Purpuric papulonodular sarcoidosis mimicking granulomatous pigmented purpura

Pigmented purpuric dermatosis‐like sarcoidosis

“…The other case report of sarcoidosis with a purpuric component reminiscent of PPD was an 86-year-old man with diabetes mellitus type 2, characterized by purpuric papular lesions on the legs, and histopathologically by naked sarcoidal granulomas in the dermis in association with erythrocyte extravasation, which is in keeping with the clinicopathological features of our patient. 5 However, compared with our case, pulmonary involvement of sarcoidosis was identified in the reported patient with multiple small nodules in the upper and middle lungs, with a perilymphatic distribution. Treatment with prednisone 40 mg/day resulted in clearance of the lesions with a brownish discoloration within 1 month in that case.…”

“…[1][2][3][4] Recently, a purpuric variant of cutaneous sarcoidosis resembling pigmented purpuric dermatosis (PPD) has been documented. 5 Herein, we describe another unusual case with clinical features mimicking PPD and histopathological features consistent with sarcoidosis; we designated this unusual clinical presentation as "PPD-like sarcoidosis".…”

“…While papulonodular sarcoidosis is the main cutaneous manifestation of this entity, various atypical variants such as ichthyosiform, livedoid, erythrodermic, pseudotumoral, ulcerated and histiocytoma‐like sarcoidosis may cause confusion in diagnosis . Recently, a purpuric variant of cutaneous sarcoidosis resembling pigmented purpuric dermatosis (PPD) has been documented . Herein, we describe another unusual case with clinical features mimicking PPD and histopathological features consistent with sarcoidosis; we designated this unusual clinical presentation as “PPD‐like sarcoidosis”.…”

Granulomatous variant of pigmented purpuric dermatosis: report of two cases and review of the literature

“…In our patients, the histopathological fi ndings were more consistent with PPD, and supplementary clinical workup also favored this diagnosis. Case 2 shared some similarities with the recently described purpuric variant of cutaneous sarcoidosis [ 6,7 ] , with granulomas occurring not only in the papillary but also in the mid-reticular dermis. However, the patient reported by Bachmeyer [6] had a longstanding history of systemic sarcoidosis, and Sezer et al [ 7 ] favored the diagnosis of sarcoidosis based on the location of granulomas in the deep dermis.…”

Cutaneous Sarcoidosis

“…83,84 A photoinduced variant of sarcoidosis with seasonal variation in clinical disease also has been reported. 85 Special sites Scalp Sarcoidosis of the scalp can result in both scarring and nonscarring alopecia.…”
