BACKGROUND: Sweet syndrome is a neutrophilic dermatosis that may be categorized into classic, malignancy-associated, and drug-induced subtypes. Few studies have systematically analyzed this rare disorder. OBJECTIVE: To describe the clinicopathologic characteristics and treatment of Sweet syndrome and identify characteristics associated with concurrent malignancy. METHODS: We retrospectively reviewed patients with Sweet syndrome at the University of Pennsylvania from 2005 to 2015...

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...

Sweet syndrome (acute, febrile, neutrophilic dermatosis) is characterized by the acute onset of an eruption of painful nodules or erythematous or violaceous plaques on the limbs, face and neck. These symptoms are accompanied by fever. The diagnostic features include histopathological findings of dermal neutrophilic infiltration without leukocytoclastic vasculitis or peripheral blood leukocytosis. Sweet syndrome is associated with infection, malignancies, autoimmune disease, pregnancy, and drugs. Patients with Sweet syndrome demonstrate a complete and rapid response to systemic steroid administration...

Histiocytoid Sweet's Syndrome is a rare inflammatory disease described in 2005 as a variant of the classical Sweet's Syndrome (SS). Histopathologically, the dermal inflammatory infiltrate is composed mainly of mononuclear cells that have a histiocytic appearance and represent immature myeloid cells. We describe a case of Histiocytoid Sweet's Syndrome in an 18-year-old man. Although this patient had clinical manifestations compatible with SS, the cutaneous lesions consisted of erythematous annular plaques, which are not typical for this entity and have not been described in histiocytic form so far...

Importance: Histiocytoid Sweet syndrome is a rare histopathologic variant of Sweet syndrome. The nature of the histiocytoid infiltrate has generated considerable controversy in the literature. Objective: The main goal of this study was to conduct a comprehensive overview of the immunohistochemical phenotype of the infiltrate in histiocytoid Sweet syndrome. We also analyze whether this variant of Sweet syndrome is more frequently associated with hematologic malignancies than classic Sweet syndrome...

We present an original case report of a 58-year-old man with a history of histiocytoid Sweet and myelodysplastic syndrome who presented with a new onset of tender plaques on his oral commissures. A biopsy revealed a dense dermal neutrophilic infiltrate, leukocytoclasis without frank vasculitis, and, most notably, the presence of many xanthomatized cells. Clinical presentation and histologic features were most consistent with an acute neutrophilic dermatosis, which we believe to be a xanthomized variant of Sweet syndrome...

A number of neutrophilic dermatoses are associated with malignancies and their treatment. These rarely occur together in the same patient. A Caucasian 72-year-old male was treated for acute myeloid leukemia (AML) with chemotherapy including daunorubicin and cytarabine. Within 48 hours of commencing treatment, he developed pyrexia and, two days later, disseminated non-tender pink plaques on the limbs and trunk. A skin biopsy showed a dermal interstitial infiltrate of lymphocytes, histiocytoid cells and predominantly neutrophils...

Autoimmune hepatitis is a subtle diagnosis that has many diverse clinical presentations. It has been reported in the literature to occur concomitantly with pyoderma gangrenosum, a neutrophilic dermatosis. Sweet's syndrome is another neutrophilic dermatosis and has been reported to be associated with autoimmune hepatitis in only 2 previous cases: 1 idiopathic and 1 drug induced. Here we report a third case in a 24-year-old woman diagnosed with Sweet's syndrome in association with autoimmune hepatitis, documenting a possible trend between neutrophilic dermatoses and autoimmune hepatitis...

Histiocytoid Sweet syndrome (H-SS) is a histological variant of Sweet syndrome (SS) differing from classical neutrophilic SS (N-SS) by a dermal infiltrate mainly composed of lymphocytes and histiocytoid myeloperoxidase-positive cells. We aimed to report a large series of H-SS and compare the frequency and type of hematological malignancies associated to H-SS and N-SS. We included 62 patients with a coding histopathologic diagnosis of SS prospectively registered between 2005 and 2014 in the database of our Department of Pathology...

The neutrophilic dermatoses are a group of disorders characterized by skin lesions for which histological examination reveals intense epidermal and/or dermal inflammatory infiltrates composed primarily of neutrophils without evidence of infection. The myelodysplastic syndromes consist of a heterogeneous group of malignant hematopoietic stem cell disorders characterized by dysplastic and inadequate blood cell production with a variable risk of transformation to acute leukemia. Rarely, histiocytoid Sweet's syndrome occurring in patients with myelodysplastic syndrome has been described...

Sweet syndrome (SS) was described over 50 years ago as a distinctive form of neutrophilic dermatosis. It may be idiopathic, drug-induced or paraneoplastic, and in the last of those subtypes, myeloproliferative diseases are prominently represented. A peculiar variant of SS is termed 'histiocytoid' SS (HSS), and early accounts of that condition asserted that it showed no linkage to hematological disorders. We herein report two additional cases of HSS--both of which were associated with myeloid dyscrasias--together with a review of the pertinent literature...

Histiocytoid Sweet syndrome (HSS) is a rare histologic variation of Sweet syndrome (SS) predominantly exhibiting mononuclear histiocytoid cells instead of neutrophils. We report a 22-year-old woman with HSS, who, after minimal improvement with colchicine and dapsone, had significant improvement of her cutaneous eruption and systemic symptoms following empiric treatment with azathioprine. Since azathioprine has historically been known to cause SS, this case highlights a previously unreported treatment response for the histiocytoid variant...

BACKGROUND: Histiocytoid Sweet's syndrome was originally described as cutaneous lesions of Sweet's syndrome where the infiltrate is mostly composed of histiocytoid mononuclear cells. The putative cell has been interpreted as an immature neutrophil based on the intense expression of myeloperoxidase. METHODS: To better understand the nature of the infiltrate and potential mechanisms leading to this distinct form of cutaneous inflammatory cell influx, thirteen cases of histiocytoid Sweet's syndrome, encountered in the routine and consult practice of one of the authors, were studied...

Sweet syndrome (SS) is an acute febrile neutrophilic dermatosis. It has been associated with malignant disease, especially acute myeloid leukaemia (AML), infections, autoimmune disorders and drugs, particularly granulocyte colony-stimulating factor (GCSF). No cause is found in the rest, which are labelled idiopathic. We describe 15 patients with SS, which we believe represent 'immune dysregulation' secondary to myelodysplastic syndrome (MDS). We initially identified 31 patients with SS in a cohort of 744 patients with MDS and 215 with AML seen over a 6-year period (2004-10)...

BACKGROUND: Histiocytoid Sweet syndrome is an uncommon variant in which the dermal infiltrate is composed of mononuclear cells with a histiocytic appearance that represent immature myeloid cells. Giant cellulitis-like Sweet syndrome is a recently described variant characterized by relapsing widespread giant lesions. PURPOSE: We report a unique patient with histiocytoid giant cellulitis-like Sweet syndrome and review the current literature on histiocytoid Sweet syndrome and giant cellulitis-like Sweet syndrome...
