Granuloma sarcomatodes, also known as granuloma faciale and granuloma telangiectaticum, is a rare benign skin disorder characterized by the presence of firm, red or purple papules or nodules on the face. It is a type of granulomatous inflammation that primarily affects the dermis, although the exact cause of the condition is unknown.
The term "granuloma" refers to a small mass or nodule that forms in response to injury or inflammation. In the case of granuloma sarcomatodes, the granulomas are characterized by the presence of spindle-shaped cells, resembling those found in sarcoma, a malignant tumor of connective tissue. However, it is important to note that granuloma sarcomatodes is a benign condition, not a true sarcoma.
Clinically, granuloma sarcomatodes typically presents as solitary or multiple reddish-brown or violaceous papules or nodules that are usually painless. These lesions may be slightly raised, and in some cases, may develop a telangiectatic appearance due to the presence of dilated blood vessels. The condition primarily affects middle-aged to elderly individuals, with a slight predilection for males.
Diagnosis of granuloma sarcomatodes is usually made based on clinical appearance and confirmed by histopathological examination. A skin biopsy is performed to obtain a sample of the affected tissue, which is then analyzed under a microscope. The characteristic findings include a dense inflammatory infiltrate in the dermis, consisting of lymphocytes, histiocytes, and multinucleated giant cells.
Treatment options for granuloma sarcomatodes include topical or intralesional corticosteroids, cryotherapy, laser therapy, or surgical excision
