Railway track-like dermatitis: an atypical Mondor's disease?

The cases of two patients with linear, cordlike lesions on the anterolateral chest wall are reported. Both cases suggested a clinical diagnosis of Mondor's disease (i.e., sclerosing periphlebitis of the chest wall) with atypical aspects. The histologic picture showed a diffuse dermal infiltrate, predominantly of eosinophils mixed with lymphocytes and histiocytes, with some evidence of collagen degeneration. No flame figures were seen. Problems of differential diagnosis are discussed.
