Infective dermatitis associated with HTLV-1 is a rare and severe chronic disease characterized by recurrent chronic eczema (with erythematous, scaly and crusted lesions) mainly affecting seborrheic areas (e.g. scalp, forehead, eyelids, paranasal and periauricular skin, neck, axillae, and groin), a generalized fine papular rash, chronic nasal discharge with crusting of the anterior nares, and non-virulent <i>Staphylococcus aureus</i> or beta-hemolytic <i>Streptococcus</i> infections, thought to be a result of HTLV-1-induced immunosuppression. Lymphadenopathy, anemia, mild to moderate pruritus and increased incidence of other infections (e.g. crusted scabies) have also been reported in some patients. Patients may subsequently develop other HTLV-1 associated conditions such as adult T-cell leukemia/lymphoma and tropical spastic paraparesis (see these terms). [from ORDO]

A carcinoma that arises from the intrahepatic bile duct epithelium in any site of the intrahepatic biliary tree. Grossly, the malignant lesions are solid, nodular, and grayish. Morphologically, the vast majority of cases are adenocarcinomas. Signs and symptoms include malaise, weight loss, right upper quadrant abdominal pain, and night sweats. Early detection is difficult and the prognosis is generally poor. [from NCI]

Representative examples of malignant neoplasms include intrahepatic and extrahepatic cholangiocarcinoma. [from NCI]
