Mixed adenoneuroendocrine carcinoma is a rare neoplasm with both epithelial and neuroendocrine components. To date, only a few cases of this neoplasm have been reported in the literature among which gastric mixed adenoneuroendocrine carcinoma is very rare. We are reporting a case of gastric mixed adenoneuroendocrine carcinoma with squamous cell differentiation. Histopathological features, biological behaviour and the treatment of this rare tumour type have been discussed briefly.

Abstract BackgroundBreast cancer with squamous differentiation is a relatively rare condition. Clinically, lymph node metastasis is uncommon in metaplastic carcinoma We treated a patient with lymph node metastasis of the ductal carcinoma component of invasive ductal carcinoma with squamous cell differentiation. Case Report: An 84-year-old postmenopausal Japanese woman had a left-breast mass with an enlarged lymph node in the left axilla. A biopsy revealed an invasive ductal carcinoma with squamous cell differentiation. A left mastectomy with axillary lymph node dissection was performed. The Histological evaluation revealed invasive ductal carcinoma with squamous cell differentiation. One lymph node was positive for metastasis consisting of ductal carcinoma without squamous cell differentiation.Conclusion: This case suggests that lymph node metastasis in ductal carcinoma with squamous differentiation may first involve the ductal carcinoma component and then differentiation may occur in the in volved lymph nodes. This is an interesting case highlighting the process of the progression of lymph node metastasis in cases with breast cancer with squamous cell differentiation.

Steroid cell tumour of the ovary is an extremely rare tumour. They are classified into three types with the commonest, the steroid cell tumour not otherwise specified (NOS) consisting approximately 60% of them. They occur mostly in middle age, are mostly benign and mostly cause virilising symptoms though a small proportion can present with oestrogenic effects. Diagnosis is based on presence of symptoms, presence of specific histopathological features with absence of certain histopathological features and positive specific immunostaining results. Here the author reports a case of a 42-year old woman with abdominal mass but without virilising symptoms but on whom a diagnosis of ovarian steroid cell tumour was reached by histopathological analysis which revealed presence of specific histopathological features with absence of certain histopathological features.

 Osteosarcoma of jaw is a rare malignant condition of osteoid tissue with same histopathological features but different biological behaviour compared to long bone. It has characteristic clinical, radiographic and histopathologic features and treatment after early diagnosis followed by surgery (with negative margin) combined with chemotherapy or ra­diotherapy has better prognosis and survival rate. Here we report the case of osteosarcoma of mandible after tooth extraction in a 55-year-old female and treated by surgery
