Reportability/Histology--Soft Tissue: Is superficial CD34 positive fibroblastic tumor reportable and if so what histology code should be used? See Discussion.
Patient had a left thigh soft tissue mass excision on 7/24/24 and was diagnosed with superficial CD34 positive fibroblastic tumor. Margins were narrowly free of disease. Tumor size was 5.5 cm x 4.4 cm x 3.9 cm. The diagnosis was confirmed.
Do not report superficial CD34-positive fibroblastic tumor (8810/1) of the thigh.

multifocal intraepithelial carcinoma. The foci of intraepithelial carcinoma
