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...

Sebaceous glands have been extremely rare findings in the female genital system. Excluding the vulva and recent findings, very few cases have been described. The origin of the lesions remains a topic of speculation. However, it appears that prolonged irritation induces a metaplastic response in the ectocervical epithelium. A new case of sebaceous glands in the ectocervix of a 46-year-old woman ...

The presentation herewith as scripted is to describe a case with Nevus sebaceous with oral manifestations. Nevus Sebaceous or Jadassohn's nevus is an epidermal nevus with predominant sebaceous glands seen histologically. Reports of oral involvement have been few ranging from papillomatous growths of the tongue, gingiva, palate to dental abnormalities such as anodontia and dysodontia. The presen...

Sebaceous glands perform complex functions, and they are centrally involved in the pathogenesis of acne vulgaris. Current techniques for studying sebaceous glands are mostly static in nature, whereas the gland's main function-excretion of sebum via the holocrine mechanism-can only be evaluated over time. We present a longitudinal, real-time alternative-the in vivo, label-free imaging of sebaceo...

Diffuse sebaceous-gland hyperplasia is a rarevariant of sebaceous-gland hyperplasia that isdistinct from the well-known circumscribed type.The term presenile sebaceous hyperplasia has beenutilized to describe this entity that is distinguishedby specific features, which include confluence oflesions that results in the formation of large plaqueson the face, the sparing of periorificial regions, a...

Ocular sebaceous adenocarcinoma is a rare malignant tumor. We report an unusual case of orbital sebaceous adenocarcinoma in a 48-year-old woman. The patient underwent F-18 2-fluoro-2-deoxy-glucose positron emission tomography/computed tomography ((18)F-FDG-PET/CT) to determine the initial clinical stage. (18)F-FDG-PET/CT showed strong uptake in the orbital lesion, but neither regional lymphatic...

Lymphadenoma of the salivary gland is a very rare (or possibly even under-reported) tumour with only sparse reports found in the literature. It is not mentioned in most textbooks on salivary gland tumours or head and neck pathology. The 1996 Armed Forces Institute of Pathology fascicle briefly discusses the entity as a variant of sebaceous lymphadenoma (‘‘lymphadenoma that lacks sebaceous diffe...

      Abstract: development of squamous cell carcinoma from sebaceous cyst is uncommon.in this report , we report a77- old female patient who has had a sebaceous cyst for 20 years. The cyst started to grow during the last year. The patient underwent an operation for excision biopsy and The diagnosis was squamous cell carcinoma.
