A 53-year-old male presented with progressive asymptomatic cutaneous hardening on the nape of his neck for 6 months. The lesion had an insidious onset and caused the patient to experience impaired movement of the neck. Physical examination disclosed a symmetric woody-hard, nonpitting indurated erythematous plaque on the nape of his neck [Figure 1]a. A skin biopsy from the nape showed thickened reticular dermis with dermal fenestration [Figure 2]a and [Figure 2]b. Abundant mucin deposition in the deep dermis was demonstrated by Alcian blue stain [Figure 2]c. Scleredema adultorum of Buschke was therefore diagnosed. Laboratory data revealed anemia (9.7 g/dl) and hypercalcemia (10.2 mg/d). His renal function (creatinine: 1.09 mg/dL; range: 0.64–1.27), glycated hemoglobin (6.0%; range: 5.7–6.4), complement 3 (90 mg/dL; range: 90–180), and complement 4 (39 mg/dL; range: 10–40) were within the normal limits. Both anti-nuclear antibody and anti-streptolysin were negative. Serum protein electrophoresis showed a monoclonal band in the γ region and immunofixation confirmed a monoclonal immunoglobulin A and κ light chain. Radiographic skeletal survey showed diffuse osteopenia. In particular, multiple radiolucent lesions were seen at the skull and eighth thoracic spine. A bone marrow biopsy [Figure 2]d and [Figure 2]e showed increased plasma cells (80%) and staining of κ light chain proteins. A diagnosis of scleredema adultorum of Buschke in association with multiple myeloma of IgA-κ was made. The patient was started on VTD regimen (Bortezomib [Velcade] 1–1.3 mg/m2 subcutaneous on days 1, 4, 7, and 11; Thalidomide 100 mg perorally daily; Dexamethasone 40 mg perorally daily, four cycles). Subsequently, he received autologous peripheral blood stem cell transplantation after a preconditioning of high-dose melphalan. The treatment resulted in the rapid decline of monoclonal IgA with complete disappearance of paraprotein. The skin induration gradually improved, and he regained full neck mobility after 9 months of therapy [Figure 1]b. The patient remained disease-free at 24-month follow-up.

Scleredema adultorum of Buschke is a rare connective tissue disorder, characterized by symmetrical firm, woody nonpitting induration of the skin that typically affects the neck and gradually expands to the face, shoulders, and trunk. The hands and feet are usually spared. The differential diagnosis includes scleromyxedema and morphea (localized scleroderma). Histologically, both scleredema and scleromyxedma demonstrate mucin deposition, while morphea showed only fibrosis without mucin deposition. Scleromyxedema is characterized by waxy firm papules on induration, with fibrotic change on pathology examination, which differentiates from scleredema. Scleredema was classified into three groups based on associated comorbidities and different prognosis. Group I accounts for 55% of scleredema and is the classical type following a febrile illness (most commonly streptococcal infection of respiratory tract). It usually resolves spontaneously within months to 2 years. Group II accounts for 25% of scleredema and is associated with paraproteinemia (e.g., monoclonal gammopathy of undeterminated significance and multiple myeloma). These patients are typically younger and experience a protracted course compared with those without gammopathy., Group III constitutes around 20% of scleredema and is related to poorly controlled type II diabetes mellitus (scleredema diabeticorum). Scleredema associated with diabetes or monoclonal gammopathy has a slowly progressive and unremitting course. Although the mechanism is still poorly understood, Ohta et al. have shown that the serum isolated from affected patient stimulates collagen production in normal skin fibroblast cultures. Therefore, serum factors produced by myeloma cells might stimulate the production of mucinosis and dermal thickening.
In the literature review, only 17 cases of multiple myeloma-associated scleredema have been described. The male-to-female ratio was 1.2:1, and the mean age of onset was 60.1 ± 13.6 years. IgG-κ was the most common (45%), followed by IgA-κ (36%), IgG-λ (9%), and IgA-λ (9%)., Our patient is in his early fifties and his skin lesion leads to the early diagnosis of underlying multiple myeloma of IgA-κ.
Various treatments have been attempted in scleredema patients with limited success including ultraviolet A1 phototherapy or bath-psoralen plus ultraviolet A phototherapy, local radiotherapy, antibiotics, pituitary extract, and immunosuppressive agents (systemic and intralesional corticosteroid, methotrextate, azathioprine, cyclosporine, and cyclophosphamide). In patients with multiple myeloma-associated scleredema, treatment directed to the underlying myeloma usually results in profound improvement of associated scleredema., To date, several chemotherapy regimens have been used including melphalan, cyclophosphamide, vincristine, thalidomide plus steroids, and bortezomib or CVD regimen (cyclophosphamide, bortezomib [Velcade], and dexamethasone) followed by autologous transplantation., Of note, our case is the first case successfully treated with VTD regimen (bortezomib [Velcade], thalidomide, and dexamethasone) followed by autologous peripheral blood stem cell transplantation. Physicians should be familiar with the presentation of scleredema and its associated systemic involvement as timely diagnosis is important for the early treatment of underlying malignancy.
