Purpose: Report the unusual presentation, clinical course, and cytogenetic abnormalities in a child with multifocal osteosarcoma.
Patients And Methods: A 10-year-old boy had multifocal osteosarcoma involving the entire skeleton, pleura, bone marrow, and lungs. He had marked anemia, thrombocytopenia, and severe hypocalcemia at diagnosis.
Results: Despite aggressive chemotherapy, he died from progressive disease 1 month after diagnosis. Cytogenetic analysis of tumor cells within the pleural fluid showed multiple chromosomal abnormalities with amplification of the c-myc oncogene.
Conclusion: Multifocal osteosarcoma should be considered in the differential diagnosis of a child with pancytopenia and multiple bone lesions. Amplification of the c-myc oncogene may have had a significant role in the pathogenesis, etiology, and rapid progression of this patient's multifocal disease. Additional studies will be needed to determine the biologic significance of c-myc amplification in multifocal osteosarcoma.

During routine veterinary inspection of fish from fishing boats, fish auction yards, and fish landing stations, as well as the large fish market for detection of fish diseases, abnormalities and/or overgrowth in body surfaces and evaluation of hygienic conditions and fish quality at El-Jubail Province, Saudi Arabia., external neoplastic overgrowths were observed in two fish species, giant sea catfish (Arius thalassinus) and Delagoa threadfin bream (Nemipterus bipunctatu). In both fishes, the neoplasms appeared as bony masses, and it was hard in its consistency.

Purpose: Describe clinical characteristics and outcome of Li-Fraumeni syndrome (LFS)-associated osteosarcomas.
Methods: TP53 germline pathogenic/likely pathogenic variant carriers diagnosed with osteosarcoma in France between 1980 and 2019 were identified via the French Li-Fraumeni database at Rouen University Hospital. Sixty-five osteosarcomas in 52 patients with available clinical and histological data were included.

Pain, a prevalent and debilitating symptom in cancer patients, significantly diminishes the quality of life for both individuals and their families. Addressing this critical issue, our study presents the case of a 15-year-old diagnosed with synchronous multifocal multicentric osteosarcoma. We utilized radiofrequency ablation of bilateral splanchnic nerves, a strategy of multimodal pain and palliative care.

Ewing sarcoma is an uncommon neoplasm considered in the differential diagnosis of tumors with "small round cell" morphology, but its occurrence in the gynecologic tract has only been sporadically documented. Herein, we describe the largest cohort of Ewing sarcoma localized to the female genital tract to date, and emphasize their clinicopathologic resemblance to more common gynecologic neoplasms. Ewing sarcoma (n=21) was retrospectively identified from 5 institutions.
