Although well-developed erythema nodosum is classified as a lymphocytic or granulomatous septal panniculitis, this discussion focuses on early cases in which the histopathologic features are more variable and often consist of a neutrophilic component.
(2) suggested that septal panniculitis should be described as a histological type of sclerodermatous GVHD, and they found septal panniculitis in 6 (50%) of the 12 patients with biopsy specimens available for evaluation.
The simultaneous occurrence of Sweet's syndrome and erythema nodosum, a hypersensitivity septal panniculitis, is also well documented and the possibility of immune complex formation as a common initiating factor in both disorders has been suggested.
The presence of a granulomatous septal panniculitis, with perivascular and perineural lymphohistiocytic infiltrate and fragmented AFB in affected skin, was in accordance with the diagnosis of ENL.
