You're likely to be describing a histiocytoma - a benign neoplasm of mononuclear cells derived from epidermal Langerhans' cells (sorry for the pedantry). It's common in dogs with highest incidence in young adults younger than 4 years of age. It usually manifests as a solitary, rapidly growing, firm, well-circumscribed, erythematous (reddened), raised, alopecic dermal nodule that ranges from 0.5 to 4 cm in diameter. Lesions may be ulcerated and occur most commonly on the head, ear pinnae, and legs. Observation without treatment is reasonable because most lesions regress spontaneously within 3 months. Surgical excision or cryotherapy is curative for lesions that don't regress spontaneously.
