Granuloma annulare represents a reaction pattern that is recognized as idiopathic in many cases but is attributed to a variety of inciting factors in some cases. In this report, we present a case of granuloma annulare-like pattern reaction to tattoo pigment.

Perforating granuloma annulare (PGA) is a rare subtype of GA. It is characterized by crops of erythematous umblicated or scaly papules. Plaques, pustule-like lesions and scars may also be seen. It can be localized or generalized.Transepithelial elimination of mucinous, degenerating collagen fibers and surrounding palisading lymphohistiocytic granulomas, are important hi...

A biopsy from the lesion on the hand was consistent with features of localized granuloma annulare. The patient was reassured that the condition was self-limited. The lesion on her calf, however, grew larger and new nummular and annular plaques developed that ultimately involved her legs, arms, abdomen, and back. A new diagnosis was made of generalized granuloma annulare. During the next 21⁄2 ye...

GA: granuloma annulare IGDR: interstitial granulomatous drug reaction INTRODUCTION Granulomatous drug eruptions are rare and include interstitial granulomatous drug reaction, drug-induced granuloma annulare, drug-induced accelerated rheumatoid nodulosis, and druginduced sarcoidosis. The differential diagnosis is broad and includes granuloma annulare, lichen planus, connective tissue disease, sa...
