An atypical case of papular necrobiosis lipoidica masquerading as sarcoidosis

Sarcoidosis with necrobiosis‐lipoidica–like skin lesions: A challenge for the dermatologist

“…The coexistence of cutaneous sarcoidosis and NL is rare 8 . Lee et al 9 described seven cases of patients with sarcoidosis who developed skin lesions similar to NL, however, histologically diagnosed as sarcoidosis.…”

“…The coexistence of cutaneous sarcoidosis and NL is rare. 8 Lee et al 9 described seven cases of patients with sarcoidosis who developed skin lesions similar to NL, however, histologically diagnosed as sarcoidosis. The close relation of these two diseases reinforce the question of whether they fall on the same spectrum of granulomatous skin disease or possibly share a final common pathway.…”

Diffuse cicatricial alopecia and multiple telangiectatic indurated leg plaques

“…Atrophic sarcoidosis mimics NL clinically in presenting with well‐circumscribed depressed plaques in association with areas of hypopigmentation, telangiectasia, and possible ulceration 4–9 . Atrophic sarcoidosis has also been reported on the face and scalp as found in atypical lesions of NL 5,6,9–11 …”

“…The overlapping features between NL and sarcoidosis are further highlighted by the presence of some cases with skin lesions initially diagnosed as NL only to be found to have developed systemic sarcoidosis later, questioning the initial diagnosis 16 . Coexistence of NL and sarcoidosis 16–18 and NL that has clinically masqueraded as sarcoidosis including cases with papular sarcoidosis‐like presentation have been reported 10 …”

Papular spreading necrobiosis lipoidica: a rare clinical presentation of this pathology

“…In conclusion, we present a rare clinical form of papular NL, which is rarely described, with only one recent case report in the literature . This case illustrates the usefulness of dermoscopy and ultrasonography to support the final histopathological diagnosis in clinically atypical cases of NL.…”
