Granuloma annulare is relatively uncommon problem in dermatopathology.
General
- Benign and self-limited condition.
- Etiology unknown - may be assoc. with trauma.[1]
- Associations: trauma, infections, diabetes mellitus, dyslipidemia, thyroid disease, malignancy, medications.[2]
- A deep GA can mimic a rheumatoid nodule; may be called a pseudorheumatoid nodule.[3]
Gross
- Typically extremities - usu. arms and hands.[1]
Image
Granuloma annulare. (WC)
Gross
- Antecubital fossae.[2]
Microscopic
Features:[4]
- Dermal palisading granuloma - typically superficial-to-mid dermis - surrounds:
- Necrotic collagen - key feature.
- Nuclei "missing" - have undergone karyolysis.
- Mucin - important.
- Loose/pale, paucicellular, eosinophilic.
- Necrotic collagen - key feature.
- Chronic inflammatory cells.
Notes:
- There may be multiple small foci with intervening normal dermis.[1]
- Granuloma annulare can be subclassified into subcutaneous and interstitial.
- Histomorphologically similar to Rheumatoid nodule.
- Neutrophils may be seen.[5]
DDx:
- Necrobiosis lipoidica - little mucin, no normal dermis between foci,[1] plasma cells - common,[6] may involve the fat - tend to be deeper.
- Rheumatoid nodule - has fibrin in the core of the granuloma (instead of mucin), multinucleated macrophages more common.[7]
- Epithelioid sarcoma - esp. if the lesion appears to be mid-to-deep dermis.
- Tattoo reaction (granuloma annulare-like) - case report.[8]

SKIN LESION, UPPER BACK, PUNCH BIOPSY: - SUPERFICIAL PALISADING GRANULOMAS WITH CORES OF NECROBIOTIC COLLAGEN, AND SCANT MUCIN; CONSISTENT WITH GRANULOMA ANNULARE.
Skin lesion, left elbow, excision: - Palisading granulomas with cores of necrobiotic collagen, and scant mucin consistent with granuloma annulare. COMMENT: An alcian-blue stain (pH 2.5) shows scant mucin. The granulomas are relatively deep; however, plasma cells are not apparent. The differential diagnosis is rheumatoid nodule.
Micro
The sections show hair bearing skin with superficial palisading granuloma with cores of necrobiotic collagen and mucin. Plasma cells are not apparent in association with the lesion.
The overlying epidermis matures normally to the surface and has no basal atypia.
