REVIEW ARTICLE 305 Treatment of Scleroedema Adultorum Buschke: A Systematic Review Diana MIGUEL, Sibylle SCHLIEMANN and Peter ELSNER Department of Dermatology, University Hospital, Jena, Germany Scleroedema adultorum Buschke is a rare skin disease, which can be divided into 3 subtypes: classic type, oc- curring after respiratory infections; a type lacking as- sociation with infections; and a type associated with diabetes. Scleroedema adultorum Buschke is charac- terized by thickening and tightening of the skin, which typically starts at the neck. In half of patients, spon- taneous remission may occur. The aim of this syste- matic review is to summarize all reported treatments for scleroedema adultorum Buschke, based on articles from PubMed database, using the query “scleroedema adultorum Buschke treatment”, English and German, published between 1970 and 2016 and documenting adequate treatments. The results are based mainly on individual case reports, small case series, and retro- spective studies often reporting unsuccessful results. Treatment options include topical as well as systemic treatments, and physical modalities. There is a need for randomized controlled trials and studies on long- term outcomes after treatment. Key words: scleroedema adultorum Buschke; treatment. Accepted Nov 13, 2017; Epub ahead of print Nov 14, 2017 Acta Derm Venereol 2018; 98: 305–309.

E-mail: Diana.Miguel@med. uni-jena.de S cleroedema adultorum Buschke (SAB) is a rare skin condition of unknown aetiology that was first descri- bed by Curzio in 1752. However, its name is associated with Abraham Buschke who reported a 46-year-old patient developing skin hardening after an episode of influenza in 1902. The nomenclature has been criticized, since the disease also occurs in younger individuals lacking sclerosis. In fact, in 209 patients with SAB, 51% were younger than 20 years old. For childhood cases, SAB must be differentiated from scleroedema neonatorum (1–4). SAB is characterized by skin thickening and tighte- ning that typically starts at the neck and spreads over the upper part of the body, e.g. the face, scalp, shoulder, and trunk (Fig. 1). The hands and feet are usually not affected (5, 6). A case of SAB confined to the thighs has also been reported (7). SAB can be divided into 3 types: • type 1, or “classic type”, occurs in patients who have recently had a bacterial or viral febrile infection, usually of the upper respiratory tract. This type tends to resolve spontaneously within a few weeks up to 2 years. • type 2 refers to patients without an underlying infection as trigger factor, with a slow progressive course, and a tendency to chronicity. This type is also associated with paraproteinaemias with onset at a younger age. • type 3, also named “diabetic scleroedema”, is asso- ciated with diabetes mellitus, has a slow progressive course and, unlike types 1 and 2, occurs more often in men (8, 9). It is suggested that an irreversible gly- cosylation of collagen and alterations in collagenase activity lead to an accumulation of collagen and mucin in the dermis (10). There are no specific laboratory abnormalities, but the diagnostic workup of SAB should include analysis of anti-streptolysin O titre, haemoglobin A1c, sedimenta- tion rate, blood count, and protein electrophoresis. There is no racial or ethnic propensity, but women are usually more affected with type 1 and type 2 SAB than are men (1). Scleroedema has also been associated with internal malignancies, e.g. insulinoma and carcinoma of the gall bladder (11, 12). Histologically, SAB is characterized by a normal epidermis with an up to 4 times thickened dermis con- taining mucopolysaccharides, as evidenced by Alcian blue stain, in oedematous spaces between collagen fibres. The subcutaneous fat tissue is usually replaced by coarse collagen fibres (13). The course of scleroderma is usually slow and rarely fatal. Patient’s complaints include tightness, thickening, Fig. 1.
