We report a case of a 54-year-old female diagnosed with HIV and antiretroviral therapy (ART) for the same. Seven years ago, she suffered from fever, cough and weight loss, was diagnosed with pulmonary tuberculosis and also seropositive for HIV. She suffered from Herpes Zoster infection, after which her ART regimen was changed to TLD (tenofovir, lamivudine and dolutegravir). The patient presented with two episodes of pyoderma gangrenosum (PG), which were biopsy-proven, corresponding to a rise in CD4 counts above 500. She responded to glucocorticoids, both systemic and topical.

Exertion and exercise increase glucose metabolism within the skeletal muscles causing increased fludeoxyglucose (FDG) uptake on F-FDG positron emission tomography/computed tomography (PET/CT). Here, we present findings of F-FDG PET/CT in a patient with acute viral hepatitis A-induced liver failure with multiple foci of pyoderma and incessant itching resulting in increased FDG uptake in the muscles of the bilateral forearm, producing the "bilateral hot forearm sign."

Skin lesions in chronic lymphocytic leukemia (CLL) have been reported in between 4% and 20% of patients with CLL and are a rare entity compared with T-cell leukemia. They can present mainly as leukemic cutis or, frequently, as secondary lesions such like urticaria, itching, pyoderma gangrenosum, cutaneous vasculitis, Sweet's syndrome, and erythroderma. We report on an adult patient who developed a skin lesion of forearms and hands, leading to the discovery of isolated cutaneous CLL after two biopsies. Isolated CLL cutaneous location is very rare and may be diagnosed late, as in the case of our patient. A better knowledge of the course of the illness and rapid diagnosis of this CLL cutis leukemia will enhance the therapeutic efficacy of the disease.

Review
Staphylococcus pseudintermedius is one species in the commensal staphylococcal population in dogs. While it is commonly carried on healthy companion dogs it is also an opportunistic pathogen associated with a range of skin, ear, wound and other infections. While adapted to dogs, it is not restricted to them, and we have reviewed its host range, including increasing reports of human colonisation and infections. Despite its association with pet dogs, S. pseudintermedius is found widely in animals, covering companion, livestock and free-living species of birds and mammals. Human infections, typically in immunocompromised individuals, are increasingly being recognised, in part due to improved diagnosis. Colonisation, infection, and antimicrobial resistance, including frequent multidrug resistance, among S. pseudintermedius isolates represent important One Health challenges.

While Pyoderma gangrenosum (PG) is commonly associated with hematological disorders such as acute myeloid leukemia (AML), it typically presents concurrently with the hemopathy, mostly in its bullous form, among middle-aged individuals. Here, we report the unusual case of a young female patient who presented with PG in its ulcerative form, three weeks before the onset of AML. A 31-year-old female presented with a one-week history of painful perianal papulopustule that evolved into an irregular ulceration with violaceous borders, mucopurulent serosity, and erythematous surrounding skin. Laboratory work-up demonstrated elevated inflammatory markers and hyperleukocytosis, with no cytopenia, and normal peripheral blood smear. Two weeks later, the ulcer growth was noted with a similar ulceration at a venipuncture site. A complete blood count revealed pancytopenia, with 45% blasts on the peripheral blood smear. Skin biopsies showed an aseptic neutrophilic infiltrate in favor of PG. Intravenous methylprednisolone was administered with rapid resolution of the lesions. However, the patient died shortly after. The post-mortem results of bone marrow aspirate revealed AML, with immunohistochemistry of the skin lesions confirming the clonality of neutrophils derived from the leukemic clone. This case highlights a distinctive clinical presentation, illustrating the manifestation of PG three weeks before the onset of AML in its ulcerative rather than bullous form, in a young female patient.

Pyoderma gangrenosum (PG) is an extremely rare case of sterile necrotic ulcerative disease associated with malnutrition as a predisposition factor. It is unclear, though, whether dilated cardiomyopathy, which affects blood flow and results in stenosis in the arteries, could play a role as an etiology. In this study, a case of pyoderma gangrenosum in a 10-year-old boy complicated by dilated cardiomyopathy, a previous history of cerebrovascular disease, and a malnourished condition were reported. The patient was reported to have exudative necrotic lesions in both legs. Lesions began as small, multiple, itchy lesions on both legs, which later became blisters and scuffed, and progressed into painful, peeled-off lesions with pus, bleeding, redness around lesions, and maggots within a month. A high fever was an accompanying symptom. The multidisciplinary team was involved to provide a comprehensive treatment for this patient. Antibiotics and necrotomy debridement were performed several times. Anticoagulant treatment was indicated as the coagulation markers were increased and echocardiography suggested thrombus in the left ventricle. The underlying condition that increases the risk of pyoderma gangrenosum should be corrected. The patient was discharged after a clinical improvement, although the continuation of outpatient monitoring was required. Our report suggests that a chronic condition of dilated cardiomyopathy that affects normal blood flow leads to malnutrition, the formation of thrombus, and stenosis of a peripheral artery, all of which contributed to pyoderma gangrenosum. Therefore, early surgical treatment, antibiotic administration, and anticoagulant treatment were recommended.

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis causing chronic and recalcitrant painful ulcerations. Pathogenic mechanisms are yet poorly understood limiting therapeutic options, however, IL-12/IL-23 inhibition via ustekinumab has previously been associated with positive outcomes. We aimed to elucidate the dysregulated immune landscape of PG and lesional skin changes associated with IL-12/IL-23 blockade. We applied spatial transcriptomics and comparative computation analysis on lesional biopsies from two patients obtained before and after IL-12/IL-23 blockade with ustekinumab. Our data indicate lesional PG skin exhibits complex patterns of inflammation, including a not previously described major infiltration of B cells and establishment of tertiary lymphoid structures. In both patients, IL-12/IL-23 blockade led to marked clinical improvement but was associated with amelioration of contrasting inflammatory pathways. Notably, plasma cell markers and tertiary structures were recalcitrant to the treatment regime suggesting that B cells might play a role in the refractory nature of PG.
