Biopsies on Beatrice's tumors came back, one came back as a fatty tumor the other came back as an incredibly rare type tumor a lymphangiosarcoma and the advise to see an oncologist
DESCRIPTION/MICROSCOPIC FINDINGS/COMMENTS: MICROSCOPIC DESCRIPTION: Adipose tissue (unmarked jar): Infiltrating and expanding the adipose tissue is a nonencapsulated, poorly demarcated, and moderately cellular neoplasm. The neoplastic cells form interconnecting cleft-like vascular channels or spaces with frequent blind ended trabeculae, lining dense collagenous stroma or preexisting dermal collagen bundles. The neoplastic cells are spindloid with indistinct cell borders, small to moderate amounts of eosinophilic cytoplasm, and an oval nucleus with finely stippled chromatin and small basophilic nucleoli. There is minimal anisocytosis and anisokaryosis, and mitotic figures are rare. The lumina of the cleft-like channels is generally empty, with few scattered foamy macrophages and rare erythrocytes.
MICROSCOPIC FINDINGS: Lymphangioma or lymphangiosarcoma
MARGINS: Neoplastic tissue extends to lateral and deep surgical borders. Total excision of the lesion is not proven histologically.
COMMENTS: Lymphangioma and lymphangiosarcomas are tumors of lymphatic endothelium. These are rare tumors in all species. The distinction between benign and malignant tumors can be minimal. The infiltrative growth of these tumors makes borders difficult to assess. Recurrence is common, but metastasis is rare. Early surgical excision can be curative. Consultation with an oncologist on this case may provide additional diagnostic and therapeutic advice.
