UNLABELLED The second part of our review of panniculitis summarizes the clinicopathologic features of the mostly lobular panniculitides. Erythema induratum of Bazin (nodular vasculitis) represents the most common variant of lobular panniculitis with vasculitis, although controversy persists about the nature of the involved vessels. Mostly lobular panniculitides without vasculitis comprise a series of disparate disorders. These include sclerosing panniculitis that results from chronic venous…

This summarical article presents inflammatory diseases of the subcutis in a systematic fashion, based on whether they are centered on fibrovascular septa or the adipose lobules, and whether morphologic vasculitis is present or not.

Lupus panniculitis involving the parotid/periparotid regions and breast; a rare presentation.

A chronic case of lupus pannicultis in a middle-aged woman affecting her face including the left parotid/periparotid region, left upper arm and right breast is reported.

Elastofibromatous lesion as a differential diagnosis of white lesions of the oral mucosa

A case of panniculitis with fat necrosis and numerous eosinophils, which was associated with AFG is described, after considering other possibilities, hypersensitivity reaction to substances released by adipocytes duringfat necrosis or inflammatory cytokines may have been a culprit.

Lobular panniculitis: A manifestation of pancreatic tumor with fatal outcome

A 77-year-old woman was in apparently good general health condition when developed skin lesions in a form of erythematous painful fluctuant nodules localized predominantly on the breast, but also present on the arms, thighs, and trunk, which became progressively debilitated and she died before operation.

Factitious panniculitis masquerading as pyoderma gangrenosum

A case of factitious panniculitis masquerading as florid pyoderma gangrenosum in a 35‐year‐old woman, who had tender, ecchymotic plaques over the lower trunk and limbs, who was treated with a range of topical and systemic medications.

Clues in Histopathological Diagnosis of Panniculitis

12 clues in panniculitis dermatopathological diagnosis such as presence of granulation tissue, sclerotic connective tissue septa, small granulomas arranged around a central clear space, so-called ghost adipocytes, needle-shaped crystals, small lobules with a proliferation of capillaries, Splendore-Hoeppli phenomenon, refractile microspheres, neutrophilic infiltrates, granuloma and fibroplasia are reviewed.

Lymphocytic panniculitis: an algorithmic approach to lymphocytes in subcutaneous tissue

This review provides an algorithmic approach to the diagnosis of lymphocyte-predominant panniculitis, including entities of septal- Predominant pattern pannculitis (erythema nodosum, deep necrobiosis lipoidica, morphea profunda and sclerosing panniulitis) and lobular-Predominantpattern pannICulitis.

Postirradiation pseudosclerodermatous panniculitis: three new cases with additional histopathologic features supporting the radiotherapy etiology.

Dermal vessels showed sclerotic vessel walls and atypical bizarre fibroblasts with large pleomorphic and hyperchromatic nuclei were interstitially arranged between collagen bundles of the dermis, representing additional histopathologic features supporting the pathogenic role of the radiotherapy in the development of this rare variant of panniculitis.



The histopathologic spectrum of erythema induratum of Bazin.

The presence of primary vasculitis and granulomas suggests that types III and IV hypersensitivity reactions play a role in the pathogenesis or erythema induratum of Bazin.

Neutrophilic lobular (pustular) panniculitis associated with rheumatoid arthritis: a case report and review of the literature.

A 42-year-old woman with seropositive RA who presented with a 2-month history of lower leg panniculitis is reported, showing a lobular neutrophilic infiltrate with lipophages and central basophilic necrosis and focal changes of lipomembranous fat necrosis indicative of ischemic damage.

Eosinophilic panniculitis: a clinicopathologic study

Study of 18 patients with biopsy diagnoses of eosinophilic panniculitis revealed diverse paterns of systemic disease, including Wells' syndrome, vasculitis, atopy, and erythema nodosum as well as

It is concluded that lipomembranous fat necrosis is most likely a nonspecific form of ischemic fat degeneration that may be induced by various clinical entities and is proposed to be stasis-associated lipomEMbranusous panniculitis (SALP).

Eosinophilic panniculitis: diagnostic considerations and evaluation.


There is a group of diseases which involve primarily the legs, characterized by the presence of nodules and sometimes by ulceration and which are associated with varying degrees of involvement of the


Two cases of relapsing febrile nodular nonsuppurative panniculitis were observed at the Massachusetts General Hospital in 1937, and because the number of known cases is so small, it was thought
