Background: Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a malignant primary cutaneous T-cell lymphoma that shares significant clinical, histopathologic, and immunophenotypic overlap with lupus erythematosus panniculitis (LEP).

Methods: We performed immunohistochemistry for the MYC oncoprotein on 23 cases of SPTCL (one CD8 negative) and 12 cases of LEP to evaluate if there are quantitative or qualitative differences in protein expression of this marker in these entities.

Results: In SPTCL cases, the percentage of all cells that were c-Myc positive ranged from 0. Read More

Recognizing the significant biologic and clinical heterogeneity of mature T-cell and NK/T-cell lymphomas, the American Society for Blood and Marrow Transplantation invited experts to develop clinical practice recommendations related to the role of auto-HCT and allo-HCT for specific histologic subtypes. We used the GRADE methodology to assist in moving from evidence to decision-making and ultimately generating final recommendations. Auto-HCT in front-line consolidation is recommended in PTCL-NOS, AITL, ALCL-ALK negative, NK/T-cell (disseminated), EATL and hepatosplenic lymphomas. Read More

Background: Cutaneous manifestations are fairly common in rheumatoid arthritis (RA) and they can help in early diagnosis, prompt treatment, and hence reduced morbidity from the disease.

Aims: The objective of the present study was to find out the different patterns of dermatoses in a group of patients with RA from Eastern India.

Methodology: Consecutive patients fulfilling the American Rheumatism Association 1987 revised criteria for the classification of RA and who had different dermatoses were included in this cross-sectional study done over a period of 8 years in a tertiary care hospital in Eastern India. Read More

Erythema ab igne (EAI) represents the stereotype of a modern technology induced disease. Originally produced by repeated exposure of the skin to a heat source, more often because of habits related to the job or personal activities, this condition now tends to occur more frequently, being associated with a variety of modern instruments. The aim of our report is to discuss this strange medical condition with a focus on clinical features, possible confounding differential diagnoses and recommendations for prevention. Read More

Erythema nodosum (EN), is the most common variant of septal panniculitis and is possibly a delayed hypersensitivity reaction triggered by a wide range of antigenic stimuli. Hypersensitivity reactions due to medications have been recognized as a cause of 3-10% of EN cases. Case reports of EN associated with the anti-thyroid drugs are quite rarely reported in the literature even if there is a common use of anti-thyroid drugs. Read More

Scleroderma refers to an autoimmune connective tissue fibrosing disease, including three different subsets: localized scleroderma, limited cutaneous systemic sclerosis, and diffuse cutaneous systemic sclerosis with divergent patterns of organ involvement, autoantibody profiles, management, and prognostic implications. Although systemic sclerosis is considered the disease prototype that causes cutaneous sclerosis, there are many other conditions that can mimic and be confused with SSc. They can be classified into immune-mediated/inflammatory, immune-mediated/inflammatory with abnormal deposit (mucinoses), genetic, drug-induced and toxic, metabolic, panniculitis/vascular, and (para)neoplastic disorders according to clinico-pathological and pathogenetic correlations.

The alpha-1 antitrypsin (AAT) haplotype Pi*S, when inherited along with the Pi*Z haplotype to form a Pi*SZ genotype, can be associated with pulmonary emphysema in regular smokers, and less frequently with liver disease, panniculitis, and systemic vasculitis in a small percentage of people, but this connection is less well established. Since the detection of cases can allow the application of preventive measures in patients and relatives with this congenital disorder, the objective of this study was to update the prevalence of the SZ genotype to achieve accurate estimates of the number of Pi*SZ subjects worldwide, based on studies performed according to the following criteria: 1) samples representative of the general population, 2) AAT phenotyping characterized by adequate methods, and 3) selection of studies with reliable results assessed with a coefficient of variation calculated from the sample size and 95% confidence intervals. Studies fulfilling these criteria were used to develop tables and maps with an inverse distance-weighted (IDW) interpolation method, to provide numerical and geographical information of the Pi*SZ distribution worldwide.

Lupus mastitis is an uncommon manifestation of systemic lupus erythematosus (SLE) that affects the subcutaneous fat in the breast, much like lupus panniculitis, but additionally involves the mammary gland. We report on two women for whom lupus mastitis was the initial manifestation of SLE and provide a literature review of 34 additional cases reported in the Anglo-Saxon and French literature since 1971, making this the largest review to date. Lupus mastitis (LM) can manifest clinically as subcutaneous masses that may be painful, or may present cutaneous involvement such as thickening and discolouration. Read More

The combination of MEK inhibitor (cobimetinib, trametinib) and BRAF inhibitor (vemurafenib, dabrafenib) is now the first-line treatment in patients with BRAF V600-mutated metastatic melanoma. This association reduces cutaneous adverse events induced by BRAF inhibitors alone, including photosensitivity, hand-foot syndrome, hyperkeratosis, alopecia, skin papillomas, keratoacanthomas, and squamous-cell carcinomas. While panniculitis has exceptionally been reported with BRAF inhibitors, this rare side effect has never been described with the use of MEK inhibitors. Read More

Dermatologic manifestations are observed in almost all systemic vasculitides, even in large-and medium-vessel vasculitides, although such vessels are not found in the skin. Cutaneous manifestations may be related to a direct skin localization of the systemic vasculitis or a non-specific process associated with the vasculitis. According to the 2012 International Chapel Hill consensus, the two major variants of large-vessel vasculitides are Takayasu arteritis and giant-cell arteritis. Read More
