title: Non-infectious granulomatous conditions of the skin: a clinicopathological approach to diagnosis.
abstract: Granulomatous disorders of the skin are diverse and include infectious and non-infectious conditions. They are a source of confusion to many dermatologists and pathologists, including even the most experienced dermatopathologists. Correlation with clinical picture, serology, microbiology and careful morphological examination is essential for accurate diagnosis. Most cases require ancillary histopathological studies to reach a final diagnosis. This review discusses important non-infectious granulomatous conditions of the skin and presents a practical approach when confronted with such entities.
