Giant pseudomalignant granuloma.
A patient who developed rapidly growing, multicentric, cutaneous tumors clinically resembling pyogenic granuloma is reported. In spite of the fact that the local lesions expanded rapidly and contained cytologically "malignant" cells which appeared to invade dermal vessels, the patient had a benign clinical course. The differential diagnosis of "giant pseudomalignant granuloma" is discussed.
