Abstract

- Superficial CD34-positive fibroblastic tumor (SCD34FT) is a rare soft tissue neoplasm that shows overlapping features with PRDM10-rearranged soft tissue tumor (PRDM10-STT). This study characterizes the clinicopathologic, immunohistochemical, and molecular features of SCD34FT in a series of 59 cases. Fluorescence in situ hybridization to assess for PRDM10 rearrangement was performed in 12 tumors. Immunohistochemistry for CADM3 and WT1 was performed; CADM3 was also assessed in histologic mimics. Our cohort of 33 male and 26 female had a median age of 42 (range: 14 to 85) years. Tumors were most commonly located in the lower limb (73%), upper limb (8%), back (7%), and supraclavicular region (3%). The median tumor size was 3.0 cm (range: 1.0 to 9.0 cm). Clinical follow-up in 32 patients (median duration: 26 mo) revealed 2 local recurrences (6%). One patient developed regional lymph node metastases which were completely excised. Microscopically, SCD34FT comprised spindled and pleomorphic cells with glassy cytoplasm and occasional granular cell change. Fluorescence in situ hybridization confirmed PRDM10 rearrangement in 3/8 cases (38%). SCD34FT frequently expressed CADM3 (95%) and WT1 (75%). CADM3 was less diffusely positive in pleomorphic hyalinizing angiectatic tumor (40%), pleomorphic liposarcoma (20%), and undifferentiated pleomorphic sarcoma (10%). We corroborate that SCD34FT is indolent but may rarely metastasize to lymph nodes without adverse outcomes. CADM3 and WT1 may be useful in the distinction from histologic mimics. Since cases of SCD34FT with and without demonstrable PRDM10 rearrangement were clinicopathologically indistinguishable, our study further supports that SCD34FT and PRDM10-STT likely constitute a single entity.
