We report a Caucasian female who presented with simultaneous erythema nodosum and pyoderma gangrenosum due to underlying Takayasu's arteritis. Takayasu's arteritis is a chronic large vessel vasculitis of unknown cause. The disease has a worldwide distribution but is most commonly seen in Asian populations. There is a strong predilection for young females. The clinical presentation is variable, but mostly derives from stenosis or occlusion of affected arteries, resulting in claudication and ischemia. Skin manifestations are observed in up to 28% of patients with Takayasu's arteritis, with erythema nodosum reported more frequently in Caucasians...

A female patient with a critical soft tissue defect after elective knee replacement surgery was transferred to our department for reconstruction. As wounds were rapidly progressing, necrotizing fasciitis was initially suspected but eventually ruled out by histopathological analysis. A 50 × 15 cm defect was then reconstructed by means of a combined Parascapular and latissimus dorsi flap before, a couple days later, the patient developed tender pustules and ulcers involving the flap as well as the donor site...

Skin manifestations are common in patients with inflammatory bowel diseases (IBD) and can be part of a concomitant illness with a shared genetic background, an extra-intestinal manifestation of the disease, or a drug side-effect. Areas covered: We provide a practical overview of the epidemiology, pathogenesis, diagnosis, therapeutic approach and prognosis of the most frequent disease-related and drug-induced cutaneous manifestations in IBD, illustrated by cases encountered in our clinical practice. Among the most frequently encountered IBD-related lesions are erythema nodosum, pyoderma gangrenosum and Sweet's syndrome...

Some cutaneous inflammatory disorders are typified by a predominant or exclusive localization in the dermis. They can be further subdivided by the principal cell types into lymphocytic, neutrophilic, and eosinophilic infiltrates, and mixtures of them are also seen in a proportion of cases. This review considers such conditions. Included among the lymphoid lesions are viral exanthems, pigmented purpuras, gyrate erythemas, polymorphous light eruption, lupus tumidus, and cutaneous lymphoid hyperplasia. Neutrophilic infiltrates are represented by infections, Sweet syndrome, pyoderma gangrenosum, and hidradenitis suppurativa, as well as a group of so-called "autoinflammatory" dermatitides comprising polymorphonuclear leukocytes...

This study aimed to investigate the nasal carriage of methicillin-resistant Staphylococcus pseudintermedius (MRSP) in dogs treated with oral cephalexin monohydrate. Ten dogs with superficial pyoderma were monitored longitudinally for carriage of MRSP for up to 1 year after treatment; the strains were typed and antibiograms were determined. Methicillin-susceptible S. pseudintermedius (MSSP) was recovered prior to treatment in all dogs and could be isolated after 12 months in 1 dog. Methicillin-resistant Staphylococcus pseudintermedius was detected within 1 week of treatment in all dogs, and 3 clones represented by ST45, ST112, and ST181 were consistently present for up to 12 months after treatment...

The immunobiology underlying the slow acquisition of skin immunity to group A streptococci (GAS), is not understood, but attributed to specific virulence factors impeding innate immunity and significant antigenic diversity of the type-specific M-protein, hindering acquired immunity. We used a number of epidemiologically distinct GAS strains to model the development of acquired immunity. We show that infection leads to antibody responses to the serotype-specific determinants on the M-protein and profound protective immunity; however, memory B cells do not develop and immunity is rapidly lost...

Primary cutaneous anaplastic large cell lymphoma (pcALCL) forms 9% of the cutaneous T-cell lymphomas. It usually presents as solitary reddish brown ulcerating nodule or indurated plaque. Sometimes, it mimics other dermatological diseases such as eczema, pyoderma gangrenosum, pyogenic granuloma, morphea, and squamous cell carcinoma. Our case presented with large pyogenic granuloma like lesion with regional lymphadenopathy. Since pcALCL is rare, one can misdiagnose such cases and therefore high index of suspicion is necessary...

BACKGROUND: Pyoderma gangrenosum (PG) is a rare, severe, destructive neutrophilic dermatosis characterized by a progressive, necrotizing process after skin injury. Its cause is still unknown, and diagnosis represents a challenge when ulcers are seen after surgery. Bacterial infection is not found in the wounds. Patients exhibit "pathergy" with the appearance of new lesions after local trauma such as surgical procedures, debridements, and wound care, suggesting altered inflammatory response...

Fur Animal Epidemic Necrotic Pyoderma (FENP) is a severe, often lethal infectious disease affecting all three fur animal species: mink (Neovision vision), foxes (Vulpes lagopus) and finnraccoons (Nyctereutes procyonoides). Previous studies showed an association between Arcanobacterium phocae and FENP. An experimental infection was conducted to confirm the ability of A. phocae to infect mink either alone or concurrently with a novel Streptococcus sp. found together with A. phocae in many cases of FENP. Different inoculation methods were tested to study possible routes of transmission...

BACKGROUND: Pyoderma gangrenosum (PG) is a rare skin disease characterized clinically by ulcers with undermined borders, and histologically by neutrophil-rich infitrates. PG may occur alone, in syndromic forms or associated with systemic diseases as inflammatory bowel diseases and hematological or rheumatological disorders. OBJECTIVES: Although some autoinflammatory diseases present with PG, to date, a specific genetic background related to autoinflammation has not been proven for PG...

BACKGROUND: Post Surgical Pyoderma Gangrenosum (PSPG) is a neutrophilic dermatosis causing aseptic necrotic ulcerations within surgical sites. It is often misdiagnosed as infection or ischemia and worsened by the inappropriate treatment. Therefore diagnostic clues must be identified and awareness for PSPG raised. METHODS: We present two cases of PSPG after flap surgery and a review of the literature. RESULTS: Seventeen cases of PSPG after flap surgery were found...

BACKGROUND: The emerging skin disease fur animal epidemic necrotic pyoderma (FENP) has been attributed to infection with Arcanobacterium phocae (ABP). The exact pathogenesis and risk factors of FENP have yet to be elucidated. ANIMALS: Three mink from each of three different mink farms (A-C) with postvaccination skin wounds at the vaccination site and six mink from an unaffected mink farm (D) that had used the same vaccine batch and vaccination site (hind leg). METHODS AND RESULTS: All minks from farms A-C had severe necrotizing to necropurulent dermatitis where they were vaccinated intramuscularly in the hind leg...

BACKGROUND: Pyoderma gangrenosum (PG) is an uncommon, ulcerative, cutaneous condition, often caused by surgical trauma that can masquerade as a pyogenic disease process requiring debridement and antibiotics. Treatment is, however, medical, with delay leading to significant morbidity. In addition, medical workup for coincident disorders has been suggested. The purpose of this study was to test the hypothesis that pediatric PG has differing disease associations and therefore requires a differing medical workup...

Multiple myeloma (MM) is a proliferative disorder of plasma cells which produce abnormal immunoglobulin proteins. Skin involvement is rarely found in this disorder. They are either specific or nonspecific lesions. We report four such interesting patients who presented to us initially with common dermatoses such as leukocytoclastic vasculitis, pyoderma gangrenosum, and vesiculobullous disorders and were subsequently diagnosed to have MM. There were no skeletal involvements or renal function abnormality at the time of presentation...

BACKGROUND: Pyoderma gangrenosum is a rare, ulcerative, destructive, non-infectious dermatologic disease and it is one clinical entity within the spectrum of neutrophilic dermatoses. Visceral involvement, manifesting as sterile neutrophilic infiltrates in sites other than skin and, is infrequent. Splenic involvement is very rare. MAIN OBSERVATIONS: We present a case of a 58-year-old woman with pyoderma gangrenosum with spleen involvement and review all reports of similar cases...
