RESUMO

Spindle cell lipoma is a histological variant of oral lipomas. In this report, we present the first case from the Gulf region with the most comprehensive literature review. Clinicians should consider rare tumors in the differential diagnoses of oral masses.

RESUMO

There is currently a dearth of information regarding lung cancer in never smokers (LCINS). Additionally, there is a difference in somatic mutations, tumour mutational burden, and chromosomal aberrations between smokers and never smokers (NS), insinuating a different disease entity in LCINS. A better understanding of actionable driver alterations prevalent in LCINS and the genomic landscape will contribute to identifying new molecular targets of relevance for NS that will drastically improve outcomes. Differences in treatment outcomes between NS and smokers, as well as sexes, with NSCLC suggest unique tumour characteristics. Epidermal growth factor receptor (EGFR) tyrosine kinase mutations and echinoderm microtubule-associated protein-like 4 anaplastic lymphoma kinase (EML4-ALK) gene rearrangements are more common in NS and have been associated with chemotherapy resistance. Moreover, NS are less likely to benefit from immune mediators including PD-L1. Unravelling the genomic and epigenomic underpinnings of LCINS will aid in the development of not only novel targeted therapies but also more refined approaches. This review encompasses driver genes and pathways involved in the pathogenesis of LCINS and a deeper exploration of the genomic landscape and tumour microenvironment. We highlight the dire need to define the genetic and environmental aspects entailing the development of lung cancer in NS.

RESUMO

Multiple primary tumors are defined as multiple simultaneous (within 6 months) or heterogeneous tumors. Case presentation: Here, the authors present the case of a 58-year-old Saudi female patient with Li-Fraumeni syndrome who has multiple primary tumors. Clinical discussion: The surgical cytoreduction or 'debulking' technique is the main treatment option started in individuals with High Grade Serous Ovarian CanceR. This surgical strategy aims to completely remove all disseminated tumor masses that are present in the patient's peritoneal cavity on a macroscopic level. Conclusion: In conclusion, in our case, she has developed her ovarian cancer 27 years after her breast cancer got treated. This was already stage IIIB to stage IV. If it was not for her incidental discovery of her urinary bladder cancer, which is most likely is a long-term sequel of using cyclophosphamide 27 years ago.Multiple primary tumors are defined as multiple simultaneous (within 6 months) or heterogeneous tumors.

RESUMO

Neuroblastoma is the most common extracranial, intrabdominal, suprarenal solid tumor of childhood. It usually presents with painless abdominal mass with or without abdominal pain. We report an unusual subtle cervical lymph nodes enlargement associated with fever and joint pain. Neuroblastoma usually starts in the adrenal glands. What is unique in our case is that the presentation is without a primary tumor. We present a case of 4-year-old female Egyptian complaining of recurrent pattern of fever and generalized joint pain, with lower neck swelling for 1-month duration. Laboratory investigations revealed a normochromic normocytic anemia and increased inflammatory markers. Immunohistochemistry staining and immunophenotyping of the cervical lymph nodes and bone marrows confirmed the diagnosis of Neuroblastoma. This case report highlights the importance of recognizing the possibility of a metastatic neuroblastoma without primary tumor in children who presented solely of lymphadenopathy.
