We report a 58-year-old patient with acute myeloid leukaemia who developed an oedematous erythema resembling Sweet's syndrome, accompanied by atypical erythema nodosum and bullous pyoderma gangrenosum. Examination of skin biopsies showed dense infiltration with mature neutrophils, although there was peripheral blood leucocytopenia. The oedematous erythema worsened after he was treated with granulocyte-colony-stimulating factor (G-CSF), which was given for his leucocytopenia. We suggest that when a neutrophilic dermatosis complicates leukaemia, alternatives to G-CSF should be considered for the treatment of leucocytopenia. Corticosteroids were very effective in controlling the skin lesions in our patient.

Pyoderma gangrenosum is a neutrophilic dermatosis of unknown aetiology. Visceral involvement by pyoderma gangrenosum is rare, the lung being the most frequent site of extracutaneous disease. We describe a 73-year-old man with pyoderma gangrenosum and chronic myelomonocytic leukaemia in whom aseptic hepatosplenic abscesses and bony lesions were associated.

Bullous pyoderma gangrenosum is an atypical, more superficial variety of the classical pyoderma and is often associated with myeloproliferative disorders. We present the case of a patient who presented initially with subcutaneous nodules and who developed bullous lesions afterwards. Histological evaluation showed the presence of neutrophilic infiltrates in both lesions. A few months after the diagnosis of bullous pyoderma gangrenosum, an underlying leukemia was revealed. Our case illustrates the importance of regular blood and bone marrow examinations in patients with atypical bullous pyoderma gangrenosum, resulting in a rapid diagnosis of the underlying disease.

The authors present the case of a 67-year-old patient in whom bullous pyoderma gangrenosum was the first symptom of acute myeloid leukemia. Histologically leukemic cells were found in the skin infiltrate, on the basis of which this lesion satisfied the criteria of leukemia cutis. It was underlined that in the background of such atypical bullous cases there are often hemoblastoses or their malignant transformation. Finally the connection between bullous pyoderma gangrenosum and atypical vesiculous Sweet syndrome is discussed.

We report a case of atypical bullous pyoderma gangrenosum associated with acute myeloid leukaemia in which we found atypical myeloid cells within the skin lesion. Although there have been many reported cases of leukaemia-associated pyoderma gangrenosum, the finding of myeloblasts in the skin has rarely been described.

We describe the successful treatment of pyoderma gangrenosum (PG) that developed in a patient with myelodysplastic syndrome (MDS). A 63-year-old Japanese man with MDS was admitted to our hospital because of a large skin ulcer on his neck in November 2001. The initial diagnosis was infectious dermatitis, and antimicrobial therapy was performed, using imipenem/cilastatin, isepamicin, and amphotericin B. However, this therapy was not effective, and the lesion worsened. Cultures of blood, throat swab, and ulcer pus yielded no microorganisms. A biopsy of the skin lesion revealed a severe infiltration of neutrophils in the dermis, without any evidence of infection. The lesion was finally diagnosed as PG, and systemic administration of corticosteroid hormone was started in December 2001. The patient was initially pulsed with 1 g methylprednisolone daily for 3 days. The dose was immediately reduced, and the treatment was maintained with 30 mg prednisolone daily. The skin lesion responded markedly to the therapy, and C-reactive protein became negative. The patient was discharged in February 2002 because the lesion was almost cured. Prednisolone administration was tapered after 6-month maintenance therapy. No recurrence of PG was seen, although his MDS transformed into leukemia in April 2003. Only 31 cases of MDS developing PG have been reported in the past 20 years in Japan. This report describes one such rare patient who was successfully treated with the use of high-dose pulse methylprednisolone and long-term maintenance therapy.

An isolated foot ulcer developed in a child with newly diagnosed acute mixed lineage leukemia during induction chemotherapy. Despite its clinical resemblance to pyoderma gangrenosum, herpes simplex virus infection was eventually diagnosed on histopathology. Treatment with oral acyclovir was ineffective, but the ulcer healed with intravenous acyclovir followed by oral valaciclovir. Viral infection remains an unusual but important cause of isolated extragenital cutaneous ulceration in the immunocompromised child.

Ulcerative colitis is an inflammatory bowel disease often associated with extra-intestinal manifestations, such as dermatological disorders. Of these, the most frequent are erythema nodosum and pyoderma gangrenosum, the two neutrophilic forms of dermatosis. Another is Sweet' s syndrome, which results in a sudden eruption of tender, raised erythematous or violaceous plaques/papules or nodules, less frequent vesicles, pustules or bullae, involving face, neck, arms and trunk. This skin disorder is frequently observed in patients with leukaemia or connective tissue diseases, while it is very rare in patients with inflammatory bowel disease. The present report deals with the case of a febrile diffuse skin eruption in a 53-year-old patient with moderately active ulcerative colitis after few days' treatment with steroids and azathioprine. At first, the dermatosis was addressed to an idiosyncrasy to azathioprine, which was, therefore, promptly discontinued. Histological examination of skin biopsies revealed the presence of features typical of a Sweet's syndrome. The eruption gradually improved as well as the patient's general condition, until complete regression was achieved following steroid treatment.

Polycythemia vera is classified with myelogenous leukaemia, agnogenic myeloid metaplasia and primary thrombocythemia as a myeloproliferative syndrome. Cutaneous symptoms have been reported with polycythemia vera, including facial plethora, aquagenic pruritus, urticaria, purpura, Sweet's syndrome and pyoderma gangrenosum. However, polycythemia vera associated with systemic sarcoidosis has been rarely reported. An unusual case of polycythemia vera associated with cutaneous sarcoidosis is described.

The frequency of occurrence of malignant neoplasms in the cases of pyoderma gangrenosum is not exactly determined, but it can be assessed to be at 7%. The aim of the study was to report a 26-year-old male patient with pyoderma gangrenosum coexisting with acute myelogenous leukaemia. The first skin lesions on both tibia occurred in June 2001. Prior to the proper diagnosis of pyoderma gangrenosum, the patient was treated surgically. Because of the dramatic dermatological and general condition in November 2001, the patient was admitted to the Dermatological Department of the Silesian Medical Academy in Katowice where the diagnosis of pyoderma gangrenosum was established. On the clinical and biochemical picture, the diagnosis of pyoderma gangrenosum within acute myelogenous leukaemia was made. Initially, cyclosporin A 200 mg orally per day in the therapy of pyoderma gangrenosum was administered to achieve a slight clinical improvement. Although chemotherapy leukaemia was performed, the patient died after 4 months of the confirmation of the acute myelogenous leukaemia diagnosis.
