RESUMO
Squamous cell carcinoma is an extremely rare variant of breast cancer. Presence of unequivocal squamous differentiation should be observed to diagnose a case as squamous cell carcinoma of breast since focal squamous metaplasia is frequently seen in common variants of breast carcinoma. We report here two cases of squamous cell carcinoma of breast, one a primary metaplastic type and the other one metastatic from a carcinoma of the cervix.

Transitional cell tumours or Brenner tumours of ovary are uncommon neoplasms. Out of all the Brenner tumours less than 2% are either proliferating or malignant type. Borderline or malignant tumours occur in women who are on an average 10 years older than those with benign tumours. It is essential to categorise these tumours as benign, borderline or malignant type as the biologic behaviour and choice of surgery differs in all of the three categories. The gross and microscopic findings of a proliferating brenner tumour are reported here.

Hepatoblastoma accounts for only 0.5% of all paediatric tumours. The vast majority of these cases are seen under five years of age and a third of patients have some form of congenital anomaly syndrome or other childhood tumour. Most recent classification describes six subtypes of hepatoblastoma. Surgical resection is the best treatment preceded by accurate staging and chemotherapy or radiotherapy. Hepatoblastoma can be diagnosed by Fine Needle Aspiration Cytology (FNAC). We report here three cases of hepatoblastoma diagnosed by FNAC and subsequently confirmed by histopathology following resection of hepatic tumours.
