Development Of Solitary Keratoacanthoma From A Cutaneous Wart, Joshua M. Ninan, Veronica Salazar
Development Of Solitary Keratoacanthoma From A Cutaneous Wart, Joshua M. Ninan, Veronica Salazar
Research Symposium
Background: Common cutaneous warts, referred to in medicine as verrucae vulgaris, are proliferative lesions caused by human papillomavirus. These lesions are mostly benign and usually resolve without incident, except in the case of the patient mentioned in this report. Our patient developed a solitary keratoacanthoma, currently accepted as a clinical variant of squamous cell carcinoma, as a result of several risk factors and traumatic exposure. The current literature does not have an established association of HPV with solitary keratoacanthomas. This case report explores the presentation and pathogenesis of solitary keratoacanthomas within the setting of HPV.

Case Of Rosai Dorfman Disease In A Patient With Newly Diagnosed Hodgkin Lymphoma, Liza Salloum, Jennifer Rojas Huen, Ricardo Serna, Alisha Valdez
Research Symposium
Background: Rosai Dorfman Disease (RDD, also known as sinus histiocytosis with massive lymphadenopathy) is a rare non-Langerhans cell histiocytosis, classified into nodal (classic) and extranodal disease. Most patients present with non-tender cervical lymphadenopathy, although other sites including the inguinal and axillary regions have been reported. Extranodal disease (~43% of cases) can involve any organ system. RDD is more common in children, but cases have been reported in patients in their 70s. The prognosis of nodal RDD can correlate with the number of nodal groups involved. Many cases can be managed only with observation, although surgery, chemotherapy, corticosteroids, and immunomodulators have …

A Rare Case Of Breast Carcinoma Metastasis Into A Meningioma In A 64-Year-Old Female Patient, Edwin Mogere, Miriam Mutebi, Allan Njau, Manel Haj Mansour
General Surgery, East Africa
This report discusses the occurrence of tumor-to-tumor metastasis—an atypical phenomenon in oncology where a secondary malignancy develops within an existing primary tumor. The case of a 64-year-old woman is presented, who, with a history of stage II invasive ductal carcinoma of the breast treated with mastectomy and chemoradiotherapy, developed neurological symptoms indicative of a secondary brain tumor. MRI and subsequent histopathological analysis post-craniotomy confirmed a meningioma with a metastatic breast carcinoma, demonstrating the clinical importance of considering tumor-to-tumor metastasis in similar patient histories.

Pathology, East Africa
Women of African descent have the highest breast cancer mortality in the United States and are more likely than women from other population groups to develop an aggressive disease. It remains uncertain to what extent breast cancer in Africa is reminiscent of breast cancer in African American or European American patients. Here, we performed whole-exome sequencing of genomic DNA from 191 breast tumor and non-cancerous adjacent tissue pairs obtained from 97 African American, 69 European American, 2 Asian American, and 23 Kenyan patients. Our analysis of the sequencing data revealed an elevated tumor mutational burden in both Kenyan and African …

Abstract: The clinical significance of the tumor-immune interaction in breast cancer is now established, and tumor-infiltrating lymphocytes (TILs) have emerged as predictive and prognostic biomarkers for patients with triple-negative (estrogen receptor, progesterone receptor, and HER2-negative) breast cancer and HER2-positive breast cancer. How computational assessments of TILs might complement manual TIL assessment in trial and daily practices is currently debated. Recent efforts to use machine learning (ML) to automatically evaluate TILs have shown promising results. We review state-of-the-art approaches and identify pitfalls and challenges of automated TIL evaluation by studying the root cause of ML discordances in comparison to manual TIL …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers
Primary adrenal angiosarcoma is an extremely rare malignant tumor with challenging diagnosis. A 66-year-old woman had a 4.3 cm right adrenal mass suspicious for adrenal cortical carcinoma. Pathological examination demonstrated a hemorrhagic adrenal cyst with numerous irregularly shaped anastomosing vascular channels lined by atypical endothelial cells that had frequent atypical mitotic figures (12/10 HPF, Ki67 10%). The tumor cells were positive for CD31, ERG, and FLI-1, but negative for adrenal and other tumor lineage markers by immunohistochemistry. NGS fusion gene testing ruled out epithelioid hemangioendothelioma. Accurate diagnosis and differential inclusion are important for appropriate treatment of this rare tumor.

The Journal of the Michigan Dental Association
Leukemia is the most prevalent malignancy of leukocytes and can occur in children and adults. Oral manifestations are part of the complexity of signs and symptoms in patients with leukemia and, in some patients, oral manifestations precede systemic manifestations. Oral signs of leukemia include spontaneous bleeding, gingival enlargement, and whiteness of the oral mucosa. Head and neck lymphadenopathy is common in patients with leukemia. Oral manifestations are the result of the direct invasion of immature cells in the oral cavity tissues or indirectly caused by the replacement of the normal blood cells for immature cells causing anemia, leucopenia, and thrombocytopenia. …

First line therapy for Acute Myeloid Leukemia (AML) is 7+3 regimen. It often cannot be used in elderly patients due to intensity. Venetoclax + hypomethylating agent (HMA) is approved for AML treatment in these patients. We investigate the efficacy of this treatment in a community setting where patients do not have the same resources available to them as a large academic center. Primary outcome was survival of patients greater than 60 years of age with a diagnosis of AML who received 7+3 therapy versus those who received venetoclax + HMA. Secondary outcomes included characteristics of those who received the two …

Cooper Rowan Medical Journal
This report aims to review a case of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) by comparing the patient's course with the current literature.
BIA-ALCL is a specific type of T-cell lymphoma that can develop after breast implantation, but has only recently been recognized within the last decade. Although overall rare, certain types of breast implants have increased association with developing subsequent lymphoma. This case occurred after mastectomy with breast reconstruction for unilateral invasive ductal carcinoma with a textured, saline Allergan breast implant. BIA-ALCL manifested and was symptomatic nine years after implantation.

Einstein Health Papers
Idiopathic pulmonary fibrosis (IPF) is a progressive disease of pulmonary scarring. New treatments slow disease progression and allow pulmonary fibrosis patients to live longer. Persistent pulmonary fibrosis increases a patient’s risk of developing lung cancer. Lung cancer in patients with IPF differs from cancers that develop in the non-fibrotic lung. Peripherally located adenocarcinoma is the most frequent cell type in smokers who develop lung cancer, while squamous cell carcinoma is the most frequent in pulmonary fibrosis. Increased fibroblast foci in IPF are associated with more aggressive cancer behaviour and shorter doubling times. Treatment of lung cancer in fibrosis is challenging …

Pediatric central nervous system (CNS) tumors represent the most common cause of cancer-related death in children aged 0-14 years. They differ from their adult counterparts, showing extensive clinical and molecular heterogeneity as well as a challenging histopathological spectrum that often impairs accurate diagnosis. Here, we use DNA methylation-based CNS tumor classification in combination with copy number, RNA-seq, and ChIP-seq analysis to characterize a newly identified CNS tumor type. In addition, we report histology, patient characteristics, and survival data in this tumor type. We describe a biologically distinct pediatric CNS tumor type (n = 31 cases) that is characterized by focal …

Internal Medicine
Primary rectal melanoma (PRM) is an uncommon malignancy whose etiology remains unknown. Most patients present with rectal bleeding. Distant metastasis is commonly seen in the lung and liver. The incidence rates for locoregional lymph node metastases on initial presentation are almost 60%. Histology and immunochemistry are useful and are the gold standard for diagnosis. The prognosis is very poor due to the late presentation of patients. Optimum surgical treatment remains controversial. Abdominoperineal resection was considered traditionally but over time, has been found to have no survival benefit. Current literature and studies, therefore, recommend wide local excision. The beneficial effects of …

Philp, Jennifer Johnson, Tingting Zhan, Joseph Curry, Ubaldo E. Martinez-Outshoorn
Department of Medical Oncology Faculty Papers
The most common cancers of the aerodigestive tract (ADT) are non-small cell lung cancer (NSCLC) and head and neck squamous cell carcinoma (HNSCC). The tumor stroma plays an important role in ADT cancer development and progression, and contributes to the metabolic heterogeneity of tumors. Cancer-associated fibroblasts (CAFs) are the most abundant cell type in the tumor stroma of ADT cancers and exert pro-tumorigenic functions. Metabolically, glycolytic CAFs support the energy needs of oxidative (OXPHOS) carcinoma cells. Upregulation of the monocarboxylate transporter 4 (MCT4) and downregulation of isocitrate dehydrogenase 3α (IDH3α) are markers of glycolysis in CAFs, and upregulation of the …

Concurrent P53 Mutation In Egfr Mutant Non-Small Cell Lung Cancer Is Associated With Resistance To First And Second Generation Egfr Tyrosine Kinase Inhibitors, A Meta-Analysis, Marissa Viola, Adam Kolatorowicz, Jun Wang
Research Day
Epidermal growth factor receptor (EGFR) mutant lung cancers tend to respond well to EGFR tyrosine kinase inhibitors (TKIs). However, resistance has been described. Molecular studies have revealed that concurrent mutations of tumor driver genes are associated with TKI resistance. To delineate the role of concurrent mutation of tumor suppressor gene p53 in TKI resistance, a meta-analysis was performed using published observations of EGFR mutant lung cancer patients treated with first or second generation TKIs. 31 studies are included in the analysis following a search of PubMed. Probability of TKI resistance and progress free survival (PFS) were compared in patients with …

Section of Haematology/Oncology
Eltrombopag has been used in ITP and found its use in AA armamentarium recently. We retrospectively analyzed 61 patients at a tertiary care center in Pakistan from January 2015 to January 2021. They included patients with severe AA who were refractory to at least one course of immunosuppressive therapy and persistent/chronic ITP who have received at least one previous treatment for ITP. Responses to Eltrombopag in our population were comparable to real-world experiences while tolerable hepatotoxicity and GI issues were notable. We found Eltrombopag to be a safe and efficacious agent for treating patients with ITP and AA.

Chronic granulomatous inflammation is a common finding in lymphoproliferative disorders (LPDs), but it is important to exclude coexisting mycobacterium tuberculosis (MTB) especially in patients from areas of high endemicity. This case emphasizes the relevance of performing MTB culture on bone marrow exhibiting LPD and concomitant granulomas

Altered fatty acid metabolism continues to be an attractive target for therapeutic intervention in cancer. We previously found that colorectal cancer (CRC) cells with a higher metastatic potential express a higher level of fatty acid translocase (CD36). However, the role of CD36 in CRC metastasis has not been studied. Here, we demonstrate that high expression of CD36 promotes invasion of CRC cells. Consistently, CD36 promoted lung metastasis in the tail vein model and GI metastasis in the cecum injection model. RNA-Seq analysis of CRC cells with altered expression of CD36 revealed an association between high expression of CD36 and upregulation …

The triad of weak/absent CD34, negative HLA-DR expression, and positivity to CD117 is pathognomonic for the diagnosis of acute promyelocytic leukemia. However, in rare cases, strong positivity to HLD-DR and CD34 may be noted.
