<h3>Introduction</h3> Pleomorphic hyalinizing angiectatic tumour (PHAT) is an uncommon low to intermediate malignancy of soft tissues of unknown histogenesis with a predilection for the subcutaneous and intramuscular soft tissues of the extremities (most commonly the lower extremities) and trunk in adults<sup>1,2</sup> (mean age 51<sup>1</sup>). They are slow growing and are often present for several years before coming to clinical attention <sup>1</sup>. PHAT has a high potential for local recurrence (33-50%) with the recurrent tumour resembling the primary in most cases but occasionally may recur as a high grade sarcoma (pleomorphic sarcoma)<sup>1</sup>. Since they were described in 1996 by Smith <i>et ál</i>., there have been no reported cases of metastasis. <h3>Clinical history</h3> We report a PHAT in a 55-year-old gentleman who had a subcutaneous lump removed from his left shoulder, clinically suspected to be a lipoma. <h3>Pathologic features</h3> Grossly the tumour measured 40 mm with a tan, lobulated cut surface, which showed a focal area of haemorrhage. Microscopically the tumour showed characteristic features of PHAT which include clusters of ectatic thin walled blood vessels surrounded by perivascular hyaline material within a stroma composed of plump, oval-spindled and pleomorphic cells showing minimal mitoses and a variable inflammatory infiltrate. Tumour cells showed positive staining for Vimentin and CD34 but were negative for CD31, S100, Melan A, Actin, Desmin and Cytokeratins (CK34, AE1/3), confirming the diagnosis. <h3>Discussion</h3> Clinically, PHAT may mimic several benign or malignant tumours including a lipoma, haematoma, Baker's cyst, desmoid, and Kaposi's sarcoma making tissue biopsy necessary for diagnosis<sup>3</sup>. The histologic differential diagnosis includes schwannoma and malignant fibrous histiocytoma<sup>1,4</sup>. Other soft tissue tumours resembling PHAT include myxoid or pleomorphic liposarcoma, myxoid synovial sarcoma, myofibroblastic sarcomas, solitary fibrous tumour, extra-skeletal myxoid chondrosarcoma and angiomatoid fibrous histiocytoma<sup>2</sup>. <h3>Conclusion</h3> PHAT is a rare tumour that may mimic other benign and malignant tumours clinically and histologically. Identification of PHAT and differentiating it from its benign and malignant mimics is important because of its high potential for recurrence and high grade transformation. The treatment of choice is wide local excision.
