AI Article Synopsis

  • The article discusses the diagnostic challenges of panniculitis for pathologists, organizing various inflammatory diseases of the subcutis.
  • It categorizes them based on their location (centered on fibrovascular septa or adipose lobules) and presence of morphologic vasculitis.
  • The review includes a range of conditions, highlighting significant examples and their histological features.

Article Abstract

The diagnosis of panniculitis is felt to be a confusing topic by some pathologists. 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. Septocentric, non-vasculitis disorders include erythema nodosum, panniculitis that follows the use of "biological" therapeutic agents, lipodermatosclerosis, post-irradiation panniculitis, morphea profunda, and necrobiosis lipodica profunda. Polyarteritis nodosa and Behçet's disease are the conditions that are based in the subcutaneous septa with vasculitis. Predominantly-lobular panniculitides with no vasculitis include pancreatogenic panniculitis, the panniculitis of alpha-1-antitrypsin deficiency, panniculitis associated with lupus erythematosus and dermatomyositis, subcutaneous Sweet syndrome, eosinophilic panniculitis, factitial panniculitis, cold panniculitis, panniculitis following injections of corticosteroids, lipomembranous (ischemic) panniculitis; sclerema neonatorum and subcutaneous fat necrosis of the newborn, and Rosai-Dorfman disease of the subcutis. Erythema induratum and infectious panniculitis are vasculitic and lobulocentric conditions. This article reviews the histological features of these diseases.

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare type of non-Hodgkin lymphoma characterized by subcutaneous nodules, indurated plaques, erythema, and cellular infiltrates in the subcutaneous fat. Biopsies show neoplastic cells expressing cytotoxic T-cell markers and displaying moderate cytologic atypia while sparing the dermis and epidermis and showing variable degrees of necrosis, hemorrhage, and inflammatory changes. We describe a pediatric case of SPTCL in a 6-year-old boy, presenting with an unusual targetoid plaque and systemic symptoms, who showed significant improvement on systemic immunosuppressants without chemotherapy.

The pancreatitis, panniculitis, polyarthritis (PPP) syndrome involves the association of pancreatic pathology, panniculitis of pancreatic origin, and polyarthritis secondary to intra-articular fat necrosis. The incidence is unknown, and the mortality rate is as high as 24%. Treatment targets the underlying pancreatic pathology.

A 9-month-old girl was evaluated for recurrent fevers, rash, and indurated plaques, with laboratories demonstrating hyperferritinemia, hypertriglyceridemia, and pancytopenia, concerning for hemophagocytic lymphohistiocytosis. Biopsy of thigh lesion ultimately demonstrated subcutaneous panniculitis-like T-cell lymphoma. In a rare neoplasm of cytotoxic T-cells, subcutaneous panniculitis-like T-cell lymphoma presents with subcutaneous nodules in all age groups including children.

Localized inflammatory reactions in patients with past procedural history of intradermal injections can quickly drive the clinician's attention towards a diagnosis of soft-tissue infection in the context of symptoms such as fever, malaise, and local induration of the adipose panniculus. However, in patients with a long-term history of granulomatous events, a rheumatologic approach must be taken into consideration when the clinical course overwhelms the odds for more conventional diagnoses. In this case, a 39-year-old female patient who underwent bilateral lower limbs intradermal filllers presented with a two-year clinical course of repetitive flares of external bilateral hip tenderness, pain that limits her walking, soft-tissue nodular inflammation, redness, fever and a soft mobile nonpainful right supraclavicular lymphadenopathy.
