Review
Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) which preferentially infiltrates into subcutaneous adipose tissue is rare, however may mimic autoimmune diseases from the aspect of clinical manifestations. Here, we describe a 16-year-old young man, who initially presented with eyelid erythema and swelling, accompanied by fever and muscle and bone marrow involvement. He was preliminarily considered as a patient with classical dermatomyositis (DM), but finally diagnosed as SPTCL concomitant with paraneoplastic inflammatory myositis, confirmed by in total 8 times repeated biopsies at different sites. After systematically reviewing the literatures, we summarized the main features of SPTCL mimicking DM with eyelid edema as the presenting manifestation. The cautionary tale reminds rheumatologists of considering mimickers in patients with atypical autoimmune-like manifestations. Suitable biopsy is critical for diagnosis and improving prognosis.

Myelodysplastic syndrome (MDS) may present with specific skin lesions, such as leukaemia cutis, which is a well known poor prognostic marker of leukaemia with a high risk of acute leukaemic transformation. However, less is known regarding non-specific cutaneous manifestations of MDS including the prevalence, types and their prognostic and therapeutic significance, which we aimed to determine through this systematic review. We searched electronic databases (PubMed, Medline and EMBASE) from inception up to 26 January 2023 for studies reporting cutaneous manifestations of MDS. Eighty eight articles (case reports = 67, case series = 21), consisting of 134 patients were identified. We identified 6 common cutaneous manifestations: neutrophilic dermatoses ( = 64), vasculitis ( = 21), granulomatous ( = 8), connective tissue disease (CTD) ( = 7; composed of dermatomyositis ( = 5), cutaneous lupus erythematosus ( = 1), and systemic sclerosis ( = 1)), panniculitis ( = 4), immunobullous ( = 1), and other ( = 29). Cutaneous features either occurred at time of MDS diagnosis in 25.3%, preceding the diagnosis in 34.7% (range 0.5-216 months), or after diagnosis in 40.0% (range 1-132 months). Prognosis was poor (40.2% death) with 34.1% progressing to acute myeloid leukaemia (AML). 50% of those with MDS who progressed to AML had neutrophilic dermatoses ( = 0.21). Myelodysplastic syndrome was fatal in 39.2% of neutrophilic dermatoses (median time from onset of cutaneous manifestation: 12 months), 50% of vasculitis (7.5 months), 62.5% of granulomatous (15.5 months) and 14.3% of CTD (7 months). Recognition of patterns of cutaneous features in MDS will improve early diagnosis and risk stratification according to subtype and associated prognosis.

Review
MonoMAC syndrome is characterized by monocytopenia with susceptibility to nontuberculous mycobacterial infections. First recognized in 2011, it is caused by GATA2 mutations and can manifest as disseminated mycobacterial, fungal, and viral infections. While mortality rates for this disorder have been high, it has recently been successfully treated with haploidentical allogeneic stem cell transplant. Since approximately one third of patients may have rheumatologic symptoms, such as erythema nodosum, panniculitis, or arthralgias, rheumatologists may expect to encounter this newly described entity with increasing frequency.

Review
BACKGROUND
Subcutaneous fat necrosis of the newborn (SCFN) is a rare form of panniculitis manifesting as erythematous plaques or nodules at sites of brown fat in neonates. Surgical management may be indicated in severe cases; however, there is a paucity of literature compiling presentations and outcomes of these surgical patients.
METHODS
The authors performed a systematic review, in consultation with a licensed librarian, on MEDLINE and Embase for studies including patients with SCFN who were surgically managed.
RESULTS
The search strategy generated 705 results, among which 213 (30.2%) were excluded for lack of discussion on surgical management. Twenty-two studies discussed surgical management of SCFN in 26 patients, but in 6 of these studies the patients were not surgically managed. Ultimately, 16 articles with 16 patients who were surgically managed were included in the study. Average age at diagnosis was 11.8 ± 9.8 days; average age at surgery was 39.5 ± 70.4 days. The most common etiologies were "unknown" (6, 37.5%), therapeutic hypothermia (4, 25.0%), and birth complications (4, 25.0%). Patients harbored nodules on the back (14, 87.5%), upper extremities (7, 43.8%), lower extremities (7, 43.8%), buttocks (5, 31.3%), and head or neck (3, 18.8%). Linear regression models revealed the presence of back lesions and predicted concomitant medical complications (β = 2.71, p = 0.021).
CONCLUSIONS
Patients undergoing surgical management for SCFN most commonly harbor lesions on the back and extremities that are secondary to therapeutic hypothermia or of unknown origin. Reporting of additional cases is needed to further elucidate surgical management and outcomes.
