started. the frequency of the bloody diarrhea decreased, and was completely resolved by the second week after admission. the ulcers also showed accelerated healing. the goal of therapy is directed towards the associated systemic disorder, if present.

Indian Journal of Sexually Transmitted Diseases , 2009,
Abstract: Retroviral infection is known to cause varied manifestation of any disease. We report a 27-year-old female who presented with non-healing painful ulcer in the left hand of 6 months′ duration. The patient was diagnosed as pyoderma gangrenosum and treated with immunosuppressant drugs. One month later, she developed perianal vesicles and Tzanck smear from the vesicles showed multinucleated giant cells. A workup for sexually transmitted disease revealed HIV 1 Elisa to be positive. Diagnosis of herpetic ulcer was made and treated with famciclovir and hand ulcer gradually healed in 25 days. We report this case to highlight the occurrence of herpetic ulcer in an unusual site in a HIV patient and may lead to misdiagnosis of pyoderma gangrenosum
Pyoderma gangrenosum in childhood  [cached]

Abstract: We have treated 4 cases of pyoderma gangrenosum in infancy and childhood in past 2 years. The ages at onset were 6 months, 8 months, 6 months and 11.5 years respectively. Initial lesions were papulopustular in 3 and nodular in 1 patients but later on all of them developed ulcerative lesions with erythematous, violaceous, infiltrated or undermined edges. The lesions were numerous in 3 patients but few in 1 patient. The first patient had very high leucocyte count. In the second patient skin lesions of PG followed measles vaccinations. We could not reveal any association in the other two patients. None of the patient responded to antibiotic therapy. Three patients were treated successfully with dapsone and one with a combination of dapsone and prednisolone. We conclude that pyoderma gangrenosum is not so rare in infancy and it is more likely to occur without associated systemic diseases.

Abstract: A 21-year-old female presented with erythematous, painful, crusted plaques on her right arm and left thigh of 4 month's duration. There was no history of preceding trauma or constitutional symptoms. Response to oral antibioticas was poor. Clinical differential diagnoses of pyoderma gangrenosum (PG) and granulomatous skin diseases such as deep fungal infection, lupus vulgaris and sarcoidosis were considered. Histopathology revealed features of granulomatous variant of PG. The patient was initially treated with dapsone and topical clobetasone propionate but she developed dapsone induced hepatitis and anemia warranting stoppage of the drug. She recovered completely from these side effects and was subsequently treated successfully with intralesional triamcinolone injections.
