With the extensive industrial use of asbestos in this century and the long latent period (20-50 years) between exposure and tumor presentation, the incidence of malignant mesothelioma is now increasing. Thus, surgical pathologists are more frequently faced with the dilemma of differentiating mesothelioma from metastatic adenocarcinoma and spindle-cell sarcoma involving serosal surfaces. Electron microscopy is amodality useful in clarifying this problem.In utilizing ultrastructural features in the diagnosis of mesothelioma, it is essential to appreciate that the classification of this tumor reflects a variety of morphologic forms of differing biologic behavior (Table 1). Furthermore, with the variable histology and degree of differentiation in mesotheliomas it might be expected that the ultrastructure of such tumors also reflects a range of cytological features. Such is the case.

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.

Spindle cell carcinoma is a rare aggressive biphasic tumor, composed of neoplastic proliferation of both epithelial (squamous) and spindle cell population. It constitutes about 1% of all oral cavity tumors 2a and is almost rare on the tongue; only few cases have been reported so far. This variant of squamous cell carcinoma, comprises major diagnostic problems due to its varied histomorphology and resemblance to sarcomatous lesion; hence diligent screening and IHC markers are mandatory for its diagnosis.
