Study of human sebaceous gland physiology and pathophysiology is limited by lack of an adequate animal model. This study was designed to develop an animal model using human face skin grafted onto the nude mouse to study human sebaceous glands. Full-thickness human face skin was grafted onto 60 adult male nude mice. 4 wk after grafting, androgens, which are known to stimulate sebaceous glands, w...

BACKGROUND Sebaceous carcinoma (SC) is a rare malignancy, occurring predominantly in eyelids. Till date, only 25 cases of sebaceous carcinoma (SC) of the parotid gland have been reported in world literature. CASE PRESENTATION A 33 year-old male presented with left sided laterocervical mass. Clinical examination showed enlargement of the left parotid gland, with cervical lymphadenopathy. No sk...

BACKGROUND Several case reports document successful treatment of sebaceous hyperplasia with the pulsed-dye laser. Moreover, noninvasive real-time confocal laser scanning microscopy elucidates the vascular nature of these lesions and their pathophysiologic response to treatment mediated by vessel coagulation. METHODS Ten patients with 29 lesions of sebaceous hyperplasia were treated with 3 sta...

A 37-year-old woman underwent surgery to remove bilateral vulvar masses. The masses were firm, non-tender, and immobile. Pathologic finding was a well-delineated creamy grayish mass with a homogenous grayish solid surface and mild edema, chronic inflammatory infiltration, and focal dilation of the ducts with squamous metaplasia. The diagnosis was hyperplastic and hypertrophied Bartholin’s gland...

Over the 42 month period from January 2003 to June 2006, a total of 2,952 canine biopsy specimens were received from the Veterinary Medical Teaching Hospital of Seoul National University and from veterinary practitioners across the nation. Out of these, 748 (25.34%) cases were diagnosed as canine cutaneous tumors in the Department of Veterinary Pathology, College of Veterinary Medicine, Seoul N...

We experienced two cases of cutaneous dermoid cysts (DC). To elucidate the histogenesis of DC, we have studied cytokeratin (CK) expression in DC using ten different anti-keratin antibodies against CK1, 7, 8, 10, 14, 15, 16, 17, 18 and 19, and anti-filaggrin (filament aggregating protein) antibody. In the cyst wall of DC, CK1 and 10 were expressed in suprabasal layer, and CK14 was limited to the...
