PY - 2019 T2 - Fitzpatrick's Dermatology, 9e AB - Inflammation in subcutaneous fat (panniculitis) often poses a diagnostic problem as the clinical and histopathologic findings in the various inflammatory disorders of adipose tissue (AT) have overlapping features (Table 73-1). A useful histopathologic classification divides the panniculitides into “septal” and “lobular” (Table 73-2), although several diagnoses exhibit overlapping features.1 This classification is expanded by noting the presence or absence of vasculitis,2 and the composition of the inflammatory infiltrate (Table 73-1).
