Atypical Intramuscular Lipoma of the Tongue. Case Report.

Although they are frequently benign tumors of mesenchymal origin, lipomas sporadically develop in the oral cavity. Intramuscular lipomas, which originate inside muscles, are a rare subtype. When found in the tongue, they are considerably more uncommon and its etiology remains unclear.

Autoimmune rheumatic diseases associated with granulomatous mastitis.

Granulomatous mastitis (GM) is a benign, inflammatory condition of the breast that mainly affects women of reproductive age. Although its pathogenesis remains unknown, previous studies revealed an association between autoimmune rheumatic diseases (ARDs) and GM in a subset of patients implicating immune-mediated mechanisms. The aim of this narrative review was to identify and describe the ARDs associated with GM to shed further light on disease pathogenesis.

Granulomatous mastitis, erythema nodosum and arthritis syndrome: case-based review.

Granulomatous mastitis (GM) is a rare form of inflammatory breast condition associated with unilateral or bilateral breast pain, swelling and mass formation. Although the disease pathogenesis remains unknown, several reports have associated GM with manifestations such as erythema nodosum and occasionally with arthritis, suggesting that GM might have an autoimmune disease component. We aim to describe two cases of coexistence of GM, erythema nodosum, and arthritis.
