Abstract
Multisystem inflammatory syndrome in children (MIS-C) is a rare and serious complication of Sars-Cov-2 infection. Dermatologic manifestations are present in the majority of patients. Skin lesions found in children with MIS-C are classified into four categories: morbilliform, reticulated, scarlatiniform, and urticarial lesions. Clinicopathologic characterization within these categories is limited. Thus, we present a clear example of an urticarial lesion in the context of MIS-C with well-documented clinicopathologic phenomena. A previously healthy 16-year-old female presented with 3 weeks of an itchy, burning rash initially presenting on her right forearm (and lasting greater than 24 hours without migration) before spreading diffusely. She also reported fever, cough, myalgias, nausea, and vomiting of 4 weeks' duration. Physical examination revealed an edematous, maculopapular, nonblanching, erythematous rash covering the patient's upper extremities, abdomen, back, anterior thighs, and face. The patient tested positive for COVID-19. A low-grade leukocytoclastic vasculitis was noted along with intraluminal fibrin and rare microthrombi in vessels of the mid to deep dermis. The patient was diagnosed with MIS-C and urticarial vasculitis. She was treated with steroids and naproxen for subsequent MIS-C flares. Dapsone treatment was started for the urticarial vasculitis.

Noncanonical NF-κB Signaling Upregulation in Inflammatory Bowel Disease Patients is Associated With Loss of Response to Anti-TNF Agents. Front Pharmacol 2021; 12:655887.

Abstract
Objectives: Targeting tumor necrosis factor (TNF) with biologic agents, such as infliximab and adalimumab, is a widely used and effective therapeutic strategy in inflammatory bowel disease (IBD). Unfortunately, a significant number of patients fail to respond or lose response over time to these agents. Previous studies have defined multiple complex roles for canonical NF-κB signaling in the pathogenesis of IBD. However, preliminary evidence suggests that the lesser defined noncanonical NF-κB signaling pathway also contributes to disease pathogenesis and response to anti-TNF agents. The objective of this study was to evaluate this hypothesis in Crohn’s disease (CD) and ulcerative colitis (UC) patients. Design: A total of 27 subjects with IBD (19 with CD and 8 with UC) and 15 control subjects were tested. Clinical criteria, patient history, and endoscopic disease activity were factors used to categorize patients and define therapeutic response. Biopsy specimens were collected during colonoscopy and expression was determined for 88 target genes known to be associated with noncanonical NF-κB signaling and IBD. Results: Noncanonical NF-κB signaling was significantly upregulated in IBD patients and was associated with increased gastrointestinal inflammation, epithelial cell death, lymphocyte migration, and Nod-like receptor signaling. Furthermore, noncanonical NF-κB signaling was further upregulated in patients unresponsive to anti-TNF agents and was suppressed in responsive patients. MAP3K14, NFKB2, CCL19, CXCL12, and CXCL13 were significantly dysregulated, as were genes that encode pathway regulators, such as CYLD, NLRP12, and BIRC2/3. Conclusion: Our study identifies a previously uncharacterized role for the understudied noncanonical NF-κB signaling pathway in the pathogenesis of IBD and anti-TNF therapy responsiveness. The genes and pathways identified may ultimately prove useful in IBD management and could potentially be used as biomarkers of drug response.

Abstract
Erythema ab igne is an uncommon physical dermatosis that presents with localized patches of reticulated erythema and hyperpigmentation corresponding with the underlying dermal venous plexus. The rash occurs in response to chronic heat exposure that does not meet the threshold for thermal burn of the skin. The histopathologic findings are characterized by atrophy and thinning of the epidermis, focal hyperkeratosis, and keratinocyte atypia. The dermis displays dilated capillaries, evidence of pigment incontinence, and prominent elastotic material. We report a case of a 65-year-old male who presented to his primary care physician with a 1-year history of reticular erythema and hyperpigmentation with focal ulceration on his right lateral leg. Histopathology on biopsy revealed mild hyperkeratosis and focal epidermal atrophy; however, the most striking finding was a proliferation of dermal vascular spaces lined by pleomorphic endothelial cells and numerous mitotic figures, which was morphologically compatible with angiosarcoma. However, clinicopathologic correlation and immunostaining revealed an actual diagnosis of erythema ab igne with reactive angiomatosis. Reactive angiomatosis-morphologically mimicking angiosarcoma-is a rarely reported feature of severe erythema ab igne, and dermatopathologists should be aware of this possibility to avoid misdiagnosis of erythema ab igne as angiosarcoma.

Abstract
ABSTRACT Leiomyosarcoma is a common sarcoma of both organs and soft tissues; however, large intradermal tumors are extremely rare. Presented is a pleomorphic leiomyosarcoma in a 64-year-old man, initially considered to be a ruptured epidermal inclusion cyst. The patient had a mildly tender, enlarging soft-tissue mass with a central pore on his right upper back. Incomplete extirpation showed a 5 × 5 cm heterogeneous, predominantly pleomorphic sarcoma with areas of fascicular and storiform spindled cells infiltrating the subcutaneous soft tissue to the underlying fascia and extending upward into the middle and upper dermis with prominent extension into pilosebaceous units. There were small foci with myxoid stroma and large areas of necrosis. CD31 demonstrated thin-walled curvilinear vessels throughout the tumor. The first desmin immunohistochemical stain near areas with myxoid stroma was negative but smooth muscle actin positive. However, desmin positivity was strong and diffuse in the spindled and more pleomorphic areas on 2 additional tissue sections. No rhabdomyoblasts or striated muscle fibers were seen. A diagnosis of pleomorphic leiomyosarcoma was rendered. This case highlights a unique clinical and histological presentation of a leiomyosarcoma initially mistaken to be a ruptured epidermal inclusion cyst, and the need to sometimes apply ancillary immunohistochemical studies to sections from more than one tissue block to accurately differentiate heterogeneous sarcomas with similar histologic features.

Abstract
CASE A 14-year-old female presented with a profound foot drop after trauma to the right leg. Clinical examination and electrodiagnostic studies demonstrated a dense palsy of the common peroneal nerve. Magnetic resonance imaging revealed an intraneural peroneal ganglion cyst at the fibular neck. Surgical treatment included decompression and transection of the articular branch to the proximal tibiofibular joint. At the 1-year follow-up, the patient demonstrated complete recovery of peroneal nerve function. CONCLUSIONS This case demonstrates a rare finding of a pediatric intraneural peroneal ganglion cyst. The presentation and treatment is well-documented and adds depth to the literature on a sparsely reported condition.

Abstract
McArdle disease is a rare autosomal recessive disorder of muscle glycogen metabolism that presents with pain and fatigue during exercise. Stiff-Person Syndrome is an autoimmune-related neurologic process characterized by fluctuating muscle rigidity and spasm. Reported is a 41-year-old male who presented to the emergency department due to sudden-onset weakness and chest pain while moving his refrigerator at home. Cardiac workup was non-contributory, but a creatine kinase level > 6,000 warranted a muscle biopsy. The biopsy pathology report was misinterpreted to be diagnostic for McArdle disease given the clinical presentation. After 4 years of treatment without symptomatic improvement, a gradual transition of symptoms from pain alone to pain with stiffness was noted. A positive glutamic acid decarboxylase antibody test resulted in a change of diagnosis to Stiff-Person Syndrome. This is the first known case that highlights the similarities between these two rare and distinct disease processes, highlighting the necessity for thorough history taking, maintenance of a broad differential diagnosis, and knowledge of how best to interpret complex pathology reports.

Abstract
Hidradenitis suppurativa is a poorly understood, destructive disease centered on pilosebaceous units and characterized by inflammatory nodules that progress to abscesses, sinus tracts, and scars. The typical patient is a young woman with involvement of the axillae, breasts, and groin. Presented is a 60-year-old man with poorly controlled diabetes, who initially developed pink-to-yellowish plaques with punched out ulcers on his knees that evolved to scars and draining sinus tracts. Draining sinus tracts were also noted under the left axilla. Histopathology revealed suppurative granulomatous inflammation centered on hair follicles as well as sinus tracts. Special stains for fungus and mycobacterial bacilli were negative. Cultures and PCR for mycobacterial tuberculosis were negative. The patient was diagnosed with hidradenitis suppurativa. A treatment trial of topical corticosteroids and antibiotics was given, but this regimen failed to improve his lesions. The patient was then started on adalimumab, which yielded marked improvement within three months. This case is reported because of the unusual clinical presentation and to highlight the spectrum of atypical hidradenitis suppurativa.

Abstract
New methods of tumor ablation have shown exciting efficacy in pre-clinical models but often demonstrate limited success in the clinic. Due to a lack of quality or quantity in primary malignant tissue specimens, therapeutic development and optimization studies are typically conducted on healthy tissue or cell-line derived rodent tumors that don't allow for high resolution modeling of mechanical, chemical, and biological properties. These surrogates do not accurately recapitulate many critical components of the tumor microenvironment that can impact in situ treatment success. Here, we propose utilizing patient-derived xenograft (PDX) models to propagate clinically relevant tumor specimens for the optimization and development of novel tumor ablation modalities. Specimens from three individual pancreatic ductal adenocarcinoma (PDAC) patients were utilized to generate PDX models. This process generated 15-18 tumors that were allowed to expand to 1.5 cm in diameter over the course of 50-70 days. The PDX tumors were morphologically and pathologically identical to primary tumor tissue. Likewise, the PDX tumors were also found to be physiologically superior to other in vitro and ex vivo models based on immortalized cell lines. We utilized the PDX tumors to refine and optimize irreversible electroporation (IRE) treatment parameters. IRE, a novel, non-thermal tumor ablation modality, is being evaluated in a diverse range of cancer clinical trials including pancreatic cancer. The PDX tumors were compared against either Pan02 mouse derived tumors or resected tissue from human PDAC patients. The PDX tumors demonstrated similar changes in electrical conductivity and Joule heating following IRE treatment. Computational modeling revealed a high similarity in the predicted ablation size of the PDX tumors that closely correlate with the data generated with the primary human pancreatic tumor tissue. Gene expression analysis revealed that IRE treatment resulted in an increase in biological pathway signaling associated with interferon gamma signaling, necrosis and mitochondria dysfunction, suggesting potential co-therapy targets. Together, these findings highlight the utility of the PDX system in tumor ablation modeling for IRE and increasing clinical application efficacy. It is also feasible that the use of PDX models will significantly benefit other ablation modality testing beyond IRE.

Abstract
Metastasis from salivary gland tumors to liver is exceedingly uncommon. Reported is the first case of a mammary analog secretory carcinoma (MASC) of salivary gland origin metastasized to the liver, even after complete surgical resection. A 76 year old female, with past history of a completely extirpated right parotid gland MASC, presented 2 years after right superficial parotidectomy and right neck dissection, with back and flank pain. Subsequent abdominal and pelvic CT revealed multiple small hepatic lesions. Biopsy of the largest hepatic lesion confirmed metastatic MASC of primary parotid gland origin. Both the parotid primary and the hepatic metastases had the confirmatory ETV6 rearrangement by fluorescence in situ hybridization. Although high-grade malignancy and distant metastases of MASC of salivary gland origin to liver is rare, recognizing metastatic MASC potentially alters prognosis and determines therapeutic options.

Abstract
Cutaneous endometriosis is an uncommon dermatologic disorder predominantly seen in young women. Most commonly, it presents within a region of a previous surgical scar, often in relation to a gynecologic procedure on the abdomen or in close proximity to the umbilicus. The typical clinical presentation is that of papules or nodules with monthly cyclical pain and size variation. Histologically, the lesions are composed of endometrial stroma and glands. The pathophysiology is not well understood but is believed to be due to metastasis or seeding of endometrial cells. When this uncommon disorder occurs outside of the most typical clinical setting, it may cause some diagnostic difficulty. In this report, we present the first known case of cutaneous endometriosis on the eyelid.

Abstract
Introduction Metastasis to the gallbladder is not common and usually manifests an advanced stage of malignancy. Herein, we report a case of triple negative high grade invasive ductal carcinoma of breast with a metastatic lesion to the gallbladder. Case Presentation The patient is a 52-year-old female diagnosed with invasive ductal carcinoma treated with mastectomy and chemotherapy. After 12 months, she presented to the emergency department with right upper quadrant pain and elevated liver chemistries. Abdominal enhanced computed tomography showed periportal and gallbladder wall edema. After cholecystectomy, the resected gallbladder was histologically considered to be a metastatic lesion arising from the primary lung cancer. The second case describes a case of a 77-year-old woman with multiple co-morbidities who presented to the hospital with sepsis secondary to biliary source. Abdominal enhanced computed tomography findings were concerning for acute cholecystitis. After cholecystectomy, the pathology of the resected gallbladder demonstrated cholecystitis and plasmacytoma. Conclusion The atypical presentation of gallbladder metastases could mislead treating providers. The diagnosis might alter management decisions and prognosis.

Abstract
Hyalinizing clear cell carcinomas (HCCC), now referred to as clear cell carcinomas (CCC) by the World Health Organization (WHO), are rare tumors usually arising from the salivary glands of the head and neck. We present the first case of a CCC originating from the trachea. A 66 year-old woman with history of hypertension, former smoker, presented to the emergency department reporting worsening shortness of breath. Computed chest tomography revealed a polypoid mass arising from the left posterior-lateral wall of the trachea. The patient developed worsening respiratory failure requiring mechanical ventilation. Bronchoscopy was completed which relieved a malignant airway obstruction and pathology revealed nests of cells with monomorphic nuclei and clear cytoplasm set in a hyalinized stroma. Using break apart probe fluorescence in situ hybridization testing the tissue revealed the presence of a recurring translocation of the Ewing sarcoma (EWSR1) gene, confirming the diagnosis. CCC is a rare primary airway tumor. CCC was first reported to originate in the lung in 2015. We present the first case of CCC arising from the trachea.
