Clinically, the condition resembles cellulitis, that often causes a diagnostic problem. The report hightlights the importance of accurate diagnosis of panniculitis and its subtypes for its proper management. Clinical Presentation Two patients with clinically typical lesions of panniculitis on their lower extremities are described. The lesions in these 2 patients had marked clinical resemblance to cellulitis. However, with the help of biopsy and histopathological examination it was possible to accurately diagnose the distinct forms of panniculitis in these patients. It helped in the correct management of the patients with satisfactory outcome. It is concluded that in patients with lesions resembling cellulitis, especially on the shin, the possibility of panniculitis must be considered. The experience with these 2 patients highlights the need for accurate histological characterization as an essential step in the diagnosis and proper management of different forms of panniculitides
