title: Jugulo-sternal-gland tumors in male tree shrews (Tupaia belangeri).
abstract: Adenocarcinomas of the jugulo-sternal glands were observed in seven adult male tree shrews (Tupaia belangeri) at biopsy or necrospy. Five of these tumors were classified as carcinomas of the sebaceous gland compartment; one was diagnosed as a papilliform adenoma of apocrine (monoptychic) sweat glands; and one was of a mixed sebaceous gland/apocrine sweat gland structure. Four sebaceous gland carcinomas had histologic evidence of vascular invasion; one had metastasized to the regional lymph nodes and lungs and had also invaded the thoracic muscles.
