Therecan be single or multiple lesions, which typically pre-sent cribriform scarring pattern.2 The pathergy phe-nomenon has been frequently described associated tothe infection, in regards to the development of newlesions or worsening of pre-existing lesions after dif-ferent types of trauma, such as debridement, intrader-mal injections, vaccinations, or surgical scars. Thisphenomenon is found in up to 50% of patients.3S310 Batista MD, Fernandes RL, Rocha MAD, Ikino JK, Pinheiro RF, Chauffaille MLLF, et al.An Bras Dermatol. 2006;81(5 Supl 3):S309-12.pustules, vesicles containing blood, ulcerative andvegetative lesions with undermined borders (the lar-gest measuring five centimeters in diameter) and irre-gular scars. The lesions were located on the chest andupper limbs (Figures 1 and 2), including the palms.He presented no adenomegaly or hepatosplenome-galy upon examination. A biopsy of the lesion was performed, and thepathological examination was characterized by diffu-se chronic dermatitis in acute phase (Ziehl-Neelsen,PAS and direct immunofluorescence were negative),which was compatible with unspecific chronic ulcer.Another biopsy was perfortmed and the outcome wasulcerated suppurative chronic inflammatory processwith granulation tissue (absence of granulomas, andLeishmania test was negative) (Figure 3). With a suggestive clinical picture and rulingout differential diagnoses by pathological examina-tion and other tests (serology for syphilis, HIV, HTLV,leishmaniasis, bacterioscopy for mycobacteria on thelesion and acid-fast bacilli in lymph – all tests werenegative), the presumptive diagnosis was bullouspyoderma gangrenosum. The patient was submittedto neoplasm screening since pyoderma gangrenosumis usually present as paraneoplastic syndrome. In May 2003, the investigation was interruptedbecause the patient suffered an acute myocardialinfarction and underwent left ventricular aneurys-mectomy. The cardiac condition evolved satisfactorilybut he developed a crusty erythematous lesion on theupper portion of the thoracotomy scar.Resuming the investigation, general tests wereconducted, including complete blood count, whichshowed bicytopenia (normocytic/normochronic ane-mia and leukopenia), and proteinogram that showeddysproteinemia (immunoglobulins A, G and M aboveAtypical clinical forms of the disease were also descri-bed, such as chronic vegetative, bullous, peristomaland vulvar lesions.4 Bullous pyoderma gangrenosum(BPG) is characterized by aggressive, painful lesionswith superficial vesicles that rupture to form typicalulcerations with undermined borders.5 While classi-cal PG is more frequently located on the lower limbs,the bullous variant occurs chiefly on the upperlimbs.3The diagnosis of PG is made by exclusion, andit is necessary to investigate other causes of ulcerousdiseases, such as bacterial infections, mycobacterio-ses, vascular insufficiency, vasculitis, halogen-deriveddermatosis, neoplasms and factitial dermatitis.6Histopathological findings of PG are not specific,encompassing areas with abscess,  areas with neutro-philic and lymphocytic infiltrate, and with moderatevasculitis with fibrinoid necrosis.7 In BPG, there is dif-fuse neutrophilic dermatosis without primary vasculi-tis.3 Direct immunofluorescence showed positiveperivascular pattern for antiC3 antobody in 83% ofcases, for antiIgM in 78%, for antiIgA in 14% and forantiIgG in 11% of cases.4The association between PG and systemicdiseases occurs in 50 to 75% of patients. The mostfrequently associated diseases include inflammatorybowel diseases, hematological neoplasias and rheu-matoid artritis.7PG associated to hematological disorders canpresent atypical clinical characteristics, and the asso-ciation with leukemia and myelodysplastic syndrome(MDS) in the bullous form is frequently described.5Up to 54% of the reported cases of PG associated withleukemia were of the bullous subtype.8 The outbreakof BPG can be an indication of reserved prognosis inthese diseases.5The case reported shows the association bet-ween PG, especially the bullous variant, and MDS, ofthe refractory cytopenia with multilineage dysplasiasubtype (RCMD). In these cases, PG is the cutaneousmarker of the systemic disease with unfavorable diag-nosis.CASE REPORTA male patient, 60 years-old, mullato, born andliving in the city of Campos Sales, State of Ceará, mar-ried, farmer, was refered to the Dermatology Serviceof Hospital Sao Paulo in March 2003, complaining ofskin lesions for one year. He complained of mild painon the lesion site. According to the patient, thelesions were intermittent, and they receded sponta-neously leaving a scar. He denied fever, nocturnalsudoresis and gastrintestinal symptoms, as well as theuse of drugs. The dermatological exam showedlesions in different phases: erythematous papules,FIGURE 1: Ulcers with granulation tissue andundermined borders on the chestFIGURE 2:Lesions at dif-ferent deve-lopment sta-ges: ulcerati-ve and vege-tative lesionswith under-mined bor-ders, ulcerati-ve and crustylesions andirregularscars on thechest andupper limbsnormal limits). The myelogram showed hypercellularbone marrow with dysplasia in over 50% of cells fromthe erythrocytic and granulocytic series, which iscompatible with RCMD, according to the WorldHealth Organization (WHO) classification.9 A biopsyof the bone marrow revealed dysplastic alterationsand increased early granulocytic cells in the center ofintercellular spaces (Figure 4), associated to increa-sed CD34 expression in the immunohistochemicaltest (Figure 5). A G-band kariotyping showed 46 XY[20][?]. The patient initiated treatment for the skincondition with dapsone, 100mg per day, and thelesions healed 45 days later. A multidisciplinary fol-low-up will be conducted due to the risk of evolvingto myeloid leukemia.DISCUSSIONMyelodysplastic syndromes (MDS) are clonalhematological disorders clinically and morphologi-cally characterized by ineffective hematopoesis. Theycan present chronic course, lasting a few years, or suf-fer leukemic transformation, which occurs in 40% ofcases.10 They are associated with auto-immune mani-festations, such as thrombocytopenic purpura, vascu-litis, chronic inflammatory demyelinating polyneuro-pathy and PG, which occurs in 10 to 13.6% of cases.These auto-immune manifestations represent a signi-ficant cause of morbidity and mortality, and are asso-ciated with poorer prognosis.11 The average survivalafter diagnosis of MDS is 25 months; if auto-immunemanifestations occur, it drops to nine months.

The pathogenesis of the relation between PGand hematological disorders remains unclear.  MDSwould cause alterations in antigen presentation, in T-cell response or in the interaction between T and Bcells, leading to an immune system imbalance,12which would lead, in turn, to production of auto-anti-bodies against cutaneous antigens with perivascularimmune complexe deposition.13 PG can occur conco-mitant to the hematological disease or, during its evo-lution, as marker of the malignant transformation ofa previously stable disease.8As in the case reported, PG can be the cuta-neous manifestation of a systemic disease. The possi-bility of MDS should always be considered in patientswith pyoderma gangrenosum presenting by mono-,bi- or pancytopenia.
