For example, pathologists have a rather broad understanding of what they mean by granulomatous inflammation, ranging from compact sarcoidal
granulomas to diffuse polymorphic inflammation with macrophages, lymphocytes, and fibroblastic inflammation.
Less frequent reactions at injection sites include vascular thrombosis, mucinosis, dermal and SC sclerosis, necrosis, ulceration and rarely, lupus erythematosus-like lesions, sarcoidal granulomas, erythema nodosum, an acute septal panniculitis with neutrophils, lobular lymphocytic panniculitis and lipoatrophy.
Other described histological reactions at injection sites include allergic contact dermatitis, lipogranulomas, local necrosis, sterile and infectious abscesses, necrotizing, necrobiotic and sarcoidal granulomas, cutaneous lymphoid hyperplasia, lupus profundus-like and morphea-like reactions.
tissue reaction another complication of ear piercing.
involvement of the uterus may include both endometrium and myometrium, in contrast to the relative rarity of myometrial involvement by tuberculosis.
Cutaneous sarcoidal granulomas and the development of systemic sarcoidosis.
Hydroxychloroquine is effective therapy for control of cutaneous sarcoidal granulomas.
Although there is no pathognomonic finding to differentiate a sarcoidal granuloma from a granuloma of another cause, some features favor a granuloma being sarcoidal.
Giant cell arteritis can be differentiated from necrotizing sarcoidal angiitis by the lack of granulomatous inflammation in the myocardium outside of the coronary arteries, the lack of granulomatous inflammation in other organs outside of the arteries, and the demographics of the patient because giant cell arteritis is primarily a disease of elderly white women, unlike sarcoidosis.
Sarcoidosis was ruled out because eosinophilic abscesses were not features of sarcoidal
Noncaseating granulomas of sarcoidal
type can develop in the lung and hilar lymph nodes in association with bronchogenic carcinoma and presumably represent an immune response of the host to the carcinoma.
