Polymorphous Cutaneous Sarcoidosis With Excellent Response to Minocycline

Sarcoidosis is notorious for producing a wide variety of skin lesions, which are categorized as either specific or nonspecific. The specific lesions include primary morphologies ranging from micropapules to subcutaneous nodules. Nonspecific skin lesions include associated conditions like erythema nodosum, calcinosis cutis, and prurigo. It is not uncommon for a patient to have a combination of specific and nonspecific lesions. In contrast, it is exceedingly rare for one patient to have multiple specific sarcoidal lesions. When present, the term “polymorphous cutaneous sarcoidosis” has been used. We present the case of a patient who presented with three specific cutaneous morphologies of sarcoidosis: papular sarcoid, Darier-Roussy subcutaneous sarcoidosis, and lupus pernio. After only two months of oral minocycline, our patient demonstrated remarkable improvement with near-complete resolution of the cutaneous lesions. In addition to describing the rare polymorphous presentation, this case also highlights the challenge of relating lesion type to overall prognosis when multiple morphologies are present.
