Sarcoidosis is a multisystem disorder with cutaneous involvement with myriad of morphological presentations, often leading to diagnostic dilemma. We report a case of 31-year-old male with peripheral arterial disease who presented with three morphological forms of sarcoidosis simultaneously, namely, papular, psoriasiform, and pigmented purpuric dermatosis-like lesions. Dermatoscopy of cutaneous lesions showed yellow-orange globules, red dots, linear vessels, and white crystalline structures depending on the clinical forms. Histopathology of all three morphological types of skin lesions demonstrated sarcoidal naked granulomas.Sarcoid specific lesions of more than one morphological type presenting in a same patient is rare. Association of peripheral vascular disease with sarcoidosis is also seen rarely.
