Dual-Positive (CD4+/CD8+) Acute Adult T-Cell Leukemia/Lymphoma Associated with Complex Karyotype and Refractory Hypercalcemia: Case Report and Literature Review.

We describe a rare case of adult T-cell leukemia characterized by an expansion of CD4+ CD8+ double-positive lymphocytes associated with human T-lymphotropic virus type 1 (HTLV-1) and a complex karyotype in a 43-year-old Caribbean male who was initially admitted to our hospital with significant lethargy, visual disturbances, dysphagia, right facial palsy and numbness in both feet for 3 days. He was found to have severe hypercalcemia (15.6 mg/dl).

Emerging therapies in the treatment of locally advanced squamous cell cancers of head and neck.

Head and neck squamous cell cancers (HNSCCs) represent 4 to 5% of all solid malignancies. Despite improvements in diagnostic techniques, 60% of patients will present with locally advanced HNSCCs with a median survival of about 12 months and 5-year overall survival of approximately 10-40%. Recent clinical trials have altered the treatment landscape by refining existing forms of radiation, incorporation of IMRT, choice of chemotherapeutic agents, introduction of biological and targeted therapy, immunotherapy and gene therapy.

Transitional Cell Carcinoma of the Bladder Manifestating as Malignant Lymphoma with Generalized Lymphadenopathy.

Bladder cancer usually spreads via the lymphatic and hematogenous routes, the most common sites of metastases of urinary bladder cancers being the regional lymph nodes, liver, lung, bone, peritoneum, pleura, kidney, adrenal gland and intestines. Generalized lymph node metastasis of transitional cell cancer of the bladder is extremely rare. According to our literature search, there has been no case report of transitional cell cancer of the bladder that manifests as an extensive large lymph node metastasis involving the intraparotid, supraclavicular thoracic inlet, axillary and regional abdominal and pelvic lymph nodes without bone or visceral organs involved.
