title: Mycobacterial subcutaneous arteritis.
abstract: The authors report three patients with subcutaneous erythematous nodules in different phases of development, unspecific systemic symptoms, positive PPD test, and normal chest X-rays. The histopathological study of the older nodules showed a granulomatous arteritis with a few acid-fast bacilli in the vascular wall. The nodules at an early phase showed an unspecific panniculitis with some acid-fast bacilli in apparently normal cutaneous vessels. These findings suggest that the mycobacterium has a vascular tropism and may cause a primary granulomatous arteritis.
