Scleredema of Buschke associated with difficult-to-control type 2 diabetes mellitus / Escleredema de Buschke associado a diabetes mellitus tipo 2 de difícil controle

SUMMARY Scleredema of Buschke (SB) is a rare disorder of connective tissue characterized by diffuse non-pitting induration of the skin, mainly on the cervical, deltoid and dorsal regions. It is a cutaneous mucinosis of unknown etiology and is associated with bacterial or viral infections, hematological disorders and diabetes mellitus. Histopathological examination shows thickened dermis with wide collagen bundles separated by gaps that correspond to mucopolysaccharide deposits, visualized using special staining. Several treatments are reported in the literature without well-established results. We report a case of SB in a patient with type 2 diabetes mellitus.

RESUMO Escleredema de Buschke (EB) é doença rara do tecido conjuntivo caracterizada por endurecimento difuso e não depressível da pele, principalmente nas regiões cervical, deltoideanas e dorso. Enquadrado no grupo das mucinoses cutâneas, tem etiologia desconhecida e associação com: infecções bacterianas ou virais, alterações hematológicas e diabetes mellitus. O exame histopatológico evidencia derme espessada com fibras colágenas calibrosas separadas por fendas que correspondem a depósito de mucopolissacárides, observados por colorações especiais. Diversos tratamentos são relatados na literatura sem resultados bem definidos. Descrevemos caso de EB em paciente com diabetes mellitus tipo 2.

Scleredema associated with Sjögren’s syndrome

Scleredema adultorum of Buschke is a rare disorder characterized by diffuse swelling and non-pitting induration of the skin usually involving the face, neck, arms and upper trunk. It has been associated with previous infectious diseases, diabetes, paraproteinemia and, more rarely, malignant neoplasms or autoimmune disorders. We report the case of a 30-year-old man who presented with a 2-year history of scleredema. Further investigation led to the diagnosis of primary Sjögren’s syndrome. The association between scleredema and autoimmune disorders has been rarely seen. To our knowledge, there are no other reports describing the association between primary Sjögren’s syndrome and scleredema adultorum of Buschke.

Widespread Scleredema Accompanied with a Monoclonal Gammopathy in a Patient with Advanced Ankylosing Spondylitis

Scleredema is a rare cutaneous mucinosis characterized by chronic diffuse induration of the skin, and it is occasionally associated with a monoclonal gammopathy (MG). Ankylosing spondylitis (AS) is noted to be another, chronic systemic inflammatory disorder of the axial skeleton that may accompany the MG. However, patients with scleredema and AS accompanied with a MG have not been reported in the literature. We here report a 40-yr-old man with scleredema and advanced AS accompanied with a MG of IgA-kappa protein. Widespread, long-standing scleredema has been developed over 10 yrs after the initial manifestation of AS. It is uncertain whether the coexistence of scleredema and AS is more than coincidental.

Scleredema in a Child

A rare case of scleredema in a seven year old child is presented. This relevant literature regarding clinical presentation, differential diagnosis and treatment of this disease is also being reviewed.
