Diagnostic Considerations

See the list below:

  • Cold panniculitis neonatorum synonymous with adiponecrosis subcutanea

  • Sclerema neonatorum synonymous with sclerema adiposum neonatorum

  • Chilblain

  • Lupus erythematosus panniculitis [13]

Differential diagnosis also includes poststeroid panniculitis and frostbite. [14]

Cytophagic histiocytic panniculitis often presents with multiple subcutaneous nodules and eventuates in a bleeding diathesis. [15]

In endemic areas, cutaneous leishmaniasis may occasionally be part of the differential diagnosis. [16]

Equestrian perniosis is a rare disorder that appears as tender burning nodular plaques on bilateral thighs after riding in the cold; it tends to promptly resolve and has no known significant systemic disease associations. [17] It is histologically characterized by perivascular lymphocytic infiltrate that prominently involves the fat. Equestrian chilblain is also known as equestrian cold panniculitis. [18]

Familial chilblain lupus may be due to a novel mutation in the exonuclease III domain of 3' repair exonuclease 1 (TREX1). [19, 20]

Subcutaneous panniculitis‒like T-cell lymphoma is also in the differential diagnosis. [21, 22]
