“…10 Saeed et al reported the case of a patient with a history of psoriasis who presented with tender erythematous plaques with a hemorrhagic crust and bullae, leading to the diagnosis of Sweet's syndrome. 8 Additionally, this patient had blood test ndings suggestive of Hashimoto's thyroiditis that improved with steroid treatment. We suggest that a common abnormality in 1 cell function may underlie the occurrence of this autoimmune disease cluster in the present patient.…”

“…We suggest that a common abnormality in 1 cell function may underlie the occurrence of this autoimmune disease cluster in the present patient. 8 Hashimoto's thyroiditis is a 1-mediated disease, 11 and several previous studies have reported the co-occurrence of Hashimoto's thyroiditis and Sweet's syndrome. 12,13 Given that psoriasis is also a prominent 1 cell-mediated disease, 5 in the present case of concurrent psoriasis and Sweet's syndrome, it is possible that these shared characteristics contributed to the onset of both conditions.…”

A Case of Psoriasis Concomitant with Sweet’s Syndrome

Psoriasis often coexists with other skin conditions, which adds to the complexity of patient management. Sweet's syndrome, a rare inflammatory skin disorder, is rarely associated with psoriasis, and its etiology remains elusive. Herein, we present a unique case of Sweet's syndrome in a patient with psoriasis. A 46-year-old man, with a history of psoriasis-like skin lesions treated with an unidentified medication, developed painful erythematous plaques and fever. He was diagnosed with Sweet's syndrome after a skin biopsy. Steroid therapy initially improved the patient's symptoms; however, its discontinuation led to the recurrence of psoriasis-like scaly plaques. An additional skin biopsy confirmed the diagnosis of psoriasis. Complete resolution of the lesions was achieved after 7 months of methotrexate treatment. In conclusion, this is the first reported case of psoriasis concomitant with Sweet's syndrome in Korea, highlighting the importance of recognizing coexisting skin conditions in patients with psoriasis despite their rarity.

“…Relying on the clinical history, we can suppose that AT may be considered the main triggering condition in both cases. An association of Sweet syndrome with AT has been previously reported [ 1 , 2 ]. Neutrophilic urticarial dermatosis on the other hand has been described in association with autoinflammatory diseases, Schnitzler syndrome, adult-onset Still disease, and systemic lupus erythematosus [ 3 ].…”

Neutrophilic Dermatoses in Autoimmune Diseases: Report of Two Cases Associated with Autoimmune Thyroiditis

The term “neutrophilic dermatoses” includes a rare inflammatory pattern characterized by neutrophil-rich cutaneous infiltrate. Both innate and adaptive immune pathways may be involved in neutrophil recruitment. Occasionally, neutrophilic dermatoses may occur in association with autoimmune thyroiditis. Pathogenetic aspects of this autoimmune disorder may elucidate their possible connection. Two exemplificative cases are taken as a pretext for a short review of this topic.

“…In the present case there are two potential causes for secondary Sweet syndrome: autoimmune thyroiditis and treatment with clindamycin. As commented, the association between Sweet syndrome and autoimmune thyroiditis has been scarcely reported (5)(6)(7)(8)(9)(10), always in middle-aged women. It was hypothesized that altered Th1 response could be involved in the association of both diseases.…”

Sweet syndrome in a patient affected by autoimmune thyroiditis and receiving clindamycin

Background. Sweet syndrome may be idiopathic or secondary to malignancy, autoimmune and other related inflammatory disorders, and drugs. Association with autoimmune thyroiditis is uncommon, and only in recent years a possible relationship with clindamycin has been reported. Main observations. A 46-year-old woman diagnosed of hypothyroidism one year earlier was treated with clindamycin for erysipelas affecting both legs. A few days later she became febrile, and plaques, nodules and pustules appeared in the anterior aspect of left hemithorax and shoulder. She was placed on daptomycin and levofloxacin, and erysipelas subsided, but the papulous eruption of the thorax did not, so a biopsy was performed, showing features typical of Sweet syndrome. After a short course of prednisone, 30 mg daily, papules and plaques disappeared. Antithyroglobulin and antithyroid peroxidase antibodies were both positive. Conclusion. This patient developed a Sweet syndrome in the context of an autoimmune thyroiditis, but only shortly after she received clindamycin. In 1993 the first case of autoimmune thyroiditis associated to Sweet syndrome was reported, and only a handful of cases have been reported since then; in 2007, the first case of Sweet syndrome associated to clindamycin was reported, and only one more has been published so far. Despite this, clindamycin does not appear as a drug related to Sweet syndrome in recent reviews on this illness. Temporal relationship favors the hypothesis that clindamycin was the triggering factor of Sweet syndrome in this case. Whether or not the immune alteration associated to thyroiditis also played a role is not known.
