The case is presented of a patient with busulfan (Myleran) treated myeloid
leukaemia
, who developed bullous pyoderma gangrenosum. Skin symptoms appeared at the time when treatment was discontinued due to signs of bone marrow depression. The
pyoderma
disappeared following treatment with systemic steroid.

The authors report three personal cases of phagedenic
pyoderma
associated with hemopathy. Studying twenty-five other cases, described in the reviews, the question can be debated on three levels: 1) The clinical characteristics of hemopathic
pyoderma
remain non-specific. However blisters, pustules, and even vegetating lesions occur very often; 2) the etiology of hemopathy is subject to change; acute
leukaemia
or myeloproliferation syndrome. During the polyglobulars associated with
pyoderma
, anemia and myelofibrosis appear quite constantly; 3) finally on the pathogenic level, the recent works tend towards the hypothesis of a damage in the functioning of the polymorphonuclears hence displaying the increase in the inflammation during phagedenic
pyoderma
.

The authors report a case of chronic herpes virus infection of the face which developed in a 70-year old man already affected with chronic lymphocytic leukaemia of the B-cell type (CLL-B) with specific cutaneous localisations. Immunodepression was indicated only by marked hypogammaglobulinaemia. Cell-mediated immunity was preserved. The cutaneous lesions of the face were chronic and presented as
pyodermatitis
vegetans. A one-week course of acyclovir administered by intravenous infusion in doses of 5 mg/kg three times a day resulted in rapid and dramatic cure, but this result proved transient, since the virus infection relapsed 2 1/2 months later. The new episode also was successfully treated with a second course of acyclovir. The herpes virus infection had developed only on those skin areas that were specifically affected by the
leukaemia
; after treatment and eradication of the virus, massive lymphocytic infiltration of the dermis persisted in these areas. Involvement of the skin is rare in CLL-B and has been reported mainly in CLL-T. The lesions most frequently encountered are tuberous and papular lesions and infiltrated plaques on the forehead and ears. The
pyodermatitis
vegetans presentation is unusual. The reasons why viral skin lesions develop on those caused by
leukaemia
are unknown.

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.

Clinical applications of flow cytometry to certain diseases of the dog and cat are now possible. The utility of such applications for diagnosis, prognosis and follow-up are illustrated here by a number of examples: feline AIDS resulting from FIV infection, Leukocyte Adhesion Deficiency in Irish setters, deep
pyoderma
in German shepherds, Immune-mediated Thrombocytopenia, canine Systemic Lupus Erythematosus and Leishmaniasis,
Leukemia
and Lymphoma.

We report on two female patients who presented with painful recurrent palpable purpura, ulcers and necroses on the extremities. The results of all examinations and laboratory tests considered together suggested a diagnosis of necrotizing leukocytoclastic vasculitis. Leukocytoclastic vasculitis is an inflammatory necrotizing condition of the superficial dermal vessels, presenting with variable clinical symptoms. In most cases it becomes manifest as palpable purpura, but hemorrhagic-necrotizing, bullous, nodular and urticarial presentations also occur. Common etiological factors include bacterial, viral or drug antigens, chronic infections (hepatitis B and C), non-Hodgkin lymphomas (monoclonal gammopathy, multiple myeloma),
leukemia
(hairy cell leukemia), and tumors (bronchial, breast, and gastric cancer) and also connective tissue disorders. In the course of the work-up, a plasmocytoma was discovered as the cause of the leukocytoclastic vasculitis, presenting in a similar way to livedo reticularis in one case and to
pyoderma
gangraenosum in the other.

Pyoderma
gangraenosum (PG) is a serious chronic, ulcerative skin disorder afflicting both adults and children. As PG is often associated with systemic diseases (>50%) such as inflammatory bowel disease, rheumatoid arthritis or haematological disorders, it requires a multidisciplinary approach. This disorder is not commonly reported in paediatrics; therefore children with PG represent a particularly difficult diagnostic challenge. Clinical diagnosis is often delayed and PG is only considered after eliminating other causes of cutaneous ulcers. We report a 4-year-old boy with secondary myelodysplastic syndrome following treatment for acute lymphoblastic
leukaemia
who presented with a massive inflammatory, ulcerative proliferation of the lower lip which was diagnosed as PG. We have reviewed the literature with reference to diagnostic criteria and treatment options of this disorder that is particularly rare in childhood.

A 5(3/12)-year-old boy with Philadelphia chromosome (+) pre-B acute lymphoblastic leukemia (ALL) without extramedullary involvement did not achieve remission after induction therapy. His family stopped therapy, but he was readmitted eight months later due to
pyoderma
, pneumonia and active
leukemia
with leukocytosis. During cytoreductive and antibiotic therapy, he developed progressive abdominal distension, pain, globe vesicale, tachypnea, and respiratory alkalosis. Bowel sounds could not be auscultated. Dilation, mainly in the large intestine, was detected radiologically. His neurological examination revealed absence of superficial reflexes and hypoesthesia along with normal motor strength and deep tendon reflexes in the lower extremities, consistent with conus medullaris syndrome, which was thought to give rise to acute colonic pseudo-obstruction.

We present a unique case of a 36-year-old male who developed more than 20 pyoderma gangrenosum (PG) ulcers showing on histopathology a dense inflammatory infiltrate composed of histiocytoid mononuclear immature cells with a strong positivity for myeloperoxidase and Leder stain, suggesting a myeloid lineage in the absence of a concomitant myeloproliferative disorder. Histiocytoid Sweet syndrome (SS) is now recognized as a histological subtype of SS. Although PG and SS belong to the spectrum of neutrophilic diseases, to the best of our knowledge, this is the first case of a "Histiocytoid
pyoderma
gangrenosum" encompassing immature granulocytes in the absence of
leukemia
cutis.
