Adnexal carcinomas of the skin are rare and they derive from structures such as sweat glands, sebaceous glands, and hair follicles. Adnexal tumors represent 1-2% of skin cancers. Between 1998 and 2004, eight patients with malignant adnexal tumors of the head and neck were treated in the Plastic Surgery Service in Argerich Hospital in Buenos Aires, Argentina. Four (50%) of them had malignant cyl...

EpCam is a transmembrane epithelial adhesion molecule present on all non-squamous epithelial cells. It is often overexpressed in certain carcinomas, such as breast and colon, and in dermatology, eg, basal cell carcinoma (BCC). Various monoclonal antibodies have been used to detect EpCam, including BerEP4 and epithelial specific antigen. We compared anti-EpCam clones, BerEP4, and epithelial spec...

Muir-Torre Syndrome is defined by the coexistence of sebaceous skin tumors and internal malignancies. Mutations in the DNA mismatch repair genes are found in the inherited form of the disease, resulting in the absence of crucial enzymes involved with DNA replication process. This case describes a patient with sebaceous adenoma and colorectal carcinoma, meeting the criteria for Muir-Torre Syndro...

A malignant transformation is known to occur in many nevi such as a sebaceous nevus or a basal cell nevus, but a verrucous epidermal nevus has only rarely been associated with neoplastic changes. Keratoacanthoma, multifocal papillary apocrine adenoma, multiple malignant eccrine poroma, basal cell carcinoma and cutaneous squamous cell carcinoma (CSCC) have all been reported to develop from a ver...

Sebaceous gland carcinoma of the eyelid is a rare slow-growing tumor and is one of the most aggressive malignancies of the eyelid. Diagnosis is often delayed because it can be confused with other periocular lesions. We report the case of a 78-year-old female who presented for the anesthetic aspect of a nodular tumor on the right upper eyelid occurring one year earlier. The patient was treated f...

Sebaceous metaplasia in canine mammary tumors is a rare condition with only 1 case documented. The current study describes a case of sebaceous metaplasia in a mammary gland carcinoma of an 8-year-old intact, nulliparous female Poodle dog with a subcutaneous tumor located in the left fifth mammary gland. The lesion measured 0.7 cm × 0.5 cm × 0.6 cm in diameter, was firm, circumscribed, painless,...

Sebaceous carcinoma is a rare and aggressive skin tumor. It can be located in any area of the body, the most commonly involved area being the periorbital region. It does not entail a typical clinical presentation, which explains the often late diagnosis. The aim of this report is to outline the rarity of the disease and its atypical clinical description, since to this day, inguinal ulcers with ...

PURPOSE To report a successful eyelid reconstruction performed using the residual tarsus after excision of a sebaceous gland carcinoma. CASE REPORT An 86-year-old woman presented with a sebaceous gland carcinoma of the upper eyelid margin. After excision of the tumor, she underwent reconstructive surgery of the superior eyelid performed using the residual tarsus. Because the tumor was localiz...

The sebaceous nevus of Jadassohn is a congenital hamartoma that may develop into a malignant cutaneous neoplasia. Photodynamic therapy is used to treat actinic keratoses and superficial or nodular basal cell carcinomas, and the cutaneous field cancerization can be observed using the Wood’s lamp during the performance of the technique. This article describes a case of photodynamic therapy used i...
