The association between mesenteric panniculitis and Sjögren's syndrome, although rare, is starting to be recognized. Usually, mesenteric panniculitis is symptomatic, presenting with either general or gastrointestinal symptoms. Sjögren's syndrome is an autoimmune disease that typically affects secretory glands, but may have serious systemic involvement. Read More

Alpha-1 antitrypsin deficiency (AATD) is a genetic disorder which most commonly manifests as pulmonary emphysema. Accordingly, alpha-1 antitrypsin (AAT) augmentation therapy aims to reduce the progression of emphysema, as achieved by life-long weekly slow-drip infusions of plasma-derived affinity-purified human AAT. However, not all AATD patients will receive this therapy, due to either lack of medical coverage or low patient compliance. Read More

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare condition that falls underneath the umbrella of primary cutaneous T-cell lymphomas (CTCLs). SPTCL can be very difficult to diagnose as it may mimic other subtypes of CTCL, such as γ/δ T-cell lymphoma (TCL), or other forms of panniculitis. Confirmation of diagnosis often requires immunohistochemical analysis and is essential for proper prognosis and therapeutic management. Read More

Purpose: The aim was to compare computed tomography (CT) findings between patients with mesenteric panniculitis (MP) with and without known malignancy.

Patients And Methods: We retrospectively analyzed 116 consecutive patients who were diagnosed with MP on the basis of CT findings and categorized them according to the absence (Group 1: 73 patients) or presence (Group 2: 43 patients) of malignancy. Patient age and sex, diameter, size, mass effect, location, and fat density of the MP mass, presence of a pseudocapsule and/or halo sign, and lymph node status were compared between the two groups.

There are a number of rare T-cell lymphoma subtypes that may be encountered in clinical practice. In recent years, improved immunohistochemical techniques and molecular tumor profiling have permitted refinement of some of the diagnostic categories in this group, as well as the recognition of distinct conditions not previously well elucidated. In this chapter, we cover the diagnostic and clinical features of some of the more common of these conditions, including subcutaneous panniculitis-like T-cell lymphoma, cutaneous gamma-delta T-cell lymphoma, enteropathy-associated T-cell lymphoma, monomorphic epitheliotropic intestinal T-cell lymphoma, primary cutaneous CD8-positive aggressive epidermotropic cytotoxic T-cell lymphoma, CD4-positive small/medium T-cell lymphoproliferative disorder, and acral CD8-positive T-cell lymphoma.

Subcutaneous panniculitis-like T-cell lymphoma (SPTL) is a rare form of cytotoxic T-cell lymphoma. It is believed that SPTL in patients without hemophagocytic syndrome (HPS) follows an indolent course; in contrast, SPTL in patients with HPS has been associated with unfavorable survival. To provide more clinical data on SPTL in Asian populations and to identify optimal therapeutic strategies for SPTL, we assessed the clinicopathological features and long-term follow-up data of 10 Taiwanese SPTL patients diagnosed at a single center.

Non-neoplastic skin lesions comprise a sizable group of disorders with variable etiologies and clinical manifestations. They can be grouped into vesiculopustular dermatitides; spongiotic and psoriasiform diseases; lichenoid dermatitides; lymphoid infiltrates of the dermis; granulomatous processes; bullous disorders; vasculopathies; panniculitides; deposition disorders; and defects in maintenance of dermal connective tissue. The use of histochemical methods continues to be an indispensable adjunct to conventional microscopy in the further characterization of such lesions. Read More

The spectrum of factors known to mediate autoinflammation has broadened recently to include not only interleukin-1 (IL-1) and interferon, but also abnormalities that impair NF-κB pathway negative regulation. The NF-κB pathway is activated upon contact of a ligand with tumor necrosis factor receptor 1 (TNFR1) and plays a pivotal role in triggering the inflammatory process by producing major cytokines such as IL-1, IL-6, and TNF. Negative regulation of the NF-κB pathway, which is essential to stop the inflammatory process, depends on the level of ubiquitination of the proteins associated with TNFR1 and of other intermediate compounds.

Rationale: Subcutaneous panniculitis-like T cell lymphoma (SPTCL) is a rare primary cutaneous T cell lymphomas expressing α/β T cell receptors that preferentially involves subcutis, and few reports have investigated the diagnosis of suspicious relapsed SPTCL using F-fluoro-2-deoxy-D-glucose (F-FDG) positron emission tomography/computed tomography (PET/CT).

Patient Concerns: A 15-year-old woman complaining of a growing painless subcutaneous mass on perinaeum recurred 2 months ago, suggestive of suspicious relapsed SPTCL, underwent FDG PET/CT for diagnosis and treatment follow-up.

Diagnosis: Based on the feature of FDG PET/CT images which revealed multiple increased FDG-avid subcutaneous adipose tissue lesions on the left upper arm, the left chest and perinaeum, involvement of bilateral inguinal lymph nodes, and the effective chemotherapy, she was diagnosed with relapsed SPTCL.

Neutrophilic panniculitis is an infrequent but characteristic adverse event under therapy with BRAF inhibitors (BRAFi). Since the approval of vemurafenib for treatment of metastatic melanoma in 2011, only two cases of neutrophilic panniculitis in malignancies other than melanoma have been published. Histiocytoid infiltrates of immature neutrophils resembling histiocytes or myelocytes have been reported in Sweet's syndrome and rarely in other neutrophilic dermatoses. Read More
