Primary malignant melanoma of the oral cavity is a rare neoplasm. The tumors tend to metastasize or locally invade tissue more readily than other malignant tumors in the oral region. The survival of patients with mucosal melanomas is less than for those with cutaneous melanomas. Tumor size and metastases are related to the prognosis of the disease. Early detection, therefore, is important.

Malignant fibrous histiocytoma is a rare neoplasm composed of fibroblasts and histiocytes. It assumes several histologic forms, which account for its various names and the difficulty in its diagnosis and classification. A case thought to be the sixth malignant fibrous histiocytoma involving the larynx is presented. The treatment of choice is wide excision with close follow-up examination.

Hodgkin's disease (HD) is a malignant neoplasm of lym-phoreticular cell origin, characterized by the presence of large mononucleated Hodgkin and giant multinucleated Reed-Sternberg cells [1]. Although it represents the most common subtype of malignant lymphoma in young people it has very

Primary apocrine adenocarcinoma (AA) is a rare malignant cutaneous neoplasm that typically arises in areas of high apocrine gland density such as the axillae and the anogenital region. Due to the nonspecific clinical manifestation of AA, the differential diagnosis may be broad. The rarity of this neoplasm has led to a relative lack of well-established histologic and immunohistochemical diagnost...

Oral malignant melanoma is a rare aggressive neoplasm of middle age, has predilection for the palate and maxillary gingiva or alveolar ridge and about 1/3rd of these neoplasms may develop from existing melanosis. A case of malignant melanoma in a 55 year old male is being reported. The patient was treated surgically. It is emphasised that the presence of pigmented oral mucosa must alert the cli...

Although extensive studies on the anemia and iron metabolism in patients with malignant neoplasms have been made, the pathogenesis of the anemia ob· served in cancer patients remains obscure. The first purpose of this paper is to elucidate the functional impairment in red cell production in patients with malignant neoplasm by means of ferrokinetic studies. The second one· is to clarify how the ...

In order to compare the impact of tobacco on cancer risk across different countries of the world, we abstracted the estimated adult (age 30 years and above) deaths attributable to tobacco for all-malignant neoplasm, trachea, bronchus and lung cancer, and all other malignant neoplasms from the WHO Global Report entitled, Mortality Attributable to Tobacco, which was recently published in 2012. In...

We report an instructive case of extraskeletal osteosarcoma in a 63-year-old African American male who presented after an episode of recent trauma, with clinical and radiological features characteristic of this neoplasm. Osteosarcoma is the most common primary malignant tumor of bone in young adults, but the extraskeletal variety is very uncommon. The radiological and pathological features of t...
