Sweet syndrome, or acute febrile neutrophilic dermatosis, is a rare inflammatory condition characterized by painful erythematous plaques, fever, and neutrophilia. While it is often associated with malignancy or drug reactions, it may also occur following streptococcal infection. This case highlights the importance of early recognition and treatment of Sweet syndrome secondary to streptococcal pharyngitis.

A 44-year-old female presented with painful erythematous papules and nodules on her extremities, neck, and nape, associated with fever and chills. The lesions started as skin-colored papules that rapidly progressed to painful erythematous plaques. Her medical history included a sore throat two weeks prior. Initial management Clindamycin provided temporary relief, but the lesions persisted. Laboratory work revealed neutrophilic leukocytosis, elevated erythrocyte sedimentation rate (ESR), and an elevated anti-streptolysin O titer. A skin biopsy showed diffuse neutrophilic dermatitis with vasculitis, confirming the diagnosis of Sweet syndrome. Subsequent treatment with oral corticosteroids led to significant clinical improvement over a week.

This case illustrates the importance of considering infectious triggers, such as streptococcal infections, in the diagnosis of Sweet syndrome. Early diagnosis and appropriate treatment with corticosteroids are essential in preventing complications. Reporting this case contributes to the understanding of non-malignant triggers of Sweet syndrome and underscores the need for heightened awareness of this rare condition in patients presenting with acute febrile dermatosis.

Sweet syndrome (SS), or acute febrile neutrophilic dermatosis, is a rare inflammatory disorder characterized by fever, painful raised plaques, and dermal neutrophilic infiltration. Pediatric cases account for only 5% of SS globally, and no report exists of SS in infants in the Philippines. This report documents a unique case of SS in a one-month-old male, one of the first documented in the country. The rarity of this condition in infants and its successful management contribute valuable insights into the understanding and treatment of pediatric SS.

A one-month-old male presented with fever, erythematous plaques on the face and extremities, and a rapidly growing nodule on the left lateral neck, along with concurrent fever and cough. Skin biopsy showed dermal neutrophilic infiltration without leukocytoclastic vasculitis, confirming SS. A CT scan revealed a neck abscess and pneumonia. The abscess was treated with incision and drainage, and IV antibiotics. Due to the infection, systemic corticosteroids were contraindicated. Instead, topical hydrocortisone was applied, leading to rapid improvement of the skin lesions. This highlights a successful approach for managing SS when systemic therapy is unsuitable.

This case emphasizes the importance of early diagnosis and individualized treatment in rare pediatric cases of Sweet syndrome. The effective use of topical hydrocortisone in place of systemic steroids demonstrates the potential of alternative therapies, especially when infections preclude standard treatments. This case, one of the first in a neonate in the Philippines, contributes valuable insights to the limited literature on managing this rare condition in infancy.

Sweet's syndrome also known as acute neutrophilic dermatosis is a multisystem inflammatory disorder characterized by fever, malaise, leukocytosis, and skin lesions. Sweet's syndrome affects multiple organs though only rarely does it affect the central nervous system (CNS) when it does it is called Neuro-Sweet disease (NSD). We report on a case study of a biopsy-proven NSD in a 50 year old man. Serial magnetic resonance imaging (MRI) showed repeated CNS involvement of Sweet's syndrome after a respiratory tract infection preceded it. On the MRI, T2 hyperintense lesions occurred at multiple sites and disappeared after steroid therapy.

Neutrophilic myositis is a very rare disease histologically characterized by neutrophil infiltration of muscle tissues. We report a case of a 47-year-old man who presented with acute onset of severe swelling and pain on his left shoulder with high fever. He was initially suspected of having cellulitis, but intravenous antibiotics did not improve his symptoms. Similar swelling and pain then developed on both calves. Investigations with magnetic resonance imaging of the lower legs and muscle biopsy led to a diagnosis of neutrophilic myositis. High dose glucocorticoid dramatically improved his symptoms within days. Clinicians need to be aware of this rare disease as a cause of acute febrile myositis mimicking infection.

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. Recently, a distinct variant of Sweet syndrome was reported, termed “histiocytoid Sweet syndrome”, in which the infiltration of myeloperoxidase-positive histiocytoid mononuclear cells are observed (in contrast to the infiltration of neutrophils). The other clinical features are similar to those of classic Sweet syndrome. Pediatric Sweet syndrome is uncommon, and the histiocytoid type is even rarer. To date, four cases of histiocytoid Sweet syndrome have been reported in children. Herein, we describe a case of histiocytoid Sweet syndrome in an otherwise healthy 10-year-old boy with no underlying systemic disease in whom non-steroidal, anti-inflammatory drug treatment was successful.

Sweet syndrome is a disorder characterized by painful, erythematous, cutaneous plaques and nodules of rapid onset accompanied by fever, leukocytosis, and neutrophilia. We encountered a case of a recurrent histiocytoid Sweet syndrome in a patient with acute myeloid leukemia (AML). A 64-year-old Korean man was diagnosed with complete remission of AML and had symptomatic nodules and plaques on the dorsal sides of both hands. Approximately 3 years prior, he also had symptomatic plaques at the same site and had been diagnosed with MDS (Myelodysplastic syndrome). We performed a biopsy and diagnosed this case as a malignancy-associated histiocytoid Sweet syndrome. Most Sweet syndrome cases are acute; in contrast, this case was chronic with a relapse. In addition, histopathologic examination showed a dense histiocytic infiltration. These histiocytoid cells are usually misinterpreted as histiocytes; however, they are actually immature myeloid cells. Herein, we report a case of a recurrent malignancy-associated histiocytoid Sweet syndrome in a patient with a hematologic disorder.

Sweet's syndrome, or acute febrile neutrophilic dermatosis, occurs in association with autoimmune diseases such as Hashimoto's thyroiditis but is rare in Graves' disease, in which all cases are induced by propylthiouracil (PTU). We report a case of Sweet's syndrome in a patient with Graves' disease treated with methimazole (MMI) during three weeks. A 34-year-old man presented with the acute onset of high fever, skin rashes on the whole body, arthralgia, and acroparesthesia. Laboratory results showed leukocytosis and elevated C-reactive protein. MMI first stopped and antibiotics and antihistamine therapy started, but his symptoms dramatically improved after oral prednisolone. Graves' disease has again been treated by MMI because of his aggravated ophthalmopathy. After one year of retreatment with MMI, there has been no recurrence of Sweet's syndrome, supporting that Sweet's syndrome in this case was not related to MMI exposure. To our knowledge, this is the first report of Sweet's syndrome associated with Graves' disease per se but not PTU or MMI use.
