title: Multiple low-grade sarcomas of fibroblastic type in the setting of HIV and acquired epidermodysplasia verruciformis.
abstract: A 46-year-old white male with a history of HIV (CD4 245), acquired epidermodysplasia verruciformis, anal carcinoma in situ, hepatitis B and C presented with 3 asymptomatic, nontender, firm pink/skin-colored nodules involving the arm, left lateral leg, and right third finger. One year later, he developed a similar lesion on his right medial lower leg. Excisional biopsy of one of the lesions showed an atypical spindle cell neoplasm of the dermis compatible with a low-grade sarcoma of fibroblastic origin. Testing for human herpes virus-8, 23 human papillomavirus types, Epstein-Barr virus, and FUS fusion protein were negative. The patient underwent diagnostic imaging with computed tomography scans of the chest, abdomen, and pelvis along with positron emission tomography scan to ensure that there was no other occult primary tumor, all of which were negative. The lesions were excised and have not recurred with 3 years of follow-up. The best histopathologic term for these lesions is multiple low-grade sarcomas of fibroblastic phenotype. They have been proven to be nonaggressive, with little or no metastatic potential. This is a neoplastic process that has not been well defined in the literature. To our knowledge, there are no previous reports of these lesions occurring in multiple sites or in an HIV-positive patient.
