Apocrine carcinoma, which is strictly defined as over 90% of tumor cells showing apocrine differentiation, is a rare variant of breast cancer. Here we report an uncommon case in which apocrine carcinomas developed concurrently in both breasts; in addition, a sarcomatoid spindle cell lesion was coincident in the right breast. Both apocrine carcinomas were immunohistochemically negative for estrogen receptor (ER) and progesterone receptor (PgR), but diffusely positive for androgen receptor (AR), GCDFP-15, and HER2. The presence of intraductal components in bilateral carcinomas and the absence of lymph node metastasis suggested that they were more likely to be individual primary lesions rather than metastatic disease. The spindle cell lesion showed a relatively well-circumscribed nodule contiguous with the apocrine carcinoma. HER2 oncoprotein overexpression was observed not only in the apocrine carcinoma, but also in the spindle cell lesion. Since the spindle cell component was intimately admixed with apocrine carcinoma and had focal cytokeratin expression, we diagnosed it as metaplastic spindle cell carcinoma, which was originated from the apocrine carcinoma. To our knowledge, this is the first case report of a patient with synchronous bilateral apocrine carcinomas coinciding with metaplastic carcinoma.

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.

A variant of ductal carcinoma of the human breast which has been designated apocrine carcinoma has distinctive light and electron microscopic features. Such tumors comprise approximately 0.5% of breast carcinomas. Abundant cytoplasmic membrane bound vesicles (400-600 nm) with dense homogeneous osmophilic cores characterize these tumors. These granules are also seen in apocrine metaplastic breast epithelial lesions1 and appear to be responsible for the finely granular eosinophilic cytoplasm observed by light microscopy. A high content of intermediate affinity non-saturable 4S progesteroneestrogen binding protein (PEBP) in apocrine carcinoma has been reported.2 The present ultrastructural study evaluates the presence of apocrine granules in infiltrating ductal carcinoma (NOS) to determine if a correlation exists between apocrine granule content and the quantity of PEBP present.

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.
