Histopathologic differentiation between deep dermal or subcuticular equine sarcoids (ie, nodular sarcoids) and other spindle cell tumors in the dermis and subcutis such as peripheral nerve sheath tumors (PNSTs) can be challenging based on morphologic criteria alone. It has been proposed that polymerase chain reaction (PCR) for bovine papillomavirus (BPV) DNA and S100 immunohistochemistry be used as diagnostic tests to separate equine sarcoids from PNSTs. We reviewed 197 skin-associated spindle cell tumors (ie, soft tissue sarcomas), including PNSTs and sarcoids, received at the University of Florida between 1995 and 2013 and performed BPV PCR and S100 immunohistochemistry on archived paraffin-embedded tissues. We found that BPV DNA was demonstrable in 70% of the sarcoids, 59% of the PNSTs, 37% of the fibrosarcomas, and 22% of other tumors (myxosarcomas, fibromas, and other sarcomas) diagnosed on histomorphologic characteristics. Positive S100 staining was only seen in 12 tumors in the study (5 fibrosarcomas, 3 sarcoids, 2 PNSTs, and 2 other sarcomas). The results demonstrate that BPV is associated with many skin-associated spindle cell soft tissue tumors in horses in addition to sarcoids. S100 was rarely expressed in equine soft tissue sarcomas in the skin but was expressed in many tumor types, including PNSTs and sarcoids. Because 41% of the PNSTs classified by histomorphology in this study were BPV negative and 94% were S100 negative, it is reasonable to classify these as soft tissue sarcomas with nerve sheath tumor histomorphology rather than as either PNSTs or sarcoids.

Inflammatory myofibroblastic tumour (IMT) occurring at intraabdominal sites in children has rarely been described. Inflammatory pseudotumour is a soft tissue lesion that may be confused with a sarcoma. It is abbreviated as IMT. Inflammatory myofibroblastic tumour, also known as soft tissue tumours, atypical fibromyxoid tumours, pseudosarcomatous fibromyxoid tumour, plasma cell granuloma, pseudosarcomatous myofibrotic proliferation, post-operative spindle cell nodules. In this paper, we describe a case of inflammatory myofibroblastic tumour (IMT) with an unusual constellation of clinical, pathological findings. A 10-year-old girl had an 7-cm intraabdominal mass accompanied by severe anemia, fever, constipation, weight loss, thrombocytosis, elevated erythrocyte sedimentation rate. Laparotomy was performed. The final pathologic diagnosis was IMT. At the most recent follow up (12months) after excision of the tumour, the patient was symptom-free and there was no evidence of tumour recurrence.J. Paediatr.
